Question

I have two columns in my Table called as Workers – Technicians. In Workers I have name of workers, and in Technicians I have name of technicians who is working in company. Here is how it looks:

Workers                              Technicians

Andy                  Kevin
Conan                 Jason
Jay                   Ray
Donald                Daryl
Martin                .
Mark                  .(rows goes on)
.
.(rows goes on)       

What I want to do is to append these rows and having a column called Employees. Here what i want:

Employees

Andy                  
Conan                 
Jay                   
Donald               
Martin                
Mark
Kevin
Jason
Ray
Daryl
.
.

I don’t want to create another table, I just want to add a new column. How would i do this?

Answer 1

I also don’t understand fully what you want to do (mainly because of this: if, say, a row has “Andy” in Workers and “Kevin” in Technicians, what will you put in Employees? Andy or Kevin?), but to add a new column to the table and then fill it with data you need to:

1. Add it (assuming your table is named Table and 100 chars are enough for the new column):

   alter table [Table] add [Employees] nvarchar(100) null

2. Fill it:

   update [Table] set [Employees] = [Workers]

   — or:

   update [Table] set [Employees] = [Technicians]

I believe what you really want is a new table, Employees, and to change the Workers and Technicians into relationships drawn from it. For that, see the link Simon gave you about database normalization.
