Open SQL/JDBC 

Purpose

The aim of Open SQL for Java is to enable Java users to develop database access independently of a particular database system. This goal is achieved by:

·        Defining a subset of SQL that is comprehensible for all database systems. For more information, see Open SQL Grammar.

·        Defining a subset of JDBC that is compatible with all database systems. This section deals with Open SQL/JDBC.

Features

Although JDBC is a standard that is recognized by the Java community, existing implementations of various database vendors differ in details. Open SQL/JDBC (Open JDBC) is the JDBC-compatible implementation of the essential parts of the JDBC standard. This implementation enables you to access portably all database systems that are supported by SAP. Open SQL/JDBC implements the interfaces from the Java package java.sql.*.

Using Open JDBC, you can select and modify data in existing database tables. The tables are created in the Java Dictionary.

For more information about the most important aspects of Open JDBC use, see:

·        Inserting Data into A Table

·        Using Queries

·        Semantics of the Data Types DATE, TIME, and TIMESTAMP

·        Transactions in Open SQL/JDBC

·        Native SQL Access
