Info

It is recommended that you keep your SQL operations through these activities as simple as possible.

Note: LANSA Composer does not guarantee that any form of SQL statement that is valid for your target database can successfully be executed through the SQL database activities, nor that every form of SQL stored procedure can successfully be executed.
Nor will it be possible to successfully address every possible data type in your database.  Since processing sequence variables that might be used to pass or receive data to the SQL database are untyped, not all conversions can be successful or yield useful results.  It is your responsibility to ensure that any data passed through the SQL database suite of activities is in a form that can be accepted and processed by both the JDBC driver and the target database.

...

In any event, to maximize the benefit of LANSA Composer's restart capability, you should complete your SQL database operations and execute the SQL_DISCONNECT activity at the earliest opportunity. Once the SQL database connection has been closed, normal restart eligibility resumes.
