Action


Excerpt
Set or change the value of the named persistent storage table.


Parameters

Name (string): The name of the persistent storage table. Case is not significant.


Value (table): The table contents to be written to, or overwritten in, the named persistent storage table.

Append (bool; optional, default false): Whether to append to whatever is already in the table (true) or overwrite it (false). Available from v8.0 onwards.

It is not an error to append if the table does not already exist; in this situation the parameter's value is irrelevent.

Warning
There is no check that the schema of the appended rows is the same as that of those already there.


MaxRowCount (int; optional, default 1000): When appending, limit the table to this maximum number of rows. Available from v8.0 onwards.

The range is 1 to the SelectRowsLimit configuration value (100000 by default). This should be specified only if Append is true. There is no limit when overwriting.

Note
Rows already in the table are never deleted when Append is true, and MaxRowCount only affects the addition of new rows - it never truncates. For example, if the table already contains 10 rows and we try to append more with MaxRowCount set to 5, then the table will still contain just the 10 original rows at the end of the operation.


Return valuesName (string): The name of the new or updated persistent storage table.
Examples

A simple example.

Code Block
@table = Agent.GetSummary();
Storage.Set(Name: "Agent_Summary.Oct2018", Value: @table);

The method overwrites whatever was previously in the table. If you want to accumulate data by appending, these show examples of a task that would be run periodically to record who is logged on at that time. They also return the accumulated data.

Code Block
titleVersion (a) not using Append, up to v5.2
@loggedOnUsers = Users.GetLoggedOnUsers();
@newEntries = SELECT *, datetime("now") AS Timestamp FROM @loggedOnUsers;
@storageName = SELECT "LoggedInAudit" AS Name;

// Store data
@found = Storage.Check(Name:@storageName);
IF (@found)
    @currentEntries = Storage.Get(Name:@storageName);
    @newEntries = @currentEntries + @newEntries;
ENDIF;
Storage.Set(Name:@storageName, Value:@newEntries);
Storage.Get(Name:@storageName);


Code Block
titleVersion (b) using Append, from v5v8.3 0 onwards
@loggedOnUsers = Users.GetLoggedOnUsers();
@newEntries = SELECT *, datetime("now") AS Timestamp FROM @loggedOnUsers;
@storageName = SELECT "LoggedInAudit" AS Name;

// Store data
Storage.Set(Name:@storageName, Value:@newEntries, Append:true);
Storage.Get(Name:@storageName);
