public interface AlterTableChangeStep<T>
The step in the Referencing 
 
ALTER TABLE DSL used to CHANGE
 columns.
 
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
