MS sql server text column to 8.0.5 CLOB

Question

my env: MS SQL SERVER (6.5 and 7.0) Oracle 8..0.5/8i
I have a 'products' table a sub-definition of which is:
MS sql server definition
create table products(
productid int IDENTITY(1,1) not null
,name varchar (255)
,description TEXT)
Oracle8 definition
create table products(
productid number(10) not null
,name varchar2(255)
,description CLOB)
My question is:
In sqlserver I have a query:
SELECT productid, name FROM products
WHERE products.description LIKE '%some text%';
The above query works in sqlserver but the equivalent query in
Oracle does not work i.e. I get the following error
ORA-00932: inconsistent datatypes
The error description does not fully explain my situation.
I want to confirm that I cannot have as part of my 'WHERE CLAUSE'
a reference to a 'CLOB' column i.e.
'WHERE clob.column LIKE '%SOME TEXT%'. If I cannot do this, how
else can I do it (without using Oracle's Context/Intermedia
option) or am I doing something incorrectly.
Your valuable suggestions/comments are most appreciated.

Answer 1

It may also be useful for you to take a look at the Intermedia
documentation.
And finally, Oracle Development say they are currently looking at
implementing LIKE for Clobs in future releases.
