How can I check whether a number is contained in comma separated list stored in a varchar column?

Question

I have a table with a varchar column categoryIds. It contains some IDs separated by commas, for example:

id       categoryIds
-----         


        

Answer 1

SELECT * 
FROM myTable 
WHERE (',' + RTRIM(categoryIds) + ',') LIKE '%,' + @stringId + ',%'

Here @stringId is your text to be searched. In this way you can avoid unnecessary multiple where conditions
