Description.  This method is used to add a column on which events should be detected. The column may be indicated either by its ID or its name.


You must invoke Dictionary::createEvent() before any errors will be detected. See Section, “Dictionary::createEvent()”.


If you know several columns by name, you can enable event detection on all of them at one time by using addEventColumns(). See Section, “Event::addEventColumns()”.

Signature.  Identifying the event using its column ID:

void addEventColumn
      unsigned attrId

Identifying the column by name:

void addEventColumn
      const char* columnName

Parameters.  This method takes a single argument, which may be either one of the following:

  • The column ID (attrId), which should be an integer greater than or equal to 0, and less than the value returned by getNoOfEventColumns().

  • The column's name (as a constant character pointer).

Return value.  None.
