单个SQL查询删除两个表中的记录

Question

这些是我的表格：

tbl_student (studID,Firstname) 

我的专注是 priid

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)

希望有人会帮助

Answer 1

表：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 你只需删除studID PK，FK也会被删除DELETE FROM tbl_student WHERE studID=000001
