[jira] [Updated] (CALCITE-4091) Temporal Intervals improvements
[ https://issues.apache.org/jira/browse/CALCITE-4091?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Dan Cojocaru updated CALCITE-4091:
----------------------------------
Description:
Using this parser configuration:
{code:java}
final FrameworkConfig config = Frameworks.newConfigBuilder() .parserConfig(SqlParser.configBuilder()
.setConformance(MYSQL_5).setLex(MYSQL).build())
.programs(Programs.ofRules(RULE_SET))
.build();
{code}
*Case 1.* When parsing :
{code:java}
SELECT DATE_ADD('2008-01-02', INTERVAL '31' WEEK)
{code}
fails with :
{code:java}
Encountered "WEEK" at line 1, column 45.
{code}
*Case 2.* When parsing:
{code:java}
SELECT DATE_ADD('2008-01-02', INTERVAL 31 DAY)
{code}
fails with
{code:java}
Encountered "INTERVAL 31" at line 1, column 31.
{code}
*Case 3*. When parsing
{code:java}
SELECT DATE_ADD('1970-01-01 12:00:00', INTERVAL CAST(6/4 AS DECIMAL(3,1)) HOUR_MINUTE)
{code}
or
{code:java}
SELECT DATE_ADD('2008-01-02', INTERVAL ((select 1 from dual) - '31') DAY);
{code}
fails with:
{code:java}
Encountered "INTERVAL CAST".
{code}
{code:java}
Encountered "INTERVAL (
{code}
Conclusion: INTERVAL is not fully supported:
Case 1 : WEEK time unit argument is not allowed, for other seems to work fine
Case 2: expressions(expr) that are nonStrings are not allowed
Case 3: expressions(expr) are not allowed at all, only string values are allowed
According to MySql documentation [https://dev.mysql.com/doc/refman/8.0/en/expressions.html#temporal-intervals]
all the above cases should be parsed with success.
