(PHP 4, PHP 5, PHP 7)

odbc_procedurecolumns — Retrieve information about parameters to procedures

### Description

odbc_procedurecolumns ( resource `$connection_id` ) : resource|false
odbc_procedurecolumns ( resource `$connection_id` , string `$catalog` , string `$schema` , string `$proc` , string `$column` ) : resource|false

Retrieve information about parameters to procedures.

### Parameters

`connection_id`

  The ODBC connection identifier, see odbc_connect() for details.

`catalog`

  The catalog ('qualifier' in ODBC 2 parlance).

`schema`

  The schema ('owner' in ODBC 2 parlance). This parameter accepts the following search patterns: `%` to match zero or more characters, and `_` to match a single character.

`proc`

  The proc. This parameter accepts the following search patterns: `%` to match zero or more characters, and `_` to match a single character.

`column`

  The column. This parameter accepts the following search patterns: `%` to match zero or more characters, and `_` to match a single character.

### Return Values

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 or `FALSE` on failure.

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`.

### Examples

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
}
?>`

The above example will output something similar to:

    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
    )
