The following bug has been logged online: Bug reference: 2629 Logged by: Andy McCurdy Email address: [EMAIL PROTECTED] PostgreSQL version: 8.1.4 Operating system: Windows XP Description: libpq - Cannot deallocate prepared statement created with PQprepare() Details:
According to http://www.postgresql.org/docs/8.1/interactive/libpq-exec.html, the last statement in the PQprepare() function description suggests that a user can run the statement: "DEALLOCATE [statement name]" with PQexec() to deallocate a statement prepared with PQprepare(). When trying to do this, I consistently get the error message: ERROR: prepared statement "[statement name]" does not exist Here's a snippet of code that illustrates what I am attempting to do: int main() { PGconn* conn; PGresult* result; conn = PQsetdbLogin("localhost", "5432", NULL, NULL, "postgres", "postgres", "postgres"); result = PQprepare(conn, "MyQuery", "select * from pg_stat_activity", 0, NULL); /* THE FOLLOW PQEXEC() FAILS. Error message says: ERROR: prepared statement "myquery" does not exist" */ result = PQexec(conn, "DEALLOCATE MyQuery"); result = PQexec(conn, "PREPARE MyQuery AS select * from pg_stat_activity"); /* THIS WORKS */ result = PQexec(conn, "DEALLOCATE MyQuery"); return 0; } ---------------------------(end of broadcast)--------------------------- TIP 2: Don't 'kill -9' the postmaster
