    Please get the basic book on data modeling and read it. An employee ID is an identifier; identifiers are never numeric because you don't do any math with them. This should be a character string, perhaps made of digits. In which case adding a "xxxxx-1" is a simple matter of and alter table and string concatenation.

  • use a simple string concatenation  to meet your requirement.

    for this you need to convert your int  field in to varchar and then perform concatenation.

    declare @id int
    set @id = 100
    select CONVERT(varchar(10), @id)+ '-1'
    select CONVERT(varchar(10), @id)+ '1'
    select CONVERT(varchar(10), @id)+ '2'

  • CONCAT (for 2012+) can also do it, your integer will be implicitly converted

  • Hi Sky,

    Per the title of the post, you mean to want this?

    declare @employeeID1 int
    declare @employeeID2 int
    set @employeeID1=1000
    set @employeeID2=1002
    select @employeeID1 as v1_1,@employeeID1*100+1 as v1_2,@employeeID2 as v2_1,@employeeID2*100+1 as v2_2

  • DECLARE @EmployeeID int = 1002
    SELECT STR(@EmployeeID,LEN(@EmployeeID)) + '-1'
    SELECT CONCAT(@EmployeeID,'-1')
