I have the following SQL query. I need to write a case statement that converts LOBtotal which is an int field to a negative number when it is positive and a positive number to negative. I am not certain how to do this.

SELECT LOBTOB
            ,LOB_LOB
            ,BatchID = 'IS4WPAWP'
            ,DocNbr = 'CUEPrem'
            ,[Account Nbr] = CASE
                                           WHEN LOB_LOB = 'CM' THEN '01-5100-00CM00-010000-00'
                                           WHEN LOB_LOB = 'OC' THEN '01-5100-00OC00-010000-00'
                                           WHEN LOB_LOB = 'GL' THEN '01-5100-00GL00-010000-00'
                                           WHEN LOB_LOB = 'Tails' THEN '01-5100-00TL00-010000-00'
                                           WHEN LOB_LOB = 'Mini-Tails' THEN '01-5100-00MTL0-010000-00'
                                           WHEN LOB_LOB = 'Claims Made Plus Prepaid Tail' THEN '01-5100-00PTL0-010000-00'
                                           WHEN LOB_LOB = 'Adjustment' THEN ''
                                          
                                      END
            ,LOBtotal
            ,[Description] = CASE
                                           WHEN LOB_LOB = 'CM' THEN 'CM CUEP'
                                           WHEN LOB_LOB = 'OC' THEN 'OC CUEP'
                                           WHEN LOB_LOB = 'GL' THEN 'GL CUEP'
                                           WHEN LOB_LOB = 'Tails' THEN 'TL CUEP'
                                           WHEN LOB_LOB = 'Mini-Tails' THEN 'MTL CUEP'
                                           WHEN LOB_LOB = 'Claims Made Plus Prepaid Tail' THEN 'PTL CUEP'
                                           WHEN LOB_LOB = 'Adjustment' THEN ''
                                          
                                      END
                              
FROM dbo.LOB
WHERE lobtob = 'Direct Written'

0 - LOBtotal

If LOBtotal = 5
0 - 5 = -5

If LOBtotal = -5
0 - - 5 = 5 (two minuses = a plus)
0

How would that look with the case tag wrapped around it. I apologize in advance for my ignorance.

LOBtotal isn't in the CASE statements, it's on its own.

SELECT LOBTOB
             ,LOB_LOB
            ,BatchID = 'IS4WPAWP'
             ,DocNbr = 'CUEPrem'
            ,[Account Nbr] = CASE
                                            WHEN LOB_LOB = 'CM' THEN  '01-5100-00CM00-010000-00'
                                            WHEN LOB_LOB = 'OC' THEN '01-5100-00OC00-010000-00'
                                            WHEN LOB_LOB = 'GL' THEN  '01-5100-00GL00-010000-00'
                                            WHEN LOB_LOB = 'Tails' THEN '01-5100-00TL00-010000-00'
                                            WHEN LOB_LOB = 'Mini-Tails' THEN  '01-5100-00MTL0-010000-00'
                                            WHEN LOB_LOB = 'Claims Made Plus Prepaid Tail' THEN  '01-5100-00PTL0-010000-00'
                                            WHEN LOB_LOB = 'Adjustment' THEN ''
                                           
                                      END
             ,0 - LOBtotal
            ,[Description] = CASE
                                            WHEN LOB_LOB = 'CM' THEN 'CM CUEP'
                                            WHEN LOB_LOB = 'OC' THEN 'OC CUEP'
                                            WHEN LOB_LOB = 'GL' THEN 'GL CUEP'
                                            WHEN LOB_LOB = 'Tails' THEN 'TL  CUEP'
                                           WHEN LOB_LOB =  'Mini-Tails' THEN 'MTL CUEP'
                                            WHEN LOB_LOB = 'Claims Made Plus Prepaid Tail' THEN 'PTL  CUEP'
                                           WHEN LOB_LOB =  'Adjustment' THEN ''
                                           
                                       END
                             
FROM  dbo.LOB
WHERE lobtob = 'Direct Written'

Either as above or multiply the LOBtotal by -1.

CASE statement is not needed, just  (LOBtotal*-1) AS LOBtotal
0

This would also do:

,-LOBtotal
