This procedure can significantly improve performance when many updates must be performed at once. Batch updates Batch update support allows any updates to the database jdbx be passed as a single transaction between the user program and the database. To complete a logical unit of work, several actions may need to be taken against a database.

JDBC transactions A transaction is a logical unit of work. Some time ago I used com.

Statement types The Statement interface and its PreparedStatement and CallableStatement subclasses are used to process structured query language SQL commands against the database. The RowSet interfaces define a set of core functionality that all RowSets have. An application program can have multiple connections at one time.

Email Required, but never shown. It is used primarily by application servers and tools to determine how to interact with a given data source. Sign up using Email and Password.

Applications may also use DatabaseMetaData methods to obtain information about a data source, but this is less typical. The credentials are not necessary if you are using a native driver jtNative.

SQL statements cause the generation of ResultSet objects.

This means that a single connection performs all the work of the transaction and that the connection can only work on one transaction at a time. JDBC provides a natural and easy-to-use mapping from the Java programming language to the abstractions and concepts defined in the SQL standard. Within a row, column values can be accessed in any order. It is through Connection objects that Statement objects are created for processing SQL statements against the database.

Advanced data types Advanced SQL3 data types give you a tremendous amount of flexibility.

We run on a V7R1 machine. Java exceptions The Java language uses exceptions to provide error-handling capabilities for its programs. Unlike some of the better-known interfaces of the JDBC specification, the RowSet specification is designed to be more of a framework than an actual implementation. Database access from Java programs. In this way I can open the connection using the logged in user credentials.

ResultSets The ResultSet interface provides access to the results generated by running queries. RowSet implementation providers have considerable freedom to define the functionality that is needed to fit their needs in a specific problem space.

Since many objects used in JDBC are expensive to create such as Connection, Statement, and ResultSet objects, significant performance benefits can nafive achieved by reusing these objects instead of creating every time you need them.

They are ideal for storing serialized Java objects, Extensible Markup Language XML documents, and multimedia data such as songs, product pictures, employee photographs, and movie clips.

Now I’ve developed a class that will run on AS and access the DB, but the customer doesn’t want to provide credential to access the DB, assuming that the access from inside AS should not need a user and password because the user is already logged.
