Q:

The multi part identifier could not be bound is

Answer

One of the most common errors that you might face in join statements is 


 


Server: Msg 4104, Level 16, State 1, Line 1
The multi-part identifier could not be bound.


 


A multipart identifier is any description of a field or table that contains multiple parts - for instance MyTable.SomeRow - if it can't be bound that means there's something wrong with it - either you've got a simple typo, or a confusion between table and column. It can also be caused by using reserved words in your table or field names and not surrounding them with [].


 


The main reason for this error is that the source table cannot be found, for example if you have statement such as Table1.OrderDate, and then if you get error above, this means that Table1 cannot be found in the query. Sometimes you can see that source table exists in the query, but T-SQL cannot understand it, especially when you write join statements.

Q:

You are a tester. Now How will you choose which defect to remove in 1000000 defects?

Answer

First thing testers are not responsible for fixing the bug they are only responsible for debugging the bug and prioritizing those bugs. These bugs are now reported in bug report template with the severity and priority of the bug. Tester assigns severity level to the defects depending upon their impact on other parts of application. Every bug has its severity and priority values assign by tester. If a defect does not allow you to go ahead and test the product, it is critical one so it has to be fixed as soon as possible. We have 5 levels as:


 


Critical


High


Medium

Cosmetic
