Table 2. New or changed properties
API
Change
AutoCommit
This property now has Read/Write capability.
KeyFields
This property is Read only in the DataView class.
QuerySort
When you specify sort direction in a BY phrase within this property, you can use a pseudo-keyword, TOGGLE. The setQuerySort function has internal logic to handle this word in a BY phrase. When the function finds TOGGLE in a BY phrase, the function checks the sort direction of the current BY phrase. The function applies the opposite sort direction to the new BY phrase.
Caution: TOGGLE is not a true Progress 4GL keyword. You cannot use this word in BY phrases outside the context of this function and a few related functions.
UpdatableColumns
This property is Read/Write in the DataView class, but Read only in the Data class.
