Description copied from interface: JDBCFilterListener

Append the SQL for this expression or value.

Specified by:

where in interface JDBCFilterListener

Parameters:

buf - the SQL buffer to append to

target - the target to act on; this will usually be a SQLPath, but depending on usage could also be other values; it will be null if the listener doesn't expect a target

arg - the value of the argument given in the filter; this will usually be a Constant, but will be null if this listener doesn't expect an argument

type - the class mapping for the query's candidate class

pm - the persistence manager that owns the query
