hi,all for example tableA create table tableA ( id serial, a integer, b integer, c integer ); insert into tableA (a,b,c) values (12,34,56);
then, select id from tableA where (a||b||c)=123456; in postgresql version 8.2.11,it works. but in postgresql version 8.3.6,the error as bellow: ERROR: operator does not exist: integer || integer LINE 1: select id from tableA where (a||b||c)=123456; ^ HINT: No operator matches the given name and argument type(s). You might need to add explicit type casts.
is it a bug in 8.2.11 or I install 8.3.6 not completely?
