Using a comma-separated parameter in an IN clause

Question

I have \'param1, param2, parma3\' coming from SSRS to a stored procedure as a varchar parameter: I need to use it in a query\'s IN cla

Answer 1

If you are using SQL 2016 and above string_split you can use.

-- @param is where you keep your comma separated values example: 
declare @param = 'param1,param2,param3'
select * from table1 where col1 in (select TRIM(value) from string_split(@param,',')

More information about string_split check offical documemt

Furthermore, TRIM() is used to trim values from white spaces.
