The last parameter to this method indicates if an autoincrement column is getting added or if the autoincrement column is being modified to change the increment value or to change the start value Parameters:   columnName - The name of the column Parameters:   columnPosition - The ordinal position of the column Parameters:   columnType - A DataTypeDescriptor for the type ofthe column Parameters:   columnDefault - A DataValueDescriptor representing thedefault value of the column, if any(null if no default) Parameters:   columnDefaultInfo - The default info for the column. Parameters:   table - A TableDescriptor for the table thecolumn is in Parameters:   defaultUUID - The UUID for the default, if any. Parameters:   autoincStart - Start value for an autoincrement column. Parameters:   autoincInc - Increment for autoincrement column Parameters:   userChangedWhat - Adding an autoincrement column ORchanging increment value or start value ofthe autoincrement column.
