Datensatz Sperre MySQL

[KlausV]

Ich verstehe nur nicht, wieso sich Delphi oder mysql so verhält. Vor einem Monat konnten wir noch ganz normal die Daten ändern.
Hat jemand noch einen Tipp bezüglich mysql? Irgendwo muss sich ja etwas verändert haben. Den gleichen Satz, den ich mit dem Delphi Programm nicht ändern kann, kann ich unter SQL update direkt ändern.
Einen SHOW OPEN TABLES zeigt mir keine Sperren, ebenso kann ich nichts verdächtiges feststellen, wenn ich show engine innodb status starte.
Falls es sich nicht löst, dann werde ich den Mode auf upWhereKeyOnly ändern.
Ich befürchte halt nur, dass es nach und nach auch andere Tabellen betrifft.
Hier der Auszug aus show engine...


mysql> show engine innodb status;
