Problem relates to ibm_db2-1.6.5 and DB2 v9.5.0.0 LINUXAMD6495.

I called a stored procedure with a blob parameter as follows:

    $stmt = db2_prepare($conn, $sqlcmd);
    $par_inid = 0;
    $par_indata = "00000000001111111111";
    $par_outrc = 0;
    db2_bind_param($stmt, 1, "par_inid", DB2_PARAM_IN);
    db2_bind_param($stmt, 2, "par_indata", DB2_PARAM_IN,DB2_BINARY);
    db2_bind_param($stmt, 3, "par_outrc", DB2_PARAM_OUT);
    if (db2_execute($stmt) )

The DB2 stored procedure raises an error with [IBM][CLI
Driver][DB2/LINUXX8664] SQL0438N  Application raised error with
diagnostic text: "Id not found".  SQLSTATE=77100.

But the db2_execute() function returns TRUE as if it was successfull.

I added some missing error handling code in ibm_db2.c - db2_execute() to
get the correct behaviour (see code below). The while loop did not
handle a SQL_ERROR of SQLParamData() as it occurs in my case. My case
was that the SQLExecute() requested one more data packet
(SQL_NEED_MORE). The next call to SQLParamData() within the while-loop
returned a sql error raised by the application because of an invalid id.
This error was not covered and db2_execute() returned with TRUE

Modified code (starts at line# 3277):

if ( rc == SQL_NEED_DATA ) {
	while ( (rc = SQLParamData((SQLHSTMT)stmt_res->hstmt, (SQLPOINTER
*)&valuePtr)) == SQL_NEED_DATA ) {
		/* passing data value for a parameter */
		rc = SQLPutData((SQLHSTMT)stmt_res->hstmt,
		if ( rc == SQL_ERROR ) {
			php_error_docref(NULL TSRMLS_CC, E_WARNING, "Sending data failed");
			_php_db2_check_sql_errors(stmt_res->hstmt, SQL_HANDLE_STMT, rc, 1,
	if ( rc == SQL_ERROR ) {
		php_error_docref(NULL TSRMLS_CC, E_WARNING, "Statement Execute
		_php_db2_check_sql_errors(stmt_res->hstmt, SQL_HANDLE_STMT, rc, 1,
