Delegate UpdateField
This delegate is used by the Data layer if it has updated - manipulated - the data in a query, and the client might wish to know.
Namespace: SuperOffice.Data.SQL
Assembly: SoDataBase.dll
Syntax
public delegate void UpdateField(FieldInfo whichField, Parameter newValue)Parameters
| Type | Name | Description |
|---|---|---|
| FieldInfo | whichField | FieldInfo taken from the same TableInfo as the query's table(s) |
| Parameter | newValue | The desired new value of the field encapsulated in a parameter. |
Remarks
Examples of such changes are soundex generation and registered/last updated. In some cases the client could not care less, while the Row objects do care and need to update their internal variables to correspond to the changes that have been done. Note that you may be called about fields that were NOT part of your original query, and you will be called at least once for each changed field.
