Question

当我尝试在我的CUSTOMER_BILLING表格中插入新行时，我一直收到错误＆＃34;字符串或二进制数据会被截断。＆＃34; 外国密钥是CUST_ID，它来自CUSTOMER表

CUSTOMER表：

INSERT INTO CUSTOMER
VALUES ('1234','Ragnar','Lothbrok','457 Raiding Rd','Kattegat','PA','19335','4845555555', 'rlothbrok@gmail.com)
INSERT INTO CUSTOMER
VALUES ('1235','Daenerys','Stormborn','567 Targaryen Way','Westoros','CA','90001','3026781234','bendtheknee@gmail.com')
INSERT INTO CUSTOMER
VALUES ('1236','Jon','Snow','123 Winterfell Ave','Castle Black','CA', '90002','6109258787', 'winteriscoming@gmail.com')

CUSTOMER_BILLING table
INSERT INTO CUSTOMER_BILLING
VALUES ('123456',(SELECT CUST_ID FROM CUSTOMER WHERE CUST_ID='1234'),'15-May-2017','14-Jun-2017','01-Jun-2017','567890','457 Raiding Rd','Kattegat','PA','19335','4845555555','rlothbrok@gmail.com')

我不确定外键是否有问题。任何帮助都会很棒。我使用的是Microsoft SQL 2017。

Answer 1

试试这个：

INSERT INTO CUSTOMER
VALUES ('1234','Ragnar','Lothbrok','457 Raiding Rd','Kattegat','PA','19335','4845555555', 'rlothbrok@gmail.com')
INSERT INTO CUSTOMER
VALUES ('1235','Daenerys','Stormborn','567 Targaryen Way','Westoros','CA','90001','3026781234','bendtheknee@gmail.com')
INSERT INTO CUSTOMER
VALUES ('1236','Jon','Snow','123 Winterfell Ave','Castle Black','CA', '90002','6109258787', 'winteriscoming@gmail.com')

CUSTOMER_BILLING table
INSERT INTO CUSTOMER_BILLING
VALUES ('123456','1234','15-May-2017','14-Jun-2017','01-Jun-2017','567890','457 Raiding Rd','Kattegat','PA','19335','4845555555','rlothbrok@gmail.com')

Answer 2

问题可能来自于追加查询的SELECT子句中的嵌入式VALUES，特别是因为此子查询返回了多条记录。

考虑使用INSERT INTO ... SELECT追加查询，其中 CUST_ID 被检索，所有其他值都是标量。请注意，这将附加超过1条记录。如果不是这样，请使用DISTINCT。

此外，为了避免任何可能与数据类型冲突的列混淆，请考虑通过省略列明确声明INSERT INTO中的列而不是依赖列位置。

INSERT INTO CUSTOMER_BILLING (VarcharCol, VarcharCol, DateCol, DateCol, DateCol, 
                              VarcharCol, VarcharCol, VarcharCol, VarcharCol, 
                              VarcharCol, VarcharCol, VarcharCol)
SELECT '123456', CUST_ID, '15-May-2017', '14-Jun-2017', '01-Jun-2017', 
       '567890', '457 Raiding Rd', 'Kattegat', 'PA', '19335', 
       '4845555555', 'rlothbrok@gmail.com'
FROM CUSTOMER 
WHERE CUST_ID = '1234'
