Label:For example, Microsoft SQL Server 2008 supports four table operator-join,apply,pivot,unpivot in SQL2008. The Join table operator is an ANSI standard, while the other three types are T-SQL extensions to the standard. Today is primarily about working with join tables. The join table operator operates on two input tables. There are three basic types of joins: Cross joins, Inner joins and outer junctions. The difference between the three types of jo

1. How to obtain the number of characters in a string that contains both single-byte and double-byte characters?
You can call the Runtime Library of Microsoft Visual C ++ to contain the function _ mbslen to operate multi-byte strings (including single-byte and dual-byte strings.Calling the strlen function does not really know how many characters are in the string. It only tells you how many bytes are before the end of 0.

The support for wide characters is actually part of the ansi c standard, used to support multi-byte expression of a character.
The width character is not exactly the same as the Unicode character. Unicode is only a type of width character encoding.

In ANSI, the length of a character (char) is one byte ). When Unicode is used, a charact
