Shorten SQL update query

Is there a way to shorten this update query? I'm new to this and not sure how can I further shorten it

UPDATE [Tbl_SS_Utilization(F03)_Copy1]
SET [WW0] = 0
WHERE [WW0] IS NULL

UPDATE [Tbl_SS_Utilization(F03)_Copy1]
SET [WW0+1] = 0
WHERE [WW0+1] IS NULL

UPDATE [Tbl_SS_Utilization(F03)_Copy1]
SET [WW0+2] = 0
WHERE [WW0+2] IS NULL

UPDATE [Tbl_SS_Utilization(F03)_Copy1]
SET [WW0+3] = 0
WHERE [WW0+3] IS NULL

UPDATE [Tbl_SS_Utilization(F03)_Copy1]
SET [WW0+4] = 0
WHERE [WW0+4] IS NULL

UPDATE [Tbl_SS_Utilization(F03)_Copy1]
SET [WW0+5] = 0
WHERE [WW0+5] IS NULL

I don't know what RDMBS you're using, but your posted SQL looks like T-SQL (for Microsoft SQL Server or Sybase), in that case then this single UPDATE statement should do the trick:

UPDATE
    [Tbl_SS_Utilization(F03)_Copy1]
SET
    [WW0]   = CASE WHEN [WW0]   IS NULL THEN 0 ELSE [WW0]   END,
    [WW0+1] = CASE WHEN [WW0+1] IS NULL THEN 0 ELSE [WW0+1] END,
    [WW0+2] = CASE WHEN [WW0+2] IS NULL THEN 0 ELSE [WW0+2] END,
    [WW0+3] = CASE WHEN [WW0+3] IS NULL THEN 0 ELSE [WW0+3] END,
    [WW0+4] = CASE WHEN [WW0+4] IS NULL THEN 0 ELSE [WW0+4] END,
    [WW0+5] = CASE WHEN [WW0+5] IS NULL THEN 0 ELSE [WW0+5] END
WHERE
    [WW0]   IS NULL OR
    [WW0+1] IS NULL OR
    [WW0+2] IS NULL OR
    [WW0+3] IS NULL OR
    [WW0+4] IS NULL OR
    [WW0+5] IS NULL

Or with COALESCE (or ISNULL if you're feeling brave):

UPDATE
    [Tbl_SS_Utilization(F03)_Copy1]
SET
    [WW0]   = COALESCE( [WW0]  , 0 ),
    [WW0+1] = COALESCE( [WW0+1], 0 ),
    [WW0+2] = COALESCE( [WW0+2], 0 ),
    [WW0+3] = COALESCE( [WW0+3], 0 ),
    [WW0+4] = COALESCE( [WW0+4], 0 ),
    [WW0+5] = COALESCE( [WW0+5], 0 )
WHERE
    [WW0]   IS NULL OR
    [WW0+1] IS NULL OR
    [WW0+2] IS NULL OR
    [WW0+3] IS NULL OR
    [WW0+4] IS NULL OR
    [WW0+5] IS NULL
