Returns an ODBC result identifier 或者在失败时返回 false.
The result set has the following columns:
PROCEDURE_CATPROCEDURE_SCHEMPROCEDURE_NAMECOLUMN_NAMECOLUMN_TYPEDATA_TYPETYPE_NAMECOLUMN_SIZEBUFFER_LENGTHDECIMAL_DIGITSNUM_PREC_RADIXNULLABLEREMARKSCOLUMN_DEFSQL_DATA_TYPESQL_DATETIME_SUBCHAR_OCTET_LENGTHORDINAL_POSITIONIS_NULLABLE
The result set is ordered by PROCEDURE_CAT, PROCEDURE_SCHEM,
PROCEDURE_NAME and COLUMN_TYPE.

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
