Driver interface

The Driver interface is the Java™ SQL framework that allows for multiple database drivers.

When a Driver class is loaded, it should create an instance of itself and register it with the DriverManager. This means that a user can load and register the DB2^® Everyplace^® JDBC driver by calling:

Class.forName("com.ibm.db2e.jdbc.DB2eDriver")

java.sql package

public interface Driver

Table 1 lists the methods in the Driver interface that are supported by DB2 Everyplace.

Table 1. Driver interface methods
Method return value type	Method
`boolean`	acceptsURL(String url) Returns true if the driver thinks that it can open a connection to the given URL.
`Connection`	connect(String url, java.util.Hashtable info) DB2 Everyplace overloaded method for class library configurations that do not support java.util.Properties. See connect(String url, Properties info) for supported key/value pairs.
`Connection`	connect(String url, Properties info) Attempts to make a database connection to the given URL. The java.util.Properties argument can be used to pass arbitrary string tag/value pairs as connection arguments. DB2 Everyplace supports the following driver-specific key and value pairs: Key: DB2e_ENCODING Value: character encoding Key: ENABLE_DELETE_PHYSICAL_REMOVE Value: true, false Default: false Key: ENABLE_DIRTY_BIT_SET_BY_APPLICATION Value: true, false Default: false Key: ENABLE_FILENAME_FORMAT_83 Value: true, false Default: false Key: ENABLE_IO_WRITETHROUGH Value: true, false Default (Windows^® and Linux^® x86 platforms only): false Default (Other platforms): true Restriction: The ENABLE_IO_WRITETHROUGH key affects only Windows and Linux x86 platforms. It has no effect on other platforms. Key: ENABLE_READ_INCLUDE_MARKED_DELETE Value: true, false Default: false Key: ENABLE_REORG Value: true, false Default: true Key: ENABLE_SHARED_DATABASE_ACCESS Value: true, false Default: false Key: ENABLE_TABLE_CHECKSUM Value: true, false Default: false Key: LOCK_TIMEOUT Value: number of seconds to wait for a lock to be obtained before rolling back a transaction. Default: 20 Key: LOGIN_TIMEOUT Value: number of seconds to wait for a login request to complete before returning control to the application Default: 0 Key: password Value: user password Key: user Value: user name
`int`	getMajorVersion() Gets the driver's major version number.
`int`	getMinorVersion() Gets the driver's minor version number.
`boolean`	jdbcCompliant() Reports whether this driver is a genuine JDBC COMPLIANT™ driver.

Example: The following example illustrates how to create a Properties object and how to use the setProperty() method.

Properties props = new Properties();
props.setProperty("ENABLE_REORG", "false");
props.setProperty("LOCK_TIMEOUT", "200");
props.setProperty("ENABLE_SHARED_DATABASE_ACCESS" , "true");
props.setProperty("ENABLE_IO_WRITETHROUGH","true");
props.setProperty("ENABLE_TABLE_CHECKSUM", "true");
Connection con = DriverManager.getConnection(url, props);
