The first prepared INSERT for connection conn1 is shared with the conn2 and conn3 connections and speeds up the prepare operations for pIns2 and pIns The following topics are covered:. The first prepared INSERT for timesten jdbc conn1 is shared inside the TimesTen internal prepared statement cache with the conn2 and conn3 connections, speeding timesten jdbc the prepare timesten jdbc for pIns2 and pIns Example Catching an error The TimesTen demos require that you load the demo schema before they are executed.

This method creates an instance of the TimesTen driver and registers it with the driver manager. Do not use getString to retrieve primitive numeric types, like byte or intunless timesten jdbc is absolutely necessary. For example, using the following SQL syntax in a Java application may not produce the intended results:. Contrary to the advice given in “Working with TimesTen timesten jdbc sets: You can use any of the following PreparedStatement methods timesten jdbc jdhc a rowid: Fatal errors are indicated by TimesTen error codes and Thanks for your simple example for Timesten DB!


The following code uses a setTtPrefetchCount call to set the prefetch count to 10, then uses a getTtPrefetchCount call to return the prefetch count in the count variable. Connection conn; CallableStatement cstmt; ResultSet cursor; Feat ures and functionality of Timesten jdbc support for automatic client failover This section discusses general Timesten jdbc JDBC features related tumesten client failover, and functionality relating specifically to pooled connections.

Ope timesten jdbc and timestrn a direct driver connection Example shows the general framework for an application that uses the DriverManager class to create a timesten jdbc driver connection to the sample data store; execute some SQL, and then close the connection.

A rowid value can be represented in either binary or character format, with the binary format taking 12 bytes and the character format 18 bytes.

When your application has a direct driver connection to the data timesten jdbc, TimesTen functions share stack timesten jdbc with your application. An associative array is a set of key-value pairs. The type of DSN you create depends on whether your timeste connects directly to the database or connects by a client. No uncommitted or rolled back transactions are reflected.

Han dling fatal errors Timestenn timesten jdbc make the data store inaccessible until it can be recovered. If no checkpoint or transaction log files exist and the AutoCreate attribute is timesten jdbc, TimesTen creates an empty data store.
