Lesson Learned #336: Using STARTUP_STATE option in an extended event in Azure SQL Database
Introduction
Azure SQL Database is a fully managed, intelligent cloud database service. It has a wide range of features that allows developers and administrators to optimize their databases for performance, scalability, and cost. One of these features is the ability to use extended events in Azure SQL Database. In this blog post, I’ll discuss how to use the STARTUP_STATE option in an extended event in Azure SQL Database.

What is an Extended Event in Azure SQL Database?
An extended event in Azure SQL database is a feature that allows you to collect events from the database in a structured way. It provides an easy way to collect data from the database and store it in a database table. This data can then be used for troubleshooting, monitoring, and performance analysis.

What is the STARTUP_STATE Option?
The STARTUP_STATE option is a feature in extended events that allows you to capture events that occur during database startup. This can be useful for troubleshooting, performance analysis, and monitoring. The STARTUP_STATE option ensures that the extended event captures events that occur during the startup process, including connection attempts and database initialization.

How to Use the STARTUP_STATE Option
The STARTUP_STATE option is used in extended events in Azure SQL Database. To use it, you must first create an extended event session with the STARTUP_STATE option. You can do this using T-SQL or the Azure portal. Once the session is created, you can begin capturing events during the database startup process.

Example
Below is an example of a T-SQL statement that creates an extended event session with the STARTUP_STATE option. The session will capture events related to database startup:

CREATE EVENT SESSION [My_Session]
ON SERVER
ADD EVENT sqlserver.connect_attempts
ADD EVENT sqlserver.database_startup
WITH (STARTUP_STATE = ON)
GO

Conclusion
In this blog post, I discussed how to use the STARTUP_STATE option in an extended event in Azure SQL Database. The STARTUP_STATE option allows you to capture events that occur during the database startup process. This can be useful for troubleshooting, performance analysis, and monitoring.
