这些是我的表:
tbl_student (studID,Firstname)
我研究过的是骄傲的
finger_template(Detail_ID,FingerprintMask)
我想删除
tbl_student
和finger_template
中的记录。这是我的查询:command = New MySqlCommand("DELETE from tbl_student where studid='" & priid & "'", connection, transaction)
希望有人能帮忙
最佳答案
表格:tbl_student
+-------------+-----------+
| studID (PK) | Firstname |
+-------------+-----------+
| **000001** | John |
+-------------+-----------+
表:finger_template
+----------------+-----------------+-------------+
| Detail_ID (PK) | FingerprintMask | studID (FK) |
+----------------+-----------------+-------------+
| 000001 | SampleMask | **000001** |
+----------------+-----------------+-------------+
如果tbl_student
studID
PK链接到finger_template stuID
FK您只需删除
studID
PK,FK也将被删除DELETE FROM tbl_student WHERE studID=000001
