<!-- Bind values are cast to their respective type when needed.
Some databases are not able to delay bind value type inference until the execution of a statement.
They will either reject the value of unknown type, or assume a possibly inappropriate type. In these
cases, jOOQ will generate an explicit cast(? as datatype) expression around the bind value to help
the query parser do its job. The exact behaviour of this mode is undefined and subject to change. -->
