Re: SQL query results in CPI432F

Dennis,

<QUOTE/>

the value of the right side of the expression (:COMP) should be equal or

less in length to the one of the left side (TCER). If not, a

table scan would ensue.

Whew!! I knew I had read that somewhere!! After days (not really) of digging
my old ref files, I found that info in an old Centerfield newsletter. Check

Elvis (Budimlic) if you are reading this, What happened to the newsletter?
We need fresh issues!! :-)

Interesting. But in this case, :COMP was of the same length (3, fixed) as
the table column. I'll have to read up on what you reported; sounds
interesting.
