SQL specific to distributed relational database and SQL CALL

During the precompile process of a distributed DB2 Universal Database™ for iSeries™ application, the i5/OS™ licensed program might build SQL packages to be run on an application server (AS).

After it is compiled, a distributed SQL program and package must be compatible with the servers that are being used as application receivers and application servers. The Prepare distributed relational database programs topic gives you more information about the changes to the precompile process and the addition of SQL packages.

This topic collection gives an overview of the SQL statements that are used with distributed relational database support and some things for you to consider about coexistence with other servers.

• Distributed relational database statements
  The statements included with the SQL language specifically support a distributed relational database.
• SQL CALL statement (stored procedures)
  The SQL CALL statement is not actually specific to distributed relational databases, but a discussion of it is included here because its main value is in distributing application logic and processing.
• DB2 Universal Database for iSeries coexistence
  When you write and maintain programs for a distributed relational database using the SQL language, you need to consider the other servers in the distributed relational database network.
