OK, say you want need an alphanumeric field for something like a product code, grab yourself a string datatype and add a regular expression similar to;
^[A-Z0-9]{2,10}$
In this particular example,
  1. [A-Z0-9] allows only UPPERCASE letters from A-Z OR numeric values between 0 and 9
  2. {2,10} length is restricted to a minimum of 2 and maximum of 10
Valid
  1. 12345ABCDE
  2. M12
  3. SHOES115
  4. F1DEF

Invalid
  1. 12345ABCDEF
  2. M
  3. 9
  4. f1def

  Excellent Tool ! This tool will save you a lot of time writing the same old structure. I've used others but this is really nice for a quick start. Makes a 3 hour task a 15 minute one. Thanks for this extension
