Question

I have a field in tables, with datatype “set” so that it can accept multiple values. But I got stuck at the time, when I am retrieving the results matching values to it.

An Example field

"menuPosition" : set('top','left','right','bottom')

An Example query

SELECT * FROM mytable where menuPosition='top'

This query only returns those rows with only top as their values, the rows having multiple values like top,left are not returned. How to retrieve all those records?

And since my above query only compares one values, how to write a query to match multiple values like where menuPosition='top' && 'bottom'

Answer 1

You caeither use FIND_IN_SET like:

SELECT * FROM mytable WHERE FIND_IN_SET('top', menuPosition)

Or you can use LIKE:

SELECT * FROM mytable WHERE menuPosition LIKE '%top%'

I guess the first one is faster.
