SQL - Joins

Hi all.
I am learning join- tables in SQL.
My question relates to the use of WHERE. It is probably best if I show 2 examples:
1 SELECT ename, dname from emp e join dept d on (e.deptno = d.deptno) WHERE ename = 'Jones';
2 SELECT ename, dname from emp e, dept d where e.deptno = d.deptno
So the question is: How do I stipulate in Example 2 that I want the details returned for 'jones' ?
I have tried using AND WHERE, but it doesn't seem to work.
Any thoughts??

Just answered my own Q.!!
2 SELECT ename, dname from emp e, dept d where e.deptno = d.deptno AND ename = 'jones'
Sometimes the simplest solution works.
I have clicked answered. I presume that you cannot obtain points for answering your own question!?

SQL JOIN with BPM sql component

Hello friends.
How to use SQL JOIN with BPM sql component?
The tables objects are created but the joined tables belong to different sql components .
I tried something like that, but a error "table doesn't exist" occours.
Ex:
for each element in
SELECT imuImovelCd
FROM IMOVEIS_URBANOS,
Integracao.FGLP.IMOVEIS_PRE_EDITAIS
WHERE IMOVEIS_URBANOS.imuImovelCd = Integracao.FGLP.IMOVEIS_PRE_EDITAIS.ipeImuCd
AND Integracao.FGLP.IMOVEIS_PRE_EDITAIS.ipePedNr = 1
AND Integracao.FGLP.IMOVEIS_PRE_EDITAIS.ipePedAa = 2008
do
extend this.imoveis using cdImovel = element.imuimovelcd,
                              nrImovel = call(DEC_ENDERECO, codimovel : element.imuimovelcd, tipoimovel : 1)
end

ok, ok you are right.
When I try use SQL Statement to make a JOIN with 2 tables on different sql objects, BPM returns "table dosn't exists".
So.... I change my code. I dont know if this is the best way to do, but... i hope u, or everyone, can help me to do a best work.
This code works fine.
for each element in
SELECT ipeImuCd
     FROM Integracao.FGLP.IMOVEIS_PRE_EDITAIS
     WHERE Integracao.FGLP.IMOVEIS_PRE_EDITAIS.ipePedNr = 1
     AND Integracao.FGLP.IMOVEIS_PRE_EDITAIS.ipePedAa = 2008
do
     for each element2 in
          SELECT imuImovelDv
          FROM IMOVEIS_URBANOS
          WHERE imuImovelCd = element.ipeImuCd
     do
          extend this.imoveis using cdDvImovel = String(element2.imuImovelDv),
                                        cdImovel = Decimal(element.ipeImuCd),
                                        endereco = call(DEC_ENDERECO, codimovel : element.ipeImuCd, tipoimovel : 1)

OWB 10.2.0.4 ANSI SQL join problem

Hi
Its seams to me, that in OWB 10.2.0.4 there is something broken with ANSI SQL joins and instead of ANSI joins there is used oracle SQL joins only. Maybe someone can point some solutions? I can’t rewrite all mappings with union and other operators. And manually pl/sql editing also would be big problem.

"Am I correct in assuming you did not code ANSI joins?" -> yes, i am coding Oracle SQL joins and with this option just generating ANSI joins.
With ANSI SQL join you can use OR and IN operands (and code looks more readable).
It is question of performance (so for example 80% of dataset you can join by one column other 15% by second etc ..). So this all can be rewritten also in Split->join->union all, but if you have several such joins, this will be painfully.

However, it will depend on your Oracle Version, which you have not mentioned. If you are 10g or higher then you certainly need not worry.
If you sense a problem in performance of query, then I will suggest you read the linked threads in {message:id=9360003} and post the details as specified.
Only this will help us provide releavant suggestions and avoid guessing games.
PS:- Do not forget to post Oracle Version and the Explain Plan in {noformat}{noformat} tags, exactly as specified.

Help - Bean Binding an SQL join to a gui component(jtable) in Netbeans?

Good afternoon. I'd like to ask if there is a way to data bind an SQL Join from 2 or more tables to a
GUI component(Jtable) in Netbeans. All the tutorials show is how to bind all the fields of 1 database table
to the component. Under the BIND/ELements option the IMPORT DATA TO FORM menu only allows
you to choose 1 among the database tables from a selected database.
Is there a way to configure an SQL query and attach it to the component?
Thanks.

This is not a Swing problem. Try a NetBeans forum.

