Error: 'object could not be found' or 'invalid object name'?

As a Developer i thought you may experience one of two errors frequently, even though you thought the object already exist. The error like below:

Msg 208, Level 16, State 1, Line 1
Invalid object name 'Table/View Name'.

OR

Msg 2812, Level 16, State 62, Line 1
Could not find stored procedure ''.






Solution:
To Avoid Such type of error keep in mind always the following considerations:

1. The connecting user does not have SELECT, UPDATE, INSERT, DELETE, EXEC permissions on that object/objects.

2. your are logging/connecting as a different user that you have expected.

3. Referencing the object without an owner name prefix may raise this error;

4. your connected database is wrong;

5. May be you have written wrong object name or spelled incorrectly.
