, crash- repair , and Multi-version concurrency control transaction security. In MySQL starting from 3.23.34a contains Innnodb. It is the first table engine on MySQL to provide a foreign key constraint. and InnoDB's ability to handle transactions is unmatched by other storage engines. The later version of MySQL's default storage engine is InnoDB support ID self-increment , also support foreign key The

TypeSimplify:string number, bool AutoHotkey does not explicitly define variable types; All variables are stored as strings. However, when a variable that contains only numbers ( and can have decimal points ) is mathematically calculated or compared, it is automatically converted to a numeric value ( Integer or floating-point number, etc. ). Conversely, when the result of a mathematical operation needs to be stored in a variable, it is converted back

code block are then taken with a intenral link property. But this does not mean that he can only be given the property of the code block that is intenral by the link property.The real reason is that the local variable is treated as a variable of type auto.Register: Variables stored in registers, what are the characteristics of registers we all know that the efficiency of the register is often used for repetitive variable operations. AttentionYou cannot use global variables to apply, typically a

The range and storage size of various int types in MySQL, mysqlint The integer type int in MySQL mainly includes the following types: The tinyint range is-128 ~ 127; The int value ranges from-2 ^ 31 (-2,147,483,648) to 2 ^ 31-1 (2,147,483,647). The storage size is 4 bytes; Bigint ranges from-2 ^ 63 (-922337203685

The attributes of variables and functions include the data type and data storage class. The storage class index data is stored in memory (static and dynamic), including auto, static, register, and extern. Memory. Specifically, memory is divided into three parts: static zone, heap zone, and stack zone. External variables and global variables are stored in the static zone, local variables are stored in the s

The C language describes variables in two aspects: variable types and Storage types of variables. Variable types such as int (integer) and char (character type) indicate the memory space occupied by the variable. The variable storage type is used to describe the scope of the

Tags: mysql int integer typeThe integer type int in MySQL is mainly as follows: The range of tinyint is -128~127; int ranges from -2^31 (-2,147,483,648) to 2^31–1 (2,147,483,647) for integer data (all numbers), with a storage size of 4 bytes; The bigint range is the integer data (all numbers) of -2^63 (-9223372036854775808) to 2^63-1 (9223372036854775807). The storage size is 8 bytes; The range of smallint

The storage type of a variable determines when the scalar is created, when it is destroyed, and how long his value remains. There are three places where variables can be stored:Normal memory staticRun-time Stack autoHardware Register RegisterThe default storage type of a variable depends on where it is declared: static variablestatics: variables declared outside the code block are always stored in

modified. So this is a change that can be maintained. At last:In a sense, objects are made up of basic types. You can look at an object as a tree, the object's properties, if it is an object, is still a tree (that is, a non-leaf node), and the base type is the leaf node of the tree. When a program parameter is passed, the passed value itself cannot be modified, but if the value is a non-leaf node (that is, an object referen

add static to the external property by default, you can make his property internal.For example, the above static int b; and the static int C (int d) becomes the source file private and cannot be accessed by other files.Static only works on declarations with the default property of external, which is completely different from the effect of none by default.extern OK. The identifier of the None property becomes the external property.For example, the above extern int e can be modified to use the e
