is used to create bind parameters in ColdFusion SQL statements. For to work the DBMS and drivers must support this feature (most good DBMS’s, including SQL Server and Oracle, do). ColdFusion will try to automatically detect their support and degrade the query as necessary. But as a rule you should not rely on this. Check your DBMS’s docs, and only use if bind parameters are supported (or change your DBMS if they are not). (Applies to: ColdFusion 4.5 or later)
