What does this paragraph SQL mean, what does SQL mean

1. Select the value with the largest user id in the users table and pay the variable @user id;

2. Store the value of the variable @user id to the field (userbase userid) in the userbase database table and the userstate userid field in the userstate database table.

3. Execute the stored procedure up change userbase, which is a program that ranks users**. Select the user ID with the largest number of points and list its information.

select @user id = max ([user id]) from users -- assigns the user id you just inserted to the variable @user id

Assign the largest user id in the users table to the variable @user id

*insert into userbase (userbase_userid)values(@user_id)

*insert into userstate (userstate_userid)values(@user_id)

Insert the @user ID into the userbase and userstate tables respectively.

*exec up change userbase -- execute another stored procedure up change userbase

Another: Your sentence is followed by an explanation:

Double bars - the following is the explanation of each sentence.

In order: 1, find the value of the user id with the largest value in the users table and pay the variable @user id;

2, The following two actually mean the same thing, pay the value of the variable @user id to the userbase column (userbase userid), and the userstate column userstate userid;

3. Execute the stored procedure up change userbase, I don't know if you understand it.

Insert a record into the users table.

select @user id = max ([user id]) from users -- assigns the user id you just inserted to the variable @user id

*insert into userbase (userbase_userid)values(@user_id)

*insert into userstate (userstate_userid)values(@user_id)

Insert the @user ID into the userbase and userstate tables respectively.

*exec up change userbase -- execute another stored procedure up change userbase

Summary. SQL is an abbreviation for Structured Query Language, a standardized language for managing relational databases. SQL can query, insert, update, and delete databases, and also supports data definition, transaction control, and user rights management.

SQL is an abbreviation for Structured Query Language, a standardized language for managing relational databases. SQL can query, insert, update, and delete the auction database, and also supports functions such as data definition, transaction control, and user rights management.

SQL was originally developed by IBM's Father-in-Cheek Division, and later became a code for ISO and ANSI standards. At present, SQL has become one of the most commonly used languages in relational database management systems (RDBMS), including MySQL, Oracle, Microsoft SQL Server and other mainstream databases support SQL operations.

In SQL, keywords such as select, insert, update, and delete are commonly used to perform different operations. For example, Crack Liang can use the select statement to check the rough query data from the key database; The insert statement allows you to insert new data into the database. You can use the update and delete statements to modify or delete existing data.

Summary. SQL (Structured Query Language) is a database language with a variety of functions such as data manipulation and data definition, this language has interactive characteristics, can provide users with great convenience, database management system should make full use of SQL language to improve the quality and efficiency of computer application system. The SQL language can not only be used independently in the terminal, but also can be used as a sub-language to provide effective assistance for other program design, in which SQL can be used with other programming languages to optimize the program functions and provide users with more and more comprehensive information.

1] SQL Server database includes two sub-databases, Microsoft SQL Server and Sybase SQL Server, and whether the database can run normally is directly related to the operation security of the entire computer system.

Hello SPL stands for Structured Query Language, which translates to Structured Query Language. It is a standardized language for database management systems that can be used to create, delete, and modify database tables and contents. SQL is one of the core technologies of relational database management systems, which allows users to query and manage data through simple and easy-to-understand syntax.

Hello dear <> spl stands for Structured Query Language, which translates to Structured Query Language. It is a standardized language for data database management and infiltration systems, which can be used to create, delete, and modify database tables and contents. SQL allows users to query and manage data through a simple and easy-to-understand syntax, which is one of the core technologies of relational database management systems.

Addendum: The SQL language was developed by IBM in the early 70s of the 20th century, and now it has become an international standard. SQL can be divided into three types: Data Definition Language (DDL), Data Manipulation Language (DML), and Data Control Language (DCL).

DDL is mainly used to create and modify database objects, such as tables and views. DML is mainly used to add, delete, modify, and query data in a table<>

Summary. Common SQL commands include SELECT (query data), insert (insert data), update (update data), delete (delete data), create (create new tables, indexes, or other database objects), and drop (delete tables, indexes, or other database objects). SQL is not only one of the essential skills for database developers, but also widely used in data analysis, data mining, business intelligence, and other fields.

In practice, there may be some differences between database vendors, but SQL standards are still the common core of all databases. <>
