Interface MergeMatchedSetStep<R extends Record>

All Known Subinterfaces:

MergeMatchedSetMoreStep<R>

public interface MergeMatchedSetStep<R extends Record>

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

Example:

 DSLContext create = DSL.using(configuration);

 create.mergeInto(table)
       .using(select)
       .on(condition)
       .whenMatchedThenUpdate()
       .set(field1, value1)
       .set(field2, value2)
       .whenNotMatchedThenInsert(field1, field2)
       .values(value1, value2)
       .execute();
 

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

                                            T value)

Set values for UPDATE in the MERGE statement's WHEN MATCHED clause.

                                            Field<T> value)

Set values for UPDATE in the MERGE statement's WHEN MATCHED clause.

<T> @NotNull MergeMatchedSetMoreStep<R> set(Field<T> field,
                                            Select<? extends Record1<T>> value)

Set values for UPDATE in the MERGE statement's WHEN MATCHED clause.

setNull

@NotNull
@Support({CUBRID,DB2,DERBY,FIREBIRD_3_0,H2,HANA,HSQLDB,ORACLE,SQLSERVER,SYBASE,TERADATA,VERTICA})
<T> @NotNull MergeMatchedSetMoreStep<R> setNull(Field<T> field)

Set a null value for UPDATE in the MERGE statement's WHEN MATCHED clause.

This method is convenience for calling set(Field, Object), without the necessity of casting the Java null literal to (T).

set

@NotNull
@Support({CUBRID,DB2,DERBY,FIREBIRD_3_0,H2,HANA,HSQLDB,ORACLE,SQLSERVER,SYBASE,TERADATA,VERTICA})
@NotNull MergeMatchedSetMoreStep<R> set(Map<?,?> map)

Set multiple values for UPDATE in the MERGE statement's WHEN MATCHED clause.

Keys can either be of type String, Name, or Field.

Values can either be of type <T> or Field<T>. jOOQ will attempt to convert values to their corresponding field's type.

set

@NotNull
@Support({CUBRID,DB2,DERBY,FIREBIRD_3_0,H2,HANA,HSQLDB,ORACLE,SQLSERVER,SYBASE,TERADATA,VERTICA})
@NotNull MergeMatchedSetMoreStep<R> set(Record record)

Set multiple values for UPDATE in the MERGE statement's WHEN MATCHED clause.

This is the same as calling set(Map) with the argument record treated as a Map<Field<?>, Object>, except that the Record.changed() flags are taken into consideration in order to update only changed values.
