It seems something went awry with the SQL Server. It’s sluggish, behaves erratically, produces heavy network traffic, there is a significant increase in the server processor or memory utilization, and to top it all there are reports of or database objects and data being damaged or missing.
“I’ve mistakenly deleted/updated important records in a SQL Server table. Is there any way to get these records back?”
This is a frequently asked question, and very often a headache for DBAs. If they are careful and make regular database backups, they can recover the lost database data even where the SIMPLE recovery database model is used
If that is the case, then database backups are the only solution to recover the lost database data. The deleted data has to be from the period prior to the database backup creation
The SQL DBA’s worst nightmare is the loss of data due to their own mistake. It’s not uncommon for someone to improperly execute or even forget a WHERE clause entirely when executing DELETE or UPDATE queries, resulting in potentially millions of rows of compromised data
So, which SQL Server data recovery options are available?
Integrating SQL Server with business infrastructure often requires that developers prepare T-SQL code for use within various client codes, such as C#, PHP, and Perl. This means adding language specific code that will be inserted before and after every SQL statement, as well as escape characters for quotes and code to terminate a line, so that the other languages can parse and execute it correctly. Updating the code manually is a time-consuming process prone to mistakes.
