Stored Procedures

Many database management systems can store individual SQL statements or sets of SQL statements in a database, so that programs accessing that database can invoke them. Such named collections of SQL are called stored procedures. JDBC enables programs to invoke stored procedures using objects that implement interface CallableStatement. CallableStatements can receive arguments specified with the methods inherited from interface PreparedStatement. In addition, CallableStatements can specify output parameters in which a stored procedure can place return values. Interface CallableStatement includes methods to specify which parameters in a stored procedure are output parameters. The interface also includes methods to obtain the values of output parameters returned from a stored procedure.

Portability Tip 25.7

Although the syntax for creating stored procedures differs across database management systems, interface CallableStatement provides a uniform interface for specifying input and output parameters for stored procedures and for invoking stored procedures.

Portability Tip 25.8

According to the Java API documentation for interface CallableStatement, for maximum portability between database systems, programs should process the update counts or ResultSets returned from a CallableStatement before obtaining the values of any output parameters.
