There are many sites that offer SQL tutorials and samples. You have to decide which one is 'best' according to your knowledge and ability. To become really accomplished there is no substitute for doing it. Create some databases and practice all the different commands until you are thoroughly familiar with them. See https://www.google.com/search?q=msdn%3A%20sql[^] for some of Microsofts offerings.
also don't forget that learning anything to advanced levels requires time and experience, so before you go read a bunch more theory work with it at the level you know and radually push yourself until you hit things you want to do but don't know how to
wax on wax off

I'm looking for a link redirecting script (php) or wordpress plugin that will switch links based on how many times clicked. I know its simple, and I thought it would be very easy to find but I can not find a useful tool anywhere. Thought maybe you guts could help.
I have a strange behaviour in a php script.
1. I list all files of a directry and it's subdirectories in an array.
2. I convert all names in utf-8 and put them in a second array.
3. I serialize and save both arrays in binary files.
4. I rename all files by stripping accents, spaces and all non-ASCCI characters (normalized names).
5. I unserialize the binary files in new arrays and then ...
all that I get is only the normalized names in each table.
I can't understand how this happens and how to get around.
Note: If I exit the script after 3. and rename the binary files, everything works fine in point 5. by unserializing these renamed binary files.
I would greatly appreciate any suggestion.
Thx for your time.
I think I've found a walk-around:
As at the begining I only the names in the differents formats to store in my database, I'll just get them and I'll renames the files after closing the DB.
Hope this will work. But I'm still obseded by this strange behaviour.
To lazy load the data for the expanded tree node I need to fire an Ajax request to a PHP file which gives me the answer as a JSON stream. In the example I'm trying out this PHP file only delivers one string (with 'echo'), but what do I have to do if I need to loop through a database recordset. Can I 'echo' every partial answer to my lazy loading treeview as I get it from the database or do I need to collect the complete answer inside the PHP file in a string variable and send it only when it's complete?
I am a beginner in php and I'd see a picture on the same page by validating certain criteria by pressing a button.
Here the form that I created and I would like the table appears below when I click on the button displaying statistics .
1.load the statistics and use css set display:none;button on click,
(jquery) $("id of the table").show something like that
