Hi,
If we have table with clob column and want to findout whcih clob column rows has been updated/inilialised thru empty_clob() functions? How to do that?

Like table with 2 columns ID and testcolu .ID is desc test_table

Name                                                              Null?

Type
----------------------------------------------------------------- --------

ID NUMBER(16)

TESTCOLU                                                             CLOB

Having rows like

ID TESTCOLU

         1 aaaaaaaa
         2 aaaaaaaa
         3
         4
        99

Out of these 5 rows id# 4 were inilialised thru EMPTY_CLOB() function.Wondering which sql statement would pickup only those rows having id value 4 .
The ID 3 was inilialised thru NULL and 99 was with ' '. thanks in advance.
