Below is the list of tables from the database along with their columns and datatype. Need to generate an accurate SQL query for the question.
Only use the columns present in the respective table. Only use the columns which are required to generate the SQL query. Only use table joins if required and not otherwise.

### Tables ###
TABLE: CREATE TABLE table_63080 ( "Rank (2012)" real, "Rank (2010)" real, "Employer" text, "Industry" text, "2012 Employees (Total)" real, "2010 Employees (Total)" real, "2007 Employees (Total)" text, "Head office" text )

### Question ###
What shows for 2010 Employees (Total) when the employer is University of Alberta?

### Accurate SQL ###

SELECT SUM("2010 Employees (Total)") FROM table_63080 WHERE "Employer" = 'university of alberta'
