Interface UpdateSetStep<R extends Record>

All Known Subinterfaces:

UpdateSetFirstStep<R>, UpdateSetMoreStep<R>

public interface UpdateSetStep<R extends Record>

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

Example:

 DSLContext create = DSL.using(configuration);

 create.update(table)
       .set(field1, value1)
       .set(field2, value2)
       .where(field1.greaterThan(100))
       .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> @NotNull UpdateSetMoreStep<R> set(Field<T> field,
                                                           T value)

Set a value for a field in the UPDATE statement.

                                                           Field<T> value)

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

Set a value for a field in the UPDATE statement.

setNull

@NotNull
 @Support
<T> @NotNull UpdateSetMoreStep<R> setNull(Field<T> field)

Set a null value for a field in the UPDATE statement.

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

set

@NotNull
 @Support
@NotNull UpdateSetMoreStep<R> set(Map<?,?> map)

Set a value for a field in the UPDATE statement.

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
@NotNull UpdateSetMoreStep<R> set(Record record)

Set a value for a field in the UPDATE statement.

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.
