Microsoft® Access SQL supports the use of the ODBC defined syntax for scalar functions. For example, the query:

SELECT DAILYCLOSE, DAILYCHANGE FROM DAILYQUOTE WHERE {fn ABS(DAILYCHANGE)} > 5

Would return all rows where the absolute value of the change in the price of a stock was greater than five.

A subset of the ODBC defined scalar functions is supported. The following table lists the functions that are supported.

For a description of the arguments and a complete explanation of the escape syntax for including functions in a SQL statement, see the ODBC documentation.
