Field Detail

IMPLICIT_ALIASback to summary
public static final String IMPLICIT_ALIAS

This is a special alias that we use for implicit joins within the FROM clause. Passing this alias will cause that we don't generate a unique alias for a path, but instead use a null alias. The effect of this is, that we use the same table group for a query like `... exists ( from alias.intermediate.attribute where alias.intermediate.otherAttribute is not null )` for the path in the FROM clause and the one in the WHERE clause.
