范例
Example #1 odbc_next_result()
<?php$r_Connection = odbc_connect($dsn, $username, $password);$s_SQL = <<<END_SQLSELECT 'A'SELECT 'B'SELECT 'C'END_SQL;$r_Results = odbc_exec($r_Connection, $s_SQL);$a_Row1 = odbc_fetch_array($r_Results);$a_Row2 = odbc_fetch_array($r_Results);echo "Dump first result set";var_dump($a_Row1, $a_Row2);echo "Get second results set ";var_dump(odbc_next_result($r_Results));$a_Row1 = odbc_fetch_array($r_Results);$a_Row2 = odbc_fetch_array($r_Results);echo "Dump second result set ";var_dump($a_Row1, $a_Row2);echo "Get third results set ";var_dump(odbc_next_result($r_Results));$a_Row1 = odbc_fetch_array($r_Results);$a_Row2 = odbc_fetch_array($r_Results);echo "Dump third result set ";var_dump($a_Row1, $a_Row2);echo "Try for a fourth result set ";var_dump(odbc_next_result($r_Results));?>
以上例程会输出：
Dump first result set array(1) {
["A"]=>
string(1) "A"
}
bool(false)
Get second results set bool(true)
Dump second result set array(1) {
["B"]=>
string(1) "B"
}
bool(false)
Get third results set bool(true)
Dump third result set array(1) {
["C"]=>
string(1) "C"
}
bool(false)
Try for a fourth result set bool(false)
