Ok, so queries are not my bag baby

I need to know how to properly write an SQL Update query please. I have a table called zen_products_description and one of my categories is Bible covers. I want to do the following:

There are some Bible covers that contain Bible Cases open flat and feature in the description. I need to write an update query that says where the description contains Bible Cases open flat and feature, blank it out to say nothing. Does this make sense?

P.S. Here is what I tried - UPDATE zen_products_description SET products_description = ' ' WHERE products_description = 'Bible Cases open flat and feature'
