Problem with joining several tables
Hello PL/SQL gurus and experts.I use Oracle Database 11 g Enterprise Edition Release 11.2.0.1.0 - 64-bit Production version
I followed two tables
Student-
drop table TT3;
create table TT3(FeesCntlr,CommCntlr,LatePayCntlr,Name,Age) as select

I am looking forward to the fees, commissions and surcharges output for each student and by using the following SQL code.select t3.Name,t3.age,t4.Fees
from tt3 t3, tt4 t4
where t3.FeesCntlr=t4.FeesCntlr
union
select t3.Name,t3.age,t4.Commission
from tt3 t3, tt4 t4
where t3.CommCntlr=t4.CommCntlr
union
select t3.Name,t3.age,t4.Latepayment
from tt3 t3, tt4 t4
where t3.LatePayCntlr=t4.LatePayCntlr
but it gives me not the correct result and showing a lot of entries and display only the "Expenses" column then only I'm looking for the output to be -Name Age Fees Commission Laypayment

Hello
I see your table TT3 has duplicated lines. A reason for this?
Rather than run a separate, I created it without duplicated lines:
create table TT3(FeesCntlr,CommCntlr,LatePayCntlr,Name,Age) as select
1,11,21,'Mike',25 from dual union all select
2,12,22,'Clark',26 from dual union all select
4,17,27,'Ussan',28 from dual union all select
5,13,21,'Linda',29 from dual union all select
6,14,24,'Obrek',35 from dual union all select
7,15,25,'Batty',45 from dual union all select
8,16,26,'Nicky',38 from dual;
create table TT4(FeesCntlr,CommCntlr,LatePayCntlr,Fees,Commission,Latepayment) as select
1,11,21,25000,4456,223 from dual union all select
2,12,22,356000,3321,0 from dual union all select
1,11,21,456000,223,33 from dual union all select
4,17,27,32890,0,0 from dual union all select
5,13,21,0,778,223 from dual union all select
6,14,24,332567,222,0 from dual union all select
7,15,25,228990,22,0 from dual union all select
8,16,26,0,0,2234 from dual union all select
1,11,21,22345,0,0 from dual union all select
2,12,22,2222789,2,33 from dual union all select
1,11,21,334567,0,0 from dual union all select
4,17,27,9987250,2,33 from dual union all select
5,13,21,2227890,0,0 from dual union all select
6,14,24,2278231,0,3345 from dual union all select
7,15,25,223456,2,0 from dual union all select
8,16,26,223890,0,0 from dual ;
SELECT t3.name, t3.age, SUM (t4.fees) fees, SUM (t4.commission) commission
, SUM (t4.latepayment) latepayment
FROM tt3 t3, tt4 t4
WHERE t3.feescntlr = t4.feescntlr
AND t3.commcntlr = t4.commcntlr
AND t3.latepaycntlr = t4.latepaycntlr
GROUP BY t3.name, t3.age;
Output:

Hello
We are working on a data warehousing project and wonder how do to join several tables that each are versioned separately (type SCD 2 with a valid and valid to date).
Because for example, we get our client from a single source of information (id customer, name, etc.) and the information on the rate of customer from another source. The sources are different, we have the separate tables for them and each of them gets versioned independently.
Here's my customer table (with its own valid and valuable to the columns).
ID Name of the customer Valid from Valid until the 1 CitiBank 1 JANUARY 14 JANUARY 1, 15 1 New CitiBank 2 JANUARY 15 FEBRUARY 1, 15 1 Latest CitiBank 2 FEBRUARY 15 APRIL 1, 15 And similarly the Client side ID and rating information.
ID Note Valid from Valid until the 1 Platinum 1 JANUARY 14 FEBRUARY 1, 14 1 Premium FEBRUARY 1, 14 1ST MARCH 15 I want to merge the two tables above and present information at a glance. I have some difficulty to determine validates the valid columns.
ID Name of the customer Note Valid from (Calculated) Valid until the (calculated) 1 CitiBank Platinum 1 JANUARY 14 FEBRUARY 1, 14 1 CitiBank Premium FEBRUARY 1, 14 JANUARY 1, 15 1 New CitiBank Premium 2 JANUARY 15 FEBRUARY 1, 15 1 Latest CitiBank Premium 2 FEBRUARY 15 1ST MARCH 15 And it's the query I used to get the above result:
SELECT client. id ,
customer . name ,
CRM . level ,
Greatest (client. vld_fm , crm. vld_fm ),
Least (client. vld_to , crm. vld_to )
DE client client,
client_rating crm
OÙ client. id = crm. id
AND ( client. vld_fm <= crm. vld_fm
AND client. vld_fm <= crm. vld_to
AND client. vld_fm >= crm. vld_fm
AND client. vld_fm >= crm. vld_to )
OR ( client. vld_fm BETWEEN crm. vld_fm AND crm. vld_to )
OR ( client. vld_to BETWEEN crm. vld_fm AND crm. vld_to );
The problem is we have several data sources (and each with its own versions) and joins become so very very complex. Is there a better way to write the query?Or maybe a better way to design our tables?
Thanks for your help.

