The data is in conflict with the integrity constraints defined for the database.

Startbeitrag von Clarion Ghost am 06.05.2012 10:00

I am get the warning message "The data is in conflict with the integrity constraints defined for the database." because I am trying to delete a record which has child records.

I would like to display my own 'You can't do this' message before my 'Delete' Form appears.

How may I do this please?

Many Thanks


HOnError() is your friend. Take a look at the help for this one.

Before you do the delete() seek the record for child records. If a record has chield records ( orderline ) desplay an error() followed by a retrun ( will stop the proces )

Or Something like this, get all orders that donnot have a child and delete them.

For all orders where order.orderlineid Orderline.orderlineID
Hdelete( orders)

If you want to delete a specific order. Then you can do a hreadseek to find the order and run the script above to check wether it has orderlines.

HOnError() will help you but be very carefull with the error code .

if you using hyperfile or hyperfile server , the accuracy is 100%, but beware if you using external database .

I suggest you also show the full message in order to not get confuse.
