Interface MergeMatchedWhereStep<R extends Record>

All Superinterfaces:

Attachable, AutoCloseable, Merge<R>, MergeFinalStep<R>, MergeNotMatchedStep<R>, Query, QueryPart, Serializable, Statement

All Known Subinterfaces:

MergeMatchedSetMoreStep<R>

public interface MergeMatchedWhereStep<R extends Record>
extends MergeNotMatchedStep<R>

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

Method Summary

Modifier and Type	Method and Description
MergeMatchedDeleteStep<R>	where(Boolean condition) Deprecated. - 3.8.0 - [#4763] - Use where(Condition) or where(Field) instead. Due to ambiguity between calling this method using Field.equals(Object) argument, vs. calling the other method via a Field.equal(Object) argument, this method will be removed in the future.
MergeMatchedDeleteStep<R>	where(Condition condition) Add an additional WHERE clause to the preceding WHEN MATCHED THEN UPDATE clause.
MergeMatchedDeleteStep<R>	where(Field<Boolean> condition) Add an additional WHERE clause to the preceding WHEN MATCHED THEN UPDATE clause.

Method Detail

where

@Support(value={CUBRID,ORACLE,SQLSERVER})
MergeMatchedDeleteStep<R> where(Condition condition)

Add an additional WHERE clause to the preceding WHEN MATCHED THEN UPDATE clause.

In Oracle, this will produce:

 WHEN MATCHED THEN UPDATE SET .. WHERE [ condition ]
 

In SQL Server, this will produce:

 WHEN MATCHED AND [ condition ] THEN UPDATE SET ..
 

where

@Support(value={CUBRID,ORACLE,SQLSERVER})
MergeMatchedDeleteStep<R> where(Field<Boolean> condition)

Add an additional WHERE clause to the preceding WHEN MATCHED THEN UPDATE clause.

In Oracle, this will produce:

 WHEN MATCHED THEN UPDATE SET .. WHERE [ condition ]
 

In SQL Server, this will produce:

 WHEN MATCHED AND [ condition ] THEN UPDATE SET ..
 

where

@Deprecated
 @Support(value={CUBRID,ORACLE,SQLSERVER})
MergeMatchedDeleteStep<R> where(Boolean condition)

Deprecated. - 3.8.0 - [#4763] - Use where(Condition) or where(Field) instead. Due to ambiguity between calling this method using Field.equals(Object) argument, vs. calling the other method via a Field.equal(Object) argument, this method will be removed in the future.

Add an additional WHERE clause to the preceding WHEN MATCHED THEN UPDATE clause.

In Oracle, this will produce:

 WHEN MATCHED THEN UPDATE SET .. WHERE [ condition ]
 

In SQL Server, this will produce:
