How to solve mysql 1064 error

MySQL1064 error is one of the common errors in MySQL database, mainly caused by syntax errors in SQL statements. In MySQL, SQL statements are the core language used to query and operate the database. If there are errors in the SQL statements, a 1064 error will be thrown.

In this article, we will introduce the causes and solutions of the MySQL 1064 error, and help readers understand how to prevent and repair this error in MySQL.

1. Causes of MySQL 1064 error

1. SQL syntax error: Syntax error is the most common error in SQL statements. This error is usually caused by spelling in the written SQL statement. Errors, missing parentheses, missing commas, etc.

For example:

 SELECT FROM users WHERE user_id=1;

The error is that the SELECT statement is missing the field to be queried. It should be changed to:

 SELECT username FROM users WHERE user_id=1;

2. The database engine does not support some Characters: The character set and collation rules in MySQL are processed by the database engine. If the SQL statement you enter uses characters that it does not support, a 1064 error will occur.

For example:

 CREATE TABLE t1 (id INT PRIMARY KEY, name VARCHAR(60)) ENGINE=MyISAM DEFAULT CHARSET=utf8;

3. Duplicate names: In MySQL, names (such as table names, column names) must be unique. If you set a name that already exists, a 1064 error will occur.

For example:

 CREATE TABLE t1 (id INT PRIMARY KEY, name VARCHAR(60), id INT);

The id column is defined twice and should be changed to:

 CREATE TABLE t1 (id INT PRIMARY KEY, name VARCHAR(60), age INT);

2. Solve the MySQL 1064 error

1. Check the SQL statement: Check whether there are spelling errors, missing commas, quotation marks, brackets and other errors in the SQL statement.
2. Check the database engine and character set: If the SQL statement you entered uses certain characters that are not supported by the database engine, you can solve the problem by modifying the character set.
3. Check for duplicate names: Check whether table names, column names and other names are duplicated. You can solve this problem by modifying the names.
4. Use MySQL client: Using MySQL client can help you create and execute SQL statements more easily, and can automatically check for syntax errors.
