---------------------------------------
Summary: Calcite engine. Lack of date formatting functions (was: Calcite
engine. Lack of date/number formatting funtions)
> Calcite engine. Lack of date formatting functions
> -------------------------------------------------
>
> Key: IGNITE-23684
> URL: https://issues.apache.org/jira/browse/IGNITE-23684
> Project: Ignite
> Issue Type: Improvement
> Reporter: Aleksey Plekhanov
> Assignee: Aleksey Plekhanov
> Priority: Major
> Labels: calcite, ise
>
> In the Calcite SQL engine we don't have any date/time/number formating
> function, and date/time/number parsing functions with custom format.
> H2 engine has TO_DATE, TO_CHAR, TO_NUMBER (Oracle compatible) and own
> FORMATDATETIME, PARSEDATETIME.
> Apache Calcite has TO_DATE and TO_CHAR functions in internal library, but not
> exposed to our SQL engine now. Also it supports CAST(... AS DATE FORMAT ...),
> but we also don't support this syntax.
> Both TO_DATE and CAST-FORMAT are not part of SQL standard, but, perhaps it's
> better to implement TO_DATE (also TO_CHAR, TO_NUMBER) for compatibility with
> H2 engine.
