示例

示例 #1 odbc_next_result()

<?php
$r_Connection = odbc_connect($dsn, $username, $password);

$s_SQL = <<<END_SQL
SELECT '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));
?>

以上示例会输出：

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)
