如何搜索完全匹配

Question

I am using Rails 4, a MySQL database, and jQuery Datatables 1.10. I have a search function that works, but returns more results than I'd like.

For example, when I search for "Phase I" it returns results with the fields "Phase I", "Phase II", or "Phase III" because "Phase II", and "Phase III" both contain "Phase I".

This is the Query:

table = table.where("col_name like :search", search: "%#{query}%")

How can I change this search to only return "Phase I" and not "Phase II" or "Phase III"?

Answer 1

Your query would be

Table.where(col_name: query)

That should give you an exact match

Answer 2

此解决方案为我工作：

table = table.where("col_name = '#{query}'")
