Random Numbers


Bethel SD

Recommended Posts

As part of maintaining our districts phone system we have to maintain long-distance authorization codes. In the past, the numbers were simply ran through a database and each code was increased by one. Needless to say, our staff figured it out.

 

I'm now using the random number generator in FileMaker; however, I'm noticing that some of my numbers have preceding zeros. Is there anyway to customize random numbers in terms of if it should or should not contain a preceding zero, length, etc.?

 

Thank you ahead of time for your response.

Script = Set Password

 

Show All

Go to record request first

Loop

Set Field [Password_Field, Right("0000" & Random* 9999, 4)]

Go to record request next [exit after last]

End loop

 

This will set a 4 digit random number if 5 digit

do this for Set field

 

Right("00000" & Random* 99999, 5)

Thank you for the reply. Your solution worked well for the most part, but I still received preceding zeros -- this is a problem because our phone system doesn't recognize preceding zeros when long-distance phone codes are entered.

Password Checker = calc = Case(Left(Password,1)=0,1& Right(Password,4),Password)

 

Use Password checker instead of Password

 

Callc if leading zero replace first character with 1 and use last four characters of password, Else use entire password.

 

Odds of duplication by replacing 0 with 1 depends on number of users.

If you just want to strip off any leading zeros, then the TextToNum( ) function will do that quite effectively.

 

For example, TextToNum(00005) will return 5.

 

However if, as Chopper has assumed, you want to replace the leading zeros with some other number or character, you could use:

 

Right("111111111" & TextToNum(YourNumber), Length(YourNumber))

 

...which will return 11115 when 'YourNumber' is 00005, and will return 11555 when 'YourNumber' is 00555 etc. In other words, it will dynamically replace multiple leading zeros. wink.gif
