Stored procedures
Adds a scheduled task on an HFSQL server.
Compatibility with version 12: For backward compatibility with version 12, you also have the ability to define a task via the HScheduledTask structure. This task will run the specified stored procedure (or will perform a database backup).
Example
// Describe the connection
gsCSConnection is Connection
 
MyTask is hScheduledTask
MyTask.Description = "Scheduled backup " + CR + ...
DateToString(DateSys(), maskDateSystem) + ...
" at" + TimeToString(TimeSys(), "HH:MM:SS")
MyTask.Month = "*"
MyTask.DayOfWeek = "*"
MyTask.DayOfMonth = "*"
MyTask.Hour = EDT_Time.Hour
MyTask.Minute = EDT_Time.Minute
MyTask.NumberExecution = 1
MyTask.Procedure = "HBackup"
Add(MyTask.Parameter, gsNameCSDatabase + "/LOG_TASKSFIC")
Add(MyTask.Parameter, gsNameCSDatabase + ".ScheduledBackup")
Add(MyTask.Parameter, True)
Add(MyTask.Parameter, MyTask.Description)
nID is int = gsCSConnexion.AddTask(MyTask)

<Stored procedure>: WLanguage procedure
