Join the tables of towing on the overlap of the keywords.

I must join two large tables and have the situation like this:

TABLE_1		TABLE_2
Ibis	<>-	Ibis Sydney Airport
the Ibis budget	<>-	Ibis budget Enfield
Ibis Styles	<>-	Hotel Port Hedland

And avoid the situation like this:

TABLE_1		TABLE_2
Ibis	NO.	Ibis budget Enfield
Ibis	NO.	Hotel Port Hedland

Is it possible using SQL/PLSQL?

The solution is strongly dependent on the structur of your data.

A simpe approach can be:

with t1 as)
Select'ibis all of the double union
the select 'ibis' Union budget double all the
Select'ibis Styles of double
)
t2 as)
Select 'ibis Sydney Airport' t of all the double union
' select'ibis budget Enfield "of all the double union
' select'ibis Styles Port Hedland "double
)

Select t, s of)
Select
s
t
, row_number() over (partition by order of t by length (regexp_replace (t, ' ^': s l)))
from t1
t2
where
length (regexp_replace (t, ' ^': s))< length="">
)
where
l = 1
order of s

T, S

"ibis Sydney Airport", "ibis".

"ibis Styles Port Hedland", "ibis Styles.

"ibis budget Enfield", "ibis budget."

If regexp will not run, you can relax the requirement that the match should start at the beginning and replace rege_replace by just replace.

Hi guys,.

I have two tables

Agents and Agent phones but in the agent phones table for the id of an agent it displays 4 rows because one of the column there types of different phones (office, mobile, home, fax)

So instead of display 4 rows, I used max(case...) to convert rows to columns

now how to reach it with another table

Requirement:

This is so the data we have in both table

Now, I transposed rows to columns in the table of agent phones so I used the following query

SELECT AP. AGENT_ID,. AGENT_TYPE_CODE,. AGENT_TYPE_PREFIX.

MAX (CASE WHEN AP. PHONE_TYPE_CODE = 'CELL' THEN AP. PHONE_NUMBER END) AS CELL.

MAX (CASE WHEN AP. PHONE_TYPE_CODE = 'OFF' THEN AP PHONE_NUMBER END) AS TURNED OFF.

MAX (CASE WHEN AP. PHONE_TYPE_CODE = 'FAX' THEN AP. PHONE_NUMBER END) LIKE FAX,.

MAX (CASE WHEN PHONE_TYPE_CODE = 'PHONE'. THEN AP PHONE_NUMBER END) AS PHONE

AGENT_PHONE AP

WHERE AP. AGENT_ID = 29709

GROUP OF AP. AGENT_ID, AP. AGENT_TYPE_CODE, AP. AGENT_TYPE_PREFIX.

My question is how this to join the agents table so that my output should be like this...

I want to display all the results in the table of the Agent, even if they are not in the table of agent phones. As you can see there are other agent id 1234 is also populated

You can rotate your phone number of agent in columns

Select *.

of AGENT_PHONE

pivot)

min (PHONE_NUMBER)

for PHONE_TYPE_CODE in ('CELL' as a 'CELL', 'PHONE' like 'PHONE', 'OFF' in the 'OFF', 'FAX' as 'FAX')

)

29709	RE	OFFICE	4805551436	1111111111	2223334444	5556667788

Then you can join to view inline or CTE

with AGENT_PHONE_PIVOT like)

Select *.

of AGENT_PHONE

pivot)

min (PHONE_NUMBER)

for PHONE_TYPE_CODE in ('CELL' as a 'CELL', 'PHONE' like 'PHONE', 'OFF' in the 'OFF', 'FAX' as 'FAX')

Hi Vincent,.

I think that you have not worked on adf 12.1.3. In adf 12.1.3 you don't have to explicitly create the association. When you create the EO to your table, Association xxxxFkAssoc, will be created by ADF12.1.3 for you automatically. Please try this and do not answer anything... You can also follow the links below. I solved the problem by using the following link

JOIN the question... Join two tables without omitting lines

I came across a problem that should be an easy fix (I hope), but I'm having a hard time to come up with a solution.

