Although Azure is the obvious Cloud service to host SQL Server, Amazon Relational Database Service (RDS) for SQL Server is a good choice when your organisation uses AWS. RDS deals with maintenance and monitoring, and supports the use of PowerShell to automate routine tasks. What if a script needs to be triggered by an unscheduled event? Even in this case, RDS can be configured to run scripts to react when something like a failover happens. Laerte Junior shows how easy it is to set up Lambda functions and some PowerShell scripts to automatically synchronise agent jobs after a failover.

One of the most glib generalisations you can make about development work is to say that code should be liberally commented, or conversely that it should never be commented. As always, the truth is more complicated. There are many different types of comment and some types are best treated firmly with the delete key, where others are to be cherished and maintained assiduously. Even though it is hard to find two developers who agree on the topic of commenting, Michael Sorens warily sketches out the issues and the battleground.

Even so, there are ways of expressing SQL Queries and data manipulation in ways that make it easier for the database engine to turn into efficient action. and easier for your colleagues to understand. Robert Sheldon homes in on data querying and manipulation and makes suggestions for team standards in SQL Coding.

The old system function IsNumeric() often causes exasperation to a developer who is unfamiliar with the quirks of Transact SQL. It seems to think a comma or a number with a 'D' in the midde of it is a number. Phil Factor explains that though IsNumeric has its bugs, it real vice is that it doesn't tell you which of the numeric datatypes the string parameter can be coerced into, and because it doesn't check for overflow. Phil comes to the rescue with a couple of useful alternatives, one of which works whatever version of SQL Server you have, and which tell you what datatype the string can be converted to.

Database code analysis will reduce the number of 'code smells' that creep into your database builds. It will alert the team to mistakes or omissions, such as missing indexes, that are likely to cause performance problems in production. It will allow the Governance and Operations team visibility into production readiness of the code, warning them of security loopholes and vulnerabilities. William Brewer describes the two technical approaches to database code analysis, static and dynamic, and suggests some tools that can help you get started.

The transaction log backup is stored in SQL Server proprietary format, just like the transaction log itself. Even though the transaction log backup is in a special format, Microsoft has provided us with the fn_dump_dblog() function to read transaction log backups. This function is undocumented, so you should use care when using this function in a production environment.
