Used to enable or disable the Read Uncommitted isolation mode.
property ReadUncommitted: boolean default False;
Use the ReadUncommitted property to enable or disable the Read Uncommitted isolation mode. A database connection in this mode doesn't attempt to acquire a read lock on the table before reading from it. This can lead to inconsistent query results if another database connection modifies data in the table while it is being read, but it also means that a read transaction opened by a connection in the Read Uncommitted mode can neither block nor be blocked by another connection. The default value is False.
