Roman Churganov updated CALCITE-5042:
-------------------------------------
Description:
Execute query like:
{{SELECT f.id FROM sch1.foo as f}}
{{ JOIN sch1.foo br ON br.id = f.id }}
{{ JOIN sch1.baz bz ON bz.id = br.id }}
{{ WHERE f.id = '0'}}
{{Calcite prepares SQL using JDBC adapter like: }}
{{SELECT "t1"."ID" FROM ( SELECT "ID" FROM "BAZ" ) AS "t"}}
INNER JOIN (
{{ ( SELECT "ID" FROM "FOO" WHERE "ID" = '0') AS "t1"}}
{{ INNER JOIN (SELECT "ID" FROM "FOO") AS "t2" }}{{ }}
{{ ON "t1"."ID" = "t2"."ID"}}
{{) ON "t"."ID" = "t2"."ID" }}
which seem like have incorrect sub-query, though most of the databases can
execute it, but Caclite itself cannot parse and gives error like:
Caused by: org.apache.calcite.sql.parser.impl.ParseException: Encountered "AS"
at line 3, column 88.
Was expecting one of:
"EXCEPT" ...
"FETCH" ...
"INTERSECT" ...
"LIMIT" ...
"OFFSET" ...
"ORDER" ...
"MINUS" ...
"UNION" ...
")" ...
"." ...
"NOT" ...
"IN" ...
{{see example [https://www.db-fiddle.com/f/oCr3VKkT2QmKgWro54Wzfc/4] }}
was:
