Trying to insert some data:
INSERT INTO `ps_product_check`(`id_product`, `name`, `catalog`)
VALUES (30767,'CT39-235126','79926330')
The error is
#1054 - Unknown column 'CT39' in 'field list'
Why does it think CT39 is supposed to be a column when it is (a part) of a value? How to get around this error?
I run your query and it works very fine.
INSERT INTO `ps_product_check`(`id_product`, `name`, `catalog`)
VALUES (30767,'CT39-235126','79926330')
It is possible that you have placed other quotes (backticks) in the query executed.
If I change the quotes like
INSERT INTO `ps_product_check`(`id_product`, `name`, `catalog`)
VALUES (30767,`CT39-235126`,'79926330')
I get the same error.
