The DB Access Module for Sybase uses host-variable format for binding program variables to the Client-Library. When input parameter values are provided through binding for RWDBOSql objects, applications must use proper placeholder syntax in their SQL statements. The proper placeholder syntax for host-variable format is @something, where something must be a unique string among the placeholders within an SQL statement. For example, here is the SQL statement to insert data through binding into a 2-column table named mytable:

Placeholder syntax is not a portable feature. Different Access Modules use different placeholder syntax.
