This post contains a template for sending HTML tables via mail in T-SQL. A prerequisite is that you have created a Database Mail Profile. If you don’t have an email server available, you can use Gmail instead as demonstrated here.
Long running queries in a database may or may not be a problem, depending on the type of system. In a data warehouse solution, queries that runs for several minutes may be perfectly normal and nothing to worry about. But in an OLTP system, long running queries may cause performance problems. Read on to see how to monitor for long running queries in SQL Server.
Traditionally, trace flags 1204 or 1222 are used to write information about deadlock events to the SQL Server log. But since SQL Server 2012, there is a default Extended Event session running called system_health that can be used instead. Extended events are stored as XML, and in this post I’ll show a method to extract information when a deadlock occurs and store it in a regular table. By having the deadlocks stored in a table, it is possible to view the history of deadlocks in order to enhance deadlock investigations.
How to control workflows using SQL Server Agent.
Many SQL Agent jobs can be run automatically using the scheduler to run the job at specified times. But sometimes it would be better to run the job when specific criteria have been met, instead of at a specified time. For instance, when the data warehouse has finished loading.
This blog post will show how to create a job that starts and then waits / retries until given criteria are met.
Ever had the need to replace a piece of code in multiple SQL Server objects (Stored Procedure, Trigger, Function or Views)? Here’s a method to search for a string in all objects, replace it with some other code, and to finally script all changes. In other words, a method for mass editing SQL Server objects.
Just a short blog post to demonstrate the use of a WHILE loop in T-SQL, together with the BREAK and CONTINUE statements.
A script that summarizes information about SQL Agent job execution history. Much in the same way as the Job Activity Monitor, but with some additional information. Also, this script allows you to run it from T-SQL solutions.
