```
public String toString()
```
    Description copied from interface: QueryPart
    
    Render a SQL string representation of this QueryPart.
    For improved debugging, this renders a SQL string of this QueryPart with inlined bind variables. If this QueryPart is Attachable, then the attached Configuration may be used for rendering the SQL string, including SQLDialect and Settings. Do note that most QueryPart instances are not attached to a Configuration, and thus there is no guarantee that the SQL string will make sense in the context of a specific database.

```
public int hashCode()
```
    Description copied from interface: QueryPart
    
    Generate a hash code from this QueryPart.
    In general, QueryPart hash codes are the same as the hash codes generated from QueryPart.toString(). This guarantees consistent behaviour with QueryPart.equals(Object)
    Some QueryPart implementations may choose to override this behaviour for improved performance, as QueryPart.toString() is an expensive operation, if called many times.
    
    Specified by:
    
    hashCode in interface QueryPart
    
    Returns:
    
    The QueryPart hash code
  - equals
```
public boolean equals(Object obj)
```
    Description copied from interface: QueryPart
    
    Check whether this QueryPart can be considered equal to another QueryPart.
    In general, QueryPart equality is defined in terms of QueryPart.toString() equality. In other words, two query parts are considered equal if their rendered SQL (with inlined bind variables) is equal. This means that the two query parts do not necessarily have to be of the same type.
    Some QueryPart implementations may choose to override this behaviour for improved performance, as QueryPart.toString() is an expensive operation, if called many times.
    
    Specified by:
    
    equals in interface QueryPart
