Jordan Hannel updated CALCITE-6023:
-----------------------------------
Description:
Hello all, I believe I have found a bug in SqlToRelConverter. The symptom and
repro are outlined below, and the full stacktrace is attached. This is on
calcite version 1.35.0. Any insight would be much appreciated, thanks!
When I parse the below SQL string to get a SqlNode, and call
SqlToRelConverter.convertQuery on this SqlNode, I get error:
{quote}UnsupportedOperationException: class
org.apache.calcite.sql.SqlBasicCall: LEAD(COUNT( * )) OVER (ORDER BY `dim4`)
{quote}
SQL:
{{SELECT "dim4" AS "dim7", LEAD(COUNT( * ), -1) OVER (ORDER BY "dim4") AS
"measure10"}}
{{FROM (}}
{{ SELECT "timestamp" AS "dim4" FROM "Shared.factDataset") AS "t0"}}
{{GROUP BY "dim4"}}
I have confirmed that my SqlToRelConverter instance seems generally ok, because
it is able to convert many other SqlNodes to RelNodes. After some
experimentation, I noticed that just changing `ORDER BY "dim4"` to `ORDER BY
"t0"."dim4"` fixes the issue - after that, the SqlNode successfully is
translated to a RelNode.
Below is the way I am invoking convertQuery. The error comes in the last line,
on invocation of convert
{{
var config = Frameworks.newConfigBuilder()
.operatorTable(getOperatorTable())
.parserConfig(defaultParserConfig().build())
.build();
var sqlNode = Frameworks.getPlanner(config).parse(sqlString);
var typeFactory = new JavaTypeFactoryImpl();
var calciteSchema = buildCalciteSchema(typeFactory, schema);
var catalogReader = new CalciteCatalogReader(
calciteSchema,
List.of(),
typeFactory,
CalciteConnectionConfig.DEFAULT);
var validator = new SqlValidatorImpl(
getOperatorTable(),
catalogReader,
typeFactory,
SqlValidator.Config.DEFAULT.withCallRewrite(false)) {};
var vol = new VolcanoPlanner();
vol.addRelTraitDef(ConventionTraitDef.INSTANCE);
var cluster = RelOptCluster.create(vol, new RexBuilder(typeFactory));
var sqlToRel = new SqlToRelConverter(
NOOP_EXPANDER,
validator,
catalogReader,
cluster,
StandardConvertletTable.INSTANCE,
SqlToRelConverter.config());
return sqlToRel.convertQuery(sqlNode, true, true)
}}
