Julian Hyde created CALCITE-4266: ------------------------------------ Summary: JDBC adapter throws UnsupportedOperationException if query contains range predicate on columns from sub-query Key: CALCITE-4266 URL: https://issues.apache.org/jira/browse/CALCITE-4266 Project: Calcite Issue Type: Bug Reporter: Julian Hyde
JDBC adapter throws {{UnsupportedOperationException}} if query contains range predicate on columns from sub-query. The query {code} SELECT CASE WHEN v.g IN (0, 1) THEN 0 ELSE 1 END FROM (SELECT * FROM "foodmart"."customer") AS c, (SELECT 0 AS g) AS v GROUP BY v.g {code} contains a range (by virtue of the {{IN (0, 1)}}) and throws {noformat} java.lang.UnsupportedOperationException at org.apache.calcite.rel.rel2sql.SqlImplementor$Result$1.implementor(SqlImplementor.java:1597) at org.apache.calcite.rel.rel2sql.SqlImplementor$Context.lambda$toSql$0(SqlImplementor.java:862) at java.base/java.util.stream.ReferencePipeline$3$1.accept(ReferencePipeline.java:195) {noformat} The problem is that, in order to simplify a Sarg (see CALCITE-4173), the {{implementor()}} is being called in a context where it was not called before. The solution is to implement the {{SqlImplementor.Context.implementor()}} method in more sub-classes. -- This message was sent by Atlassian Jira (v8.3.4#803005)
