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.
