How do I run two stored procedures in parallel?

How do I run two stored procedures in parallel?

You have to create as many separate jobs as you want parallel processes running, even if they are running the same stored proc with different parameters. SSIS Package: Create an SSIS package with a simple branching task flow. SSIS will launch those tasks in individual spids, which SQL will execute in parallel.

How do I run a PL SQL procedure in parallel?

Answer: Oracle has a wealth of parallel features including parallel query, parallel DML, but it is also possible to perform parallel processing on Oracle using PL/SQL. You could place each on in a separate stored procedure and then use the UNIX/Linux “nohup” command to submit them in parallel. dbms_job.

How do you Optimise stored procedure in SQL Server 2005?

Improve stored procedure performance in SQL Server

1. Use SET NOCOUNT ON.
2. Use fully qualified procedure name.
3. sp_executesql instead of Execute for dynamic queries.
4. Using IF EXISTS AND SELECT.
5. Avoid naming user stored procedure as sp_procedurename.
6. Use set based queries wherever possible.
7. Keep transaction short and crisp.

How do I run a SQL query in parallel?

To achieve parallelism for SQL DML statements, you must first enable parallel DML in your session: ALTER SESSION ENABLE PARALLEL DML; Then any DML issued against a table with a parallel attribute will occur in parallel, if no PDML restrictions are violated.

How do you run a procedure in parallel?

Execute Stored Procedures in Parallel

1. Define the stored procedure as a static method of a class in a language supported by the .
2. Register the assembly in SQL Server by using the CREATE ASSEMBLY statement.
3. Create the stored procedure that references the registered assembly by using the CREATE PROCEDURE statement.

How do you write multiple queries in one stored procedure?

Executing Multiple SQL Statements in a Stored Procedure

1. A classic DBA technique to run a large number of SQL statements is to create them using a concatenated select statement.
2. If you need to drop a handful of tables that way, a list if enough.

How is parallel processing implemented in application engine?

To use parallel processing, partition the data between multiple concurrent runs of a program, each with its own dedicated version of a temporary table (for example, PS_MYAPPLTMP). If you have a payroll batch process, you could divide the employee data by last name.

How do I add parallel hints in Oracle?

Oracle Database Hints Parallel Hint SELECT /*+ PARALLEL(emp,8) */ first_name, last_name FROM employee emp; SELECT /*+ PARALLEL(table_alias,Degree of Parallelism) */ FROM table_name table_alias; Let’s say a query takes 100 seconds to execute without using parallel hint.

Can I use CTE in Stored Procedure?

According to the CTE documentation, Common Table Expression is a temporary result set or a table in which we can do CREATE, UPDATE, DELETE but only within that scope. That is, if we create the CTE in a Stored Procedure, we can’t use it in another Stored Procedure.

How can reduce execution time of Stored Procedure in SQL Server?

There are several ways by which you can speed up the execution timing of a stored procedure.

1. use SET NOCOUNT ON :- when you include this statement inside of your stored procedure it will reduce the Network traffic between server and the client.
2. Avoid using sp_ at the start of your stored procedure name.

What is parallel execution?

Parallel execution is the ability to apply multiple CPU and I/O resources to the execution of a single database operation. It dramatically reduces response time for data-intensive operations on large databases typically associated with decision support systems (DSS) and data warehouses.

What is parallel plan execution in SQL Server?

Executing a query with a parallel execution plan means that multiple threads are used by SQL Server to perform the necessary operators from the execution plan.

Why does SQL Server run stored procedures in parallel?

The reason for this is that the procedure takes around 7 hours to complete. It actually does the same process many times. So for instance it might build a new database and tables for each branch. What I want to do is break down the stored procedure so I can run in per branch but then run each query in parallel.

Is it possible to execute multiple SQL statements in parallel?

Sure it’s possible to execute statements parallel but I see no chace to start 10 procs parallel. Do a UNION statement, that may execute it’s parts shared on more CPU’s. Please share your statements to get more suggestions.

How long does it take to run Proc _ allsps in parallel?

If there is any other way that all the procedures run parallelly, then the procedure “proc_AllSPs” can run in 5 seconds time. Sorry if I am not being elaborated.

Which is an example of asynchronous execution in SQL?

OLE Automation: In SQL, use sp_oacreate and sp_oamethod to launch a new process calling each other stored proc as described in this article, also by Gregory A. Larsen. Service Broker: Look into using Service Broker, a good example of asynchronous execution in this article.
