Danny Chan <yuzhao....@gmail.com> 于2019年12月2日周一 上午9:06写道： > Dear Erin ~ > > You are right, Calcite now always hard code the parser config for JDBC > query[1], that means, Lex config for view expanding is not supported yet, > can you log a issue and probably fire a patch to support that? > > [1] > https://github.com/apache/calcite/blob/ab136b5f76a4cb951e847fcba6b414c5e80dbbe6/core/src/main/java/org/apache/calcite/prepare/CalcitePrepareImpl.java#L385 > > Best, > Danny Chan > 在 2019年12月2日 +0800 AM4:19，Erin Drummond <erin....@gmail.com>，写道： > > Hello, > > > > I am currently attempting to test out the views feature of Calcite. > > > > I am using a connection string like so: > > jdbc:calcite:lex=JAVA;model=inline:<json model> > > > > I have created a JdbcSchema that is attached to an actual database - lets > > call it "t1". I can successfully run the query "select * from t1.table > > limit 10" > > > > I then created another schema, defined like so: > > { > > "name": "viewtest", > > "tables": [ > > { "name": "test_view", "type": "view", "sql": "select * from > > t1.table limit 10" } > > ] > > } > > > > The idea is to set up connections to a bunch of physical data sources and > > then have a "views" schema that just contains views over them. > > > > However, when attempting to run the query "select * from > > viewtest.test_view", I get the following exception: > > > > StatementCallback; uncategorized SQLException for SQL [select * from > > viewtest.test_view]; SQL state [null]; error code [0]; > > Error while executing SQL \"select * from viewtest.test_view\": From line > > 1, column 15 to line 1, column 32: Object 'T1' not found; did you mean > 't1'? > > > > I can clearly see that lex=JAVA is not being used for the view and the > > default lex=ORACLE is being used. If I change the view SQL to 'select * > > from "t1".table limit 10' it works - but I don't want to have to quote > the > > identifiers oracle style, I would like the lex=JAVA that I specified on > the > > connection string to flow down to views as well. > > > > What am I missing here? > > > > Cheers, > > Erin >
