When I do Cast To_number on Field1 in the query I get an error "selected non-aggregate values must be part of the associated group". Field1 is Char(5) datatype and the actual values in the field are numbers.
Whereas when I run the query with just Field1 the query runs successfully. What could be the issue? Help pls.
cast(TO_NUMBER(Field1 as integer) as Field1
from Table 1
group by 1,2
The SQL statement is syntactically incorrect.
Please, post the REAL SQL statement and the table definition.
