sql server - which kind of record this like will get? -

- 

like ',%,%,'

i using above in case statement record. it's not working expected.

my query - 

select   case          when row_id ',%,%,'             'a'         when row_id not ',%,%,'             ''         end 'af'         myview row_id = '2464,2465,2466'  order 1 desc

expected output - getting blank.

this like:

row_id ',%,%,'

will match every single row_id starts , ends comma , has @ least comma in between.

your query, because of clause

where row_id = '2464,2465,2466'

will return empty set because row_id doesn't match previous pattern.
