HSCODELIST 2 (BIN, ACT_SL, ACT_CODE, ACT_VAL, ENTRY_DATE) 3 SELECT BIN, ACT_SL, ACT_CODE, ACT_VAL, ENTRY_DATE 4 FROM VIS. what could be the best approach to update this table. And moreover im using aggregate function like min(),max() group by p in each subquery like update upd set a = (select min(a) from a where upd.a=a.a group by a.p), b = (select (....) from b where upd.b=b.b), c = (select (........) from c where upd.c=c.c) Thanks for answering my question and we (our team) always admire your way of solving problems. October 08, 2003 - am UTC hscodelist is perhaps missing the mandatory primary/unique constraint on BIN?That gives me the all too familiar "[Macromedia][Seque Link JDBC Driver][ODBC Socket][Microsoft][ODBC Microsoft Access Driver] Operation must use an updateable query.

In update portion i am facing another problem by ur recomended code. INSERT into abc values (RTRIM(col1), RTRIM(col2) .)
