The mysql create table command is [CREATE TABLE table_name (column_name column_type);], where the parameters include the table name, table field name, and each defined table field.
#How to create a MySQL data table? The following article will introduce to you how to create a data table through the command prompt. I hope it will be helpful to you.
The following information is required to create a MySQL data table:
● Table name
● Table field name
● Define each table field
Basic syntax
The following is the general SQL syntax for creating MySQL data tables:
CREATE TABLE table_name (column_name column_type);
Example: Create a table through the command prompt
MySQL data tables can be easily created through the mysql> command window. You can create a data table using the SQL statement CREATE TABLE.
1. First connect to the mysql server and enter the password
root@host# mysql -u root -p Enter password:*******
2. Enter the database RUNOOB
use RUNOOB;
3. Create the table
mysql> CREATE TABLE runoob_tbl( -> runoob_id INT NOT NULL AUTO_INCREMENT, -> runoob_title VARCHAR(100) NOT NULL, -> runoob_author VARCHAR(40) NOT NULL, -> submission_date DATE, -> PRIMARY KEY ( runoob_id ) -> )ENGINE=InnoDB DEFAULT CHARSET=utf8;
Output:
Query OK, 0 rows affected (0.16 sec)
indicates that the data table is created successfully.
Note: MySQL command terminator is semicolon;.
Note: -> is a newline identifier, do not copy it.
Example analysis:
●If you don’t want the field to be NULL, you can set the attribute of the field to NOT NULL. When operating the database, if the data entered in this field is NULL, an error will be reported.
● AUTO_INCREMENT is defined as a self-increasing attribute, generally used for primary keys, and the value will automatically increase by 1.
● The PRIMARY KEY keyword is used to define a column as the primary key. You can define a primary key using multiple columns, separated by commas.
● ENGINE sets the storage engine, CHARSET sets the encoding.

Explain the ACID properties (Atomicity, Consistency, Isolation, Durability).Apr 16, 2025 am 12:20 AMACID attributes include atomicity, consistency, isolation and durability, and are the cornerstone of database design. 1. Atomicity ensures that the transaction is either completely successful or completely failed. 2. Consistency ensures that the database remains consistent before and after a transaction. 3. Isolation ensures that transactions do not interfere with each other. 4. Persistence ensures that data is permanently saved after transaction submission.
MySQL: Database Management System vs. Programming LanguageApr 16, 2025 am 12:19 AMMySQL is not only a database management system (DBMS) but also closely related to programming languages. 1) As a DBMS, MySQL is used to store, organize and retrieve data, and optimizing indexes can improve query performance. 2) Combining SQL with programming languages, embedded in Python, using ORM tools such as SQLAlchemy can simplify operations. 3) Performance optimization includes indexing, querying, caching, library and table division and transaction management.
MySQL: Managing Data with SQL CommandsApr 16, 2025 am 12:19 AMMySQL uses SQL commands to manage data. 1. Basic commands include SELECT, INSERT, UPDATE and DELETE. 2. Advanced usage involves JOIN, subquery and aggregate functions. 3. Common errors include syntax, logic and performance issues. 4. Optimization tips include using indexes, avoiding SELECT* and using LIMIT.
MySQL's Purpose: Storing and Managing Data EffectivelyApr 16, 2025 am 12:16 AMMySQL is an efficient relational database management system suitable for storing and managing data. Its advantages include high-performance queries, flexible transaction processing and rich data types. In practical applications, MySQL is often used in e-commerce platforms, social networks and content management systems, but attention should be paid to performance optimization, data security and scalability.
SQL and MySQL: Understanding the RelationshipApr 16, 2025 am 12:14 AMThe relationship between SQL and MySQL is the relationship between standard languages and specific implementations. 1.SQL is a standard language used to manage and operate relational databases, allowing data addition, deletion, modification and query. 2.MySQL is a specific database management system that uses SQL as its operating language and provides efficient data storage and management.
Explain the role of InnoDB redo logs and undo logs.Apr 15, 2025 am 12:16 AMInnoDB uses redologs and undologs to ensure data consistency and reliability. 1.redologs record data page modification to ensure crash recovery and transaction persistence. 2.undologs records the original data value and supports transaction rollback and MVCC.
What are the key metrics to look for in an EXPLAIN output (type, key, rows, Extra)?Apr 15, 2025 am 12:15 AMKey metrics for EXPLAIN commands include type, key, rows, and Extra. 1) The type reflects the access type of the query. The higher the value, the higher the efficiency, such as const is better than ALL. 2) The key displays the index used, and NULL indicates no index. 3) rows estimates the number of scanned rows, affecting query performance. 4) Extra provides additional information, such as Usingfilesort prompts that it needs to be optimized.
What is the Using temporary status in EXPLAIN and how to avoid it?Apr 15, 2025 am 12:14 AMUsingtemporary indicates that the need to create temporary tables in MySQL queries, which are commonly found in ORDERBY using DISTINCT, GROUPBY, or non-indexed columns. You can avoid the occurrence of indexes and rewrite queries and improve query performance. Specifically, when Usingtemporary appears in EXPLAIN output, it means that MySQL needs to create temporary tables to handle queries. This usually occurs when: 1) deduplication or grouping when using DISTINCT or GROUPBY; 2) sort when ORDERBY contains non-index columns; 3) use complex subquery or join operations. Optimization methods include: 1) ORDERBY and GROUPB

mPDF
mPDF is a PHP library that can generate PDF files from UTF-8 encoded HTML. The original author, Ian Back, wrote mPDF to output PDF files "on the fly" from his website and handle different languages. It is slower than original scripts like HTML2FPDF and produces larger files when using Unicode fonts, but supports CSS styles etc. and has a lot of enhancements. Supports almost all languages, including RTL (Arabic and Hebrew) and CJK (Chinese, Japanese and Korean). Supports nested block-level elements (such as P, DIV),
