> In the MetaStoreDirectSql class when IN clause is used, the query statement
> is created via string concatenation.
> Since JDBC API allows only one literal for one “?” parameter,
> PreparedStatement doesn’t work for IN clause queries. To create the
> PreparedStatement query dynamically based on the size of the elements in IN
> clause, the makeParams() should be used instead of concatenation.
