Iurii Gerzhedovich updated IGNITE-22866:
----------------------------------------
Description:
*Description:*
Need to support recursive queries.
The query
{code:java}
WITH RECURSIVE t(n) AS (SELECT 1 UNION ALL SELECT n + 1 FROM t WHERE n < 100)
SELECT sum(n) FROM t; {code}
should return
{code:java}
5050 {code}
currently returns error
{noformat}
org.apache.ignite.sql.SqlException: IGN-CMN-65535
TraceId:c2961dbf-64fd-4806-a2d9-20368f8454e5 There are not enough rules to
produce a node with desired properties: convention=IGNITE, distr=single,
sort=[].
Missing conversions are LogicalRepeatUnion[convention: NONE -> IGNITE, distr:
any -> single], LogicalRepeatUnion[convention: NONE -> IGNITE, distr: any ->
random]
There are 2 empty subsets:
Empty subset 0: rel#92:RelSubset#6.IGNITE.single.[], the relevant part of the
original plan is as follows
87:LogicalRepeatUnion(all=[true])
78:LogicalTableSpool(subset=[rel#79:RelSubset#1.NONE.any.[0]],
readType=[LAZY], writeType=[LAZY], table=[[T]])
1:LogicalValues(subset=[rel#77:RelSubset#0.NONE.any.[0]], tuples=[[{ 1 }]])
85:LogicalTableSpool(subset=[rel#86:RelSubset#5.NONE.any.[]],
readType=[LAZY], writeType=[LAZY], table=[[T]])
83:LogicalProject(subset=[rel#84:RelSubset#4.NONE.any.[]], EXPR$0=[+($0,
1)])
81:LogicalFilter(subset=[rel#82:RelSubset#3.NONE.any.[]],
condition=[<($0, 100)])
2:LogicalTableScan(subset=[rel#80:RelSubset#2.NONE.any.[]], table=[[T]])
...
(part of the debug error output was cut off)
{noformat}
Let's consider the ticket to make PoC to support RECURSIVE CTE queries.
