when creating dynamic query try to store it completey as string because you will not be able to change tableName (i havent been doing that for a long time , so possibly i can be wrong). to "exec" or "execute" command you have to pass the query as parameter. it would look like this
declare sql as varchar; Field2=new. testing_name; Field1=new.testing_id; sql:='insert into tableName'||id||' (testing_id,testing_name) values ('||Field1||','||quote_literal(Field2)||')'; exec(sql); On Thu, Jan 27, 2011 at 6:50 PM, Amitabh Kant <amitabhk...@gmail.com> wrote: > Hi > > I am trying to write a function which is being called from a trigger used > for partitioning a large table.