Hello
you only need ranges that overlap to join.
Re: How do to sql query in a loop
Is a simpler way to test if the x_start to x_stop range comes into conflict with the range of y_start to y_stop
WHERE x_start <= y_stop AND y_start <= x_stop
In other words, two overlapping if and only if everyone will start before the other ends one. If this is not obvious (and it was certainly not clear to me when I heard it), then look at it this way: two ranges are not overlapping if and only if one of them starts after the end of the other.

Update statement with joins of tables and where Clause
Hi, I have MS SQL background and I try to execute an update statement in Oracle with joins of tables. However, the syntax below does not work but I think it works for MS SQL.
Basically, the base table must be attached to a master table trend with monthly snapshots, an account will be only an entry for a given date monthly. Where clause must be limited to accounts within a certain range of interest rates.
The first approach returns command SQL ORA-00933 not correctly completed, and the second approach returns ORA-01427 row below query returns multiple rows. Can anyone help? Thanks in advance!
1:
Update PenaltyAll
Set a.indicator = month (b.)
of PenaltyAll an inner join Master b on a.acctno = b.accountnumber
where a.monthend='01/31/2009' and b.date='12/31/2008' and b.apr < 20
2:
Update PenaltyAll
adjustment indicator =
(select to_char (b., 'MM')
of PenaltyAll an inner join Master b on a.acctno = b.accountnumber
"where to_char (a.monthend,'mm/dd/yyyy ') = 31 January 2009"
(et to_char(b.date,'mm/dd/yyyy') = December 31, 2008 "
and b.apr < 20)

problem with join of two tables
Hi, consider the following data
what I want to do, is to join data2 with data by isi, ri or southern id table and produce this output.WITH data AS ( SELECT 123 cid, 'aaa' isi, 'kkk' sud, 'ttt' ri FROM dual UNION ALL SELECT 222 cid, 'bbb' isi, 'gggg' sud, 'hhh' ri FROM dual ) , data2 AS ( SELECT 'aaa' isi, 'yyy' sud, 'ooo' ri FROM dual UNION ALL SELECT 'qqq' isi, 'ggg' sud, 'ooo' ri FROM dual UNION ALL SELECT 'uuu' isi, 'ppp' sud, 'ttt' ri FROM dual UNION ALL SELECT 'ppp' isi, 'mmm' sud, 'nnn' ri FROM dual )
It's how I got the above output:cid txt === ==== 123 aaa 222 ggg 123 ttt
first try to join isi in database2 with isi in "features" and discover if line matches. If this is the case, display the cid of the data table and the use of the value to match.
e.g. in the first line of table data2, we can see that isi = aaa matches line an isi data table. If the output displays 123 and value aaa.
If the rank table two of the Data2 isi = qqq. When join them with the data table, we find not all isi with qqq. in this case, it must join with column of South. We can see that South = ggg data2 games
the second line in the table of output so will bee 222 and value ggg.
now, take a look at the third row in Database2. ISI = uuu is not found in the data table when join them. then try to join to the South. South = ttt is also not found in any row of the data table. so join with ri. We
can see that ri = ttt data2 matches with ri = ttt in the table of data online 1. Therefore, we display the value.
can someone help me write a sql query that joins these two tables by isi. If no line found then join South, if no found rows then join in ri? Thank youHello

