Hi,
-------------
Declare @l1 varchar(10)= '4,5'
Select
Col1,
Col2
From
<tableName>
Where
Col3 in (@l1)
-----
Col3 is an integer value
This is showing error as "Conversion failed when converting the varchar value '4,5' to data type int."
What I needed was
---
Select
Col1,
Col2
From
<tableName>
Where
Col3 in (4,5)
--------
Any ideas about how to pass the argument?

Use this condition

WHERE ',' + @l1 + ',' LIKE '%,' + CAST(Col3 AS varchar) + ',%'

You can use a split function to parse the comma delimited list into a temp table and then use that in your query.

The function on the link below should do the job.

can cause performance hit in case of large datasets. Also in case Col3 contain spaces or other characters that has to be handled as well
