Social media has changed everything, there were times when we used to send emails but nowadays things have changed. We all have many different ways to connect with each other. Here are a few questions which I have received on the Facebook Page in the month of the march and I am sharing a few of them here.

A: You will have to install your entire SQL Server to change collation of the server.
Q: How to recover system databases from suspect mode without having any backups? (link)
A: You need backup to recover a corrupt system database.
Q: What does *= operator does for SQL Query? (link)
A: It is an old way of using left join, now it is deprecated so avoid using it.
Q: How to reduce CXPACKET and PAGEIOLATCH_XX waits in SQL Server database? (link)
A: CXPacket is the effect of parallelism, which may or may not be a problem. PageIOLatch indicates a problem with the slowness of the disk subsystem. This would very well cause CXPacket as well. (blog, blog)
