Ilya Kasnacheev created IGNITE-8639:
---------------------------------------
Summary: Query with a lot of nesting causes NPE in
org.h2.util.StringUtils.indent
Key: IGNITE-8639
URL: https://issues.apache.org/jira/browse/IGNITE-8639
Project: Ignite
Issue Type: Bug
Components: sql
Affects Versions: 2.6
Reporter: Ilya Kasnacheev
Attachments: SqlNestedQuerySelfTest.java
Worked in 1.7!
But now:
{code}
sql("WITH cacheJoin (txId, stage, tStamp)" +
" AS (SELECT t.txId, o.stage, o.tStamp FROM txs t INNER JOIN ops
o ON t.txId = o.txId)" +
" SELECT ou.stage, COUNT(*) as cou, SUM(CASE WHEN ou.stage =
in.stage THEN 1 ELSE 0 END) AS ttl" +
" FROM (SELECT txId, stage FROM cacheJoin cte GROUP BY txId,
stage) ou" +
" INNER JOIN (SELECT mx.txId, mx.stage FROM (SELECT txId,
tStamp, stage FROM cacheJoin cte) mx" +
" INNER JOIN (SELECT txId, MAX(tStamp) AS maxTStamp FROM
cacheJoin cte GROUP BY txId) mix" +
" ON mx.txId = mix.txId AND mx.tStamp = mix.maxTStamp) in
ON ou.txId = in.txId" +
" GROUP BY ou.stage");
{code}
{code}
