> Select distinct col1 as alias_col1

> where col2 = (SELECT max(t2_col1) as currentdate from table2 limit 1)

> Error: Error while compiling statement: FAILED: SemanticException Line 0:-1 Unsupported SubQuery Expression '1': Only SubQuery expressions that are top level conjuncts are allowed (state=42000,code=40000) {code}
> Workaround is either remove distinct column alias "alias_col1" or use alias in order by.
