• How to generate a single random number in a MySQL database

  I create a volunteer and also a separate request form from the seller for an air show. The volunteer and seller info is stored in separate tables in MySQL db, a line by volunteer or the seller. There will be about 100 volunteers and 50 sellers. When the request should immediately be printed by the applicant signed and mailed in. This year we had problems with some people who do not immediately print asked, so I would still give them the possibility to print immediately, but also to send them an email with a link to their specific line in the MySQL database. I have an AutoIncrement primary key for each table field, but I think to send this key to the applicant in an email would be too easy for them to guess a different id and access the information of others.

  I think I should add a column for each table containing a unique random number and then I would send this key in the e-mail to the applicant. So, can anyone suggest a simple way to do this or suggest a better way to give the applicant a way to access their own request and nobody elses not after submitting their form?

  Thank you all.

  In your code, you should:

   VALUES (%s, %s, %s, %s, %s, %s, %s, %s, %s, %s, %s, %s, %s, %s, %s, %s, %s, %s, $s)",
  

  Change the $s to %s and that should solve the problem for you.

  Let me know.  Thank you!

• How can I generate multiple unique random numbers?

  Hello

  I am trying to generate multiple random numbers between a given set of numbers (1-52) and do not have the same number generated twice within this group. I can compare the numbers of last and next with the function to compare, but how would I go about comparison of all numbers generated without using a huge list of shift registers...

  Any help/ideas are welcome and appreciated.

  Solved my problem. IM passing the random number through a registry to offset to each case and build a table every time. I then searches the table for the new random number. If the number is not found I get a value of-1, another thing is an index value of 0-everything. If a comparator greater than (-1) indicates that the same number is in the table and then I can raise this matter until the same number is not found.

  Kind regards

• How can I get the 6 digit number to associate my watch.  It doesn't give me a 5-digit number?

  When I try to manually associate my watch it only gives me a 5 digit number, but not the number 6 to complete the pairing.  How can I get the 6 digit number?

  Hello

  When pairing manually, you must press the name of 5 digits on the screen of your iPhone (when he shows the same device name that is shown on your watch, after typed it on your watch's 'i'):

  

  Your watch then displays a six-digit code, you will then enter on your iPhone:

  Hi Aron,

• I don't have my key code for windows. My dealer doesn't have either. How can I retrieve the key code number?

  I don't have my key code for windows (registration card was not with the computer when I bought it).  My carrier apparently deleted the key during my computer repair code.  My retailer where I purchased the computer didn't either.  How can I retrieve my key code number?

  The Windows product key is usually displayed on the sticker on the underside of the computer.

  However, you can also get it by running the Belarc Advisor or the Magic Jellybean Key Finder.

  Google for one of those and you will find them.

  but, if you only do this several times, you can use this procedure instead:

  Open a command prompt in your folder music [shift-right click on the name of the folder in the Windows Explorer & select a window of commands here]

  Run the dir/ad/b /s > AlbumList.txt

  Then open the text file in Word and he put away: -.

  Replaceyourusernamewith Nothing \Music\ C:\Users\

  Replace-with ^ t [the code of the tab]

  Select all, convert table to use the trademarks of the tab as column separators

  Select column 1 [the artists], and delete

  If there is garbage in all 3 columns - go just delete the columns thus

  That should leave a unique list of album names
