I've basically copy + pasted the formula and generated this error code. Any idea?

Disregard, simply added customer_id within the ( ) and added a dummy value.

Hi! I have error when I added Insert into. What should I do next ? Thank you in advance.

Hi Manap! Thanks for reaching out. Please, add a semi-colon (;) after the insert query. This is the cause of the error. Hope this helps. Best, Tsvetelin

Don't put a dummy value, the reason it's not working is you need to have dropped the previous customers' table and rewrite the column customer_id with AUTO INCREMENT so that it auto-fills the values of that customer_id section.

Hi Roy! Thanks for reaching out. Thanks for sharing this piece of information with the Community! The cause of the error is because of the missing semi-colon (;) after the insert query. Hope this helps. Best, Tsvetelin
