I think you're looking for parser.parsePlan instead of parser.parseExpression. The second query doesn't show an error for parsePlan.

org.apache.spark.sql.catalyst.plans.logical.Project.getClass calls the getClass method of the companion object for org.apache.spark.sql.catalyst.plans.logical.Project which is a singleton instance of the class org.apache.spark.sql.catalyst.plans.logical.Project$ (in this case, looking at Spark's code shows that to be a case class with a synthetic companion object).

You can get the class object for org.apache.spark.sql.catalyst.plans.logical.Project with:

I need to convert all the table name and column name to another name in a SQL query which will be in form of string and I have to do it using the Calcite SQL parser. I only know that I have to implement the visitor interface, but I have no clue how to do it. Please help me out and give me some basic information as to how to do that.

Sorry for asking basic question like this, but I went through the documentation of Calcite sqlparser and got no idea what to do, also there are minimal tutorials on it.

I am trying to connect Gemfire 8.2 using apache calcite geode adopter. As per following logs its connectied properly but while try to execute query getting exception .

Note : http://calcite.apache.org/news/2018/03/19/release-1.16.0/

ANSWER

Answered 2018-Mar-21 at 16:51

The Geode Adapter is compiled with Geode version: 1.3 (https://github.com/apache/calcite/blob/master/pom.xml#L79) that corresponds to Gemfire 9.x.

Because the Gemfire 8.x is code incompatible with Gemfire 9.x. you would not be able to use the Geode Adapter on the Gemfire 8.x or older. Furthermore the OQL in Gemfire 8.x doesn't support GROUP BY construct either.

A comment on calcite jira for my question here answers the question with one approach-

This is because SqlStdOperatorTable.instance() did some initialization work for the registered functions. So an invoke of #register after it would not work as expected. The correct way is to use ListSqlOperatorTable and chained it with the StdSqlOperatorTable with ChainedSqlOperatorTable, the presudo code may like this:
