JDBC ISERIES DRIVER

SQL statements cause the generation of ResultSet objects. Database access from Java programs. Statement types The Statement interface and its PreparedStatement and CallableStatement subclasses are used to process structured query language SQL commands against the database. By default, the table rows are retrieved in sequence. Within a row, column values can be accessed in any order. 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. RowSet implementation providers have considerable freedom to define the functionality that is needed to fit their needs in a specific problem space.

Java exceptions The Java language uses exceptions to provide error-handling capabilities for its programs. 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.

It is used primarily by application servers and tools to determine how to interact with a given data source. An exception is an event that occurs when you run your program that disrupts the normal flow of instructions. Statement types The Statement interface and its PreparedStatement and CallableStatement subclasses are used to process structured query language SQL commands against the database. This procedure can significantly improve performance when many updates must be performed at once.

ResultSets The ResultSet interface provides access to the results generated by running queries. It is through Connection objects that Statement objects are created for processing SQL statements against the database.

RowSet implementation providers have considerable freedom to define the functionality that is needed to fit their needs in a specific problem space. This jdb is also commonly known as the native JDBC driver. The following tips are considered good JDBC programming practice. JDBC transactions A transaction is a logical unit of work. However, getting the best possible performance requires that you build your applications in a way that takes advantage of the strengths the native JDBC driver has to offer.

Conceptually, data of a ResultSet can be thought of as a table with a specific number of columns and a specific jdcb of rows.

Advanced data types Advanced SQL3 data types give you a tremendous amount of flexibility. They are ideal for storing serialized Java objects, Extensible Markup Language XML documents, and multimedia data such as songs, iseres pictures, employee photographs, and movie clips. JDBC provides a natural and easy-to-use mapping from the Java programming language to the abstractions and concepts defined in the SQL standard.

Batch updates Batch update support allows any updates to the database to be passed as a single transaction between the user program and the database.

SQL statements cause the generation of ResultSet objects. An application program can have multiple connections at one time.

Configuring the IBM Toolbox for Java

Unlike idbc of the better-known interfaces of the JDBC specification, the RowSet specification is designed to be more of a framework than an actual implementation.

Most are not specific to the native JDBC driver.

To complete a logical unit of work, several actions may isrries to be taken against a database. These settings are used for all connections created by the native JDBC driver.

Database access from Java programs. These Connection objects can all connect to the same database or connect to different databases.

Applications may also use DatabaseMetaData methods to obtain information about a data source, but this is less typical. The RowSet interfaces define a set of core functionality that all RowSets have. Since many objects used in JDBC are expensive to create such as Connection, Statement, and ResultSet objects, significant performance benefits can be achieved by reusing these objects instead of creating every time you need them.

By default, the table rows are retrieved in sequence. Within a row, column values can be accessed in any order.