Hi,
Welcome to the forum!
To convert to ANSI syntax, replace join conditions in the WHERE clause
FROM           x
,             y
WHERE         x.x1 = y.y1
AND           x.x2 = y.y2with ON conditions in the FROM clause:
FROM           x
JOIN             y   ON    x.x1 = y.y1
                         AND   x.x2 = y.y2In inner joins, conditions that do not reference 2 tables are not really join conditions, so it doesn't matter if they are in the FROM clause or in the WHERE clause.
In your case
SM.TRANSDEFID in (999,2329,2344,2370,150000903,150005362)could be part of a join condition involving sm, or it could be in the WHERE clause. Most people find it clearer if 1-table conditions like this are in the WHERE clause.
Again, this only applies to inner joins. For outer joins, all conditions that apply to a table that may lack matching rows must be included in the FROM clause, like this:
LEFT OUTER JOIN fvstock   fvs ON   sm.propref       = fvs.recordid
                                AND fvs.fieldid = 2559
                    AND fvs.flevel   = 'F'Try it.
If you have trouble, post your best attempt, along with CREATE TABLE and INSERT statements for a little sample data from all the tables involved, and the results you want from that data. Simplify the problem. Post only the tables and columns that you don't know how to handle.
See the forum FAQ {message:id=9360002}

Pl sql join and selecting columns from join."t"."c": invalid at debug time

I noticed the error at cc.Country that is shown because cc is not yet there at compile time (got that
from searching this forum).
Isnt that a bit weak of oracle sql developer that it doesnt compile from the outside to the inside /core but
rather form top to bottom?
Am I right with my conclusion? If so, how to do it otherwise i.e. specifying that cc.country is
a column from countrycodes joined with table6 ?
SELECT DISTINCT 0,
2,
SUBSTR('metable', 0, 1) || '_ABC',
'ABC_' || 'metable',
'ABC ' ||cc.Country ,
'+'
FROM table6
LEFT JOIN COUNTRYCODE cc
ON cc.Code = metable
WHERE metable IS NOT NULL
AND metable <> ''

metalray wrote:
hi Boneist
thanks for your reply
its in a plsql procedure (10g). well as you see cc is the alias
of the table COUNTRYCODE. which does exists. the error is at 'ABC ' ||cc.Country'
telling me"PL/SQL: ORA-01747: invalid user.table.column,..."
when I put COUNTRYCODE next to table6 in the FROM it works but thats not what I want
since I want to join both tables not just select from both.Can you give us your exact code and exact error message.
I'm not finding any problem with using alias names in the query..

Malformed SQL Join Created in BO XI SP5

Hi I am receiving the following message when running a specific universe-based Crystal Report:
Error in File C:\Program Files\Business Objects\BusinessObjects Enterprise 11.5\Data\procSched\hq-erpboprod.reportjobserver\~tmp1e061e138ef0560.rpt: Failed to retrieve data from the database.
I can see why it is failing to retrieve data from the database - the SQL that the Crystal is generating is not putting the 'AND' in between each clause in the join statement (see below). However, when I build the same query in Designer, I get the correct SQL results.

Has anyone seen anything like this?
We have recently migrated from BO XI R2 SP2 to BO XI R2 SP5.
We use SQL Server 2005 SP3.

This should be set up in steps, Have you configured java AD kerberos so you can login via your web/app with AD? This is a prerequisite before setting up any type of delegation to the DB.
You can also set up SSO in the front end but this shouldn't be necessarry for delegating to the DB.
What SPN's do you need...
Well if using java AD you should have an SPN for the account running the SIA (typically BOBJCentralMS/something) This SPN needs to be set in the CMC, You will need the krb5 and bsclogin files to login to your web/app with kerberos/AD. The krb5.ini will have to have a setting forwardable = true, and finally the MSAS server will need SPN's http://support.microsoft.com/kb/917409
This a a very complex configuration and you will likely need to open an incident with support to get an engineer to help. I'm not sure where our current docs for the configuration are.

Dynamic SQL Joining between tables and Primary keys being configured within master tables

Team , Thanks for your help in advance !
I'm looking out to code a dynamic SQL which should refer Master tables for table names and Primary keys and then Join for insertion into target tables .
EG:
INSERT INTO HUB.dbo.lp_order
SELECT *
FROM del.dbo.lp_order t1
where not exists ( select *
from hub.dbo.lp_order tw
where t1.order_id = t2.order_id )
SET @rows = @@ROWCOUNT
PRINT 'Table: lp_order; Inserted Records: '+ Cast(@rows AS VARCHAR)
-- Please note Databse names are going to remain the same but table names and join conditions on keys
-- should vary for each table(s) being configured in master tables
Sample of Master configuration tables with table info and PK Info :
Table Info
Table_info_ID   Table_Name
1       lp_order
7       lp__transition_record
Table_PK_Info
Table_PK_Info_ID   Table_info_ID   PK_Column_Name
2               1   order_id
8               7   transition_record_id
There can be more than one join condition for each table
Thanks you !
Rajkumar Yelugu

