SQL 2008 :-

In my Table :TableName,  i have 3 columns [Ship Qty], Size, Qty.

Default value for Qty  is NULL. I wrote an Update Query to update the column : Qty. I need to multiply [Ship Qty] * Size.

Column : Size is nvarchar. It carries two conditons

1) If the value is 60 EA or 3 ML, I need to consider only 60 or 3 or 3.5 ...
2) If the value is 60X3 ML, I need to consider 60X3 which is 180. Then, this multiplied value will be multiplied with [Ship Qty].


Ship Qty    Size             Qty
1           100 EA           100
3           60 EA            180
2           60X3ML           360
update [TableName] set Qty = [Ship Qty] * CONVERT(INT, (Size)) * CONVERT(Float, (Size))                 WHERE  Size > 0                     AND Size > 0                     AND Qty IS NULL

      (case TN.size
            when '100 EA' then 100
