In this blog post we are going to leave about how to Speed Up Performance Without Code Change or Configuration Change in SQL Server.
Interview Question of the Week #027 – Move TempDB from One Drive to Another Drive When Low Disk Space
Here is one of the important interview question which is related to TempDB and how to Move TempDB from One Drive to Another Drive When Low Disk Space.
What Is a Data Type, and Why the Wrong One Costs You
A data type decides what a column holds, what it costs in bytes, and how SQL Server compares it. Why NVARCHAR doubles your storage, why float will not compare cleanly, and the conversion that quietly kills an index.
What Is tempdb, and Why Everyone Shares It
tempdb is one scratch database shared by every database on the instance. The three kinds of thing that land in it, why it is rebuilt at every restart, and the reason its file count keeps coming up.
SQL Server on a Virtual Machine: What Actually Changes
SQL Server on a virtual machine cannot see the host it is sharing. Why more virtual processors can be slower, what memory reservation buys you, why snapshots are not backups, and the four things I check first.
What Is a Deadlock in SQL Server?
A deadlock in SQL Server is two sessions each holding what the other needs. I caused one on purpose and read error 1205. Why it is not the same as blocking, who gets killed, and the boring fix that works.
What Is a Cursor in SQL Server, and When to Avoid One
A cursor in SQL Server took 260 milliseconds where one SELECT took 4. Why the gap exists, how to turn a loop back into a set, and the three cases where a cursor really is the right answer.
