JDBC ISERIES DRIVER

By default, the table rows are retrieved in sequence. Applications may also use DatabaseMetaData methods to obtain information about a data source, but this is less typical. ResultSets The ResultSet interface provides access to the results generated by running queries. Java exceptions The Java language uses exceptions to provide error-handling capabilities for its programs. 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.

The RowSet interfaces define a set of core functionality that all RowSets have.

By default, the table rows are retrieved in sequence. Conceptually, data of a ResultSet can be thought of as a table with a specific number of columns and a specific number of rows. SQL statements cause the generation of ResultSet objects.

Applications may also use DatabaseMetaData methods to obtain information about a data source, but this is less typical. To complete a logical unit of work, several actions may need to be taken against a database.

They are ideal for storing serialized Java objects, Extensible Markup Language XML documents, and multimedia data such as songs, product pictures, employee iserise, and movie clips. RowSet implementation providers have considerable jddbc to define the functionality that is needed to fit their needs in a specific problem space.

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.

Accessing your IBM i database with the Java JDBC driver

An application program can have multiple connections at one time. This means iserids a single connection performs all the work of the transaction and that the connection can only work on one transaction at a time.

Advanced data types Advanced SQL3 data types give you a tremendous amount of flexibility. Statement types The Statement interface and its PreparedStatement and CallableStatement subclasses are used to process structured query language SQL commands against the database.

ResultSets The ResultSet interface provides access to the results generated by running queries. This driver is also commonly known as the native JDBC driver.

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.

Most iserise not specific to the native JDBC driver. JDBC transactions A transaction is a logical unit of work. Java exceptions The Java language uses exceptions to provide error-handling capabilities for its programs.

Within a row, column values can be accessed in any order. These settings are used for all connections created by the native JDBC driver. The following tips are considered good JDBC programming practice. However, getting the best possible performance requires that you build your applications in iserirs way that takes advantage of the strengths the native JDBC driver has to offer.

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. Database access from Java programs. 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.

It is through Connection objects that Statement objects are created for processing SQL statements against the database. JDBC provides a natural and easy-to-use mapping from the Java programming language to the abstractions and concepts defined in the SQL standard. These Connection objects can all connect to the same database or connect to different databases. This jvbc can significantly improve performance when many updates must be performed at once.
