First Reader Network reference The code is as follows Copy Code CONVERT (expr USING transcoding_name) In MySQL, transcoding names are the same as the corresponding character set names. Examples: The code is as follows Copy Code SELECT CONVERT (_latin1 ' Müller ' USING UTF8);INSERT into utf8table (utf8column) SELECT CONVERT (Latin1field USING UTF8) from latin1table; CONVERT (.....) USING ...) is implemented according t

In SQL Server, both the cast and CONVERT functions are available for type conversions, and their functions are the same.It's just a different syntax.Cast is generally easier to use, and the advantage of convert is that dates and values can be formatted.1 Select CAST('123' as int)--1232 Select CONVERT(int,'123')--1233 4 Select CAST(123.4 as int)--1235 Select CON

The first thing to say is that you use the malloc function to include stdlib.h (Cstdlib in C + +), not malloc.h. Because Malloc.h never appeared in C or C + + standards! So not all compilers have malloc.h this header file. But all C compilers should have stdlib.h this header file. In C + +, the return value of the cast malloc () is required, otherwise it cannot be compiled. In C, however, this cast is redu

This article quoted: http://www.jb51.net/article/41333.htmOperator is used for type conversion functions:Characteristics of a type conversion function:1) Type conversion function is defined in the source class;2) must be modified by operator, the function name is the target type name or the target class name;3) The function has no parameters, there is no return value, but there is a return statement, the target type data is returned in the return statement, or the constructor of the target class

Va 657-The die is cast (dual BFS) InterGames is a high-tech startup company that specializes in developing technology that allows users to play games over the Internet. A market analysis has alerted them to the fact that games of chance are pretty popular among their potential MERs. be it Monopoly, ludo or backgammon, most of these games involve throwing dice at some stage of the game. Of course, it wocould be unreasonable if players were allowed

From JavaWorld, see the original article:When catching exceptions, dont cast your net too wideBy Dave SchweisguthUnderstand how the Java compiler checks catch clauses during compilation.SummaryCompared with other languages, Java's simplicity and consistency enable the compiler to detect many errors. Java developers realize how to rely on the compiler to capture incorrect types, nonexistent methods (the topic of this Article), and incorrect exception h

specific implementation of the compiler has a difference, VC6 take the non-compression method, dev-c++ take compression;4) If the bit field fields are interspersed with non-bit field fields, no compression is performed;5) The total size of the entire struct is an integer multiple of the size of the widest base type member.Let's take a look at the example.Example 1:struct BF1{Char F1:3;Char F2:4;Char F3:5;};Its memory layout is:|_f1__|__f2__|_|____f3___|____||_|_|_|_|_|_|_|_|_|_|_|_|_|_|_|_|0 3

Now I will introduce the CAST and CONVERT used in this article in detail:Let's take a look at their syntax:CAST (expression AS data_type [(length)])CONVERT (data_type [(length)], expression [, style])Where:Expression: Any valid expression.Data_type: Target data ty
