Title: Bizarre way to get MySql AutoIncrement to work....
Post by: jorgemir on April 27, 2009, 08:03:15 PM

Hi. Some time ago I posted this question on the forum. At the time there where no solution and I went into other chores. Now, I'm working again on the subjet. A form won't let you insert a record with an autoincrement field. Problem is: Valid values can not be zero or blank, and you can not give it a value because it must go with zero value to the MySql database in order to get autoincremented. Gray hair until I casually discovered tha priming the field with -1 actually do works Ok. Record is entered with right next autoincrement value and everything is ok.
I don't know real mechanism of this behavior. Maybe next NTWS version won't budge, but right now, with PR35 is working.
Cheers.
Jorge

Hi Jorge,

Sounds like you've got the field set as "cannot be zero or blank" set in your dictionary. That would be where the NT validation comes from.

The -1 setting is a neat trick though, and one well worth knowing for MySql.
