• PROCEDURE_NAME
• COLUMN_NAME
• COLUMN_TYPE
• DATA_TYPE
• TYPE_NAME
• COLUMN_SIZE
• BUFFER_LENGTH
• DECIMAL_DIGITS
• NUM_PREC_RADIX
• NULLABLE
• REMARKS
• COLUMN_DEF
• SQL_DATA_TYPE

范例

Example #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}?>

以上例程的输出类似于：

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
)
