RE: Script to Disable Constraint, Change Value, then Enable Const

[Hallas John]

Well said Mark. David, you could also re-able the constraint 'novalidate' if you wanted to ignore the validity of any new input. If that was the case then why have an integrity constraint in the first place?   John -----Original Message----- From: Mark Leith [mailto:[EMAIL PROTECTED]] Sent: 28 November 2001 10:20 To: Multiple recipients of list ORACLE-L Subject: RE: Script to Disable Constraint, Change Value, then Enable Constrain How could this be user proof? You are essentially disabling the constraint that WILL enforce data integrity, then letting the user input whatever rubbish he wants to, and are then going to try and enable the constraint afterwards?   Not a good approach.. How can you ensure that the user hasn't put a duplicate value in (unique constraint) or something else that might break the constraint rule? The only way you are going to know is when you try and re-enable the constraint it will fail..   I struggle to see why you would want to do this - do you have any more info? -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED]]On Behalf Of David Wagoner Sent: 27 November 2001 21:30 To: Multiple recipients of list ORACLE-L Subject: Script to Disable Constraint, Change Value, then Enable Constrain Listers,   Does anyone have a script that will do the following:   Accept user input for old data value Accept user input for new data value Disable table constraint Update record with new data value Enable constraint   A script like this would help ensure that constraints are not left “off” after updates, allowing “illegal” data into the tables.  Good user-proof script I would think.     TIA,   david   David B.
