我该怎么办1单击执行此T-SQL

Question

我正在使用SQL 2012，我希望所有代码都能同时工作。但是给我这个错误。 我应该如何走。 谢谢。

BEGIN

USE [DLSaglikNet]

CREATE TABLE PASSAPORT_TURU
(
ID int NOT NULL PRIMARY KEY IDENTITY (1,1),
ADI varchar(70) ,
KODU varchar(20)
)

INSERT INTO PASSAPORT_TURU (ADI,KODU)
VALUES 
('Passaport Numarası','1'),
('Yabancı Hasta T.C. Kimliği','2'),
('Lütfen Seçim Yapınız.','3')

Alter table HASTA Add PASSAPORTTURU int CONSTRAINT FK_HASTA_PASSAPORT_TURU foreign key (PASSAPORTTURU) REFERENCES PASSAPORT_TURU(ID)

Update HASTA set PASSAPORTTURU = 1 where PASSAPORT IS NOT NULL and TCKIMLIK IS NULL and PASSAPORTTURU IS NULL

Update HASTA set PASSAPORTTURU = 3 where PASSAPORT IS NULL and TCKIMLIK IS NOT NULL

END;

GO

Answer 1

在执行DDL语句时，需要在其后使用GO关键字，这意味着将执行批处理和脚本。

  

这些命令可用于简化批处理和脚本的可读性和执行。

确保

Alter table HASTA Add PASSAPORTTURU int CONSTRAINT FK_HASTA_PASSAPORT_TURU foreign key (PASSAPORTTURU) REFERENCES PASSAPORT_TURU(ID)

在插入数据之前执行。

BEGIN

USE [DLSaglikNet]

CREATE TABLE PASSAPORT_TURU ( ID int NOT NULL PRIMARY KEY IDENTITY (1,1), ADI varchar(70) , KODU varchar(20) )

INSERT INTO PASSAPORT_TURU (ADI,KODU) VALUES ('Passaport Numarası','1'), ('Yabancı Hasta T.C. Kimliği','2'), ('Lütfen Seçim Yapınız.','3')

Alter table HASTA Add PASSAPORTTURU int CONSTRAINT FK_HASTA_PASSAPORT_TURU foreign key (PASSAPORTTURU) REFERENCES PASSAPORT_TURU(ID)

GO -- <-- ADD GO HERE.

Update HASTA set PASSAPORTTURU = 1 where PASSAPORT IS NOT NULL and TCKIMLIK IS NULL and PASSAPORTTURU IS NULL

Update HASTA set PASSAPORTTURU = 3 where PASSAPORT IS NULL and TCKIMLIK IS NOT NULL

END;.

Answer 2

您需要先检查您的alter是否存在，然后添加到代码末尾：

if not exist(select PASSAPORTTURU from HASTA )
    Alter table HASTA Add PASSAPORTTURU int CONSTRAINT FK_HASTA_PASSAPORT_TURU foreign key (PASSAPORTTURU) REFERENCES PASSAPORT_TURU(ID)
go --here adding go
Update HASTA set PASSAPORTTURU = 1 where PASSAPORT IS NOT NULL and TCKIMLIK IS NULL and PASSAPORTTURU IS NULL
go
Update HASTA set PASSAPORTTURU = 3 where PASSAPORT IS NULL and TCKIMLIK IS NOT NULL

Answer 3

在更新语句行上方使用Go关键字。

Go
Update statements

这将确保alter语句在尝试更新表之前已经发生。
