I am very new to SQL Development, so I want to apologize in advance if the question is weak. Here is what I am looking to do....I have a table with data in it but it has one empty column (LastColumn). What I am trying to achieve is see if data in first column (column1) is a positive or a negative. If its positive then add some string (somestring) to join it with data in another column(Column2) and insert the cojoined data in LastColumn.
Column1 is int
Column2 is nvarchar
LastColumn is nvarchar

Eg... if data in column1 = -2 and data in column2 = ABC then i should ne able to insert -2ABC in LastColumn.

What would be the best approach to do this...stored procedure??

do you mean this?


UPDATE Table
SET LastColumn=CASE WHEN column1 <0 THEN CAST(column1 AS varchar(10)) + column2
                    ELSE 'somestring' + column2
               END
