Guillaume Massé updated CALCITE-5776:
-------------------------------------
Description:
{code:java}
spark.sql("select (CURRENT_DATE - INTERVAL '7 DAYS') ").show
+-----------------------------------------------------------------------+
|date_add(current_date(), (- extractansiintervaldays(INTERVAL '7' DAY)))|
+-----------------------------------------------------------------------+
| 2023-06-06|
+-----------------------------------------------------------------------+ {code}
currently the parser does not allows:
{code:java}
INTERVAL '7 DAYS' {code}
it only accepts:
{code:java}
INTERVAL '7' DAYS {code}
was:
{code:java}
spark.sql("select (CURRENT_DATE - INTERVAL '7 DAYS') ").show
+-----------------------------------------------------------------------+
|date_add(current_date(), (- extractansiintervaldays(INTERVAL '7' DAY)))|
+-----------------------------------------------------------------------+
| 2023-06-06|
+-----------------------------------------------------------------------+ {code}
currently the parser does not allows:
`- INTERVAL '7 DAYS'`
