		int	uid )

FieldActionBase() [2/2]

Member Function Documentation

fieldName()

QString KDbAlterTableHandler::FieldActionBase::fieldName ( ) const

inline

Returns

field name for this action

Definition at line 255 of file KDbAlter.h.

setFieldName()

void KDbAlterTableHandler::FieldActionBase::setFieldName ( const QString & fieldName )

inline

Sets field name for this action.

Definition at line 273 of file KDbAlter.h.

uid()

int KDbAlterTableHandler::FieldActionBase::uid ( ) const

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:

1. At the beginning: [field A], [field B]
2. Rename the 1st field to B: [field B], [field B]
3. Rename the 2nd field to A: [field B], [field A]

Definition at line 268 of file KDbAlter.h.
