GET_ALL_MODEL_CHANGE_COUNT_VALUES

GET_ALL_MODEL_CHANGE_COUNT_VALUES returns the change count values of all existing models. As the database is accessed directly here, models do not have to be loaded and the model list does not have to be up-to-date. So this command is heplful for cache implementations.

Syntax

CC "DB"
GET_ALL_MODEL_CHANGE_COUNT_VALUES [ as-map ] .

#--> RESULT ecode:intValue val:strOrMapValue

Parameters

• as-map (modifier) - if specified, the result will be a map, otherwise it will be a token string. A map is more convenient and more efficient for further processing in AdoScript. For a result of a WebSercice call working with a token string might be the better alternative.

Returns

• ecode (intValue) -
• dates (strValue) - OrMapValue; If the result is a map, the map's keys are the model IDs while the map's values are the related change count values. If the result is a token string, for each existing model the val string contains one pair (model ID, change count) whose elements are separated by a tab character ("\t"). These pairs are separated by newline ("\n"). So the complete string has the form "<modelid-1>\t<count-1>\n<modelid-2>\t<count-2>\n...\n<modelid-n>\t<count-n>".
