package org.jooq;
import org.jetbrains.annotations.NotNull;
A qualified 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(ACTOR.asterisk())
.from(ACTOR)
.fetch();
Instances can be created using Table.asterisk()
.

This expression is a convenient way to select "all but some fields". Some dialects (e.g. SQLDialect.H2
