Question

I have a Table Reminder, Messaging and Users. I have to implement that whenever a row is created in the Reminder table then the Administrators from the Users table will get message in their Messaging table.

I am doing everything inside the sql query. I have reached till the inserton and selection of all admin users, also I am able to run a loop on the number of records. I want to insert one by one in a loop.

If @flag=1 // flag=1 means reminder is created successfully
BEGIN
 Declare @BackUpMessage as varchar(200)
 Set @BackupMessage = 'Hi Admin,\r\n
 \t A backup has been scheduled by the system. Details are given below: \r\n
    a) Bakcup Type : '+rem_type+' \r\n
    b) Backup Date : '+ Convert(varchar,GETDATE()+@days)+''
                    
 Set @Count = (Select Count(*) From JFPUsers Where RoleId=1 and Active=1) // Total Numbers of Admin
 IF @Count > 0
    Declare @i int =0

    Select Id From JFPUsers Where RoleId=1 and Active=1 // Getting Id of each admin to save
    While @i < @Count
    BEGIN
        Insert Into JFMessaging (MessageBody, SenderId,RecieverId,IsRead,SentOn,IsActive)
        Values(@BackUpMessage, -1, ,0,GETDATE(),1) // I am stucked here 
    END
END

I can do it easily using C# but I want to do these stuffs in a single connection and in a single hit @ backend .

Update : See Image and the summary

Summary : What I need is whenever a record is created in reminder. The query will pick all admin from JFPUsers {condition RoleId=1 is admin} and create that much row in JFMessaging where SenderId will be the user creating reminder or -1 (for system) and RecieverId will contain the admin id with a custom notification message.

Answer 1

Create an INSERT trigger on your Reminder table that does an INSERT into the messages table for administrators. Try to get out of the habit of using loops in SQL – it is usually bad practice.

Something like this…

insert JFMessaging (ReceiverID, Otherfields)
select UserID, otherfields
from
    inserted
        cross join
    JFPusers
where RoleID = 1