Basically I have two tables, one with the actual amounts with the budget. I have to write a sql statement select that joins these tables together and includes all of their lines. I was able to join the tables by using JOIN, LEFT JOIN and RIGHT JOIN, but it always fails the lines I need.

Below, I have examples of my tables (AMOUNT_TABLE and BUDGET_TABLE). For simplicity, I built the examples to show the same values in the first four columns, with the 5th and 6th columns (SUB_ACCOUNT, AMOUNT, BUDGET) as the only values that are different. My actual tables are not quite that simple, but I don't think it was relavent to this issue.

AMOUNT_TABLE

FISCAL_YEAR	PERIOD	ACCT_UNIT	ACCOUNT	SUB_ACCOUNT	AMOUNT
2013

111111555555000010020131111115555551000100201311111155555520001002013111111555555300010020131111115555554000100

BUDGET_TABLE

FISCAL_YEAR	PERIOD	ACCT_UNIT	ACCOUNT	SUB_ACCOUNT	BUDGET
2013

1111115555553000200201311111155555540002002013111111555555500020020131111115555556000200

Here's what I hope. Note that SUB_ACCOUNTs 0000, 1000, and 2000 show without budget amounts since there is not a corresponding line in the BUDGET_TABLE. And same for SUB_ACCOUNTs 5000 and 6000, they show budgets with no amount because there is not a corresponding line in the AMOUNT_TABLE.

(exit)

FISCAL_YEAR	PERIOD	ACCT_UNIT	ACCOUNT	SUB_ACCOUNT	AMOUNT	BUDGET
2013	1	11111	555555	0000	100	0
2013	1	11111	555555	1000	100	0
2013	1	11111	555555	2000	100	0
2013	1	11111	555555	3000	100	200
2013	1	11111	555555	4000	100	200
2013	1	11111	555555	5000	0	200
2013	1	11111	555555	6000	0	200

If all goes well, my question is clear. Any help on this would be greatly appreciated. Thanks in advance.

Use the join ANSI - FULL OUTER JOIN syntax:

Select double 2013,1,11111,555555,4000,100

budget_table like)

Join the tables in the responses
I would like to know if it is possible to join the tables together as below in the answers?

Select a.Field1, b.Field1
FROM tableA an outer join left tableA b on
a.Field1 = b.Field
If you want to make an INNER JOIN, and then type INNER JOIN instead of LEFT INNER JOIN.

If you want to left outer join and LEFT OUTER JOIN instead of INTERNAL LEFT JOIN type.

Nothing asked as a left inner join. That is why it gives error + [nQSError: 27002] near +.

So he needs to MERGE between DEPARTMENTS (that has been sorted by index) JOIN and (here's the part confusing...) LOCATIONS including oracle used HASH JOIN (?) to bring the information from and then sort the opinion generated by the system that has been created...?

Is that this HASH JOIN to step 7 only refers to a view that is generated by the system that oracle had to sort and not actually HASH JOIN
between two tables?

Thanks much for you patience

Hello

Perhaps, it helps to understand things better if we walk in the plan.

Plans have a hierarchical structure (which is translated graphically by fingerprints). Operating needs parent all the children completed operations before it can do its job (which is generally combining lines with children in one way or another).

Another point is that joins can have anything like their entries, tables not only. That is a hash join can join an index for an index or a table to an index, or then to join a table results of hash one another and so on and so forth.

With this in mind, we can go back on what is happening here step by step:

The needs of the join by hash (1) (2) and (10) to finish. (10) is a basic operation, since a table scan depends on nothing else, but merge join handset (2) (3) and (5), who both are complex operations (i.e. dependent on one or more children). Specifically, lines (3) from the DEPARTMENTS table using ROWID obtained from a full analysis of the index of DEPT_LOCATION_IX (4), (5) is simply lines join hash (7) and sorted in the order required.

I hope this helps.

