The source member type for these programs is SQLRPGLE. Instead you'd need to use VALUES (SELECT * from MYTABLE) into :myData which can be run dynamically. The condition in the loop is somehow dependent on Here is an example of using dynamic SQL in ILE RPG. This example program is written in the ILE RPG programming language.

Straight-Up RPG Without Embedded SQL For our RPG code without embedded SQL, we will chain into the EMPLOYEE file to retrieve the employee name, and then we will loop through SQL in RPG Free June 18, 2020, 01:59 PM Hi, I am new to the forums so please bear with me about my question. However, you'd be better off using a SELECT INTO with FETCH FIRST ROW ONLY if you know you only need 1 row There are many interactive RPG programs that perform data selection based on input parameters from a display file. Note normally you'd see the FETCH in a loop to return multiple rows, as written this will just return the first row then end.
