SELECT_STAR

public static final SqlSelectListType SELECT_STAR

The user requests all available columns, i.e. SELECT * FROM ...

ANY_VALUE

public static final SqlSelectListType ANY_VALUE

We just need one arbitrary value for each row. Example: If user runs COUNT (*) and COUNT cannot be pushed down, we need to return any value for each row (e.g. constant TRUE) and then EXASOL can do the COUNT.

REGULAR

public static final SqlSelectListType REGULAR

The user has to specify the desired elements.
