A brief analysis of the causes and solutions of MySQL error 1064

MySQL is a widely used relational database management system. However, it is inevitable to encounter errors when using MySQL. Among them, error 1064 is one of the most common errors in MySQL. This article will introduce you to the causes and solutions of MySQL error 1064.

1. Cause

Error 1064 is a MySQL syntax error. It is usually caused by syntax errors when executing SQL commands. Common mistakes include incorrect use of quotation marks, semicolons, or parentheses.

2. Solution

To resolve error 1064, you can take the following steps:

Step 1: Check the SQL statement

Please check whether your SQL statement is correct. Please check that the quotes, semicolons, and parentheses in the statement match correctly.

Step 2: Check the table name and column name

Please make sure your table name and column name are correct. They should exist in the database. If there are spaces between your table names and column names, add backticks. If you use an alias in your SQL statement, make sure the alias is correct.

Step 3: Check the data type

Please make sure the value type you enter is correct. For example, if your data type is an integer, you should not enter a string value.

Step 4: Check for special characters

Please make sure there are no special characters in your SQL statement. For example, you should not use special characters such as "!" and "@" in SQL statements. If you must use these characters, use escape characters.

Step 5: View the MySQL error log

You can view the MySQL error log for more information. The location of the error log files varies by operating system. In Linux systems such as Ubuntu, error log files are usually located in /var/log/mysql/. In Windows systems, error log files are usually located in the data folder under the MySQL installation directory.

Step 6: Use the MySQL command line tool to troubleshoot

In the MySQL command line tool, you can try to enter an incorrect SQL statement to obtain an error message. For example, entering "mysql> SELECT * FROM employees WHERE id="1" AND name="John";" into the MySQL command line tool will result in error 1064. MySQL will tell you details about the error.

With the above steps, you can resolve MySQL error 1064. However, be sure to follow standard syntax when writing SQL statements to avoid common mistakes. If you don't know how to construct a correct SQL statement, please refer to the MySQL official documentation or ask a professional.

To resolve this error, you need to check quotes, semicolons, and parentheses in the SQL statement, check table and column names, data types, and special characters.
