Detailed Description
Abstract base class used for implementing table field-related actions.

, used for constructing null action

Member Function Documentation
◆ fieldName()
|
inline |
- Returns
- field name for this action
Definition at line 255 of file KDbAlter.h.
◆ setFieldName()
|
inline |
Sets field name for this action.
Definition at line 273 of file KDbAlter.h.
◆ uid()
|
inline |
- Returns
- field's unique identifier This id is needed because in the meantime there can be more than one field sharing the same name, so we need to identify them unambiguously. After the (valid) altering is completed all the names will be unique.
Example scenario when user exchanged the field names:
- At the beginning: [field A], [field B]
- Rename the 1st field to B: [field B], [field B]
- Rename the 2nd field to A: [field B], [field A]