Best regards
Nikolai

The ANSI syntax for the join 4 tables-is this correct?
Hi, I'm new to these forums and I have looked everywhere and cannot find the syntax and examples on how to join the tables 2 and 3 using the ANSI standard, but I need to reach 4. For a traditional join, it would be:

SELECT a.two b.one, b.three, b, a.one, d.seven
Tablea, tableb b, c in tablec, deposited d
WHERE a.one = b.one
AND a.two = c.two
AND c.six = d.six;

Here are the tables:

TableB
one
three
four

TableA
one
two

TableC
two
six

deposited
six
seven
eight

Anyone know how to do this by using an ANSI join or have all of the resources that can guide me in the right direction. I don't know if I wanted to join three tables, it would be:

SELECT a.two b.one, b.three, b, a.one, c.six
FROM tableb b JOIN tablea one WE b.one = a.one JOIN tablec c ON a.two = c.two;

so join a fourth would:

SELECT a.two b.one, b.three, b, a.one, d.seven
FROM tableb b JOIN tablea one WE b.one = a.one JOIN tablec c ON a.two = d JOIN filed c.two ON c.six = d.six;?

Is the above correct or is there another way to do this, use an ANSI join?

Hello

your JOIN looks good,

"FROM tableb b JOIN tablea one WE b.one = a.one JOIN tablec c ON a.two = d JOIN filed c.two ON c.six = d.six" you get a different result set?

Thank you

[Help] Join the query from 3 tables
Hi, I'm new to database. I have a question about joining 3 tables, forgive me for my bad English.

My paintings look like this

Table 1: person (id, firstname, lastname)
Table 2: AssignPersonAddress (id, personid, addressid, type)
Table 3: address (id, phone, street, etc.)

I need AssignPersonAddress table, because in my data structure, a person may have more than 1 address and address type must be registered (for example: private, work)

I want to do a select query to the State any person with his private phone and work phone, like this.
NOBODY | PRIVATE | WORK

Right now my query looks like this
```
select p.name , a1.tel AS Private, a2.tel AS Work
from person p, 
addresse a1 , 
AssignPersonAddress apd1, 
AssignPersonAddress  apd2, 
addresse a2

where p.id  = apd1.person (+)
and apd1.adresse  = a1.id 
and apd1.art = 'Private' 
and p.objectid = apd2.person (+)
and apd2.adresse  = a2.id 
and apd2.art = 'Work'
```
the problem is that I only get the person who has a private address and the job. But what I want is all anyone no matter if the person has only 1 or 2 address.

As you can see I put the left outer join in where condition, but I always get the wrong result.

THX in advance

Danny

Join the table orders from clause
Hi all

Who is the effective way to join the tables in from clause. I have two tables first with 20 lakh records and second containing 10 lakh recods.
```
 
QUERY 1:  SELECT T4.ID,T4.ISO_NAME  FROM T,T4 
WHERE T4.ISO_NAME LIKE '%US%' AND T.ID=T4.ID;

QUERY 2:  SELECT T4.ID,T4.ISO_NAME  FROM T4,T 
WHERE T4.ID=T.ID AND  T4.ISO_NAME LIKE '%US%';

T(ID IS PRIMARY KEY) 
(20 lakh records)

T4 (ID IS PRIMARY KEY ) 
(10 lakh records)
---------------------
ID     ISO_NAME
100  US,UK,IN,BR
101  UK,US,BR,IN
102  BR,UK,US,IN


Note: No index on ISO_NAME .
```
Who is the effective query 1 or 2. Please suggest me if you have an idea to rewrite the query.

Kind regards
Rajasekhar

In practical terms, Alex is right. Sometimes it matter what table is selected first, but does the CBO generally a very good job of deciding what you need to select the first (assuming that your statistics are up to date) but this is the situation you are trying to avoid as much as possible.

If you specify a table main command tables in the clause is not reliable and should be used - but think before using advice and don't do that when necessary.

Which table to select depends firstly on the join method in the execution plan. Nested loops joins perform better by selecting in the smaller table first, make a loop on the largest table. Joins the smaller set hash table in memory first, and then go through the larger table, perform searches in memory. He can't make any difference, what table is read using first the merger joins and sort.

