参数

connection_id

ODBC 连接标识符，详见 odbc_connect()。

返回值

Returns the list of input and output parameters, as well as the columns that make up the result set for the specified procedures. Returns an ODBC result identifier 或者在失败时返回 FALSE.

The result set has the following columns:

  • PROCEDURE_CAT
  • PROCEDURE_SCHEM
  • 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
  • SQL_DATETIME_SUB
  • CHAR_OCTET_LENGTH
  • ORDINAL_POSITION
  • IS_NULLABLE
Drivers can report additional columns.

The result set is ordered by PROCEDURE_CAT, PROCEDURE_SCHEM, PROCEDURE_NAME and COLUMN_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
)
