Interface DerivedColumnList4

All Superinterfaces:
QueryPart, Serializable
public interface DerivedColumnList4 extends QueryPart
A derived column list.

Thist type models a table name and an optional "derived column list", which can be used to name both tables and columns in one go, e.g. when aliasing a derived table or a CommonTableExpression.

Example: 


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

 Table<?> t = name("t").fields("v").as(select(one()));
 //           ^^^^^^^^^^^^^^^^^^^^^ -- DerivedColumnList

 using(configuration)
    .select()
    .from(t)
    .fetch();

Instances can be created using Name.fields(String...) and overloads.

  • Method Details

    • as

      @NotNull @Support <R extends Record4<?, ?, ?, ?>> @NotNull CommonTableExpression<R> as(ResultQuery<R> query)
      Specify a subselect to refer to by the DerivedColumnList to form a common table expression.

    • asMaterialized

      @NotNull @Support <R extends Record4<?, ?, ?, ?>> @NotNull CommonTableExpression<R> asMaterialized(ResultQuery<R> query)
      Specify a materialized subselect to refer to by the DerivedColumnList to form a common table expression.

      This adds the PostgreSQL 12 MATERIALIZED hint to the common table expression definition, or silently ignores it, if the hint is not supported.

    • asNotMaterialized

      @NotNull @Support <R extends Record4<?, ?, ?, ?>> @NotNull CommonTableExpression<R> asNotMaterialized(ResultQuery<R> query)
      Specify a non-materialized subselect to refer to by the DerivedColumnList to form a common table expression.

      This adds the PostgreSQL 12 NOT MATERIALIZED hint to the common table expression definition, or silently ignores it, if the hint is not supported.
