Hello Community,
Can someone help me compile a query that will select a table based on item in a row.
We have a database that is updated daily with various tables.
At the moment the database has Three tables. TableOne has a load_id of 1111, TableTwo has a load_id of 1122, and TableThree has a load_id of 1133.
I'm trying to write a query that will select a table in the database based on the value of the load_id number. So, if TableThree arrived in the database with LOAD_ID 1133 before before TableTwo with LOAD_ID 1122 I 'don't' want my query to select TableThree,
but wait until TableTwo has arrived in the database before selecting TableThree. Likewise, if table TableTwo arrived in the database with LOAD_ID 1122 before TableOne with LOAD_ID 1111 I don't want my query to select TableTwo before TableOne.
The best way I think I can explain it is like this:
select * from TableThree where LOAD_ID = 1133, but only if in a previous select statement I checked for LOAD_ID 1122 from a previous table(TableTwo in this case) and successfully found LOAD_ID = 1122.
I hope I have described the question sufficent for a good response
You're help is very much appreciated.
