You are right Scott, I can make this much easier.
But it is my first attempt at embedded SQL and I want to understand the
CURSOR method better.

When I do the changes and compile, I get this:

Record *...+... 1 ...+... 2 ...+... 3 ...+... 4 ...+... 5 ...+... 6 ..
10 C+ FOR UPDATE OF XXXPY70P
5761ST1 V6R1M0 080215 Create SQL ILE RPG Object PROS
DIAGNOSTIC MESSAGES
MSG ID SEV RECORD TEXT
SQL0206 30 10 Position 23 Column XXXPY70P not in specified table

Looks like it wants a field specified?

I SENT YOU AN EMAIL OFF YOUR WEB PAGE, DISREGARD THAT.

Nice to see though that on your web page you have your priorities correct on
your titles.
Family first.

Hi Tom,

On your declare cursor/select statement, you need "for update of
XXXPY70P"... for example:

C/EXEC sql
C+ DECLARE A CURSOR FOR
C+ SELECT *
C+ FROM XXXPY70P
C+ WHERE SUBSTR(DEDSC1, 68, 3) > ' '
C+ AND SUBSTR(DEDSC1, 70, 1) <> 'N'
C+ FOR UPDATE OF XXXPY70P
C/end-exec

And on the update, you need to use the filename -- NOT the record format
name. (You never use the record format name in SQL)

C/exec sql
C+ update xxxpy70p
C+ set dedsc1= substr(dedsc1,1,67)
C+ WHERE CURRENT OF A
C/end-exec

Though, I wonder if you really need to declare a cursor and all of that.
Do you need the fields in your RPG logic? If not, you can just do this:

C/exec sql
C+ update xxxpy70p
C+ set dedsc1= substr(dedsc1,1,67)
C+ WHERE SUBSTR(DEDSC1, 68, 3) > ' '
C+ AND SUBSTR(DEDSC1, 70, 1) <> 'N'
C/end-exec

Good luck

I am trying to do an update while in a loop with embedded SQL in RPG.

When I enable the update, SQLSTATE returns 24501 and nothing seems to be
put
in the buffer.

When disable the update, it runs fine.

I cannot find any examples of updating using embedded SQL.
I have the file format referenced in the UPDATE. I had the name of the
physical file.
Worked the same. I also tried using the name of the external data
structure,
same results.

Here is my code:

FQsysprt O F 120 PRINTER OFLIND(*InOF)
DPRODOCKE E DS EXTNAME(XXXPY70P)
C/EXEC sql
C+ DECLARE A CURSOR FOR
C+ SELECT *
C+ FROM XXXPY70P
C+ WHERE SUBSTR(DEDSC1, 68, 3) > ' '
C+ AND SUBSTR(DEDSC1, 70, 1) <> 'N'
C/end-exec
C/EXEC sql
C+ OPEN A
C/end-exec
C SQLSTATE Downe '02000'
C/EXEC sql
C+ FETCH A INTO :PRODOCKE
C/end-exec
C If sqlstate='02000'
C leave
C Endif
C/exec sql
C+ update xxxpy70f <<< when enabled, no
recs
end up in buffer
C+ set dedsc1= substr(dedsc1,1,67) CONCAT ' ' <<< disabled, prints
all
recs that qualify
C+ WHERE CURRENT OF A
C/end-exec
C** except print
C Enddo
C/EXEC sql
C+ CLOSE A
C/end-exec
C eval *inlr=*on
OQsysprt E print 2
O deccy
