Searching for Comma-Separated Values in MySQL

Encounters with tables containing comma-separated lists as references to other tables are not uncommon. These situations, while acknowledged as unfavorable, pose challenges when attempting to search within the field using a LIKE query.

When attempting to search for a specific value, using a LIKE query like '%1%' can result in numerous positive matches due to the prevalent range (10-20) in which these IDs reside. To address this, one might consider searching for matches as %,1,%. However, this approach fails to account for IDs at the start or end of the list.

A viable solution involves utilizing the FIND_IN_SET function, which enables users to search for a value within a comma-separated field. By employing FIND_IN_SET('1', field), the query identifies records that contain the value '1' in the field. This function effectively resolves the issue of searching for specific values in comma-separated lists and enhances the accuracy of database queries.
