combining two tables
Hello
I have a while loop that runs trough each case in a box structure. Each of these cases produced a 1 d table. How can I combine these tables in a 2d array. An attempt with two cases is attempted in the attached diagram.
The problem is it seems to fill the first column with zeroes when you add the second row in table
Hi Jagwa,
first: use a registry to offset instead of tunnels. In this way, the result of the first iteration is not lost in the 2nd
"It seems to fill the first column with zeroes" - no, just the table of origin once again, but now by replacing the second row!
2nd:
When your loop runs twice, all the time why not use a FOR loop instead? No need to check for "I".<>

Combine two tables 1 d in a 2D array
Hi all
Maybe I forget what is obvious, but I can't find a solution to combine two tables 1 d in a 2D array AND (it is the impossible part for me) using the tables columns instead of lines.
Example:
Table 1:1, 2, 3, 4
Table 2:5, 6, 7, 8
Result: 1, 5
2, 6
3, 7
4, 8
The 'build array' function seems to add all tables as lines... I guess I could transpose the table, but I want it runs in a Subvi in constructions of different loop and I feel a little uncomfortable with it - I guess one would be left with a completely mixed table. I was maybe blind just to find the right function?
Cheers, Jessi
Hi Jessi,
by default, LV is combining tables in rows. So when you need columns you must transpose the sets or use a different indexing scheme...

Combine two tables using Actionscript Flex Applications errors
Hello
I have a set of Actionscript code below that I would run based on a query and have it display what are all of the selections that I posted from the checkbox elements two repeater.
This doesn't seem to work every time when I get to the checkBox_change2 function. I still see some error messages popping up telling me that I have references null to that particular line: var selArr3:Array = selArr2.concat (selArr);
Could someone tell me how I can get checkBox_change2() don't forget the selections, I did in checkBox_change()? I tried to use public var for the [Bindable] above but I still get the same error.
Thanks in advance.
AliceYou are declaring your selArr not always correctly.
The statement [Bindable] private var selArr:Array; is an instance variable. It is defined outside of any function and is visible from almost anything in your object.In your service
private void checkBox_change(evt:Event,x:Array):void {}
selArr:Array = [];selArr is defined as a local variable that is visible only in the function checkBox_change. Because the names are the same that you override the instance variable. (In reality this is not compiling correctly... your first try for var selArr:Array = [] was the valid syntax for the variable substitution)
To remedy this, you just need to change
selArr:Array = [] in selArr = []; -
combine two daq physical channels in a single task
Hi all!
I use a PCI-6120 with a BNC-2120 to generate two signals: one is used to control an optical device which must be characterized, and the other signal is sent to a digital video camera to trigger the acquisition so that it is synchronized with the first signal. Everything is controlled with Labview.
I want to give the possibility to the user to choose which channel to use for the first signal and channel to use for the second signal, depending on how the devices connected to the BNC-2120. So I would like to put two different "physical channel" screws on the Labview command window.
My question is:
What I need to create two different tasks to the signals to be generated on the appropriate channel, or can I combine two channels (and how?) think I handle only a single task to two channels always but do not forget that each signal is generated on the corerct channel, depending on the channel selected for each of the two signals...?
Thanks a lot for your answers.
Nice day.
Luke
Hi LucG,
If you use only a single Council to create only a single task for two generations.
You can choose several channels by clicking on "Restaurants" in the channel control physical choice multiple channels thanks ctr + click, or by concatenating multiple channels with a comma as on arrival at the VI.
Then, when you provide data to the VI of writing, the data should be organized in a table, each channel is on a line and the order of the channels is the same as in the control of the physical channels.
I hope this can help!
Thank you

