Mapping A String Field To Boolean Output In SELECT Clause

Hello,
I am facing a problem in a SELECT clause which i cannot solve.
In my SQL table ("myTable") i have a few columns ("Column1", "Column2", "TypeColumn"). When I select different columns of the table, instead of getting the value of TypeColumn, i would like to get a boolean indicating whether its value is a certain string or not.
For example, the TypeColumn accepts only a number of selected strings: "AAA", "BBB", "CCC".
when i do a select query on the table, instead of asking for TypeColumn i would like to ask a boolean value of 1 if TypeColumn is "AAA" and 0 if TypeColumn is "BBB" or "CCC". Also, i would like to make this query while I am also fetching the other columns. And i would like to use one query to get all that. I thought something like thsi would work:

SELECT Column1 AS Col1, Column2 AS Col2, IF(TypeColumn = "AAA", 1, 0) AS Col3
FROM myTable

but this doesn't work in SQL 2005!
Is it possible to do something similar in SQL 2005 using one query only? i am trying to avoid multiple queries for this.

thanks a lot for your help!
