Interface InsertOnDuplicateStep<R extends Record>

All Superinterfaces:

Adapter, Attachable, Insert<R>, InsertFinalStep<R>, InsertReturningStep<R>, Query, QueryPart, Serializable

All Known Subinterfaces:

InsertSetMoreStep<R>, InsertValuesStep<R>

public interface InsertOnDuplicateStep<R extends Record>
extends InsertFinalStep<R>, InsertReturningStep<R>

This type is used for the Insert's DSL API.

Example:

 Factory create = new Factory();

 create.insertInto(table, field1, field2)
       .values(value1, value2)
       .values(value3, value4)
       .onDuplicateKeyUpdate()
       .set(field1, value1)
       .set(field2, value2)
       .execute();

Method Detail

onDuplicateKeyUpdate

InsertOnDuplicateSetStep<R> onDuplicateKeyUpdate()

Add an ON DUPLICATE KEY UPDATE clause to this insert query.

This will try to INSERT a record. If there is a primary key or unique key in this INSERT statement's affected table that matches the value being inserted, then the UPDATE clause is executed instead.

MySQL and CUBRID natively implements this type of clause. jOOQ can simulate this clause using a MERGE statement on some other databases. The conditions for a RDBMS to simulate this clause are:

• The INSERT statement's table is an UpdatableTable
• The RDBMS supports the MERGE clause (see Factory.mergeInto(Table)).

These are the dialects that fulfill the above requirements:

onDuplicateKeyIgnore

InsertFinalStep<R> onDuplicateKeyIgnore()

Add an ON DUPLICATE KEY IGNORE clause to this insert query.

This will try to INSERT a record. If there is a primary key or unique key in this INSERT statement's affected table that matches the value being inserted, then the INSERT statement is ignored.

This clause is not actually supported in this form by any database, but can be simulated as such:

Dialect	Simulation
SQLDialect.MYSQL	INSERT IGNORE INTO ..
SQLDialect.CUBRID	INSERT INTO .. ON DUPLICATE KEY UPDATE [any-field] = [any-field]
SQLDialect.DB2 SQLDialect.HSQLDB SQLDialect.ORACLE SQLDialect.SQLSERVER SQLDialect.SYBASE	MERGE INTO [dst] USING ([values]) src ON [dst.key] = [src.key] WHEN NOT MATCHED THEN INSERT ..
