I need to write a SQL update query. I want to update where workorder=12300000

  • 0

I need to write a SQL update query. I want to update where workorder=12300000 column1.TrimStart(B7CL).Addto(column2). But how can I do that in SQL Server 2005?

Convert this table:

workorder |column1            | column2         
12300000  |B7CL-B32-41-00-5A  | NULL
12400000  |B7CL-B33-42-00-5A  | NULL
12300000  |B7CL-B34-44-03-5A  | NULL
12600000  |B7CL-B35-45-01-5A  | NULL
12300000  |B7CL-B36-45-01-5A  | B36-45-01-5A

To this table:

workorder |column1            | column2
12300000  |B7CL-B32-41-00-5A  | B32-41-00-5A
12400000  |B7CL-B33-42-00-5A  | B33-42-00-5A
12300000  |B7CL-B34-44-03-5A  | B34-44-03-5A
12600000  |B7CL-B35-45-01-5A  | B35-45-01-5A
12300000  |B7CL-B36-45-01-5A  | B36-45-01-5A

    Set Column2 = Replace(Column1, 'B7CL-','')
    Where Column2 Is Null
