param_file_no
I don't see this declared as a variable!
Never underestimate the power of human stupidity RAH
it's passed as parameters. sorry i forgot to metion it. it's like this:
IN param_file_no int, IN param_visit_id int, IN param_v1 int, IN param_v2 int, IN param_created_user int
so what could be the reason for my problem?!

Hi, I am getting the following error on MySQL stored procedure but I can't understand the reason! can any help please.. here is the error followed by full code:

Then use what you have noted down as the input for your exists clause. Keep working through the code in this manner until you find the error - yes, debugging is tedious however the gold at the end of the rainbow is finding the error. Good luck :)

that's what I did and I got the error mentioned in my first post.

and yet what I am seeing in your code are variables such as
visit_idandparam_file_norather than the hard-coded values of these variables. I don't need to see the values but I am not sure you understand what I was trying to communicate in my previous post - basically what I am saying is run each part of the stored procedure one line at a time noting the results then run the next line - each time running the line outside of the stored procedure.“That which can be asserted without evidence, can be dismissed without evidence.”

that's exactly what I did Christopher. All lines are giving correct results with no error. The line I am having problem with is the following:
SET @param_days_since_last_visit = (DATEDIFF(DATE(NOW()), (SELECT DATE(created_date) FROM visits where file_no = param_file_noorder by created_date DESC LIMIT 1)));
That's the same line mentioned earlier.

That's your issue - you are missing a space before the
orderkeyword.“That which can be asserted without evidence, can be dismissed without evidence.”

no it's not. sorry i think it's paste issue. this is the line as it is in MySQL server;
SET param_days_since_last_visit = DATEDIFF(DATE(NOW()), (SELECT DATE(created_date) FROM visits where file_no = param_file_no order by created_date DESC LIMIT 1));

i have a feeling the problem is with the DATEDIFF but i don't know what is it..

hmm I was right :) the problem is with the DATEDIFF but I still don't know what is it.. I just used TO_DAYS instead and everything is working fine now.
SET param_days_since_last_visit = (SELECT TO_DAYS(NOW()) - TO_DAYS(created_date) FROM visits WHERE file_no = param_file_no ORDER BY created_date DESC LIMIT 1);
