Oracle error 1002 and 3114

Question

my program is running smooth all the while, out of sudden it hit ora-1002 error subsequently hit ora-3114.
as i know the 1002 is cursor out of sequence, and 3114 is oracle not connect... what is the possible to link up this 2 error together?

Answer 1

this is part of my code...
sqlstmt.len = sprintf((char *) sqlstmt.arr,
"SELECT * from table");
EXEC SQL PREPARE edccnt3 FROM :sqlstmt;
EXEC SQL DECLARE edccnt_c3 CURSOR FOR edccnt3;
EXEC SQL OPEN edccnt_c3;
EXEC SQL FETCH edccnt_c3 into :max_txn_time_year, :last_txn_time_year;
if (max_txn_time_year > last_txn_time_year) {
     sqlstmt.len = sprintf((char *) sqlstmt.arr,     
"SELECT * from table1 where xxx);                    
} else {
sqlstmt.len = sprintf((char *) sqlstmt.arr,     
"SELECT * from table1 where xxx); }
          EXEC SQL CLOSE edccnt_c3;
sprintf(buf_stg, "SQLSTMT=[%s].", (char *) sqlstmt.arr);
log_msg(1, buf_stg);
EXEC SQL PREPARE edccnt2 FROM :sqlstmt;
EXEC SQL DECLARE edccnt_c2 CURSOR FOR edccnt2;
EXEC SQL OPEN edccnt_c2;
EXEC SQL FETCH edccnt_c2 into :min_txn_time_stg;
if ((sqlca.sqlcode == ORA_SUCCESS ) && (cnt == 0)) {
last_txn_time_stg[18] = 0x00;
else if (sqlca.sqlcode != ORA_SUCCESS ) {
/*error happen here*/
sprintf(buf_stg, "Failed with oracle error code %d", curr_eqptype, sqlca.sqlcode);
log_msg(1, buf_stg);
continue;
}
