Question : VBA SQL sysntax

This is my query:
sql = "SELECT STOCK.stCode, STOCK.stDescLine1, STOCK.stBarCode, Trim([stCode]) AS BC FROM Exchequer.BGCI02.STOCK STOCK "
sql = sql & "WHERE STOCK.BC = '" & ActiveCell & "'"

The StBarcode fiels has trailing spaces so I need to trim it but Excel returns "Trim is not a built in funtion"

Does anyone know how to acheive this?
