How to pass tablename as parameter in SP to add another col?

Question

 Hi, Please help me to solve this. 

 

I have three 3 tables with some data and column names are same.

 

June_2018(table name 1)

 

id Name

1 Critical

2 Major

3 Critical

4 Minimum

5 Major

 

 

July_2018

id Name

6 Critical

7 Major

8 Critical

9 Minimum

10 Major

 

August_2018

id Name

11 Critical

12 Major

13 Critical

14 Minimum

15 Major

 

I need a stored procedure where tablename should be passed as the parameter then

Critical, Major should be as Major  as another column and Minimum should be updated as  Minimum. Expected output should be as follows.

 

Exec procedurename(Tablename as parameter) 

 

id Name    Staus

1 Critical    Major

2 Major      Major

3 Critical     Major

4 Minimum    Minimum

5 Major       Major

 

 Thanks in advance.
