Hello list I need help in solving ORA-918: Ambiguous field reference. All the fields are schema.tablename.fieldname. The SQL has 3 inline queries that are the same but with different months in the where clause. Simplified version: select acct ..... from tab1, tab2, .... where ....... and acct in (select acct from tab1 where balance > 7000 and month = 2) and acct in (select acct from tab1 where balance > 7000 and month = 3) and acct in (select acct from tab1 where balance > 7000 and month = 4) group by acct;
Now the query runs OK with only one sub query. Oracle 8.1.6.3.4 on NT. I already replaced the three IN with 3 = select count() where month in (2,3,4) and it works, but I would like to know why the original didn't.