Back to your original question. Using the cost-based optimizer, both queries will probably roll the same because newer versions of Oracle (9i, 10g) often transform queries for efficiency before the execution anyway. According to what do you or do not request should probably run a nested loop or hash join. With a small set of data creaing index and using a search of nested loops will probably be faster to avoid full table scans. the '%' in the LIKE clause leader would ignore an index on the ISO_NAME column in any case if a main column may be used in a composite index. All this is based on the approximation using the information provided; Tuning questions should always be tested to unexpected developments.

Unable to join the homegroup on new Inspiron 15 5559

I had a residential group put in place for a good while on 3 computers desktop and an old Tower, but my new laptop Dell Inspiron 15 5559 with 10 Windows fails to reach. I get to the point of putting in the right password and clicking NEXT, then the bar keeps of moving from left to right for several minutes, then stops without any messages and not to join.

Here are the details. Computer of One Office (a Dell Inspiron 630 with Windows 7 Pro), a former HP with Windows Pro 10 office, an old house built office with Windows 10 Pro (64-bit), and an old Toshiba laptop with 64 bit Windows 7 Home. All these joined the homegroup very well. In addition to the homegroup, I have the file & printer sharing power with 4 of them. On the Dell desktop computer, I have 9 folders and two shared printers. The new laptop Dell can access shared folders, it is just unable to join the homegroup. I created the homegroup because I had problems to access 2 shared printers (a Canon IP1600 inkjet and laser Samsung ML-2525) with 10 windows, in case you're wondering why I'm not just with the file & printer sharing instead of homegroup.

In any case the key is that everything on this new Dell laptop works fine except that I can not join the homegroup, and I'm very curious as to why not. I did full virus scans with Defender and Norton 360 and have done two scans with MalwareBytes, but no malware has been found. I also ran "SFC/scannow" and it found no problem either. I checked to make sure that I put in the security key for the homegroup, and at this point, I am triple ideas. It please does not restore to the factory settings, because I had this problem since the first day that I got this laptop out of the box before I did any customization. FWIW, I'm no novice in computer science.

What suggest you? TIA

Yesterday I posted a note that I would have found and solved the problem. I don't know what happened to this post. The problem was that there was a popup that was actually a pop-under hidden behind a number of open windows. He said that there was an invalid password. Of course the note that I had used to set up 4 PCs had a "n" where there is now a "m". I would like to say that this has changed from n to m somehow otherwise I don't know how I was able to put in place the other 4 PCs. Anyhoo, the problem is now resolved.

