Hi, Baharin,
As Mahesh said, WHERE only works on a query.
You can always base a query on dual, like this:
INSERT INTO
tdc_imarspc (ANUMBER,     EMF_ID,     PRODUCT)
SELECT          '1234567',     '65',     'ITFS'
FROM         dual
WHERE          anumber      NOT LIKE '1234567';Of course, you can use a literal, like '1234567' in both places where I used the bind variable, but if you're not using a variable, why would you want to?
You could also put all the literals in a sub-query (based on dual), and reference column names in the main WHERE clause, LIKE THIS:
INSERT INTO
tdc_imarspc (     ANUMBER,     EMF_ID,          PRODUCT)
WITH     sub_q
AS  (
    SELECT    '1234567' AS an,     '65' AS ei,     'ITFS' AS pr
    FROM      dual
SELECT          an,          ei,          pr
FROM     sub_q
WHERE      an      NOT LIKE '1234567'; 
I assume you're not really saying
an      NOT LIKE '1234567'If you're not using any wild cards after LIKE, you might as well use !=
an      != '1234567'
