We had some 9i PL/SQL problem when sql invloves "UNION" and one sql selects varchar2 column with string concat and another selects char(1) column. Run the same 9i query in straight sql does not have problem. 8i does not give any problem (in both sql and pl/sql).
Guang -----Original Message----- Stephane Paquette Sent: Friday, October 31, 2003 11:04 AM To: Multiple recipients of list ORACLE-L Hi, Some people here are telling me that using char(1) is better than varchar2(1) for a field code. I do not see why. I never used char as it may cause problems when doing some comparisons. Any reasons ?
