SQL Server selects a row from a table using in an article

Question

I am having a strange problem with SQL Server.

Using the following query:

SELECT id FROM table WHERE id IN ('id1', 'id2', .......) 

when id is nchar (30) and 'id1', 'id2' are values, I get a result that is not in the entered values.

Is it possible that SQL Server is looking for the string contained in the values?

 CREATE TABLE [dbo].[WordDictionary]( [Word] [nchar](30) NOT NULL, [Count] [int] NOT NULL, CONSTRAINT [PK_WordDictionary] PRIMARY KEY CLUSTERED ( [Word] ASC )WITH (PAD_INDEX = OFF, STATISTICS_NORECOMPUTE = OFF, IGNORE_DUP_KEY = OFF, ALLOW_ROW_LOCKS = ON, ALLOW_PAGE_LOCKS = ON) ON [PRIMARY] ) ON [PRIMARY] 

Answer 1

The IN list contains the element '²' .

I will be very surprised if this is not the source of the problem (although this does not match me for my default setting)

Answer 2

Try making lines in the IN () Unicode clause, prefix N

 IN (N'Id1', N'Id2',...) 

Answer 3

AFAIK, SQL Server will respond as you and I expect. So I tried a small test case. and, of course, I got only the expected results.

If it is a text column, using LIKE / BETWEEN and other similar sentences can cause problems if you are not careful, but WHERE IN should be clear enough.

I suggest you post DDL + DML, which includes both “good” and unexpected results. Theoretically, you are doing the right thing, but until we see what you are working with, we will not be able to define "gotcha".

Answer 4

 select * from test where data IN ('Aa' COLLATE SQL_Latin1_General_CP1_CS_AS, 'Ab' COLLATE SQL_Latin1_General_CP1_CS_AS)
