MYSQL使用來自不同表的外鍵將數據插入表

Question

我有一個由「LOAD DATA LOCAL INFILE」創建的臨時表「teststepdump」。臨時表包含一起在表TestResult中由外鍵連接的不同的表的數據：

1. teststepdump（dummyno，stationno，名稱，結果）
2. duttest（ID，DUTID，processTime）
3. DUT （ID，DummyNr）
4. 站（ID，stationno）
5. teststepname（ID，姓名）
6. teststepresult（DUTTestID，TeststepID，結果）

我正嘗試使用存儲過程這種方式，但我得到錯誤1452：

SQL Fehler（1452）：不能添加或更新子行，外鍵約束 失敗（database。 teststepresult，約束 teststepresult_ibfk_1外鍵（DUTTestID）參考文獻duttest （ID）ON DELETE 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 

對於單個INSERT此存儲過程爲我工作，但我想，以避免「for」Loop;：

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

我解決了問題！

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
