Can be Googled easily!

Sigh, did you try Google?
Search for "parameterized query c#" and you will find everything you need. So simple.
Ok.. now i am able to create a parameterrised query...

WHERE EmPId=["empId"];

Above procebure takes a EmP Id as a parameter input and it works fine.

Now can we use the above query for disfferent tables...

Can we pass a table name as a parameter??

If you havn't noticed then queries are just a string and strings can be formatted! So before executing the queries, you can format the query dynamically in your code... use the values or tables the way you want. As long as it's a valid query it is fine. Execute it.
What you asking is so basic, I suggest you step back and learn the basics of database programming. Grab a good book or read some online tutorials.
