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
