Summary: SqlNode#unparse hides an alias table when using CTE
Key: CALCITE-5119
URL: https://issues.apache.org/jira/browse/CALCITE-5119
Project: Calcite
Issue Type: Bug
Components: core
Affects Versions: 1.30.0
Reporter: Mitsunori Komatsu
Hi team,
I found SqlNode#unparse hides an alias table when using CTE.
{code:java}
val planner = Frameworks.getPlanner(config)
val sql = """
WITH cte AS (
select 42 as i
)
SELECT i FROM (
SELECT [i] from cte
) AS [alias]
ORDER BY [alias].[i]
""".trimIndent()
val node = planner.parse(sql)
println(node.toSqlString { c ->
c.withDialect(PrestoSqlDialect.DEFAULT)
.withAlwaysUseParentheses(false)
.withSubQueryStyle(SqlWriter.SubQueryStyle.HYDE)
.withClauseStartsLine(false)
.withClauseEndsLine(false)
}) {code}
This code shows the following
{code:java}
WITH "cte" AS (SELECT 42 AS "i")
(SELECT "i" FROM (SELECT "i" FROM "cte") AS "alias")
ORDER BY "alias"."i"{code}
The `AS "alias"` is inside a block and the last `ORDER BY` can't find `alias`
and this query fails with Presto. I think the output should be as follows
{code:java}
WITH "cte" AS (SELECT 42 AS "i")
SELECT "i" FROM (SELECT "i" FROM "cte") AS "alias"
ORDER BY "alias"."i"{code}

[jira] [Created] (CALCITE-5135) Planner#parse can't parse DAY() function

Hi team,
I might be missing something, but `Planner#parse` can't parse `DAY()` function
while it can parse other YEAR(), MONTH(), HOUR() and so on.
{code:java}
import org.apache.calcite.sql.parser.SqlParseException;
import org.apache.calcite.sql.validate.SqlValidator;
import org.apache.calcite.tools.FrameworkConfig;
import org.apache.calcite.tools.Frameworks;
import org.apache.calcite.tools.Planner;
public class Main {
public static void main(String[] args) throws SqlParseException {
FrameworkConfig config = Frameworks.newConfigBuilder().build();
{
Planner planner = Frameworks.getPlanner(config);
System.out.println(planner.parse("select months(t) from tbl"));
}
{
Planner planner = Frameworks.getPlanner(config);
System.out.println(planner.parse("select month(t) from tbl"));
}
{
Planner planner = Frameworks.getPlanner(config);
System.out.println(planner.parse("select hours(t) from tbl"));
}
{
Planner planner = Frameworks.getPlanner(config);
System.out.println(planner.parse("select hour(t) from tbl"));
}
{
Planner planner = Frameworks.getPlanner(config);
System.out.println(planner.parse("select days(t) from tbl"));
}
{
Planner planner = Frameworks.getPlanner(config);
// This throws `org.apache.calcite.sql.parser.SqlParseException:
Encountered "day" ...`
System.out.println(planner.parse("select day(t) from tbl"));
}
}
}
{code}
Is this a bug? Is there any way to parse DAY() function? Thanks.

[jira] [Created] (CALCITE-5143) Planner#parse fails to parse a function when HOUR is passed as an argument

Summary: Planner#parse fails to parse a function when HOUR is
passed as an argument
Key: CALCITE-5143

I'm trying to parse and rewrite some SQL dialects including SQL Server which
supports some functions that receive HOUR as an argument using. But Calcite's
Planner#parse can't handle this kind of SQL.
{code:java}
FrameworkConfig config = Frameworks.newConfigBuilder().build();
Planner planner = Frameworks.getPlanner(config);
System.out.println(planner.parse("SELECT DATEDIFF(HOUR, NOW(), NOW())")); {code}
{code:java}
Exception in thread "main" org.apache.calcite.sql.parser.SqlParseException:
Incorrect syntax near the keyword 'HOUR' at line 2, column 21.
Was expecting one of:
"ALL" ...
"ARRAY" ...
"CASE" ...
:
"GROUPING" ...
"HOUR" ...
"HOUR" "(" ...
"*" ...
")" ...

at org.apache.calcite.tools.Planner.parse(Planner.java:50) {code}
This issue happens with other date/time keyword-ish ones like YEAR.
I guess it happens because HOUR and YEAR are reserved keywords.
Is this an expected behavior? If so, is there any workaround?