Hi Frank, data2.sud = 'Gay' (4 characters) assume to be South = "ggg". by mistake, I type extra g.I have another question about the request. What happens if I want to bring rows of data.2 even if they do not exist in the data table for the entire column was join?
for example, I want to show this:cid txt === ==== 123 aaa 222 ggg 123 ttt ppp --row from data2
the columns of the last row of data.2 does not match any column in the data table. in this case, I want to make but cid will be null. I tried outer join on your request, but it looks like I can not clause or with outer join
SELECT d1.cid , CASE WHEN d1.isi = d2.isi THEN d2.isi WHEN d1.sud = d2.sud THEN d2.sud ELSE d2.ri END AS txt FROM data d1 JOIN data2 d2 ON d1.is(+)i = d2.isi OR d1.sud(+) = d2.sud OR d1.ri(+) = d2.ri ;
How can I re - write the query for this case? Thanks again for your help
Here is the outer join syntax:
SELECT d1.cid , CASE WHEN d1.isi = d2.isi THEN d2.isi WHEN d1.sud = d2.sud THEN d2.sud WHEN d1.ri = d2.ri THEN d2.ri ELSE d2.isi END AS txt FROM data2 d2 LEFT OUTER JOIN data d1 ON d1.isi = d2.isi OR d1.sud = d2.sud OR d1.ri = d2.ri ;
The + sign for outer joins only works with the old join syntax, non-ANSI. Do not try to mix the two different ways to do joins.
Not to mention that the outer join, don't forget to change the CASE expression, to include the new possibility of any columns 3 join matching.

Problems with slot-shaped table and set the values of column
Hello
I have a problem with a tabular presentation.
I have two tables
P_detail and table v_master
columns of v_master:
v_id
v_Name
v_info
columns of p_detail:
P_ID
p_master_fk
p_name
p_info
I want to have a tabular presentation where I can store permanent data retail values. That's why I want to keep the default main column join the detail columns.
In SQL, I can do this with an outer join:
SELECT m.v_name, d.p_master_fk, d.p_name, d.p_info
OF v_master, p_detail
WHERE v_id = p_master_fk (+)
I get the lines that exist for the master data and can add values for the columns of detail. I removed the "add lines" because that makes no sense, because the amount lines are already offered at the opening of the tabular presentation.
Now, I want to get/save the v_id (main table) in the p_master_fk column value
How can I do this?
Thank you and best regards,
MatthiasHello
One approach is to use a database instead trigger. If you define a database view using the query:
SELECT m.v_id, m.v_name, d.p_id, d.p_master_fk, d.p_name, d.p_info
OF v_master m, p_detail d
WHERE v_id = p_master_fk (+)Then, create a trigger on the view that will insert in the detail table if d.p_id is null and update the secondary table if d.p_id is not null instead.
The Apex tabular form is then based on the view (with identifiers like hidden columns) and all treatments multirow Apex should work without modification.

So, today I received my new 9320 at Virgin Mobile, first Blackberry & love the phone! but I can't use the BBM or Facebook app...
At first I could not even access the browser while that connected to my wifi... then I phoned Virgin & they helped me to reset the settings on my BB that I could use the browser etc...
I thought it was problem solved, until I discovered BBM and Facebook, use app world separate service? Anyway, I phoned up to Virgin because I wanted to do this job, they are included in my package & I did not understand why I can't access any of them...
After a long phone call the problem has proved that the "host routing table" was empty and (according to in Virgin) there is a problem with new BlackBerry receiving these details... they said this isn't a problem on the end there & told me there is nothing more they can do so to click 'register now' and wait for the details...
24 hours later and nothing, so I hope someone here can help me, make me a BB the whole point is things miss me actually lol and I feel now I'm paying for a phone contract I can't really use it, without any help from my provider?
Any help?
Or
Anyone with a new BB knows something like that recently? Thank you
Wow... Virgin you gave really there. You see, you PAY for 100% of your services and 100% of your formal support... at the moment, they seem to be or you deliver. Only they have the ability (in fact the RESPONSIBILITY!) to degenerate RIM requiring improved support of cases (from your description, it must be that... with a HRT empty, nothing that anyone here can do). End users have no free path to receive assistance from the RIM at all - only via the escalation. So, what I would do if I were you, is their ring back... but this time do not let you fob OFF... insist that, because you HAVE them, you have a contract with them and they are about to be in violation of this contract - they must solve your problem, degenerate into RIM if they wish.
Good luck!

Problem with a light Table in Bridge CS6
Hello! After a re - install (which does not solve the problem with PS), now, I find that, when you use the light table in Bridge CS6, and after hitting the SPACEBAR, if I then click on the image, it goes to the size of 800%! Before the uninstall and reinstall, it has perfectly worked by taking images at 100% size.
I hope someone can help...
Thanks, farming
Why you reinstall photoshop cs6?
What operating system do you use?
You reinstall all updates Photoshop cs6 by going to help > updates within photoshop cs6?
After you enter the light table, use your mouse wheel to zoom to 100% and leave the light table.
The next time you go to the lightbox and click on the photo, it should only go to 100%.

If there is only a single ID for the IN clause, it works. But if more than one ID is provided, I get an error message "SQL command" not correctly completed. Here's the query as CF:
DELETE FROM TRAINING WHERE userID = <cfqueryparam cfsqltype="CF_SQL_VARCHAR" value="#trim(form.userID)#"> AND TRAINING_ID in <cfqueryparam value="#form.trainingIDs#" cfsqltype="CF_SQL_INTEGER" list="yes">
Someone at - it works with Oracle that can help me with this? I'm a developer experienced in MS - SQL; Oracle is new to me.
Thank you
^_^
So much worse... a colleague just told me I should always use parentheses around the values in the IN clause.

Join several tables of two different patterns - is it possible?
If this is the case, what are the measures?
THXThis is the case.
You must prefix the tables with the schemaname tables is in, or create a synonym for the table. In addition, you must grant select rights from of a the reference schema owner schema:
SELECT A.*,B.* FROM SCHEMA1.TEST_TABLE A, SCHEMA2.TEST_TABLE B WHERE somecondition

Select the problem with joined tables
Hello everyone I have the following query
The problem I have is any WHERE clause I use I have double values that makes no sense. I checked in the tables and I not all double values. Each Opremljenost has 1 objekat (there are 2 rows of each with its own Objekat) and this applies to 2 other tables (PONUDE and TEHNICKE OPREMLJENOSTI), but for some reason any that they double values. If I run it without a where clause at all clause, I get a repetition of values itself up to 4 times. Does anyone have an idea what's wrong with my request?SELECT OBJEKTI.OBJEKAT_ID OBJEKAT_ID, OBJEKTI.ADRESA ADRESA, OBJEKTI.POVRSINA POVRSINA, OBJEKTI.BROJ_IZVRSILACA BROJ_IZVRSILACA, OPREMLJENOSTI.OPREMLJENOST_ID OPREMLJENOST_ID, OPREMLJENOSTI.PULT PULT, OPREMLJENOSTI.REKLAMA REKLAMA, OPREMLJENOSTI.MOKRI_CVOR MOKRI_CVOR, OPREMLJENOSTI.WC_ZA_IGRACE WC_ZA_IGRACE, OPREMLJENOSTI.WC_ZA_OSOBLJE WC_ZA_OSOBLJE, OPREMLJENOSTI.VENTILATOR VENTILATOR, OPREMLJENOSTI.OSVJETLJENJE OSVJETLJENJE, OPREMLJENOSTI.VRSTA_BROJILA VRSTA_BROJILA, OPREMLJENOSTI.ELEKTRO_INSTALACIJE ELEKTRO_INSTALACIJE, OPREMLJENOSTI.VODO_INSTALACIJE VODO_INSTALACIJE, OPREMLJENOSTI.TELEFONSKE_INSTALACIJE TELEFONSKE_INSTALACIJE, OPREMLJENOSTI.GRIJANJE_ID GRIJANJE_ID, OPREMLJENOSTI.POD_ID POD_ID, OPREMLJENOSTI.PROZORI_VRATA_ID PROZORI_VRATA_ID, OPREMLJENOSTI.OBJEKAT_ID OBJEKAT_ID1, TEHNICKE_OPREMLJENOSTI.TEH_OPR_ID TEH_OPR_ID, TEHNICKE_OPREMLJENOSTI.ONLINE_KLADIONICA ONLINE_KLADIONICA, TEHNICKE_OPREMLJENOSTI.PANO PANO, TEHNICKE_OPREMLJENOSTI.NOSACI NOSACI, TEHNICKE_OPREMLJENOSTI.TV_LCD TV_LCD, TEHNICKE_OPREMLJENOSTI.TV_TELETEXT TV_TELETEXT, TEHNICKE_OPREMLJENOSTI.APARATI_IGRE APARATI_IGRE, TEHNICKE_OPREMLJENOSTI.EVONA EVONA, TEHNICKE_OPREMLJENOSTI.NOVOMATIC NOVOMATIC, TEHNICKE_OPREMLJENOSTI.RULET RULET, TEHNICKE_OPREMLJENOSTI.BILIJAR BILIJAR, TEHNICKE_OPREMLJENOSTI.KLIMA KLIMA, TEHNICKE_OPREMLJENOSTI.OBJEKAT_ID OBJEKAT_ID2, PONUDE.PONUDA_ID PONUDA_ID, PONUDE.ONLINE_TERMINAL ONLINE_TERMINAL, PONUDE.SRECKE SRECKE, PONUDE.ONLINE_KLADIONICA ONLINE_KLADIONICA1, PONUDE.APARATI_IGRE APARATI_IGRE1, PONUDE.RULET RULET1, PONUDE.BILIJAR BILIJAR1, PONUDE.OBJEKAT_ID OBJEKAT_ID3 FROM OBJEKTI, OPREMLJENOSTI, TEHNICKE_OPREMLJENOSTI, PONUDE WHERE (PONUDE.OBJEKAT_ID=OBJEKTI.OBJEKAT_ID AND TEHNICKE_OPREMLJENOSTI.OBJEKAT_ID=OPREMLJENOSTI.OBJEKAT_ID) OR (OPREMLJENOSTI.OBJEKAT_ID=OBJEKTI.OBJEKAT_ID AND TEHNICKE_OPREMLJENOSTI.OBJEKAT_ID=OPREMLJENOSTI.OBJEKAT_ID) ORDER BY OBJEKTI.OBJEKAT_ID
Well, if all relationships are to 1-1 (1-0), then try this (the names of table/column, but you get what I mean bad):
select OBJ.*, OPR.*, TEH.*, PON.* -- I know you can't do this, but you get what I mean. from OBJ,OPR,TEH,PON where OBJ.object = OPR.object (+) and OBJ.object = TEH.object (+) and OBJ.object = PON.object (+) /
its supposed to be a 1 to 1 relationship, but it is not.
In this case the remedy is very simple: create a UNIQUE constraint on the column of the OBJECT in OPR, TEH and PON...

joining several tables to generate data
with itemlist as
(select 1 cid, listname 'test', 'r' flg Union double all the)
Select 2 cid, listname 'test2', ' not flg double
),
category 1)
Select 1 cid, 122 k' sub '123' catcode, of any double Union
Select 1 cid, '234i' catcode, sub '124' all Union double
Select 1 cid, 238 k' void '124' catcode, double
)
void)
Select 1 cid, sub '123' of any union double
Select 1 cid, sub ' 124' double
)
I want to write a static query that gathers all the tables and produces the following output assuming that
CID is you pass as a parameter
CID listname flg topic catcode
1 123 122 k r test
1 test of r 234i 124
1 124 238 k r test
Suppose the data as changes to follow and even cid 1 is to pass as a parameter:
with itemlist as
(select 1 cid, listname 'test', 'r' flg Union double all the)
Select 2 cid, listname 'test2', ' not flg double
),
category 1)
Select 1 cid, 122 k' sub '123' catcode, of any double Union
Select 1 cid, '234i' catcode, sub '124' all Union double
Select 1 cid, 238 k' void '124' catcode, double
)
void)
Select 2 cid, sub '123' of any union double
Select 2 cid, sub '124' double
)
then the output should be
CID listname flg topic catcode
1 r test 123
1 test of r 124
1 test of r 124
for a final example, suppose the data now as to user 1 as cid
with itemlist as
(select 1 cid, listname 'test', 'r' flg Union double all the)
Select 2 cid, listname 'test2', ' not flg double
),
category 1)
Select 2 cid, 122 k' sub '123' catcode, of any double Union
Select 2 cid, catcode '234i', '124' void in any union double
Select 2 cid, 238 k' void '124' catcode, double
)
void)
Select 1 cid, sub '123' of any union double
Select 2 cid, sub '124' double
)
output must be
CID listname flg topic catcode
1 test r 123
Basically, the user will pass a cid, in this case 1. I'll read the itemlist where cid = 1 and I want to join all the other tables
to itemlist in such a way that I can generate extra lines. If no entry is found for cid 1, for example, in category 1 or auxiliary table
then the beloging column of this table must be null in the result
can someone help me write a query to produce the output above
Hello
elmasduro wrote:
...
Here is an explanation of the output. a user will have a front screen where it can enter itemlist info.
then in a submenu may enter a category or sub or both or none of them. the user can select multiple categories or sub
When the user presses the button Save, an entry will be made in the itemlist table, for example the cid = 1.
If he choose a category but without Subs, then will be entered into the table at say cid = 1
but no entries will be made for sub because he chose not to all values. If he chooses void instead of category values
then sub taable will fill and category is not. If he chooses the category and under, then both will be filled.what I want to do is to join the itemlist with table category and sub table and get the data to the Scriptures, this intervention of the user.
These entries not found will be the null value column in the result.
for example, the cid = 1 itemlist, if user enter category but not void, itemlist will be the join with the table category and sub
but since sub has no entry for the cid = 1, the column object will be empty in the output, but catcode will fillI'm so confused.
It is a query (that is, just a SELECT statement, which shows the data already present in the tables), or is this a DML statement, that will add data to the tables? If it's just a query, then do not say things like "entries will be taken" or "filled with tables.
Assuming you want a request maybe you want something like this:
WITH c_and_s AS
(
SELECT NVL (c.cid, s.cid) AS cid
NVL (c.sub, s.sub) AS topic
, NVL2 (s.cid, c.catcode, NULL) AS catcode
CATEGORY 1 c
FULL OUTER JOIN void s ON c.cid = s.cid
AND c.sub = s.sub
)
SELECT i.cid, i.listname, i.flg
cs.subject, cs.catcode
Itemlist I have
LEFT OUTER JOIN c_and_s ON cs.cid = i.cid cs
WHERE the i.cid (1) - you can do the cids 2 or several at the same time, if you want to
ORDER BY i.cid, cs.subject, cs.catcode
;
This example gets the output you asked data sample you posted.

Problem with populating a table of facts, of dimension tables
My goal is there are 5 dimensional tables created
Student-> primary key s_id, upn(unique pupil no), name
Rank-> key primary g_id, grade, exam_level, values
Object-> key primary sb_id, subjectid, subname
School-> key primary sc_id, schoolno, school_name
year-> y_id primary key, year (like 2008)
S_ID g_id sb_id, sc_id, y_id are sequences
select * from student; S_ID UPN FNAME COMMONNAME GENDER DOB ============================== 9062 1027 MELISSA ANNE f 13-OCT-81 ... 9000 rows selected
It's basically the dimensional point of viewselect * from grade; G_ID GRADE E_LEVEL VALUE ---------- ---------- ---------- ---------- 73 A a 120 74 B a 100 75 C a 80 76 D a 60 77 E a 40 78 F a 20 79 U a 0 80 X a 0 ... 18 rows selected
According to the given specifications, now need to create a table of facts like facts_table that contains all the primary keys of tables IMG as foreign keys in it.
The problem is when I say, I'll look at an example of smaller that the reality of dimension tables 5 let say there are 2 student dim tables, rank with s_id, g_id as the p key.
The result is a massive duplication as there is no join between two tables. But basically there is no common things between the two tables to join, how to solve?create materialized view facts_table(s_id,g_id) as select s.s_id,g.g_id from (select distinct s_id from student)s , (select distinct g_id from grade)g
Think of it as when I do for 5 tables the amount of duplication being involved, why there is not enough tablespace.
I was hoping that if there is no other way then don't create a fact table with just a column at the start
thencreate materialized view facts_table(s_id) as select s_id from student;
Then fill this column g_id fetching all the grade table g_id values using some sort of loop, although we shouldn't use pl/sql, I don't know if it works?alter materialized view facts_table add column g_id number;
All of the suggestions.TROPPER,
Your information, I have tried this test see if it works for you

problem with learning several geometric pattern
Hello users of Labview,.
My goal is to load different templates located in the target folder, create one or more models then, perfom some treatment (located in another file) image.
The example provide in file vision works perfectly but if I change the path, it seems impossible to create a multiple repeat. In fact, I got the following error message:Error 1074395628 has occurred to IMAQ learn several geometric patterns
IMAQ Vision: Image model corresponding invalid geometry.
Certainly, I do not understand a part but I don't know where is my mistake.
I add to the multiple associated model, an example of template image and the image to test.
Please, can I have a help or suggestion to understand this problem.
Thanks in advance for your help,
Best regards
Hi matriax,.
Good to know it helped.
Come to your questions,
-Yes, model geometric information, or even in vision assistant also will not work.
-In my code too, it does not work. The reason is explained below.
-Yes, model created with assistatn vision should also work.
Coming to the creation of a model, there are two geometric methods correspondent-function based and based edge.
-Labview code uses geometric based function while u have created the model in edge based method.
-If you see in vision assistant, settings tab, you have the type of algorithm two options. Select the base feature and you should be able to run it and then assistant labview and vision.
For more details on geometric matching please refer to http://zone.ni.com/reference/en-XX/help/372916L-01/nivisionconcepts/geometric_matching_technique/
Hope that helps let me know if you have any other questions.
