Re: Select/Update Loop in SQL

Check out the WHERE CURRENT OF clause in the SQL Reference, for UPDATE and DELETE

https://www.ibm.com/support/knowledgecenter/ssw_ibm_i_73/db2/rbafzupdt.htm

Also, consider the use of the FOR UPDATE OF clause on the SELECT statement, to limit which columns are affected.

What's the best way to update a row after it's read and processed in a SQL
Loop? Can I just do an update in the loop?

EXEC SQL DECLARE CURSOR C
DOW SQLSTT = 00000
EXEC SQL FETCH NEXT
EXEC SQL UPDATE?
EXEC SQL FETCH NEXT
ENDDO

Thanks
