_RowState Column

The reserved column name _RowState represents the non-persistent state associated with each table row in an installer database table. The pseudo-column is of type Integer, and the value consists of a set of bit flags. All the bits are readable, but only the UserInfo and Temporary bits can be set. This data is available only as long as the tables are locked or in use (that is, while a view containing the tables exists). The following table shows the attributes a row can have.
