I think what's wrong is probably the last parameter which should be $1 not
just 1.
The other thing is that what you may need is to remove the characters, so
you should put a caret character before a set l[A-za-z]'.

Regex is not difficult but tricky you have to play a while to get what you

Our system is running IBM i 7.3 with the latest PTF's and TR's (PTF's and
TR's installed in the last 2 weeks).

Jerry Ven recently asked questions about extracting the numeric values
from a character field to use as a key for joining the file to another
file which has a numeric key.

I believe that someone had suggested using the SQL REGEXP_REPLACE scalar

Searching for examples, I found this:


which gave the following example:

'123Red345', '[A-Za-z]','',1)
FROM sysibm.sysdummy1

indicating that this statement should return the value '123345'.

However, when I run this SQL statement it returns the value

What gives?
