Regex constraints

#1

Hello,

I am trying to set up a constraint that requires a user to enter a 3-
digit integer within the range 001-999. This is the expression I've
used:

.

However, 0 does not seem to register as an integer, so it will not
allow me to enter a number between 001 and 099, but will allow 100 to
999.

Can anyone please help me solve this issue?

Many thanks.

However, 0 does not seem to register as an integer, so it will not
allow me to enter a number between 001 and 099, but will allow 100 to
999.

How about /^(00[1-9]|[1-9]\d{2}|\d[1-9]\d)$/

Then you don't need the gt/lt stuff.

...But you should be storing this as a string and using a text data
type. Otherwise the leading 0's will be truncated.
