ODBC_NEXT_RESULT(3) 1 ODBC_NEXT_RESULT(3)odbc_next_result - Checks if multiple results are availableSYNOPSIS
bool odbc_next_result (resource $result_id)
DESCRIPTION
Checks if there are more result sets available as well as allowing access to the next result set via odbc_fetch_array(3),
odbc_fetch_row(3), odbc_result(3), etc.
PARAMETERS
o $result_id
- The result identifier.
RETURN VALUES
Returns TRUE if there are more result sets, FALSE otherwise.
EXAMPLES
Example #1
odbc_next_result(3)
<?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));
?>
The above example will output:
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)
