ODBC and DB2 (PDO)

&reftitle.intro; PDO_ODBC is a driver that implements the PHP Data Objects (PDO) interface to enable access from PHP to databases through ODBC drivers or through the IBM DB2 Call Level Interface (DB2 CLI) library. PDO_ODBC currently supports three different "flavours" of database drivers: ibm-db2 Supports access to IBM DB2 Universal Database, Cloudscape, and Apache Derby servers through the free DB2 client. unixODBC Supports access to database servers through the unixODBC driver manager and the database's own ODBC drivers. generic Offers a compile option for ODBC driver managers that are not explicitly supported by PDO_ODBC. On Windows, PDO_ODBC is built into the PHP core by default. It is linked against the Windows ODBC Driver Manager so that PHP can connect to any database cataloged as a System DSN, and is the recommended driver for connecting to Microsoft SQL Server databases.

&reference.pdo-odbc.configure; &reference.pdo-odbc.ini; PDO_ODBC DSN Connecting to ODBC or DB2 databases &reftitle.description; The PDO_ODBC Data Source Name (DSN) is composed of the following elements: DSN prefix The DSN prefix is odbc:. If you are connecting to a database cataloged in the ODBC driver manager or the DB2 catalog, you can append the cataloged name of the database to the DSN. DSN The name of the database as cataloged in the ODBC driver manager or the DB2 catalog. Alternately, you can provide a complete ODBC connection string to connect to a database as described at &url.connectionstrings;. UID The name of the user for the connection. If you specify the user name in the DSN, PDO ignores the value of the user name argument in the PDO constructor. PWD The password of the user for the connection. If you specify the password in the DSN, PDO ignores the value of the password argument in the PDO constructor. &reftitle.examples; The following example shows a PDO_ODBC DSN for connecting to an ODBC database cataloged as testdb in the ODBC driver manager: The following example shows a PDO_ODBC DSN for connecting to an IBM DB2 database named SAMPLE using the full ODBC DSN syntax: The following example shows a PDO_ODBC DSN for connecting to a Microsoft Access database stored at C:\db.mdb using the full ODBC DSN syntax:
