So as to use cursors dynamically using MySQL is it possible to declare a cursor in a loop of a stored procedure? I've tried and got an error: increment: LOOP DECLARE cur1 CURSOR FOR SELECT person_id, publication_id FROM p_publication WHERE person_id = new_count; DECLARE CONTINUE HANDLER FOR NOT FOUND SET done = 1; OPEN cur1; REPEAT ...
I've been working on this for quite some time looking for solutions in various places. I've used Nick Gravelyn's style of storing animations into a text file and am simply incrementing an index to change frames. The trouble I'm having is looping an animation once and only once, but for some reason the way that I know should work isn't wo...

I have parent child data in excel which gets loaded into a 3rd party system running MS SQL server. The data represents a directed (hopefully) acyclic graph. 3rd party means I don't have a completely free hand in the schema. The excel data is a concatenation of other files and the possibility exists that in the cross-references between...

I want to test concurrency, and reliably replicate an issue that JMeter brought to my attention. What I want to do is set a unique identifier (currently the time in milliseconds with a counter appended) and increment the counter between loops but not between threads. The idea being that the number of threads I have set up is the number ...
I am trying to write a batch script with a section that ouputs your drive mappings to a text file, so i can restore it later once i wipe out the machine. I came up with this for loop to do it, but its acting differently when its a batch script versus running the command itself. This is the actual line of code: FOR /F "tokens=1,2" %i in...

I have a level class (which contains a bunch of rooms) and a Room class. I would like to be able to do something like the following. l = Level() for room in l: ...
Is it better to declare a variable used in a loop outside of the loop rather then inside? Sometimes I see examples where a variable is declared inside the loop. Does this effectively cause the program to allocate memory for a new variable each time the loop runs? Or is .NET smart enough to know that it's really the same variable. For ex...
I'm trying to run apply a function to each row of a dataset. The function looks up matching rows in a second dataset and computes a similarity score for the product details passed to it. The function works if I just call it with test numbers but I can't figure out how to run it on all rows of my dataset. I've tried using apply but can't...

Say you are writing a 3d renderer with support for multi-texturing, where the number of texture units is configured through a compile time constant. Opposed to hard coding a single texture unit, your'e code now has to access texture-related parameters through arrays, and handle them through loops. Assuming a modern C++ compiler, are the...

I'm trying to create a php script which retries another php script up to 3 times until an error is displayed. I'm thinking perhaps this could be done using a php loop? If the code works successfully the first time, then there is no need for it to retry 3 times, however, if it doesn't work the first time, then it should retry the php scri...
