You are not saying who is calling these stored procedures but have you
considered XML or JSON? lnput is text so you can send one to hundreds of
fields. You could build dynamic SQL statements to do the actual update or
insert or whatever.

I have in the past have loaded service programs dynamically and passed XML
to perform some action. I built a database table with an action name and
the name of the service program, library and procedure name to perform that
action so everything was dynamic.

We have some CRUD stored procedures and I am wondering how you guys handle
the Update part. We are using RPG. Creating a procedure with the input
parms of an action code 'CRT', 'UPD', 'DLT' and all of the columns to the
table. The CRT and DLT are easy. But the UPD. The caller may not know
all of the values of all the columns. They know the keys and the values
they want updated. How do you handle the values that are not to be
We came up with if the column is char if the value is a pipe change to
blanks if blanks no change. other values then change it. Same type of
thing with numeric values -99999999 = zero, zero no change other values
then change.
For a small table this is okay but you get a table with 25+ columns, what a
programming pain on both sides.

Is there a better way?
