Interface SelectWindowStep<R extends Record>

All Superinterfaces:

Attachable, AutoCloseable, FieldLike, Iterable<R>, Query, QueryPart, ResultQuery<R>, Select<R>, SelectFinalStep<R>, SelectForUpdateStep<R>, SelectLimitStep<R>, SelectOptionStep<R>, SelectOrderByStep<R>, SelectUnionStep<R>, Serializable, Statement, TableLike<R>

All Known Subinterfaces:

SelectConditionStep<R>, SelectConnectByAfterStartWithConditionStep<R>, SelectConnectByConditionStep<R>, SelectConnectByStep<R>, SelectDistinctOnStep<R>, SelectFromStep<R>, SelectGroupByStep<R>, SelectHavingConditionStep<R>, SelectHavingStep<R>, SelectIntoStep<R>, SelectJoinStep<R>, SelectOnConditionStep<R>, SelectOptionalOnStep<R>, SelectSelectStep<R>, SelectStartWithStep<R>, SelectWhereStep<R>

public interface SelectWindowStep<R extends Record>
extends SelectOrderByStep<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();

Referencing XYZ*Step types directly from client code

It is usually not recommended to reference any XYZ*Step types directly from client code, or assign them to local variables. When writing dynamic SQL, creating a statement's components dynamically, and passing them to the DSL API statically is usually a better choice. See the manual's section about dynamic SQL for details: https://www.jooq.org/doc/latest/manual/sql-building/dynamic-sql.

Drawbacks of referencing the XYZ*Step types directly:

• They're operating on mutable implementations (as of jOOQ 3.x)
• They're less composable and not easy to get right when dynamic SQL gets complex
• They're less readable
• They might have binary incompatible changes between minor releases

Method Detail

window

@Support(value={AURORA_POSTGRES,CUBRID,DB2,FIREBIRD_3_0,HANA,INFORMIX,MARIADB,MYSQL_8_0,ORACLE,POSTGRES,SQLDATAWAREHOUSE,SQLSERVER,SYBASE,TERADATA,VERTICA})
SelectOrderByStep<R> window(WindowDefinition... definitions)

Add a WINDOW clause to the statement.

Use the WINDOW clause to specify window definitions for reuse among several window functions.

The WINDOW clause is only natively supported by

• SQLDialect.AURORA_POSTGRES
• SQLDialect.H2
• SQLDialect.MYSQL
• SQLDialect.POSTGRES
• SQLDialect.SQLITE
• SQLDialect.SYBASE

If you are using any other dialect, you can still use this clause. jOOQ will inline window definitions where they are referenced.