Left join of the two tables and multiple values into a single value separated by commas
Hello
I have following tables with their structures and their data as below.
CREATE TABLE 'BETODI '. "" BETINFO ".
(
VARCHAR2 (8 BYTE) "CURRENTPRESS."
ENABLE 'TYPEIDCONTAINER' VARCHAR2 (30 BYTE) NOT NULL
)
INSERT INTO Betinfo (Currentpress, typeidcontainer) VALUES ('A24G', 'PMC');
INSERT INTO Betinfo (Currentpress, typeidcontainer) VALUES ('A24D', 'Pensky-MARTENS');
INSERT INTO Betinfo (Currentpress, typeidcontainer) VALUES ("A25D", "CMP");
INSERT INTO Betinfo (Currentpress, typeidcontainer) VALUES ('A25G', 'PMC');
INSERT INTO Betinfo (Currentpress, typeidcontainer) VALUES ('A26D', 'PMC');
INSERT INTO Betinfo (Currentpress, typeidcontainer) VALUES ('A26G', 'PMC');
INSERT INTO Betinfo (Currentpress, typeidcontainer) VALUES ("A32G", "V-BFC3");
INSERT INTO Betinfo (Currentpress, typeidcontainer) VALUES ('A32D', "V-BFC2");
CREATE TABLE 'BETODI '. "" BETMASTER ".
(
ACTIVATE THE "CUREPRESS" TANK (5 BYTES) NOT NULL,
ACTIVATE THE "TYPE" VARCHAR2 (5 BYTE) NOT NULL,
NUMBER (5.0) "LASTPCIRIM".
)
INSERT INTO BetMaster (Curepress, type, lastpcirim) VALUES ('A24', '45 M 8', 15);
INSERT INTO BetMaster (Curepress, type, lastpcirim) VALUES ('A25', 42 16', 15);
INSERT INTO BetMaster (Curepress, type, lastpcirim) VALUES ("A26", 16' 45, 15);
INSERT INTO BetMaster (Curepress, type, lastpcirim) VALUES ("A27", '45 M 34', 16);
INSERT INTO BetMaster (Curepress, type, lastpcirim) VALUES ('A28', '45 M 34', 16);
INSERT INTO BetMaster (Curepress, type, lastpcirim) VALUES ('A29', '45 M 34', 16);

INSERT INTO BetMaster (Curepress, type, lastpcirim) VALUES ('A33', '45MCH', 16);
INSERT INTO BetMaster (Curepress, type, lastpcirim) VALUES ("A34", "45MCH", 16);
These two tables have left join as
BETMASTER. CUREPRESS = substr (BETINFO. CURRENTPRESS, 1, 3)
now I want to have the data in the two tables with fields Curepress, Lastpcirim, typeidcontainer.
Also something like
Make a group of typeidcontainer if this value is greater than 1 by press separated the values of semicolon (;)
So, for example above, we should be given as
A24 PMC 15; PENSKY-MARTENS
A25 15 PMC
A26 15 PMC
A27 16 (NULL)
A28 16 (NULL)
A30 15 (NULL)
A31 16 (NULL)
A32 16 BFC2-V; V BFC3
A33 16 (NULL)
A34 16 (NULL)
How could do?
My current request is as
Select distinct Curepress, lastpcirim, typeidcontainer
BETMASTER STD left join INF BETINFO
on the trim (STD. CUREPRESS) = substr (trim (INF. CURRENTPRESS), 1, 3)
but I am unable to get the values separated by commas.
Any help would be appreciated.
Thank you
Mahesh.
Hi, Mahesh,
If you want to only 1 row of output for each distinct combination of currentpress and lastpcirim? This sounds like a job for GROUP BY.
And you want the row to contain a list of all different typidcontainers-delimited? This sounds like a job for the aggregate LISTAGG function.
WITH joined_data AS
(
SELECT DISTINCT
MST.curepress, mst.lastpcirim, inf.typeidcontainer
OF betmaster STD
LEFT JOIN betinfo ON TRIM (mst.curepress) inf = SUBSTR (TRIM (inf.currentpress)
1
3
)
)
SELECT curepress, lastpcirim
LISTAGG (typeidcontainer, ',')
THE Group (ORDER BY typeidcontainer) AS container_list
OF joined_data
Curepress GROUP, lastpcirim
;
Unfortunately, you can't say LISTAGG (DISTINCT ...), so you should always get the separate containers how you already are. (Note that the subquery is just what you posted).
Thanks for posting the CREATE TABLE and INSERT statements; It is very useful. Don't forget to tell what version of Oracle you are using. LISTAGG was new in Oracle 11.2.
Why not add CHECK constraints (and perhaps triggers) to your tables, so that curepress and currentpress are not stored with the head or trailing spaces? Then you wouldn't need to use the PAD in queries like this, and your code would be simpler and more effective.

