I don't get the 4th normal form. Multi valued dependency cannot create an anomaly , since all are non key attribute and all are dependent on primary key.
Sir maine Insert Into(emp_id, quali, age) values (111, Ma, 38) dala toh mera table phirse wo data capture kar liya Error show nehi kiya Please help sir 🙏
@@lotusamaze1142 thank you so so much sir for your kind reply 🙏 But sir now I created table like Create table emply_data ( Emp_id int identity (1, 1) primary key, Qualification varchar (max), Age int ) Abb sir emp_id k column m no example- 111 nehi enter kar paa raha hu Wo ab primary key ban chuka h, sirf qualification or age m hi data put ho raha h Please help sir🙏
@@lotusamaze1142 sir was watching your video of 2NF normalization in that you said Insert into (emp_id, qualification, age) Values (111, 'MA', 38) ; *#that part of video **violation of primary key constraint 'pk_emp' cannot enter duplicate key............ So for doing/testing it in pratical i started creating a table create table emply_data ( Emp_id int identity (1, 1) primary key, Qualification varchar (max), Age int ) In that sir when I am entering the value only qualification & age can be entered it is not accepting any no. or alphabet in emp_id.. That is my problem sir Hoped you understand sir Please help 🙏
In emp_id data type is INT so it will take only unique numbers. You can create composite Key i.e emp_Id+Qualification to make the uniqueness for the combination of emp_id and qualification
My question is if we add primary key in my 1st table there after we add foreign key my table. Here it automatically performe 2NF . I mean to say that is there any query over Normizilation.
Kisi k pass Agar waqt hai toh jawaab de dena *With increasing level of normalization kya no. Of tables increase hoti hai ya decrease? *hardware level pe dekhe toh creation of table kya 1 concept hai sirf?

Sir maine Insert Into(emp_id, quali, age) values (111, Ma, 38) dala toh mera table phirse wo data capture kar liya
Error show nehi kiya
Please help sir 🙏

@@lotusamaze1142 thank you so so much sir for your kind reply 🙏
But sir now I created table like
Create table emply_data (
Emp_id int identity (1, 1) primary key,
Qualification varchar (max),
Age int
)
Abb sir emp_id k column m no example- 111 nehi enter kar paa raha hu
Wo ab primary key ban chuka h, sirf qualification or age m hi data put ho raha h
Please help sir🙏
what is your exact requirement?
@@lotusamaze1142 sir was watching your video of 2NF normalization in that you said
Insert into (emp_id, qualification, age)
Values (111, 'MA', 38) ;
*#that part of video
**violation of primary key constraint 'pk_emp' cannot enter duplicate key............
So for doing/testing it in pratical i started creating a table
create table emply_data (
Emp_id int identity (1, 1) primary key,
Qualification varchar (max),
Age int

In emp_id data type is INT so it will take only unique numbers. You can create composite Key i.e emp_Id+Qualification to make the uniqueness for the combination of emp_id and qualification
