لماذا تظهر هذه الرسالة لي دائما

السلام عليكم

عند عمل update query أو append query

دائما عند تنفيذ الاستعلام تظهر هذه الرسالة

Microsoft access can't append all the records in the append query

Microsoft access set 0 field(s) to null due to atype conversion failure , and it didn't add 800 records to the table due to key violations, 0 records due to lock violation , and 0 record due to violation rule violation .
do you want to run the action query any way?
To ignore the errors and run the query , click yes.
