Yeah, The readpe is only performed if there was a REPAIR found.

Subject: [EXTERNAL] Re: sql equivalent to chain and readpe

Well, that might be too simple actually, it doesn't prove you had a 'REPAIR'

What about

select status from file
where ID = 21489 and Type < 'REPAIR'
order by ID, Type, Date
fetch first row only

I am converting a rpg program that uses a chain, followed by a readpe
to retrieve a value.

I am converting this program to pull the same data from a sql server
table using Scott Klements jdbc methods.
I am looking at using the sql lag function, but that does not seem to
be what I need.

Data looks like the following

ID TYPE Date Status
21489 RECHECK 20180928 2
21489 REGRADE 20180418 2
21489 REPAIR 20190102 0

Key in file is ID,TYPE,Date

Chain looks for the REPAIR, then does a read prior equal on the ID to
get the previous status

Is there a way I can do the same thing using sql ?

Thanks

MIke
