POWERUp 2019

Among the many modernization technologies available on IBM i, SQL is perhaps the one best known by RPG developers. This session won't focus on how to write SQL statements, but rather how to write scripts that combine SQL statements together into procedures that encapsulate database access and core business logic for use in a myriad of modern applications. We'll discuss how stored procedures fit into a modernization strategy, and why they are such a good fit for RPG programmers who want to participate in modernization projects. They're also a great fit for anyone new to IBM I who needs access to its database for applications in PHP, Java, Crystal Reports, IBM Web Query, Excel, Web Services, conversion projects, etc. SQL is often embedded in other languages, such as RPG, PHP, Java, etc. But IBM provides the SQL Procedure Language (SQL/PL), which can be used to code complex or multiple SQL statements into procedures that can form the backbone of a service oriented architecture. These procedures can be called from any programming language. This can simplify the database access code in PHP, Java, and other host languages, while taking full advantage of DB2-specific SQL features. Come and learn about the many features and benefits of SQL stored procedures, how to code them, and how to use them in your modernization strategy.
