Yingyu Wang created CALCITE-5252:
------------------------------------
Summary: Unparsing "WITH ... AS (SELECT ... UNION select ...)"
missing parentheses
Key: CALCITE-5252
URL: https://issues.apache.org/jira/browse/CALCITE-5252
Project: Calcite
Issue Type: Bug
Reporter: Yingyu Wang
{code:java}
//testkit/src/main/java/org/apache/calcite/sql/parser/SqlParserTest.java
@Test void testWithUnion1() {
finalStringsql="with emp2 as (select * from emp union select * from emp)\n"
+"select * from emp2\n";
finalStringexpected="WITH `EMP2` AS (SELECT *\n"
+"FROM `EMP`\n"
+"UNION\n"
+"SELECT *\n"
+"FROM `EMP`) (SELECT *\n"
+"FROM `EMP2`)";
sql(sql).ok(expected);
}{code}
This test fails with SqlUnParserTest (
core/src/test/java/org/apache/calcite/sql/parser/SqlUnParserTest.java) because
the parentheses after AS are missing.
