Property Integer piPrimaryIndex
|Read Access:||Get piPrimaryIndex to IntegerVariable|
|Write Access:||Set piPrimaryIndex to IntegerVariable/Value|
This property defines which index is used to generate the record ID as it is used in WebApp state hashes.
This should be a unique index. Multi-segment indexes are allowed.
Note that the values of the segments in this index will be used in the state hashes and can appear in the URL.
If the default value of -1 is used, it will use the DF_FILE_PRIMARY_INDEX attribute. That means that it will use recnum for the embedded database and the primary key for SQL databases.
