I have a task to fix some rather strange RPG IV code that was written over 20 years ago which appears initially to be a set of fairly typical Display File screens with subfiles and options to access detail records (2=Change, 4=Delete, 5=Display, etc.). However in the background, some never-ending batch...

I successfully use http_get() to retrieve documents from a web service of up to 4Mb and store them on the IFS using ifs_write(). Unfortunately, some of the documents requested are larger than what RPG allows (~16Mg if I remember).

I was wondering if I can skip over the need for a host variable...

Once I try to use the clob variable inside the SQL statement I get the error below.

Hello all,

I'm puzzled why REGEXP_COUNT returns weird results, for example take this query:

select regexp_count('1','[A-Z]')
from SYSIBM.SYSDUMMY1 

Regular expression [A-Z] means it accepts a letter from A to Z. But 1 is no letter, and the result of...

The system defined default value for a date column in DB2/iSeries is always "current date". How can we change that to '01/01/0001' (*LOVAL) ?

When I insert a record via RPGLE, the date fields always default to *LOVAL.
Whereas, when I insert a record using SQL (or an ETL...
