Bug description:  ibm_db2 / db2_execute failure

Description:
------------
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) )
      <ok>
    else
      <error>

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 (=successful).

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,
(SQLPOINTER)(((zvalue_value*)valuePtr)->str.val),
((zvalue_value*)valuePtr)->str.len);
                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,
NULL, -1, 1 TSRMLS_CC);
                        RETVAL_FALSE;
                }
        }
        if ( rc == SQL_ERROR ) {
                php_error_docref(NULL TSRMLS_CC, E_WARNING, "Statement Execute
Failed");
                _php_db2_check_sql_errors(stmt_res->hstmt, SQL_HANDLE_STMT, rc, 
1, NULL,
-1, 1 TSRMLS_CC);
                RETVAL_FALSE;
        }
        
}

Hope that this is not a "huge text" ;-)
