Question

Assume there is a table named ‘myTable’ with three columns:

{**ID**(PK, int, not null),   **X**(PK, int, not null),   **Name**(nvarchar(256), not null)}. 

Let {4, 1, аккаунт} be a record on the table.

select * from myTable as t      where t.ID=4       AND t.X = 1      AND (     t.Name = N'аккаунт'  )  select * from myTable as t      where t.ID=4       AND t.X = 1      AND (  t.Name LIKE N'%аккаунт%'  ) 

The first query return the record, however, the second does not? Why?

Systems where this issues are experienced:

*Windows XP – Professional – Version 2002 – SP3

Answer 1

Alright, after a great deal of research, I found it is indeed a problem found on the following versions of SQL Server 2005:

Windows XP – Professional – Version 2002 – SP3
Version: 9.00.3073.00
Level: SP2
Edition: Developer Edition

Version: 9.00.3054.00
Level: SP2
Edition: Enterprise Edition

..may be other versions as well.

FIX: Upgrade to SP3.
