Microsoft Access SQL supports the use of the ODBC defined syntax for scalar functions in a pass-through query that runs on Microsoft SQL Server. For example, to return all rows where the absolute value of the change in the price of a stock was greater than five, use the following query:
SELECT DailyClose, DailyChange FROM DailyQuote
WHERE {fn ABS(DailyChange)} > 5For a description of the arguments and a complete explanation of the escape syntax for including functions in a SQL statement, see Scalar Functions.

CONVERT |
Note String literals can be converted to the following data types: SQL_FLOAT, SQL_DOUBLE, SQL_NUMERIC, SQL_INTEGER, SQL_REAL, SQL_SMALLINT, SQL_VARCHAR and SQL_DATETIME. To convert a string to currency, use SQL_FLOAT. For more information, see Explicit Data Type Conversion Function.