Hi Rajkumar,
It is glad to hear that you figured the question out by yourself.
There's a flaw with your while loop in your sample code, just in case you hadn't noticed that, please see below.
--In this case, it goes to infinite loop
DECLARE @T TABLE(ID INT)
INSERT INTO @T VALUES(1),(3),(2)
DECLARE @ID INT
SELECT @ID = MIN(ID) FROM @T
WHILE @ID IS NOT NULL
PRINT @ID
SELECT @ID =ID FROM @T WHERE ID > @ID
So a cursor would be the appropriate option in your case, please reference below.
DECLARE @Table_Info TABLE
Table_info_ID INT,
Table_Name VARCHAR(99)
INSERT INTO @Table_Info VALUES(1,'lp_order'),(7,'lp__transition_record');
DECLARE @Table_PK_Info TABLE
Table_PK_Info_ID INT,
Table_info_ID INT,
PK_Column_Name VARCHAR(99)
INSERT INTO @Table_PK_Info VALUES(2,1,'order_id'),(8,7,'transition_record_id'),(3,1,'order_id2')
DECLARE @SQL NVarchar(MAX),
@ID INT,
@Table_Name VARCHAR(20),
@whereCondition VARCHAR(99)
DECLARE cur_Tabel_Info CURSOR
FOR SELECT Table_info_ID,Table_Name FROM @Table_Info
OPEN cur_Tabel_Info
FETCH NEXT FROM cur_Tabel_Info
INTO @ID, @Table_Name
WHILE @@FETCH_STATUS = 0
BEGIN
SELECT @whereCondition =ISNULL(@whereCondition+' AND ','') +'t1.'+PK_Column_Name+'='+'t2.'+PK_Column_Name FROM @Table_PK_Info WHERE Table_info_ID=@ID
SET @SQL = 'INSERT INTO hub.dbo.'+@Table_Name+'
SELECT * FROM del.dbo.'+@Table_Name+' AS T1
WHERE NOT EXISTS (
SELECT *
FROM hub.dbo.'+@Table_Name+' AS T2
WHERE '+@whereCondition+')'
SELECT @SQL
--EXEC(@SQL)
SET @whereCondition = NULL
FETCH NEXT FROM cur_Tabel_Info
INTO @ID, @Table_Name
END
Supposing you had noticed and fixed the flaw, your answer sharing is always welcome.
If you have any question, feel free to let me know.

SQL Join help for multiple values in single field.

Hello All,
I need a help, I have two tables T1 and T2
Content of T2 will be like
T2. ID | T2.USERNAME
ID1 | John
ID2 | Peter
ID3 | Mark
Content of T1 is like
T1.ID
ID1 ID2 ID3
ID2
ID1 ID3
I need to join these two tables and replace the T1.ID values with T2.USERNAME, for eg. Row one of T1 should be changed as John Peter Mark.
Note: ID1 ID2 ID3 is a single value.
Thanks for your help.

you cannot delete multiple table rows using a single delete command... you need either separate delete commands - each for one table or better go with foreign key set up and on delete cascade.

if we have x.name and y.name as columns of two tables (x and y), when we use getString("name") we lose the string for the second getString.
We have tried too:
getString(rsmd.getTableName(i)+".name") being rsmd a ResultSetMetaData object and i the number of the column. It wasn't successful because getTableName didn't return the table name (as we know, it returns the table name or "" if not applicable).
thanks in advance.

Is this getString("name") method used over object "Resultset" ??
U can use getString(int) instead and specify the location of the "name" attributes
Example if the SQl looks like
select x.name,y.name,x.abc,x.temp form ... bla bla
x.name is getString(1);
y.name is getString(2);
Hope this helped you
Thanks

SQL Joins & joining 4 tables help.

Hello, I'm trying to build a report to show orders shipped, and pull in costing information from my sales tables. I have 4 tables I'm using data from, and I'm linking my shipping master and shipping items tables by a left outer join on shipper number. I'm linking my sales master table and sales item table using a left outer join on sales order number. Now I need to link the 4 tables together, and everything I try spits out duplicate line items. I'm linking my shipping master table to sales order master using a inner join on sales order number. here is a copy of my query: SELECT "sorels"."fmatlcost", "sorels"."fsetupcost", "sorels"."flabcost", "sorels"."fovhdcost", "sorels"."forderqty", "shmast"."fshipdate", "shitem"."fshipqty", "shitem"."fpartno", "somast"."fusercode", "shmast"."fcbcompany" FROM (("<SQL Database>"."dbo"."somast" "somast" INNER JOIN "<SQL Database>"."dbo"."shmast" "shmast" ON "somast"."fsono"="shmast"."fcsono") LEFT OUTER JOIN "<SQL Database>"."dbo"."sorels" "sorels" ON "somast"."fsono"="sorels"."fsono") LEFT OUTER JOIN "<SQL Database>"."dbo"."shitem" "shitem" ON "shmast"."fshipno"="shitem"."fshipno" WHERE ("shmast"."fshipdate">={ts '2007-11-01 00:00:00'} AND "shmast"."fshipdate"<{ts '2007-11-30 00:00:01'}) AND "shitem"."fpartno" NOT LIKE 'PM%' ORDER BY "somast"."fusercode", "shmast"."fcbcompany"

At a glance, the problem seems to be primarily that you are not giving enopugh information to your joins to limit the data displayed. If you added an order and shipment line number to the joins this may help. Just for fun, can you put the table structures here and I'll give it a whirl? Alternatively, email me a sample from all four tables and I'll put something together and send it back. Use graemeg AT falum DOT co DOT nz.
