Changes to JoinUtils.java: 1. Enhanced isScalarSubquery() method to detect scalar subqueries represented as Values nodes: - Added support for org.apache.calcite.rel.logical.LogicalValues - Added support for org.apache.drill.exec.planner.common.DrillValuesRelBase - Both check if tuples.size() <= 1 to identify scalar subqueries 2. Modified checkCartesianJoin() method to allow cartesian joins with scalar subqueries: - Added hasScalarSubqueryInput() checks for both INNER and non-INNER joins - Returns false (not a problematic cartesian join) when a scalar subquery is detected - Allows nested loop joins for scalar subqueries instead of throwing errors Reverted problematic changes: - DrillRexBuilder.java: Removed ensureType() override that added casts for nullability - DrillRelFactories.java: Removed nullability normalization in FilterFactory - DefaultSqlHandler.java: Removed extra logging Test results: - TestSetOp tests (testIntersectCancellation, testUnionFilterPushDownOverOr): PASSING - TestJoinNullable tests: PASSING - No regression in other tests --- .../exec/physical/impl/join/JoinUtils.java | 77 ++++++++++++++++++- 1 file changed, 76 insertions(+), 1 deletion(-) diff --git a/exec/java-exec/src/main/java/org/apache/drill/exec/physical/impl/join/JoinUtils.java b/exec/java-exec/src/main/java/org/apache/drill/exec/physical/impl/join/JoinUtils.java index d6b7fffa760..da8eb0856eb 100644 --- a/exec/java-exec/src/main/java/org/apache/drill/exec/physical/impl/join/JoinUtils.java +++ b/exec/java-exec/src/main/java/org/apache/drill/exec/physical/impl/join/JoinUtils.java @@ -121,10 +121,20 @@ public static boolean checkCartesianJoin(RelNode relNode, List leftKeys RexNode remaining = RelOptUtil.splitJoinCondition(left, right, joinRel.getCondition(), leftKeys, rightKeys, filterNulls);

There are several methods for creating literals in {@link RexBuilder}: + * {@link RexBuilder#makeLiteral(boolean)} and so forth. + * + *

How is the value stored? In that respect, the class is somewhat of a black + * box. There is a {@link #getValue} method which returns the value as an + * object, but the type of that value is implementation detail, and it is best + * that your code does not depend upon that knowledge. It is better to use + * task-oriented methods such as {@link #getValue2} and + * {@link #toJavaString}. + * + *

Allowable types for RexLiteral instances
TypeNameMeaningValue type
{@link SqlTypeName#NULL}The null value. It has its own special type.null
{@link SqlTypeName#BOOLEAN}Boolean, namely TRUE, FALSE or + * UNKNOWN.{@link Boolean}, or null represents the UNKNOWN value

{@link SqlTypeName#DOUBLE}, + * {@link SqlTypeName#REAL}, + * {@link SqlTypeName#FLOAT}Approximate number, for example 6.023E-23.{@link Double}.
{@link SqlTypeName#DATE}Date, for example DATE '1969-04'29'{@link Calendar}; + * also {@link Calendar} (UTC time zone) + * and {@link Integer} (days since POSIX epoch)
{@link SqlTypeName#TIME}Time, for example TIME '18:37:42.567'{@link Calendar}; + * also {@link Calendar} (UTC time zone) + * and {@link Integer} (milliseconds since midnight)
{@link SqlTypeName#TIMESTAMP}Timestamp, for example TIMESTAMP '1969-04-29 + * 18:37:42.567'{@link TimestampString}; + * also {@link Calendar} (UTC time zone) + * and {@link Long} (milliseconds since POSIX epoch)

{@link SqlTypeName#BINARY}Binary constant, for example X'7F34'. (The number of hexits + * must be even; see above.) These constants are always BINARY, never + * VARBINARY.{@link ByteBuffer}; + * also {@code byte[]}
{@link SqlTypeName#SYMBOL}A symbol is a special type used to make parsing easier; it is not part of + * the SQL standard, and is not exposed to end-users.
