INSERT WHERE NOT EXISTS

DG
Hi,

I'm trying to insert some data into a table and wish to confirm the insert
is good rather than creating an error. I have tried the following (which
works on Sybase)

INSERT customers
(full_name)
VALUES
(''Big Tech Enterprises')
WHERE NOT EXISTS ( SELECT c.*
FROM customers c
WHERE c.full_name = ''Big Tech
Enterprises')

Can anyone advise the correct syntax for MySQL?

Much appreciated,

David

Make the c.full_name a unique index and use "INSERT IGNORE ..."
