TANG Wen-hui created CALCITE-3115: ------------------------------------- Summary: Cannot add JdbcRules which have different JdbcConvention to same VolcanoPlanner's RuleSet. Key: CALCITE-3115 URL: https://issues.apache.org/jira/browse/CALCITE-3115 Project: Calcite Issue Type: Bug Components: core Affects Versions: 1.19.0 Reporter: TANG Wen-hui Assignee: TANG Wen-hui
When we use Calcite via JDBC to run a sql which involves two difference jdbc schema: {code:java} select * from (select "a",max("b") as max_b, sum("c") as sum_c from "test"."temp" where "d" > 10 or "b" <> 'hello' group by "a", "e", "f" having "a" > 100 and max("b") < 20 limit 10) t union select "a", "b","c" from "test2"."temp2" group by "a","b","c" {code} the sql get a plan like that: {code:java} EnumerableUnion(all=[false]) JdbcToEnumerableConverter JdbcProject(a=[$0], MAX_B=[$3], SUM_C=[$4]) JdbcSort(fetch=[10]) JdbcFilter(condition=[<(CAST($3):BIGINT, 20)]) JdbcAggregate(group=[{0, 4, 5}], MAX_B=[MAX($1)], SUM_C=[SUM($2)]) JdbcFilter(condition=[AND(OR(>($3, 10), <>($1, 'hello')), >($0, 100))]) JdbcTableScan(table=[[test, temp]]) EnumerableAggregate(group=[{0, 1, 2}]) JdbcToEnumerableConverter JdbcTableScan(table=[[test2, temp2]]) {code} And the EnumerableAggregate for table test2.temp2 cannot be convert to JdbcAggregate. -- This message was sent by Atlassian JIRA (v7.6.3#76005)