Hello
I need your help in the script below:
I have two tables.
My "table1" table contains the data below:
Code:
Name, Value
------------
12 A, 1
12 B, 1
12 C, 1
Table2 contains the following data:
Code:
value, result
------------
1.12
1.24
1.56
1 423
1.32
1, 3
I need to join based on a field value.
My result is:
Code:
NAME, VALUE, RESULT
-------------------------
12 A, 1, 12
12 B, 1: 24
12 C, 1, 56
12d, 1, 423
12TH, 1, 32
12F, 1, 3
Based on the number of records in the second table, it must add A to Z at the end of the name field. The number of records exceeds no more than 26. How can we achieve this?

Thank you
PocardOK, now you give other useful information - that there always will be combinations of amounts in table2 to match values in table1. (It is difficult to help when you say the specs one both :-))
But it is not easy, because the code should really try to consider all combinations and then 'choose the right' - it's easy for us humans, but not easy to code in the programming logic.
I made an attempt:SQL> set linesize 120 SQL> with table1 as ( 2 select 'A1' name, 123 id, 150 value from dual union all 3 select 'A2' name, 123 id, 200 value from dual union all 4 select 'A3' name, 123 id, 300 value from dual 5 ), table2 as ( 6 select 123 id, 100 value from dual union all 7 select 123 id, 100 value from dual union all 8 select 123 id, 50 value from dual union all 9 select 123 id, 100 value from dual union all 10 select 123 id, 100 value from dual union all 11 select 123 id, 100 value from dual union all 12 select 123 id, 100 value from dual 13 ) 14 -- 15 -- End of test data 16 -- 17 select 18 t1.id, t1.name, t1.value, t2.value, 19 t1.rn, t1.minval, t1.maxval, 20 t2.rn, t2.sumval 21 from ( 22 select 23 tab1.*, 24 nvl(sum(tab1.value) over ( 25 partition by tab1.id 26 order by tab1.rn 27 rows between unbounded preceding and 1 preceding 28 ),0) minval, 29 sum(tab1.value) over ( 30 partition by tab1.id 31 order by tab1.rn 32 rows between unbounded preceding and current row 33 ) maxval 34 from ( 35 select 36 table1.*, 37 row_number() over ( 38 partition by table1.id 39 order by table1.value desc 40 ) rn 41 from table1 42 ) tab1 43 ) t1 44 join ( 45 select 46 tab2.*, 47 sum(tab2.value) over ( 48 partition by tab2.id 49 order by tab2.rn 50 ) sumval 51 from ( 52 select 53 table2.*, 54 row_number() over ( 55 partition by table2.id 56 order by table2.value desc 57 ) rn 58 from table2 59 ) tab2 60 ) t2 61 on (t2.id = t1.id) 62 where t2.sumval > t1.minval 63 and t2.sumval <= t1.maxval 64 order by 65 t1.id, 66 t1.rn, 67 t2.rn 68 ; ID NA VALUE VALUE RN MINVAL MAXVAL RN SUMVAL ---------- -- ---------- ---------- ---------- ---------- ---------- ---------- ---------- 123 A3 300 100 1 0 300 1 100 123 A3 300 100 1 0 300 2 200 123 A3 300 100 1 0 300 3 300 123 A2 200 100 2 300 500 4 400 123 A2 200 100 2 300 500 5 500 123 A1 150 100 3 500 650 6 600 123 A1 150 50 3 500 650 7 650 7 rows selected.
It doesn't seem to work for your sample data, but it is much too simple a rule at work in general. My "rule" is simply of sorts data according to the value descending and adding up to what 'enough' of values have been added.
Consider this example of data instead of this:

In this data set simple ranking by value won't work - it should have been A3: (225,75), A2: (175,25) and A1: (50.50).
I can't really think of a reasonably easy way to do this in SQL only. Maybe using the clause TYPE would be possible, but not negligible. It is possible, it would be easier to solve this problem in PL/SQL in iterating through a few tables and intelligently to try different combinations, rather than creating all combinations in a huge piece of brute force SQL.
I'm sorry, Pandeesh, but I can't think a solution easily.
I might be able to do something, if I fiddled with the problem for a few days, but that would be beyond the scope of this forum. It would be a consultation of employment rather than a little help from the forum :-) -
Immagerie two tables without a CARPENTER
Hello
I had a little problem. I want to combine the two tables. But I don't need a Carpenter, cause that would give me wrong combined values.
I have a table working_hours which has the actual hours of work of employees. And a table times_absent that the absent employee time.
The two tables have the date and hours actual work and absent in addition to other tings inside.
Simple I want to combine these two tables in a large table.
Example:
Table working_hours:
Name - Date - hours-...
Mr.A - 2.5.2011 - 8-...
Mr.B - 2.5.2011 - 6-...
C 2.5.2011 - 7-...
Table times_absent:
Name - Date - day-...
Mr.A - 3.5.2011 - 1-...
Mr.B - 3.5.2011 - 2-...
Mr.B - 4.5.2011 - 2-...
New Table:
Name - Date - Working_Hours - Absent_Days-
Mr.A - 2.5.2011 - 8 - null - or some sort of dummy value XXX
Mr.A - 3.5.2011 - null-- 1
Mr.B - 2.5.2011 - 6 - null.
Mr.B - 3.5.2011 - null - 2-
Mr.B - 4.5.2011 - null - 2-
and so we.
Is there a possibility in the OWB to perform this task?
THXI did not understand your answer, but the OPERATOR PUT a couple IN a GROUP. What you need to do is connect your table 1 to table 2 for INgroup2 and INgroup1 (the two tables must have the same number and type of columns and the order is also important) and set your SET UNION operator, and that's all.

