Most developers and database administrators only consider SQL Server Agent when job scheduling with SQL comes to mind. While SQL Server Agent is the native tool available for Microsoft’s SQL Server, there are third-party job scheduling software solutions offering more advanced capabilities and improved task management for large teams and enterprises.
What is SQL?
SQL stands for Structured Query Language and is a programming language designed for managing and manipulating relational databases. It provides a standardized way to interact with databases and perform operations like retrieving, updating, and deleting data. SQL is widely used across different database management systems and understanding how to use it is a fundamental skill for database professionals.
Microsoft’s SQL Server is a popular relational database management system (RDBMS). It provides robust and scalable solutions for storing, retrieving, and managing data. Through a comprehensive suite of tools and services, SQL Server offers efficient ways for teams to schedule and automate jobs.
SQL Server Agent
SQL Server Agent is a built-in job scheduling and automation tool provided by Microsoft SQL Server. It allows database administrators (DBAs) to automate various tasks, including backup and maintenance jobs, data extraction and transformation processes, and other routine operations. SQL Server Agent service integrates seamlessly with the SQL Server database engine and provides a centralized platform for managing job schedules.
Scheduling Jobs in SQL Server
Database administrators can schedule jobs using SQL Server Agent through the SQL Server Management Studio (SSMS) interface. With SSMS, SQL Server Agent jobs can easily be created, modified, and managed. The process typically involves the following steps:
- Launch SSMS: Open SQL Server Management Studio and connect to the SQL Server instance for the job schedule.
- Navigate to SQL Server Agent: Expand the SQL Server instance node to find the “SQL Server Agent” node. Right click on the node and select “New Job” to create a new job.
- Configure job properties: Provide a job name and specify the owner (usually a DBO or a specific user). Define job steps to represent individual tasks to be executed as part of the job.
- Define job schedules: Set the job schedule by specifying the start time, end time or end date, and frequency of execution, such as daily frequency. SQL Server Agent offers various new schedule types, including one-time, recurring, and more advanced options.
- Set notifications: Configure notifications to receive alerts when jobs complete or encounter issues. Notifications can be received via email or other means.
- Add optional advanced job scheduling features: SQL Server Agent allows for advanced job schedule functionality to perform complex operations and automate tasks. Features include executing SQL scripts, stored procedures, PowerShell scripts, and SSIS packages as part of a job.
- Save and enable the new job: Once all the configurations are complete, save the job and enable it to activate the schedule. The SQL Server Agent service will take care of executing the select job according to the defined schedule.
To schedule a job for a SQL query for daily frequency as noted in step 4 above, take the following steps:
- Select the “Steps” page on the left-hand side of the new job window. Click on the “New” button to define new job steps.
- In the new job step window, provide a job step name in the “Step name” field,
- In the “Database” field, select the SQL server database for executing the SQL query.
- In the “Type” section, select “Transact-SQL script (T-SQL)” to specify execution of an SQL query.
- In the “Command” field, enter the SQL query for scheduling. To schedule multiple SQL queries or commands in the same job, click on the “New” button to add more job steps.
- Select the “Schedules” page on the left-hand side of the new job window. Click on the “New” button to define a job schedule.
- In the new job schedule window, add a schedule name in the “Name” field. Note the assigned Job ID (job_id).
- Set daily frequency of the job schedule by selecting the “Daily” option under the “Frequency” section. Alternatively, users can use the freq interval (daily) and
- Specify the start date in the “Start date” and the start time in the “Start time” field.
- Set an end date for the job if applicable in the “End date” field. This field can be left blank if the job should run indefinitely. Alternatively, users can use the
- Set the “Occurs once every field” to “1” to indicate the job runs on a daily frequency.
- Retrieve the schedule ID (schedule_id) for the newly created schedule.
- Save the schedule by clicking “OK”, and click on the “OK” button in the new job window to save the job.
To associate the schedule with a job using the command line, execute the following T-SQL command:
USE msdb; INSERT INTO dbo.sysjobschedules (job_id, schedule_id) SELECT job_id, <Schedule_id> FROM dbo.sysjobs WHERE job_id = <Job_id>;
<schedule_id> above with the schedule ID from step 12 above and the
<job_id> with the Job ID from step 7.
Next, execute the T-SQL command to active the job:
EXEC dbo.sp_update_job @job_id = <Job_id>, @enabled = 1;
<job_id> with the Job ID from earlier. The job is now scheduled to run according to the specified SQL script and schedule settings. The script will be executed at the defined frequency and start time, utilizing any included parameters like

Frequently Asked Questions
SQL Server offers a variety of options for scheduling type, including:
One-time: This scheduling type allows users to execute a job only once at a specific date and time. It is useful for tasks that need to be performed at a specific moment, like data import or system backup.
Recurring: This scheduling type enables database administrators to set a new job to run repeatedly at specified intervals. Jobs can be configured to execute on a daily frequency, weekly, monthly, or at custom intervals. Recurring schedules are good for tasks that need to be performed on a regular basis, like database maintenance or data synchronization.
Advanced scheduling types:
• SQL Server Agent Proxy
• On startup
• On idle
• On multiple servers

SQL Server is a relational database management system (RDBMS) developed by Microsoft. SQL Server supports various data types, including the
VARCHAR data type, which is used for storing variable-length character data. It also provides functions like
GETDATE(), which retrieves the current date and time from the system.
SQL Server 2008 refers to a specific version of SQL Server released in 2008. As an earlier version, it shares many capabilities but there are differences in syntax and functionality. One significant aspect of SQL Server and SQL Server 2008 is the concept of a schema. A schema in SQL Server is a container that holds objects like tables, views, stored procedures, and functions. It provides a logical organization and separation of database objects for enhanced management and security.
The system database MSDB plays a crucial role in SQL Server and SQL Server 2008. MSDB contains system objects used by SQL Server Agent, which is responsible for job scheduling, alerts, and notifications. It stores information about scheduled jobs, job history, job activity, and other related metadata.
Stored procedures are a vital feature in SQL Server and SQL Server 2008. Stored procedures are pre-compiled and stored database objects that encapsulate one or more SQL statements. They allow for efficient execution and reusability of complex or frequently performed tasks.
For teams not using Microsoft, ActiveBatch offers intuitive solutions for job scheduling in Windows.
