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

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
