For example, if t1.a1 is defined as an INTEGER and t2.a2 is defined as BIGINT, using these two columns in a join predicate will result in t1.a1 to be converted to BIGINT implicitly and explicit cast will not be needed: select * from t1, t2 where t1.a1 = t2.a2; -- This message was sent by Atlassian JIRA (v6.3.4#6332)
