| We're experimenting with the "use declare/fetch" setting in our MS Access/DAO - PG 8.1 environment. We're using the psqlODBC snapshot driver version, 8.02.01.03. However, we're experiencing a problem. With the "use declare/fetch" setting on we get an error on the (cache size - 49)th call to a dao recordset's MoveNext method. So with our current cache size setting of 500, the 451st call to MoveNext generates an ODBC error. With the cache size set to 100, the 51st call to MoveNext fails. See below for the relevant COMM log entries. We have tried various arguments to OpenRecordset to no avail(dbOpenDynaset, dbOpenSnapshot, etc.). I'm guessing there's a setting somewhere that we're missing that needs to be set in addition. Again, thanks in advance for your attention... garner PS. Is it still true that the SQLExtendedFetch calls, bookmarks, movelast, etc., are not supported with the "use declare/fetch" setting? --LOG-- STATEMENT ERROR: func=SC_fetch, desc='', errnum=1, errmsg='Error fetching next row' ------------------------------------------------------------ hdbc=11e53a20, stmt=11e58dc0, result=11e5d790 prepare=0, internal=0 bindings=121144e8, bindings_allocated=2 parameters=0, parameters_allocated=0 statement_type=0, statement='SELECT "table_schema" ,"table_name" FROM "information_schema"."tables" WHERE ("table_schema" IN ('p_0001' ,'m' ,'public' ) ) ORDER BY "information_schema"."tables"."table_schema" ,"information_schema"."tables"."table_name" ' stmt_with_params='declare "SQL_CUR11E58DC0" cursor with hold for SELECT "table_schema" ,"table_name" FROM "information_schema"."tables" WHERE ("table_schema" IN ('p_0001' ,'m' ,'public' ) ) ORDER BY "information_schema"."tables"."table_schema" ,"information_schema"."tables"."table_name" ' data_at_exec=-1, current_exec_param=-1, put_data=0 currTuple=499, current_col=1, lobj_fd=-1 maxRows=0, rowset_size=1, keyset_size=0, cursor_type=0, scroll_concurrency=1 cursor_name='SQL_CUR11E58DC0' ----------------QResult Info ------------------------------- fields=11e5a768, backend_tuples=1211d010, tupleField=0, conn=11e53a20 fetch_count=1, num_total_rows=500, num_fields=2, cursor='SQL_CUR11E58DC0' message='(NULL)', command='FETCH', notice='(NULL)' status=100, inTuples=0 CONN ERROR: func=SC_fetch, desc='', errnum=0, errmsg='(NULL)' ------------------------------------------------------------ henv=11e539f0, conn=11e53a20, status=1, num_stmts=16 sock=11e56568, stmts=11e58640, lobj_type=-999 ---------------- Socket Info ------------------------------- socket=1360, reverse=0, errornumber=0, errormsg='(NULL)' buffer_in=300246576, buffer_out=300250680 buffer_filled_in=3521, buffer_filled_out=0, buffer_read_in=3521 ---------------------------(end of broadcast)--------------------------- TIP 6: explain analyze is your friend |
