Sir/Madam I am trying to use regex in my database application but no success. I tried to consult books but very little info about regex is given as its a new topic, on sites it is too complex. Can anybody help me about which expression will evaluate that the user enters proper hours (i.e. 0-23) in my field.. I tried something like [0-9] | [0-1][0-9] | 2[0-3] According to wat i tried, the first part is for users who enter 9 or 8 or something secong part for users who enter 09 or 18 or etc third part for users who enter 20 or 23 or etc thus i tried to handle all types of valid inputs but it isnt working!!!
