How to Configure cost control for serverless SQL pool in T-SQL

To configure cost control for serverless SQL pool in T-SQL, you need to execute one or more of the following stored procedures.

sp_set_data_processed_limit
	@type = N'daily',
	@limit_tb = 1

sp_set_data_processed_limit
	@type= N'weekly',
	@limit_tb = 2

sp_set_data_processed_limit
	@type= N'monthly',
	@limit_tb = 3334

The current configuration execute the following T-SQL statement:

SELECT * FROM sys.configurations
WHERE name like 'Data processed %';

 How much data was processed during the current day, week, or month, execute the following T-SQL statement:

SELECT * FROM sys.dm_external_data_processed

For example, in case new query is executed, where weekly limit is set to 1 TB and it was exceeded, the error message will be:

Query is rejected because SQL Serverless budget limit for a period is exceeded. (Period = Weekly: Limit = 1 TB, Data processed = 1 TB))
