Andrey Mashenkov updated IGNITE-17563:
--------------------------------------
Description:
As of now, CREATE INDEX support only DESC_NULLS_FIRST and ASC_NULLS_LAST
ordering.
Let's support other orderings as well (see Collation and Columncollation
classes).
Some of internal structures already supports all of null orderings.
However, we still have to fix parser to support proper 'CREATE INDEX' syntax
and pass null-ordering to storage descriptor.
was:
As of now, CreateIndexCommand support only asc/desc ordering.
Let's support NULLS FIRST/LAST ordering as well.
> Sql. Add nulls ordering support to CREATE INDEX command.
