Greg Larsen shows you how to use the Transaction ID value to identify the object_id for a deleted table.
Responsibility to Learn
“I would educate myself, and that I would never stop educating myself. It was my responsibility to keep learning.” Who said that? Albert Einstein? Da Vinci? Stephen Hawking? None of the above.

Is It Time To Stop Using IsNumeric()?

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.

Database Code Analysis
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.
Opinions and Votes

How to Read a Transaction Log Backup
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.
