The SQL Server Database Engine follows the ANSI/ISO SQL-92 specification (Section 8.2,Comparison Predicate, General rules #3) on how to compare strings with spaces. The ANSI standard requires padding for the character strings used in comparisons so that their lengths m...
但是SQL Server在查询的时候比较空字符串时,长度为零的空字符串与长度为1的字符串,长度为N的字符串,它们似乎是等价的。跟Oracle的行为完全不一样。这个的解释如下,详情参考官方文档[2]: SQL Server follows the ANSI/ISO SQL-92 specification (Section 8.2,, General rules #3) on how to compare strings wi...

This section uses tables to compare the syntax and description of Data Manipulation Language (DML) elements in the Microsoft SQL Server and Oracle databases. Each table is followed by a recommendations section based on the information in the tables. The following topics are presented in this sectio...
Integration Services and SQL Server differ in the way they compare strings. If the Lookup transformation is configured to load the reference dataset into cache before the Lookup transformation runs, Integration Services does the lookup comparison in the cache. Otherwise, the lookup operation uses a ...

This occurs because of the difference in the way DQS compares strings in the SQL Server database and C#. The string comparison in the SQL Server database is case insensitive whereas it is case sensitive in C#. Let us illustrate this with an example. Consider a user, Domain\user1. The us...

The advantage of using a Binary-code point sort order is that no data resorting is required in applications that compare sorted SQL Server data. As a result, a Binary-code point sort order provides simpler application development and possible performance increases. For more information, see the ...
