2个表之间的差异

Question

我有两张桌子就是其中之一 AI: Ascent insensitive和其他AS: Ascent sensitive

我如何比较它们并区分它们？我使用了except

select  ID,FIRST,FATHER,GRAND  from t1

EXCEPT

select ID,FIRST,FATHER,GRAND  from t2

但我收到了这个错误：

  

无法解决＆＃34; Arabic_CI_AS＆＃34;之间的整理冲突和   ＆＃34; Arabic_100_CI_AI＆＃34;在EXCEPT操作中

Answer 1

选择一个合适的校对，以便字符串的比较符合要求（例如G.＆＃34; CI＆＃34; =区分大小写/不区分大小写），使用您的校对这样（忽略字符串的问题） ID中的EXCEPT列：

select  ID,
        FIRST  collate Arabic_CI_AS,
        FATHER collate Arabic_CI_AS,
        GRAND  collate Arabic_CI_AS
from t1

EXCEPT

select ID,
       FIRST  collate Arabic_CI_AS,
       FATHER collate Arabic_CI_AS,
       GRAND  collate Arabic_CI_AS
from t2

Answer 2

它在这里工作

USE [TestDb] GO

表1

CREATE TABLE [dbo].[t1](
    [ID] [int] IDENTITY(1,1) NOT NULL,
    [FIRST] [nchar](10) NULL,
    [FATHER] [nchar](10) NULL,
    [GRAND] [nchar](10) NULL,
 CONSTRAINT [PK_t1] PRIMARY KEY CLUSTERED 
(
    [ID] ASC
)WITH (PAD_INDEX = OFF, STATISTICS_NORECOMPUTE = OFF, IGNORE_DUP_KEY = OFF, ALLOW_ROW_LOCKS = ON, ALLOW_PAGE_LOCKS = ON) ON [PRIMARY]
) ON [PRIMARY]

GO

表2

CREATE TABLE [dbo].[t2](
    [ID] [int] IDENTITY(1,1) NOT NULL,
    [FIRST] [nchar](10) NULL,
    [FATHER] [nchar](10) NULL,
    [GRAND] [nchar](10) NULL,
 CONSTRAINT [PK_t2] PRIMARY KEY CLUSTERED 
(
    [ID] ASC
)WITH (PAD_INDEX = OFF, STATISTICS_NORECOMPUTE = OFF, IGNORE_DUP_KEY = OFF, ALLOW_ROW_LOCKS = ON, ALLOW_PAGE_LOCKS = ON) ON [PRIMARY]
) ON [PRIMARY]

GO
