SSRS Data Driven Subscriptions Job Names


When you create and schedule a Data Driven Subscription for a SQL Server Reporting Services (SSRS) report a job is created with a very meaningless name.  The name is actually a uniqueidentifier and is stored as such in the dbo.Schedule table in the ReportServer database.  I was recently asked if it was possible to use the Job Name to identify the Report associated with the job.  After a little digging I was able to produce the following query, which associates the Job Name with the Report Name:
SELECT
            s.ScheduleID Job_Name,
            su.Description Subscription_Description,
            c.Name Report_Name
FROM dbo.Schedule s
INNER JOIN dbo.ReportSchedule rs
            ON s.ScheduleID = rs.ScheduleID
INNER JOIN dbo.Catalog c
            ON rs.ReportID = c.ItemID
INNER JOIN dbo.Subscriptions su
            ON rs.SubscriptionID = su.SubscriptionID
The ReportServer database is a wealth of knowledge.  If you support Report Server deployments I recommend that you spend some time becoming familiar with the database schema.

Reporting Services - Data -Driven Subscription

 In Reporting Services data driven subscriptions are used to run a query on a scheduled basis which returns a list of recipients to receive a report.  What I have tried to do here is to show a simple example which will use this functionality to monitor an application and email out a report when any alerts that have been triggered. 
 
You need the enterprise version of reporting services to use data driven subscriptions. In addition SQLAgent needs to be running and the data source must use stored credentials. 
 
The example will use a simple table to hold details any events that need to be reported on. The application will insert rows into this table for each event that needs reporting on 

create table ReportTriggers(
    TriggerID int IDENTITY(1,1) NOT NULL,
    TriggerDate smalldatetime NULL,
    TriggerDescription varchar(50) NOT NULL
)
 
The stored procedure prGetReportTriggers will be queried and it will only populate the email recipient list if new records have been added to the ReportTriggers table that have not already been reported based on the fact that the triggerdate is null
 
Create procedure prGetReportTriggers
as
begin
    if (select COUNT(*) from ReportTriggers
        where TriggerDate is null) > 0
        begin
                select 'yourname@yourdomain.com' as Email
                update ReportTriggers set TriggerDate = getdate()
                where TriggerDate is null 
        end
                select NULL as Email
end        
        

The report that will be called by the subscription should use the following SQL to get those records that have just been updated by the prGetReportTriggers stored procedure.

select * from ReportTriggers
where TriggerDate = (select max(TriggerDate) from ReportTriggers)
 
Follow the following basic steps to create the data driven subscription 

 
Call the stored procedure 


Populate the To value with the returned email list

Steps to create SSH key from git bash

Generating an SSH key in OpenSSH involves a few simple steps. Here’s how you can do it: 1. Open a Terminal If you're on Linux or macOS, you can use the built-in terminal. On Windows, you can use the Command Prompt, PowerShell, or Git Bash if you have Git installed. 2. Generate the SSH Key Pair Run the following command: bash Copy code ssh-keygen -t rsa -b 4096 -C "your_email@example.com" Here’s what each option means: -t rsa : Specifies the type of key to create, in this case, RSA. -b 4096 : Specifies the number of bits in the key, 4096 bits is a good choice for strong encryption. -C "your_email@example.com" : Adds a label to the key, usually your email address. 3. Choose a File Location After running the above command, you'll be prompted to choose a location to save the key. By default, it will be saved in ~/.ssh/id_rsa (on Linux or macOS) or in C:\Users\YourUserName\.ssh\id_rsa (on Windows). Press Enter to accept the default location, or specify a diff...
