How to add data to a column of existing data

[jdoolittle]

I need to categorize 35,000 cells of data in a column into 3 different groups (A,B, and C). Each cell will have something like "G00001" or "G00525" in it, but depending on when it was added, I want to change it to "G00001A" or "G00525C". I created a select query to show only the G0000's column and the column that indicates AB or C, but i don't know how to add the letters at the end of my G0000's. Do I need to use an update query or can I do something more simple? Also, if I need to use an update query, how would I build it to do what I need to get done?

You can simply concatenate them. In a query for instance:

NewColumn: FirstColumn & SecondColumn
