* System property that instructs Spring to ignore {@link java.sql.ParameterMetaData#getParameterType}
* completely, i.e. to never even attempt to retrieve {@link PreparedStatement#getParameterMetaData()}.
* <p>The default is "false", trying {@code getParameterType} calls first and falling back to
* {@link PreparedStatement#setNull} / {@link PreparedStatement#setObject} calls based on well-known
* behavior of common databases. Spring records JDBC drivers with non-working {@code getParameterType}
* implementations and won't attempt to call that method for that driver again, always falling back.
* <p>Consider switching this flag to "true" if you experience misbehavior at runtime, e.g. with
* a connection pool setting back the {@link PreparedStatement} instance in case of an exception
* thrown from {@code getParameterType} (e.g. on JBoss AS 7).
