db2_client_info — Returns an object with properties that describe the DB2 database client

说明

db2_client_info ( resource $connection ) : object

This function returns an object with read-only properties that return information about the DB2 database client. The following table lists the DB2 client properties:

DB2 client properties

Property name	Return type	Description
APPL_CODEPAGE	int	The application code page.
CONN_CODEPAGE	int	The code page for the current connection.
DATA_SOURCE_NAME	string	The data source name (DSN) used to create the current connection to the database.
DRIVER_NAME	string	The name of the library that implements the DB2 Call Level Interface (CLI) specification.
DRIVER_ODBC_VER	string	The version of ODBC that the DB2 client supports. This returns a string "MM.mm" where MM is the major version and mm is the minor version. The DB2 client always returns "03.51".
DRIVER_VER	string	The version of the client, in the form of a string "MM.mm.uuuu" where MM is the major version, mm is the minor version, and uuuu is the update. For example, "08.02.0001" represents major version 8, minor version 2, update 1.
ODBC_SQL_CONFORMANCE	string	The level of ODBC SQL grammar supported by the client: MINIMUM Supports the minimum ODBC SQL grammar. CORE Supports the core ODBC SQL grammar. EXTENDED Supports extended ODBC SQL grammar.
ODBC_VER	string	The version of ODBC that the ODBC driver manager supports. This returns a string "MM.mm.rrrr" where MM is the major version, mm is the minor version, and rrrr is the release. The DB2 client always returns "03.01.0000".

参数

connection

Specifies an active DB2 client connection.

返回值

Returns an object on a successful call. Returns false on failure.

范例

Example #1 A db2_client_info() example

To retrieve information about the client, you must pass a valid database connection resource to db2_client_info().

<?php$conn = db2_connect( 'SAMPLE', 'db2inst1', 'ibmdb2' );$client = db2_client_info( $conn );if ($client) {    echo "DRIVER_NAME: ";           var_dump( $client->DRIVER_NAME );    echo "DRIVER_VER: ";            var_dump( $client->DRIVER_VER );    echo "DATA_SOURCE_NAME: ";      var_dump( $client->DATA_SOURCE_NAME );    echo "DRIVER_ODBC_VER: ";       var_dump( $client->DRIVER_ODBC_VER );    echo "ODBC_VER: ";              var_dump( $client->ODBC_VER );    echo "ODBC_SQL_CONFORMANCE: ";  var_dump( $client->ODBC_SQL_CONFORMANCE );    echo "APPL_CODEPAGE: ";         var_dump( $client->APPL_CODEPAGE );    echo "CONN_CODEPAGE: ";         var_dump( $client->CONN_CODEPAGE );}else {    echo "Error retrieving client information.     Perhaps your database connection was invalid.";}db2_close($conn);?>

以上例程会输出：

DRIVER_NAME: string(8) "libdb2.a"
DRIVER_VER: string(10) "08.02.0001"
DATA_SOURCE_NAME: string(6) "SAMPLE"
DRIVER_ODBC_VER: string(5) "03.51"
ODBC_VER: string(10) "03.01.0000"
ODBC_SQL_CONFORMANCE: string(8) "EXTENDED"
APPL_CODEPAGE: int(819)
CONN_CODEPAGE: int(819)
