Interface Asterisk

All Superinterfaces:
QueryPart, SelectFieldOrAsterisk, Serializable
public non-sealed interface Asterisk extends SelectFieldOrAsterisk
An unqualified asterisk.

Asterisks (qualified and unqualified) are expressions that can be used exclusively in SELECT clauses and a few other clauses that explicitly allow for asterisks, including RETURNING on DML statements. Asterisks are syntax sugar in SQL, which are expanded to a column list by the parser once all the columns in the FROM clause are known.

Example: 


 // Assuming import static org.jooq.impl.DSL.*;

 using(configuration)
    .select(asterisk())
    .from(ACTOR)
    .fetch();

Instances can be created using DSL.asterisk().

    • except

      @NotNull @Support @NotNull Asterisk except(String... fieldNames)
      The asterisk (* EXCEPT (fields)) expression to be used in SELECT clauses.

      This expression is a convenient way to select "all but some fields". Some dialects (e.g. SQLDialect.H2) implement this feature natively. In other dialects, jOOQ expands the asterisk if possible.

    • except

      @NotNull @Support @NotNull Asterisk except(Name... fieldNames)
      The asterisk (*) to be used in SELECT clauses.

      This expression is a convenient way to select "all but some fields". Some dialects (e.g. SQLDialect.H2) implement this feature natively. In other dialects, jOOQ expands the asterisk if possible.

    • except

      @NotNull @Support @NotNull Asterisk except(Field<?>... fields)
      The asterisk (*) to be used in SELECT clauses.

      This expression is a convenient way to select "all but some fields". Some dialects (e.g. SQLDialect.H2) implement this feature natively. In other dialects, jOOQ expands the asterisk if possible.

    • $except

      @Experimental @NotNull @NotNull QOM.UnmodifiableList<? extends Field<?>> $except()
      Experimental query object model accessor method, see also QOM. Subject to change in future jOOQ versions, use at your own risk.
