Question

Hi i need to control if my value is exists in a comma seperated list.

For example

DECLARE @list NVARCHAR = '6,3,67,34';

SELECT Column1, Column2 FROM Table1
WHERE PATINDEX ('%' + CONVERT(NVARCHAR, Table1.ID) + '%', @list)

It should return rows which ID field is 6, 3, 67 or 34.

How can i do with or without PATINDEX?

Answer 1

Add leading and trailing commas to both @list and Table1.ID in the search:

SELECT Column1, Column2
    FROM Table1
    WHERE CHARINDEX(',' + CONVERT(NVARCHAR, Table1.ID) + ',', ',' + @list + ',') <> 0;
