I have two tables that I want to join. The problem is, the data needs some trimming.

== Product Description

id              sku                 price

1               674_orange          45.99
2               645_black           59.99
5               592_rubyred         69.99

== Product Attributes

id          sku     description

11          674     lorem ipsum long text description of 674
22          645     lorem ipsum keywords for this item
33          592     lorem ipsum colours on this item

I want to join these tables on the SKU. However I need to do a replace since I don’t think a LIKE or % would be accurate enough?

    Use

    select *
from description d
join attributes a on a.sku = substring(sku, 1, locate('_', sku)-1)

    locate('_', sku) gets the position of the _ in your string

    substring(sku, 1, locate('_', sku)+1) extracts a substring from sku. The substring will start at position 1 and end at the position before _. That is why -1 is used.
