Question

Is there a way to do the following:

DECLARE @startVal integer

SELECT 
    @startIdx = MAX(Range_val) 
FROM 
    [Bookings].[dbo].[Range] (nolock)

INSERT INTO
    [Bookings].[dbo].[Range]
VALUES
    (INCR(@startVal), 'someVal', 'someOtherVal'),
     (INCR(@startVal), 'someVal1', 'someOtherVal3'),
     (INCR(@startVal), 'someVal2', 'someOtherVal4'),

Where INCR() is some function that increments the variable. Instead of doing ‘@startIdx + 1’, ‘@startIdx + 2’, etc?

EDIT: This is not necessarily the table index. I know I can drop the table and recreate it the proper way (assuming this is the index), but that’s not my question. Is there a way to increment a variable the way I have described?

If your just looking to make it easier to mess around with & cannot use an
identity column here are a couple of ways to avoid specifying +1;

   declare @T TABLE (idx int identity(1, 1), f1 varchar(128), f2 varchar(128))
   insert into @T values
       ('someVal',  'someOtherVal'),
       ('someVal1', 'someOtherVal3'),
       ('someVal2', 'someOtherVal4')
   insert [Bookings].[dbo].[Range]
       select @startIdx + idx, f1, f2 from @T

Or (ids are assigned in an alphabetical not ordinal order based on the 1st
field)

   insert [Bookings].[dbo].[Range]
      select @startIdx + row_number() over(order by name1) as n, *
          from (
                  select top 0     '' as name1, '' as name2 --header
                  union all select 'someVal',   'someOtherVal'
                  union all select 'someVal1',  'someOtherVal3'
                  union all select 'someVal2',  'someOtherVal4'
          ) T

Are you sure you want nolock?
