In this working example, we establish an SQL table which contains the spreadsheets we'd like to have generated. Each row in the table includes the query that will supply the data for the spreadsheet, and the location in the IFS where the spreadsheet should reside. Further, a different procedure emails the spreadsheets to an interested consumer. …

-- Setup:
-- 1) create and populate the spreadsheet generator table
-- 2) change the procedure source code:
-- 2a) Use ACS to upload acsbundle.jar to /home/acs/acsbundle.jar
-- 2b) Change forstie@us.ibm.com to your email address. <==== Please don't email me your spreadsheets :)
-- 2c) Change /system=COMMON1 to use the name of your IBM i
-- 2d) Change the ADDUSRSMTP user profile to be your user profile

Ah. LPRINTF is limited to 1000.
IN PRINT_STRING VARCHAR(1000) CCSID 37
Is it possible that your string is > 1000?

Hello Scott,

Yes. Its bigger than 1000 but less than 5000. I think it is close to 1600.

When I try lprintf'ing a string longer than 1,000, I do not see the message in the joblog either, because a failure (-302) occurs on the call.
Maybe there's an SQL0302 message in your joblog.
I can look at extending the size of the lprintf string, if you think is worth doing so.

Yes. I see the -302 message too.

And my Vote for increasing the lprintf string size would be a YES. It will really help in debugging. Sometimes we do need to print and see long Strings like xml, json, email body text etc. And these kind of variable values can be long.

Ok, I'll extend it to 30,720. The message data will appear in the joblog 512 characters at a time. (max of 60 messages)

Sounds great. Thanks Scott. Appreciate it.

By when can we expect it to be part of a PTF?

You can have the improvement today.
I updated the script found here: https://gist.github.com/forstie/314dde2d3e32ef9b7b83495e6d620fff

I will get this in a PTF at some point, so that everyone has it by default.

Great. Thanks Scott.
