Below examples considers the default ISOLATION level “READ COMMITTED” Locking: Lock: Basically when we talk about relational database, data is stored in tables. Internally a Table is represented using Pages. A lock is a memory structure which is issued by a transaction / session on a resource.

How to know the number of instances present in a machine with T-SQL query..?
Hi Ratnakar, I am really not sure how to get number of instances from T-SQL. We can do it using SQLCMD or from T-SQL XP_CMDSHELL. But we are not supposed to do that as it’s a security concern. There are 3 ways that we can get the instance details 1. SQLCMD – L or OSQL -L will give you all sql instances in your network. 2. Powershell script 3. Registry values But remember these might be different for different kind of instances (32 bit and 64 bit). Earlier we had a situation to prepare a server and database inventory and… Read more »

I am Manish. I had done BE(CSE) in 2014. I am working as database developer.
I have 1.4 years of exp in this field. I have good knowledge of SQL queries ,now i want to switch from her . I request u to please help me to make my resume better because i have no idea about making experience resume for database developer.
I have created but that one is not good enough to get selected for interviews . so please i request u to help me to make my resume better .
Hi Manish, You didn’t mention why you need a switch from the current position. If it’s not mandatory to jump from the current place then I would strongly suggest to continue with the current position at least for the next one year. There are reasons behind that when you observe the corporate world then most of the MNC’s consider people with 2 years experience as a trainee and there will be no much difference between a fresher and trainee. Or if it’s a mandate situation that you need a move now then try to build a proper resume. There is… Read more »

DBA’s role has been changing from day to day, in early days DBA used to be responsible for taking ownership of a specific RDBMS (SQL Server / Oracle / DB2 / MySQL etc.) and handling all database administrative activities but now a DBA should be able to drive the show, he / she should be expertise in database administration and should know something about everything. Let me clarify the statement, let’s say you are working as a DBA and supporting an application stack which involves a lot of sub applications, web-services, multiple RDBMS, different layers of data processing and all… Read more »
