AlterLog(OldLog: ILog);
OldLog is the log, structure of table of which should be updated according to the structure of current log.
The AlterLog method updates the OldLog log table structure on a database server according to structure of current log.
Executing the example requires two logs with the Log_1 and Log_2 identifiers in repository.
Sub UserProc;
Var
MB: IMetabase;
Log, OldLog: ILog;
Begin
Mb := MetaBaseClass.Active;
Log := Mb.ItemById("Log_1").Edit As ILog; // log, which structure will be used for update
OldLog := Mb.ItemById("Log_2").Bind As ILog; // log, which structure on database server will be updated
Log.NativeName := OldLog.NativeName; // set equal physical names temporarily.
// it is required for saving uniqueness of physical name of OldLog log
Log.AlterLog(OldLog);
End Sub UserProc;
After executing the example, the structure of the log table on database server, referenced by the repository log Log_2, is updated. The structure is set according to the table structure, referenced by the repository log Log_1.
