Here’s a simple little trick for Application Engines that have Temporary Tables assigned.
When you have temporary tables, you don’t know for sure which Temporary Table it is using. You could write a quick select and change the number on the end until you find the one you are looking for, but here is a slightly quicker method.
Note: This is designed for Oracle, but you could easily change it up to work with SQL Server.
First, build a select statement that will list all of the tables. We’ll assume our Temporary Table Record is MY_TEMP_TAO. You can substitute with your specific record.
SELECT 'UNION SELECT ''' || TABLE_NAME || ''' TBL, A.* FROM SYSADM.' || TABLE_NAME || ' A'
FROM DBA_TABLES
WHERE table_name LIKE 'PS_MY_TEMP_TAO%';
Update (thanks to Nicolas): You can avoid having to remove the first UNION if you use something more like this:
SELECT 'SELECT ''' || TABLE_NAME || ''' TBL, A.* ' ||
'FROM SYSADM.' || TABLE_NAME || ' A' ||
case when count(*)over()=rownum
then ';' else ' UNION ' end
FROM ALL_TABLES
WHERE table_name LIKE 'PS_MY_TEMP_TAO%';
The output should look something like this:
UNION SELECT 'PS_MY_TEMP_TAO' TBL, A.* FROM SYSADM.PS_MY_TEMP_TAO A
UNION SELECT 'PS_MY_TEMP_TAO1' TBL, A.* FROM SYSADM.PS_MY_TEMP_TAO1 A
UNION SELECT 'PS_MY_TEMP_TAO2' TBL, A.* FROM SYSADM.PS_MY_TEMP_TAO2 A
UNION SELECT 'PS_MY_TEMP_TAO3' TBL, A.* FROM SYSADM.PS_MY_TEMP_TAO3 A
UNION SELECT 'PS_MY_TEMP_TAO4' TBL, A.* FROM SYSADM.PS_MY_TEMP_TAO4 A
UNION SELECT 'PS_MY_TEMP_TAO5' TBL, A.* FROM SYSADM.PS_MY_TEMP_TAO5 A
UNION SELECT 'PS_MY_TEMP_TAO6' TBL, A.* FROM SYSADM.PS_MY_TEMP_TAO6 A;
You just simply need to delete the first Union to make something like this:
SELECT 'PS_MY_TEMP_TAO' TBL, A.* FROM SYSADM.PS_MY_TEMP_TAO A
UNION SELECT 'PS_MY_TEMP_TAO1' TBL, A.* FROM SYSADM.PS_MY_TEMP_TAO1 A
UNION SELECT 'PS_MY_TEMP_TAO2' TBL, A.* FROM SYSADM.PS_MY_TEMP_TAO2 A
UNION SELECT 'PS_MY_TEMP_TAO3' TBL, A.* FROM SYSADM.PS_MY_TEMP_TAO3 A
UNION SELECT 'PS_MY_TEMP_TAO4' TBL, A.* FROM SYSADM.PS_MY_TEMP_TAO4 A
UNION SELECT 'PS_MY_TEMP_TAO5' TBL, A.* FROM SYSADM.PS_MY_TEMP_TAO5 A
UNION SELECT 'PS_MY_TEMP_TAO6' TBL, A.* FROM SYSADM.PS_MY_TEMP_TAO6 A;
If you know your temp table has the process instance as the key and you know the one you are looking for, you could do something like this:
SELECT * FROM (
SELECT 'PS_MY_TEMP_TAO' TBL, A.* FROM SYSADM.PS_MY_TEMP_TAO A
UNION SELECT 'PS_MY_TEMP_TAO1' TBL, A.* FROM SYSADM.PS_MY_TEMP_TAO1 A
UNION SELECT 'PS_MY_TEMP_TAO2' TBL, A.* FROM SYSADM.PS_MY_TEMP_TAO2 A
UNION SELECT 'PS_MY_TEMP_TAO3' TBL, A.* FROM SYSADM.PS_MY_TEMP_TAO3 A
UNION SELECT 'PS_MY_TEMP_TAO4' TBL, A.* FROM SYSADM.PS_MY_TEMP_TAO4 A
UNION SELECT 'PS_MY_TEMP_TAO5' TBL, A.* FROM SYSADM.PS_MY_TEMP_TAO5 A
UNION SELECT 'PS_MY_TEMP_TAO6' TBL, A.* FROM SYSADM.PS_MY_TEMP_TAO6 A;
) Z WHERE PROCESS_INSTANCE = 12345
