QuickProp Keyword Abbreviation

Remarks

This property is crucial and mandatory to the Editing functions. The table name and criteria fields are used to construct or guess various SQLs. Bookmark enables a unique criteria to guarantee that the correct record is being edited. The classic ASP alternative was either to use recordset to modify a record in which is not accurate or to demand an Autonumber field to identify the record (DB product like Oracle has no Autonumber). A side note is that - this is why the transition of ASP-db to ASP-db.Net is so smooth as this bookmarking structure is generic and can be adapted to any changes in the future.

Example

* To Use only Column 0 as key - dbBookMark = "Table;0"

* To Use Columns 0, 1, 3 as key - dbBookMark = "Table;0+1+3"

A key is a combination of columns that uniquely identify the row.
