UPDATEは ????
、アップデータフィールドがアラビア語で書かれているかどうかを示し、これが私のクエリです。
UPDATE students
SET first_name = 'الاسم' , last_name = 'الاسم الاخير' ,
father_name = 'الاسم الاخير' , mother_name = '',
birth_date = '1/1/1990 12:00:00 AM' , education_level = '' ,
address = '' , notes = ''
WHERE student_id = 33
そして、これがアップデートの結果です:
student_id first_name last_name mother_name father_name birth_date
33 ????? ????? ?????? ??????????? 1990-01-01
//答えは素晴らしいです。ありがとうございます。別の質問は、C#プログラムでこのUPDATE構文を使用していることです。
