Have you been memorizing field names or relying on F4 prompting?
Written by Steven Goetjen
When creating file joins using interactive SQL (STRSQL), it's sometimes difficult to remember the field names that you want to join. I typically don't memorize field names and totally rely on the F4 prompting to get the names from the "SELECT fields" line.

With a recent V6R1 PTF, SQL stored procedures can now benefit from the improved performance offered by IBM i service program objects. By Kent Milligan The usage of SQL stored procedures by IBM i applications and programs continues to rise. For quite awhile, applications have had the ability to leverage the performance benefits offered by IBM i service program objects. With a recent V6R1 PTF, SQL stored procedures can now benefit from the improved performance offered by IBM i service program objects. When an SQL stored procedure is created, DB2 for i generates and creates an ILE C program object to implement the business logic specified by the programmer. For example, when the following procedure is created, it will result in DB2 generating an ILE C program object (*PGM) named ADD_PGM in the QGPL library. Whenever an application invokes the ADD_PGM, DB2 will transparently call the generated C program object. |

Do you realize how much simpler your life can be with SQL triggers? By Kent Milligan SQL triggers have been available on DB2 for i since V5R1. The SQL trigger support provides a fast and easy way to create triggers without the extra steps of compiling a program object. In addition, the SQL trigger syntax insulates programmers from having to navigate the trigger buffer associated with external (i.e., non-SQL) triggers. |

Do you think writing embedded SQL code for RPG is more complex and time-consuming than it should be? You're not alone! By Scott Salisbury Have you ever started down the path to creating an SQLRPGLE program only to turn back and do it the old-fashioned way? If you said yes, I'll bet it's because RPG CHAIN, SETLL, READE, etc. are easier and less hassle than trying to unscramble the proper use of statements, prepared statements, host variables, return codes, and all the rest. |

Coding SQL within RPG can be tedious, but what if you could automatically generate SQL for RPG, SQL for Java, and SQL for PHP in a just few clicks? by Scott Salisbury Have you ever avoided using SQL in your RPG programs because embedded SQL is a hassle and it's just easier to do it the old-fashioned way? Have you ever wished your RPG programs could access data from Microsoft SQL Server or Oracle? Do you work with multiple databases and multiple SQL client tools? What about Java and PHP? Both use embedded SQL. Are you using them yet? SQL(snap) simplifies SQL tasks and turns hours into a few clicks. |
