In order to understand how we came to the development of the DB2 Universal Driver, you need to understand how the JDBC specification defines the different types of drivers in the Java world. Now with this knowledge, you can look at specific information with respect to the Type 2 and Type 4 drivers and examine the advantages of using the Type 4 driver in your application development. No special installation is required; you just need to make sure that you have the appropriate Java developer kit downloaded for your particular platform. See Related topics. The difference between the two JDBC drivers is shown in the way that they make their connections. It has the capability of processing a result set and sending db2 udb jdbc to the requestor.

The way you actually write the code to load the driver db2 udb jdbc depends on which driver you want to use. There are two ways the connection can be established. As with all JDBC resources, invoke the connections close method when you are done with the connection.

Db2 udb jdbc example, if the login timeout expires, any connection attempts stop. The Db2 udb jdbc property specifies the wait interval, in seconds, used between retry attempts. The number of seconds the driver waits between connection retry attempts when ConnectionRetryCount is set to a positive integer. Controls how data conversions are handled for null values.

If set to 1 the defaultdb2 udb jdbc driver checks the data type being requested against the data type of the table column storing the data. If a conversion between db2 udb jdbc requested type and column type is not defined, the driver generates an "unsupported data conversion" exception regardless of the data type of the column value. If set to 0, the driver does not perform the data type check if the value of the column is null.

This allows null values to be returned even though a conversion between the requested type and the column type is undefined. Determines whether the driver automatically creates required DB2 packages. If set to true, the DB2 driver automatically creates required DB2 packages, even if db2 udb jdbc already exist. Existing DB2 packages are replaced by the new packages. If set to false the defaultthe driver determines if the required DB2 packages exist.

If they do not, the driver automatically creates them. The name of the database to which you want to connect used with UDB. Db2 udb jdbc also Database Connection Property. The maximum number of prepared statements that the DB2 driver can have open at any time.

The value must be a positive integer. Determines whether a cancel request sent by the driver as the result of a query timing out is subject to the same query timeout value as the statement it cancels. If set to true, the cancel request times out using the same timeout value, in seconds, that is set for the statement it cancels. For example, if your application calls Statement. If the cancel request times out, because the server is down, for example, the driver throws an exception indicating db2 udb jdbc the cancel request was timed out and the connection is no longer valid.

If set to false the defaultthe cancel request does not time out. Determines whether a DB2-specific encryption algorithm is used to encrypt and decrypt data transmitted over the network between the driver and database server. If set to noEncryption the defaultdata is not encrypted or decrypted. If the database server does not support DES encryption, the connection fails and the driver throws an exception. If the database server does not support DES encryption, the driver attempts to establish an unencrypted connection.

This property is ignored if the GrantExecute property is set to false. Specifies one or multiple SQL commands to be executed by the driver after it has established the connection to the db2 udb jdbc and has performed all initialization for the connection. Multiple commands must be separated by semicolons. In addition, if this property is specified in a connection URL, the entire value db2 udb jdbc be enclosed in parentheses when multiple commands are specified.

Modifications for DB2 LUW

If the execution of a SQL command fails, the connection attempt also fails and the driver throws an exception indicating which SQL command or commands failed.Which JDBC driver (JCC) version corresponds with each DB2 release and Fix Pack level? NOTE: There were no new JDBC APARS for Fix Pack The most recent step in the evolution of Java development in the DB2 environment is the Db2 udb jdbc UDB JDBC Universal Driver. This new driver.
