Interface SQLSubSelect
public interface SQLSubSelect
A complete SELECT definition usable in scalar, EXISTS, or IN contexts. Scalar and IN subqueries
must project exactly one column; EXISTS and NOT EXISTS accept any projection width. The compiler
validates projection width during compilation. For a scalar subquery, the database remains
responsible for runtime row-count semantics.
