MySQL is a widely used relational database management system that provides efficient, stable and secure data storage and management functions. However, when using MySQL, you may encounter various errors such as 1064 error.

The 1064 error is one of the most common errors in MySQL. It is usually caused by syntax errors or incorrect table structure definition. If you have been working with MySQL databases for a while, you may already be familiar with this error. However, if you are new to MySQL, you need to know some basic knowledge and solutions about 1064 errors.

First of all, we need to understand the cause of the 1064 error. Common grammatical errors include using misspellings and missing parentheses, quotation marks, etc. For example, the following SQL statement is problematic:

INSERT INTO user(id, name, age)VALUES(1, 'Tom', 20);

If you copy the above SQL statement to the MySQL command line and execute it, you will get a 1064 error. This is because MySQL does not allow omitting parentheses in a VALUES clause. The correct SQL statement should be:

INSERT INTO user(id, name, age)VALUES(1, 'Tom', 20);

In addition, the 1064 error may also be caused by incorrect definition when creating the table. For example, the following SQL statement will generate a 1064 error when creating a table:

CREATE TABLE userinfo(
  id INT UNSIGNED NOT NULL AUTO_INCREMENT,
  name VARCHAR(20) NOT NULL,
  email VARCHAR(30),
  reg_date TIMESTAMP
  created_at DAYTIME,
  PRIMARY KEY (id)
);

What is the problem? Quite simply, we are missing a comma on the "created_at" column, which causes a syntax error. In order to create the table structure correctly, we need to change the SQL statement to:

CREATE TABLE userinfo(
  id INT UNSIGNED NOT NULL AUTO_INCREMENT,
  name VARCHAR(20) NOT NULL,
  email VARCHAR(30),
  reg_date TIMESTAMP,
  created_at DAYTIME,
  PRIMARY KEY (id)
);

Next, we need to know how to solve the 1064 error. First of all, when you encounter such an error, you should carefully check the error message to find out the specific cause of the error. Error prompts are usually displayed in the MySQL command line, for example:

ERROR 1064 (42000): You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax

In this error prompt, we can see that the reason why the error occurs is due to incorrect syntax, so we need to check the syntax of the SQL statement.

Secondly, you can use some tools provided by MySQL to solve the 1064 error. For example, MySQL Workbench is a powerful database design and management tool that can help you create and modify table structures, and detect and resolve syntax errors. In addition, MySQL also provides some command line tools and code libraries that can help you solve 1064 errors more easily.

Finally, the best way to avoid 1064 errors is to maintain good coding habits. When writing SQL statements, you should try to avoid grammatical errors such as misspellings or missing parentheses. In addition, always using standard SQL syntax and good table structure definition can help you avoid 1064 errors.

In short, the 1064 error is one of the most common errors in MySQL, but you can avoid such problems by understanding its causes and solutions. When writing SQL statements, you should avoid syntax errors as much as possible and follow standard SQL syntax and good table structure definitions. If you still encounter a 1064 error, please double-check and find the error, or use the tools provided by MySQL to solve the problem.
