ทำยังไง กับ Local Transaction ดีครับ ExecuteReader requires the command to have a transaction when the connection assigned to the command is in a pending local transaction. The Transaction property of the command has not been initialized
คือผมเจอ Error แบบนี้อะ

คือผมสามารถ execute ได้แค่ 4 transaction แรกอะ
เป็น transaction ที่ไม่มี local transaction
ส่วน 3 อันสุดท้าย ผมต้อง select ข้อมูลมาทำไรบางอย่าง
ก่อนจะ update ใน ฐานข้อมูลอะครับ
รบกวนผู้รู้ ช่วยไขปริศนาผมทีครับTag : - - - -

ผมไม่เข้าใจครับว่าทำไมจะต้องเปิด Transaction ขึ้นมาหลายตัวด้วยครับ ปกติแล้วการใช้ Conn.BeginTransaction(); จะใช้ครั้งเดียวครับ จากนั้นจะทำการ Insert/Update/Delete ข้อมูลกี่ Query ก็ได้ครับ
โดยที่สุดท้ายจะมีการ Commit หรือ RollBack ข้อมูลก็ขึ้นอยู่กับเงื่อนไขที่จะกระทำลงไปครับ ดูจากตัวอย่างนี้นนี้น่ะครับ
