Calcite Team,
Are there any plans to support JDBC 4.2 or 4.3 on the roadmap?
Also we have code that adds a JdbcSchema to the rootSchema via:
rootSchema.add(DB_SCHEMA, JdbcSchema.create(rootSchema, DB_SCHEMA, dataSource,
null, DB_SCHEMA));
When querying via JPA against an H2 DB that has a table containing a “Binary
Large Object” (a Blob) CalciteJdbc41Connection creates a
CalciteJdbc41PreparedStatement which creates a CalciteResultSet (a subclass of
AvaticaResultSet) which then creates an ArrayIteratorCursor (a subclass of
AbstractCursor) which has this implementation:
public Blob getBlob() throws SQLException {
throw cannotConvert(“Blob”)
}
Is there anything I can do to support Blobs/Clobs/Arrays/Refs/etc? Maybe I’m
doing something incorrectly in my Connection initialization. I am NOT
initializing anything with the RelOptPlanner like Rules. It didn’t appear that
I needed to.
Thanks in advance.
Tony
