启动多个存储过程以在SQL Server Express Edition上“在后台”运行

Question

Is it possible to run multiple stored procedures that run 'in the background'?

The stored procedures must be launched from a single, master stored procedure , in the same way that multiple worker threads are spawned. For example:

CREATE PROCEDURE MyLauncher
AS
BEGIN
    BEGIN
      @EXEC MyBackgroundSP01 -- Runs in parallel to the other 2
      @EXEC MyBackgroundSP02 -- Runs in parallel to the other 2
      @EXEC MyBackgroundSP03 -- Runs in parallel to the other 2
    END
END

Answer 1

It is possible in SQL 2005 and later. Have look at http://rusanu.com/2009/08/05/asynchronous-procedure-execution/

Answer 2

No this isn't possible as you have described it. You could run multiple SQL Jobs which will execute the procedures concurrently/

Answer 3

IF both Stored procedure have same parameter then you can create a new store procedure like

create third procedure
(@colname int)
as
 begin

exec first procedure
exec second procedure
end

exec third procedure

You can try it. I am sure how appropriate it is.

Answer 4

According to this question you could try using the Service Broker

Asynchronous Stored Procedure Calls

Answer 5

如果以相同的过程运行它们，它将在相同的线程中启动（并在相同的内部事务中运行，这会使日志很大）。

Answer 6

Not with pure T-SQL. But you could write a little dotNET app to run them asynchronously easily enough, as long as you leave the connection option until all three are finished.
