I have read many strong views (both for and against) SPs or DS.
I am writing a query engine in C++ (mySQL backend for now, though I may decide to go with a C++ ORM). I cant decide whether to write a SP, or to dynamically creat the SQL and send the query to the db engine.#
Any tips on how to decide?
I'm working in NetBeans 6.8 and I'm trying to create new connection using MySQLto an existing database. Does the .mdb file need to be in a specific location? It tells me that it cannot establish the connection.
$extension = “SUBSTRING_INDEX(domain_name, ‘.’, -1)”;
$this->db->order_by($extension, “asc”);
It says:
You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near ‘asc LIMIT 50’ at line 44
But its working when I didn’t used the $this-db-order_by Active Record Class
such as this one:
$this-db-query(“SELECT * FROM domain ORDER BY SUBSTRING_INDEX(domain_name, ‘.’, -1)”);
Anyone please help me. Thanks.
I am currently working with User objects -- each of which have many Goal objects. The Goal objects are not User specific, that is, Users can share the same Goal. I am attempting to fashion a way to calculate a "similarity percentage" between two Users... (i.e., taking into account how many Goals they share as well as how many Goals they do not share) Does anyone have experience with this type of situation? I am using Grails with Mysql if that is helpful.
Thanks

Hi, I have a mysql table that I need to only contain 20 newest records before adding additional records.
New rows are added daily so I would like it first delete any records that are greater than the 20 allowed starting with the earliest.
The table contains an auto increment "id" column so I can easily determine which is the earliest records.
Thanks for any help.

Right now on my (beta) site i have a table called user data which stores name, hash(password), ipaddr, sessionkey, email and message number. Now i would like the user to have a profile description, signature, location (optional) and maybe other things. Should i have this in a separate mysql table? or should i share the table? and why?
Is it possible to install PHP, MySQL, Apache individually on Solaris instead of installing them through a webstack? What are the advantages and disadvantages?
I seem to frequently get a CURL error on Solaris when dealing with HTTPS sites. (error:81072080:lib(129):func(114):reason(128). I have no clue why that error is occuring and thought it might solve it, if I upgrade to latest PHP,MySQL,Apache versions. At this point I am not even sure if it's a Solaris issue.
Any advice?
Thanks
It seems that if you have many tables, you can only perform a MySQLDump without locking them all, otherwise you can an error.
What are the side effects of performing a MySQLDump without locking all the tables; Is the DB snapshot I get this way, consistent? Do I have any other alternative for getting a backup of a MySQL DB with many tables?
Ok, so title says it all. Of course, I store all players' ip addresses in mysql and I can check if there is a person with the same ip address before he registers, but then, he can register to my page at school or wherever he wants. So, any suggestions?
Following is the command to fetch maximum salary form empsalary table in mysql
select max(salary) from empsalary;
but I want to fetch employee who got fourth highest from the list of employee.
I don't want to use trigger or function because I know there is direct command to fetch.
Why is it that you need to place columns you create yourself (for example "select 1 as number") after HAVING and not WHERE in MySQL?
And are there any downsides instead of doing "WHERE 1" (writing the whole definition instead of a column name)
I have a jQueryUI slider on my website that deals with price range.
I have a products table in mysql that has various entries.
I am using the slider to filter the results, but I need to set the minimum and maximum prices from the records in my database.
Should I just generate (with php) hidden fields in my html that contain the minimum and maximum and then use jQuery to obtain them? Or is there a better way of achieving this, maybe using AJAX?
Thanks
