If you are developing an application on JDBC interface for one kind of database engine this is seldom if ever necessary. This chapter describes briefly how to do basic database operations with the SQL. The parameter required by Class. Executing a simple statement Following code expects that a Connection object conn is established before calling the code. The default value is Then the code loops through the result set and prints the data in each column in each row by using getString method.

It was JavaSoft's intention to make the use of a specific JDBC driver as transparent as possible to the programmer and user. Before starting programming verify the installation by running and compiling the sample application.

The parameter required by the DriverManager. Portability reasons, for instance, can make using CallableStatement a good decision. Following code expects that a Connection object conn is established before calling the code. Class DatabaseMetadData contains information about the database behind the connection. Procedures osliddb thus used in JDBC in the same way as any statement. Once the driver is succesfully registered with the driver manager a connection is established by creating a Java Connection object with the following code.

Date 96,1,2 ; java. Note that the insert is not committed by the code unless the database is in autocommit mode. Many database servers only support stepping through the result set in a single direction and therefore prev has been left out of the standard.

A DatabaseMetaData object can be obtained from the Connection object by the code below. In some functions the JDBC specifiaction leaves mdbc details open. Executing a simple statement Following code expects that a Connection object conn is established before calling the code. A database native error code will be assigned to variable ec.

As usually, the code expects that a Connection object conn is established before calling it. The autocommit state can be monitored by Connection. The driver can be jdbbc with the three alternative ways, which are shown below.

See source code for example application sample1. The following operations are presented here. To import this package a following line is needed in the application program. If you are developing an application on JDBC interface for one kind of database engine this is seldom if ever necessary. Transactions and autocommit mode. The primary reason is because many databases soliedb not support bi-directional cursors.

The code also extracts database product name to string sName and all the views in the database to ResultSet rTables. Executing a simple statement. CallableStatement csta; int i1,i2; String s1; ResultSet res.

There a is next but no prev. JDBC interface is included in the java.

Many have argued, though, that a well-written object oriented program should not need to step backwards through a ResultSet, and that doing so may be either inefficient or result in unreliable data results. The example below illustrates running a simple SQL using this class.

It is possible to improve the performance of reading large result sets by instructiong SOLID Server to return several rows of the result set in one network message. When not in autocommit mode each transaction needs to be explicitly committed before the modifications it made can be seen to other database connections. For example, a unique key constraint violation can be recovered by assigning the row a different key.

Timestamp 96,1,2,11,11,11,0 ; pstmt. Usually this information is necessary for application development tools not actual applications. The JDBC driver manager, which is written entirely in Java, handles loading and unloading drivers and interfacing connection requests with the appropriate driver.
