MYSQL Updating multiple columns using variables

Question

I used this query to insert all my values into this database:

INSERT INTO products ($fields) VALUES ($values)

However, I try to use the same format for UPDATE:

UPDATE products SET ($fields) VALUES ($values) WHERE sku = '$checksku'

...and am getting thrown a syntax error:

You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near '('product,make,model,' at line 1

I can't figure it out. Would appreciate any help. Thanks.

Solution 1

UPDATE syntax is different than INSERT syntax. An example of UPDATE would be:

"UPDATE products SET field1 = 'value1', field2 = '$val2', field3 = 5 WHERE sku = '$checksku'"  

Though this may be insecure. You should look into parameterized queries.

Solution 2

INSERT INTO products ($fields) VALUES ($values) ON DUPLICATE KEY UPDATE field = VALUES(field), ...

Don't forgot about unique or primary key

I basically ended up using this, just disappointed that I had to do it 23 times (amount of fields)

This is not valid MySQL syntax.
