Hi,
Scenario:
I have a "bulk collect into" statement inside a cursor. The syntax is correct and the pgm is working. But it is slow because I am processing 1.5 million rows. The bulk collect populates say 10 array each with 1.5 million rows. Using a For loop I then parse through the entire length of the array and update values for some of these 10 columns values. After the for lop I have a FORALL bulk update statement. For such a large number of rows, Oracle needs a huge rollback segment for the update.
Question:
Can I have a limit on the bulk collect to say 3000 rows. I bulk collect 300 rows into the 10 arrays, process them , do a bulk update for the 300 rows and then fetch the next 3000 rows until the 1.5 million rows are processed? I am trying to find examples of this but am unable to? Thanks in advance
