I'd do the line of EXIT WHEN then add the DBMS_OUTPUT.PUT_LINE to avoid repeating values for the last execution

absolutely..this is the right way to retrieve values.

For anyone with doubts why there is an extra row printed out at last. here is the answer: as mentioned in the video, curse_name%NOTFOUND returns false when the PREVIOUS FETCH returns a row. If false, after each fetch, SQL will give the value to the variable v_name , and then, print out the v_name; ........ when the cursor coming to the last tuple, fetch statement will give the last value to v_name; then print out v_name; Notice at this time, %NOTFOUND returns false because there is a row, the last row, so loop one more time. this time, fetch statement will not give anything to v_name, v_name stays the same as last time, which is the last row, then print out v_name AGAIN; this time, %NOTFOUND returns true, terminate the loop. to avoid this scenario, you can put exit when %notfound between fetch statement and print out, instead of putting it at last line. also you can use a while loop FETCH cursor_name into v_name; while cursor_name%NOTFOUND LOOP DBMS_OUTPUT.PUT_LINE(v_name); FETCH GET_CURSOR INTO v_name; end loop; close cursor_name; end;

begin DBMS_OUTPUT.PUT_LINE('thank you so much for giving the solution to the problem'); end; /
hello mr.sharma love your channel helped me a lot in my studies i have a question. at 4:34 why Bruce is repeated ? i
Luis Fernando Guzman (8 months ago)
Check The ming answer. I have put the exit when before the DBMS_OUTPUT and the line is not repeated.
santhosh kotagiri (1 year ago)
The print output statement will be after the exit condition, otherwise the last row is duplicated.
Simmlex (1 year ago)
So... Why is this thing useful? You can achieve the same result with a simple 2 line SQL code.
Luis Fernando Guzman (8 months ago)
i guess because you can execute functions or another actions with the result of the cursor.
Pranav Srivastava (1 year ago)
Could you please explain why your output returned 'Bruce' twice in your result?
Hi, because the result statement on the screen is after the statement of the end of the cycle. Therefore, the cursor displays output 2 times.It is necessary to swap the 12 and 13 lines of code. First comes 13 line, and then 12.

Hi Manish.....no doubt it is awesome....if you can also upload a video related to the use of cursor I. e. why when to use it and it's benefits...it would be wonderful.....thanks a lot.....it helps a lot....thanks again...

Hi Manish, while i am trying to connect to the HR schema the below error is getting can you suggest me how to solve that? "Invalid connection operation operation specified and verify the URL format for the specified driver" Thanks Uttam

The print statement will be after the exit condition, else the last row is getting printed twice. :)
Pal Ayoub (2 years ago)
Amazing tuto! I think, the exiting statement is better to be placed right after the FETCH statement so the last output ligne doesn't get duplicated.

Mohit Saxena (2 years ago)
sir why there are 2 bruce in the output?? the exit when statement should be written after the fetch statement..
santosh chary (2 years ago)
hello Manish...if you write an example code for user handling exception with a wonderful example like which you have given in other sessions then that is also very useful for many..... :)

Sir, we can get the data in table by simply writing a select query then what is the advantage of creating cursor.

Sir, we can get the data in table by simply writing a select querry that you wrote then what is the advantage of creating cursor.
Sameer D (1 year ago)
As Manish explained, even when you write a simple query, Implicit cursor is created. But you will not have control over that cursor. If we need to control the cursor (like storing values in variables and manipulating them in a complex manner, like using loops, IF ELSE conditions, etc.), then we can declare an explicit cursor.

Arun kumar Dachepalli Cursors becomes handy when you are dealing with records in the millions......look up Google for more information
