Interface SelectFromStep<R extends Record>

All Superinterfaces:

Attachable, java.lang.AutoCloseable, FieldLike, java.lang.Iterable<R>, Query, QueryPart, ResultQuery<R>, Select<R>, SelectConnectByStep<R>, SelectFinalStep<R>, SelectForUpdateStep<R>, SelectGroupByStep<R>, SelectHavingStep<R>, SelectLimitStep<R>, SelectOptionStep<R>, SelectOrderByStep<R>, SelectUnionStep<R>, SelectWhereStep<R>, SelectWindowStep<R>, java.io.Serializable, TableLike<R>

All Known Subinterfaces:

SelectDistinctOnStep<R>, SelectIntoStep<R>, SelectSelectStep<R>

public interface SelectFromStep<R extends Record>
extends SelectWhereStep<R>

This type is used for the Select's DSL API when selecting generic Record types.

Example:

 -- get all authors' first and last names, and the number
 -- of books they've written in German, if they have written
 -- more than five books in German in the last three years
 -- (from 2011), and sort those authors by last names
 -- limiting results to the second and third row

   SELECT T_AUTHOR.FIRST_NAME, T_AUTHOR.LAST_NAME, COUNT(*)
     FROM T_AUTHOR
     JOIN T_BOOK ON T_AUTHOR.ID = T_BOOK.AUTHOR_ID
    WHERE T_BOOK.LANGUAGE = 'DE'
      AND T_BOOK.PUBLISHED > '2008-01-01'
 GROUP BY T_AUTHOR.FIRST_NAME, T_AUTHOR.LAST_NAME
   HAVING COUNT(*) > 5
 ORDER BY T_AUTHOR.LAST_NAME ASC NULLS FIRST
    LIMIT 2
   OFFSET 1
      FOR UPDATE
       OF FIRST_NAME, LAST_NAME
       NO WAIT
 

Its equivalent in jOOQ

 create.select(TAuthor.FIRST_NAME, TAuthor.LAST_NAME, create.count())
       .from(T_AUTHOR)
       .join(T_BOOK).on(TBook.AUTHOR_ID.equal(TAuthor.ID))
       .where(TBook.LANGUAGE.equal("DE"))
       .and(TBook.PUBLISHED.greaterThan(parseDate('2008-01-01')))
       .groupBy(TAuthor.FIRST_NAME, TAuthor.LAST_NAME)
       .having(create.count().greaterThan(5))
       .orderBy(TAuthor.LAST_NAME.asc().nullsFirst())
       .limit(2)
       .offset(1)
       .forUpdate()
       .of(TAuthor.FIRST_NAME, TAuthor.LAST_NAME)
       .noWait();

Method Detail

from

@Support
SelectJoinStep<R> from(TableLike<?> table)

Add a FROM clause to the query.

from

@Support
SelectJoinStep<R> from(TableLike<?>... tables)

Add a FROM clause to the query.

from

@Support
SelectJoinStep<R> from(java.util.Collection<? extends TableLike<?>> tables)

Add a FROM clause to the query.

from

@Support
 @PlainSQL
SelectJoinStep<R> from(SQL sql)

Add a FROM clause to the query.

NOTE: When inserting plain SQL into jOOQ objects, you must guarantee syntax integrity. You may also create the possibility of malicious SQL injection. Be sure to properly use bind variables and/or escape literals when concatenated into SQL clauses!

See Also:

DSL.table(SQL), SQL

from

@Support
 @PlainSQL
SelectJoinStep<R> from(java.lang.String sql)

Add a FROM clause to the query.

NOTE: When inserting plain SQL into jOOQ objects, you must guarantee syntax integrity. You may also create the possibility of malicious SQL injection. Be sure to properly use bind variables and/or escape literals when concatenated into SQL clauses!

from

@Support
 @PlainSQL
SelectJoinStep<R> from(java.lang.String sql,
                                             java.lang.Object... bindings)

Add a FROM clause to the query.

SelectJoinStep<R> from(java.lang.String sql,
                                             QueryPart... parts)

from

@Support
SelectJoinStep<R> from(Name name)

Add a FROM clause to the query.

See Also:

DSL.table(Name)

hint

@Support
SelectFromStep<R> hint(java.lang.String hint)

Add an Oracle-style hint to the preceding select clause.

Example:

 DSLContext create = DSL.using(configuration);

 create.select(field1, field2)
       .hint("/*+ALL_ROWS*/")
       .from(table1)
       .fetch();
 

You can also use this clause for any other database, that accepts hints or options at the same syntactic location, e.g. for MySQL's SQL_CALC_FOUND_ROWS option:

 create.select(field1, field2)
       .hint("SQL_CALC_FOUND_ROWS")
       .from(table1)
       .fetch();
 

The outcome of such a query is this:

 SELECT [hint] field1, field2 FROM table1
 

For SQL Server style table hints, see Table.with(String)
