I have solved the problem by mapping a character array into integer array: struct data { int id; char a[100]; } temp; After getting temp from exec sql select ....., I use strtol() to convert temp.a into a integer array, and it works! I now have another problem that is I can get the tuples by sqlca.sqlerrd[2], but how can I get the type of each field that has been selected? In libpq++ FieldType(n) can get the type of field, how about in ecpg? Thanks S.F.Lee --- Michael Meskes <meskes@postgreSQL.org> wrote: > On Mon, Dec 27, 1999 at 01:51:39AM -0800, S.F.
