Subquery returned more than 1 value. This is not permitted when the subquery follows =, !=, = or when the subquery is used as an expression.

IF (
select  COUNT(*) AS COUNT  from(select distinct SUBSTRING(LandRiverSegment,7,19) as riverseg,CBSegid from wsmpv24Reporting.dbo.TblLandRiverSegment
) as a
group by riverseg

when i run this individually it is showing the count ,---2

but when this part is kept in a Cursor it throws eror
