MYSQL使用来自不同表的外键将数据插入表中

Question

我有一个临时表“teststepdump”由“LOAD DATA LOCAL INFILE”创建。临时表包含表TestResult：

中由外键连接的不同表的数据

1. teststepdump（dummyno，stationno，name，result）
2. duttest（ID，DUTID，processTime）
3. dut（ID，DummyNr）
4. 站（ID，stationno）
5. teststepname（ID，name）
6. teststepresult（DUTTestID，TeststepID，结果）

我正在尝试使用存储过程，但我收到错误1452：

  

SQL Fehler（1452）：无法添加或更新子行：外键   约束失败（database。teststepresult，CONSTRAINT   teststepresult_ibfk_1外键（DUTTestID）参考duttest   （ID）ON UPETE CASCADE ON UPDATE CASCADE）

BEGIN
DECLARE dt_id INT;
SELECT teststepresult.DUTTestID INTO dt_id FROM teststepresult
INNER JOIN duttest ON teststepresult.DUTTestID = duttest.ID
INNER JOIN dut ON duttest.DUTID = dut.ID
INNER JOIN station ON duttest.StationID = station.Nummer
INNER JOIN teststepdump ON teststepresult.ID = teststepdump.ID
WHERE
dut.DummyNr = teststepdump.dummyno AND
station.Nummer = teststepdump.stationno;

INSERT INTO teststepresult (DUTTestID, TeststepID, Result) 
SELECT dt_id, teststepname.ID, teststepdump.Result 
FROM teststepdump
INNER JOIN teststepname ON teststepdump.name = teststepname.name
WHERE 
teststepname.name = teststepdump.name;
terminate teststepdump;
END

对于单个INSERT，这个存储过程对我有效，但我想避免使用“for”循环;：

BEGIN

DECLARE t_id INT;
DECLARE tn_id INT;

SELECT teststepname.ID INTO tn_id FROM teststepname 
WHERE  teststepname.Name = name;

SELECT duttest.ID INTO t_id FROM duttest
INNER JOIN dut ON duttest.DUTID = dut.ID 
INNER JOIN station ON duttest.stationID = station.ID
WHERE
dut.DummyNr = dummyno AND 
station.Nummer = stationno;

IF NOT t_id IS NULL AND NOT tn_id IS NULL THEN
INSERT INTO teststepresult (DUTTestID, TeststepID, Result) 
VALUES (t_id, tn_id, Result);
END IF;
END

我解决了问题！

BEGIN
INSERT INTO teststepresult (DUTTestID, StepName, Result) 
SELECT duttest.DUTID, teststepdump.name, teststepdump.Result 
FROM duttest
INNER JOIN dut ON duttest.DUTID = dut.ID
INNER JOIN station ON duttest.StationID = station.ID
INNER JOIN teststepdump ON dut.DummyNr = teststepdump.dummyno
WHERE 
dut.DummyNr = teststepdump.dummyno AND
station.Nummer = teststepdump.stationno;
#truncate teststepdump; 
END