I like the result to look like who has a few conditions such as -
1 - the records in the table Football are high vs Baseball table because there is no condition to filter the records of the Football.
2 - football is a superset of records and Baseball is a subset.
3 - COMPENSATION NOM_JEU and RUNNING NOM_JEU may return the same values as well.
I want the result to be in the following form-
EXECUTION ID GAME | NAME OF THE GAME TO RUN. COMPENSATION ID GAME | DELETE THE NAME OF THE GAME.

How to join two tables of different schemas of Oracle by using a subquery
I'm trying to join two different schemas of Oracle tables using a subquery. I can extract data from each of the tables without problem. However, when I combine select statements it by using a subquery I get Oracle error *'ORA-00936: lack of expression ' *. Given that each SELECT statement runs on its own without error I don't understand what's missing. I'm trying to get the result set is matching the LINE_ID of PDTABLE_12_1 in the schema with the table PDTABLE_201 MAT_DESCRIPTION DD_12809 in the RA_12809 schema.
The query is as follows:
SQL = "SELECT [DD_12809]. [PDTABLE_12_1]. LINE_ID OF [DD_12809]. [PDTABLE_12_1] JOIN "_".
+ "(SELECT [RA_12809]. [PDTABLE_201]. MAT_DESCRIPTION "_".
"FROM [RA_12809]. [PDTABLE_201]) AS FAB "_".
+ 'ON [DD_12809]. [PDTABLE_12_1]. PIPING_MATER_CLASS = FAB. PIPING_MATER_CLASS ".
The format of the request is copied from a manual of programming SQL.
I also tried running the query uses a right JOIN on the two tables, but got the same results. Any ideas would be useful. Thank you!
Published by: user11338343 on October 19, 2009 06:55The format for the join of two tables in Oracle feels like any other database:
SELECT a.col1, a.col2, ..., b.col1, b.col2, ... FROM schema1.table1 a, JOIN schema2.table2 b ON a.col = b.col and ... WHERE a.other_col = 'FRED' AND ....;
Do not place bracketed identifiers in Oracle. The account that connects to the database must have select privileges on the two tables.

How to make an update of a view online two tables...
When the unique constraint of the second table includes three columns?
I have two tables A and B and I want to update a table column, one using an update of a view online two tables.
Table A:
col1 primary key
col2
Table B:
col1 u1
col2 u2
COL3 u3
COL4
col5
Table col1 primary key, table B has a unique constraint on col1, col2 and col3.
Tables A and B are joined in this way:
And now, I want to update this view and set KEY_OLD = KEY_NEW.select A.col1, A.col2 as KEY_OLD, B.col5 as KEY_NEW from A, B where (B.col1 = 'literal_1') and (B.col2 = 'literal_2') and (A.col1 = B.col3) and (A.col2 = B.col4)
Because of the first three conditions in the where clause for each entry in the table A there is just a matching entry in the table B.
So the table should be preserved in the join key.
But during the update
I get an error ORA-01779.update (select A.col1, A.col2 as KEY_OLD, B.col5 as KEY_NEW from A, B where (B.col1 = 'literal_1') and (B.col2 = 'literal_2') and (A.col1 = B.col3) and (A.col2 = B.col4) ) set KEY_OLD = KEY_NEW;
I did the updates on inline views this way several times in recent weeks and it work very well.
But so far the unique constraint on the table B was just a column ;-)
