     35Experiment conducted (Jeff):[[br]]
     36Went into the database and chose to update a column in the Onyx metadata table for the Briccs project...[[BR]]
     37update onyx set c_COLUMNDATATYPE = 'N' where c_name = 'history_AF_onset' ; [[br]]
     38Went into the workbench and refreshed the ontology tree. Dragged the history_AF_onset leaf into a group. [[br]]
     39It would not allow me to set a value ('Set value...' was greyed out / disabled). [[br]]
     40Being neurotic, I then tried: [[br]]
     41update onyx set c_operator = '=' where c_name = 'history_AF_onset' [[br]]
     42Restarted the workbench just to be sure. No change![[br]]
