Viktor Batytskyi updated CALCITE-1388:
--------------------------------------
Description:
The following query contains ROLLUP operator in GROUP BY clause.
{code:sql}
SELECT player_id, video_id, SUM(clicks)
FROM Table
GROUP BY ROLLUP((player_id, video_id))
{code}
After the sql string is parsed and validated by executing:
{code}
val planner = Frameworks.getPlanner(config)
val sqlNode = planner.parse(mockedSql)
val validatedSql = planner.validate(sqlNode)
val relExpression = planner.rel(validatedSql).project()
{code}
The resulting relExpression can't be transformed back to a query:
{code}
private val VERTICA = SqlDialect.DatabaseProduct.VERTICA.getDialect
.....................
val sql = new RelToSqlConverter(VERTICA).visitChild(0,
relExpression).asQuery.toSqlString(VERTICA).getSql
{code}
The exception is thrown:
