MYSQL使用不同表的外键将数据插入表中

Question

我有一个由“LOAD DATA LOCAL INFILE”创建的临时表“teststepdump”。临时表包含表TestResult中通过外键连接在一起的不同表的数据:

1. teststepdump(虚拟编号、站号、名称、结果)
2. duttest(ID、DUTID、processTime)
3. dut(ID、DummyNr)
4. 车站(ID、车站编号)
5. teststepname(ID, 名称)
6. teststepresult(DUTTestID,TeststepID,结果)

我正在使用存储过程尝试这种方式，但收到错误 1452:

SQL Fehler (1452): Cannot add or update a child row: a foreign key constraint fails (database.teststepresult, CONSTRAINT teststepresult_ibfk_1 FOREIGN KEY (DUTTestID) REFERENCES 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

对于单个 INSERT，此存储过程对我有用，但我想避免“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
