Can I use SQL (in an AS400 environment) to update a substring of a field?
In this example, the update to the substring is conditional.
Follows is the SQL syntax I used and the error message I received:
update a04bsydtaa/bsyglgp set substr (lggl#,5,4) = '0010' where lghsp# = 999
Token ( was not valid. Valid tokens: =.
