It returns results even though i specify a so called empty string to the stored proc.How should i prevent returning result when is empty? Thanks a lot here is my code:Create proc TestEmployee_Search@searchnameemail as nvarchar(50)asSet NoCount OnSELECT [FirstName]      ,[LastName]      ,[Email]  FROM [dbo].[Account]  where '' + ([FirstName] + ' ' + [LastName] + ' ' + [Email]) + '' like '%' + '' + @searchnameemail + '' + '%'Exec TestEmployee_Search '' |
