RE: MSSQL Stored Procedures Call

[Justin Taylor <JUSTIN@xxxxxxxxxxxxx>]

The issue is JVM startup times.  If you want to use JDBC directly out of an IBMi client job, that job has to start the JVM, which takes time.  If you have a common job that does all the JDBC access, the JVM startup is only for that job, and not for every client.

Of course, if your IBMi client jobs run for a long time, the one-time JVM startup time might not be as much of an issue.

Ok I think I slightly misunderstood the question

RPG ODBC calls would probably be faster, but I don't know RPG. Starting a python script in PASE would also be fast. There is pymssql and you can use pyodbc with freetds as well. A php script called from QSH would also work.
Either language would not have a big startup window, and can talk to MSSQL

Ok I'm a little murky on the greenscreen side of things hence my weird reply.
