problem with concurrency - TIBCQuey

[jdure]

Good

Two users modify the same field in the table,
Error want to show the second user to save data.

-) Using a TClientDataser and TDatasetProvider, no problem, works well.

-) TFDQuery component FireDAC the Embarcadero it has the property
Property: UpdateOpcions
UpdateMode:
upWhereAll
upWhereChanged
upWhereKeyOnly

Implementing this property in TIBCQuery
solve my problem of concurrency.

thanks

Jdure,

What do you mean exactly by "concurrency" ?
If you get "deadlock", this error is thrown by Firebird server, and it really has nothing with IBCQuery, using it with or without upWhereChanged.
