范例

示例 #1 List Columns of a stored Procedure

<?php
$conn = odbc_connect($dsn, $user, $pass);
$columns = odbc_procedurecolumns($conn, 'TutorialDB', 'dbo', 'GetEmployeeSalesYTD;1', '%');
while (($row = odbc_fetch_array($columns))) {
    print_r($row);
    break; // further rows omitted for brevity
}
?>

以上例程的輸出類似于：

Array
(
    [PROCEDURE_CAT] => TutorialDB
    [PROCEDURE_SCHEM] => dbo
    [PROCEDURE_NAME] => GetEmployeeSalesYTD;1
    [COLUMN_NAME] => @SalesPerson
    [COLUMN_TYPE] => 1
    [DATA_TYPE] => -9
    [TYPE_NAME] => nvarchar
    [COLUMN_SIZE] => 50
    [BUFFER_LENGTH] => 100
    [DECIMAL_DIGITS] =>
    [NUM_PREC_RADIX] =>
    [NULLABLE] => 1
    [REMARKS] =>
    [COLUMN_DEF] =>
    [SQL_DATA_TYPE] => -9
    [SQL_DATETIME_SUB] =>
    [CHAR_OCTET_LENGTH] => 100
    [ORDINAL_POSITION] => 1
    [IS_NULLABLE] => YES
)
