Question

I have a stored procedure that has this line:

SET @SQL = 'SELECT path,title,tags
            FROM (
                  SELECT ROW_NUMBER() OVER(ORDER BY file_number) AS Row, *
                  FROM  files) AS tbl 
            WHERE file_number IN (SELECT tag_file_number 
                                  FROM tags 
                                  WHERE tag LIKE ' + @Conditions + '), Row >= '
                   + CONVERT(varchar(9), @StartIdx) + ' AND
                   Row <= ' + CONVERT(varchar(9), @EndIdx)

I get an error when I pass ‘bus’ as a parameter value. My objective is to pass a piece of SQL query and substitute it in the place of @conditions.

I may also pass ‘%bu% or tag Like %time% or tag Like %bus time%’ I think this is not hard to do but I simply can’t figure it out. It’s a very specific problem, therefore I can’t even google it up. Please help me. Let me know if you need any more information.

You are missing the quotes, try it like this:

SET @SQL = 'SELECT path,title,tags
        FROM (
        SELECT  ROW_NUMBER() OVER(ORDER BY file_number) AS Row, *
              FROM  files ) AS tbl WHERE file_number in(select tag_file_number from tags where tag like "' + @Conditions + '"), Row >= '
                            + CONVERT(varchar(9), @StartIdx) + ' AND
               Row <=  ' + CONVERT(varchar(9), @EndIdx)

Now what’s happening is where tag like bus and it must be where tag like "bus".
