The DB Access Module for Oracle OCI uses positional binding for binding program variables to the Oracle 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:

where anything can be a name or a number. For example, to insert data into a two-column table, named MyTable, through binding, the SQL statement would look like this:

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