For example, in the first run with caching on this query might take 30s: $ dsq some-large-file.json --cache 'SELECT COUNT(1) FROM {}' But when you run another query it might only take 1s. $ dsq some-large-file.json --cache 'SELECT SUM(age) FROM {}' ...
Similarly, the value of the 4throw of the RunningAgeTotal column is 49, which is the sum of the values in the 1stto the 4throws of the StudentAge column. In the SQL Server, the OVER clause can be used to calculate running totals. ...
To sum up, SQL Server Agent (2000) can start a maximum of 60 jobs a minute, as it explicitly imposes a one-second delay between starting jobs. By manually tweaking some registry settings, however, you can modify the number of maximum concurrent agent jobs, which is also covered in ...
This example illustrates how to create a simple SQL Server unit test. In a real-world database, you could sum the total amounts of all orders with a status of 'O' or 'F' for a particular customer. The procedures in this walkthrough also contain no error handling. For example, they ...