Join the results of a case statement

Hello everyone;
I can't with a query where I use a case statement to create a new column and attempt to reach an additional table on the resulting column. I am fairly new to this and learn by trial and error, so if you think that it looks a little ugly or ineffective, I won't be offended. It is used on my interface based on the web of companies, while I am not able to answer some basic questions such as the version of db.
My need to use the case statement is the result of some strange methods and somewhat contradictory in order to link the product subcodes (sku, fcsku, fnsku), to a product code parent (ProdID). In this case, the inventory is stored in the first table with one of the few types of premises SKUs, however the dimensional data only links to the ProdID. I'm trying to instruction box allows to send the parent a second table (ProdID) code if the sku is there, or a third table if it is found on this table. The main reason (in this case) I have to this ProdID is I can join the dimensional data of a fourth table.
My current query:
SELECT / * + USE_HASH (dbin, sku, xProdID, msr) * /.
dbin.snapshot_date, dbin.bin_id, dbin. ISBN,
CASE WHEN sku. ProdID IS NULL THEN xProdID.ITEM_AUTHORITY_ID
Of ANOTHER sku. ProdID
END ProdIDMaster,
dbin. OWNER, dbin. QUANTITY, dbin. CONTAINER_ID,
MSR. HEIGHT, msr. WIDTH, msr. LENGTH, msr. WEIGHT, msr. DIMENSIONAL_UOM, msr. WEIGHT_UOM,
MSR. HEIGHT * msr. WIDTH * msr. LENGTH as a Volume
OF D_BIN_ITEMS dbin
SKU of LEFT JOIN O_FCSKUS ON dbin. ISBN = sku. FCSKU
LEFT JOIN (SELECT * FROM D_FNSKU_ProdID_MAP)
WHERE REGION_ID = 1
AND SNAPSHOT_DAY = TO_DATE('{RUN_DATE_YYYY/MM/DD}','YYYY/MM/DD')) xProdID
ON dbin. ISBN = xProdID.FULFILLMENT_NETWORK_SKU
LEFT JOIN (SELECT * FROM D_MP_ProdID_PKG_MEASUREMENTS)
WHERE REGION_ID = 1 AND MARKETPLACE_ID = 1 AND PACKAGE_TYPE_ID = 1) msr
ON ProdIDMaster = msr. ProdID
WHERE dbin. WAREHOUSE_ID = "PHL5."
AND dbin. Snapshot_date = TO_DATE('{RUN_DATE_YYYY/MM/DD}','YYYY/MM/DD')
AND dbin.bin_id like '% P-1-R '.
ORDER BY dbin.bin_id;
The error I receive:
Statement 1 is invalid. ORA-00904: "ProdIDMaster": invalid identifier
ProdIDMaster appears only in two places, an alias for the case statement, as well as a side of the join statement. If I simply change the alias name, it has no effect, so I can only assume the question is how I refer to results of the case statement. I also tried to reach the word 'CASE', which returned "1 statement is not valid. "ORA-00904:"The MATTER": invalid identifier.
Any help or advice would be greatly appreciated.
Post edited by: 8ea4344e-80ea-44e7-b8ac-d482be7245a7 I made a mistake when I posted the code. The ProdID_ID shown in the join should have been ProdIDMaster. I need to change this due to the fact that the name of the column used (which is what I based my alias on) may have been considered confidential information. All the other columns names remained unchanged.

Hello

Whenever you have a problem, please post a small example data (CREATE TABLE and only relevant columns, INSERT statements) of all the tables involved, so that people who want to help you can recreate the problem and test their ideas.

Also post the exact results you want from this data, as well as an explanation of how you get these results from these data, with specific examples.

Always say what version of Oracle you are using (for example, 11.2.0.2.0). Use "SELECT * VERSION of $ v;" to get it.

See the FAQ forum: Re: 2. How can I ask a question on the forums?

When you define an alias for column (such as PriodIDMaster) in the SELECT a query clause, you can use the alias in the ORDER byclause in this request, but this is the only place in this same query, where you can use it. If you want to use anywhere, like in a join condition, then calculate the new column in a subquery; then you can use it anywhere you want in a Super request.

I see expression BOX (not the same as a declarationBOX) where when ProdIDMaster is defined, but I do not see where it is used. Are you sure that you posted the code that is causing the problem?

Join the nearest date "not used".

Result:
st_id end_id
start0 end0
Start1 End2
Start2 End3
start3 bout4
Debut4 end5
Debut5 end6
start0 joined end0, because the closer to the date of the next 31-dec-2014 is 1 January 2015
Start1 joined end2, because the closer to the date of the next January 3, 2015 is January 13, 2015.
Start2 joined end3, because as well as the date of the next more close January 5, 2015 is 13 January 2015, this is already accompanied Start1, so she joined next January 15, 2015.
start3 joined bout4, because the date of the next although most close January 7, 2015 is 13 January 2015, this one is already joined by Start1, earliest date is January 15, 2015, but is also already joined by start2, then he joined the next available date January 17, 2015.

[UPDATE: changed line 37 to add "or cnt > = 0".] [This covers cases where there are more departures that ends at first.]

Jiri.Machotka - Oracle wrote:

I found a non recursive algorithm for this problem...

I came up with something similar: no recursion, no joins, each table read only once.
1. UNION ALL marked times 1 tables, with lines of departure and end marked lines - 1
2. Order by date (first lines) and get a combination of 1's and - 1's.
  so when there are too many lines to end, the sum is negative.
3. Get the previous cumulative minimum! Then take that end with a sum running lines, at less than the previous minimum.
4. The remaining lines will have an end of line for each line of departure. Now number lines starting from 1 to N and the lines at the end of 1 to N, then match lines start and end in pairs. I use PIVOT to do this.
