Interface DerivedColumnList20

All Superinterfaces:

QueryPart, Serializable

public interface DerivedColumnList20
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.

@NotNull CommonTableExpression<R> as(ResultQuery<R> query)

Specify a subselect to refer to by the DerivedColumnList to form a common table expression.

A common table expression renders itself differently, depending on Context.declareCTE(). There are two rendering modes:

• Declaration: The common table expression renders its CTE name (this) along with the AS (query) clause. This typically happens in WITH clauses.
• Reference: The common table expression renders its alias identifier. This happens everywhere else.

@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.
