Question

I am on Oracle 10g. In a requirement I need to increase the size of a pl/sql VARCHAR2 variable. It is already at 4000 size. I have read that

in PL/SQ

Answer 1

Not sure what you meant with "Can I increase the size of this variable without worrying about the SQL limit?". As long you do not try to insert a more than 4000 VARCHAR2 into a VARCHAR2 SQL column there is nothing to worry about.

Here is the exact reference (this is 11g but true also for 10g)
