MySQL is one of the most popular relational database management systems currently. Its speed and reliability make it a popular choice. However, when using MySQL, you sometimes encounter a very common error: Error 1064. This error usually points to a SQL syntax error, and it can be difficult to know exactly why it is. In this article, we will take a deep dive into MySQL error 1064, explain why it happens and how to fix it.

Common causes of error 1064

In MySQL, error 1064 is usually caused by the following situations.

1. Missing or misspelled keywords

MySQL performs operations on data through keywords, and missing or misspelled keywords are usually one of the main causes of error 1064.

For example, the following SQL query is missing a keyword:

SELECT name, FROM users WHERE id=1;
Copy after login

In this query, the field between the "SELECT" keyword and the comma is missing, and MySQL cannot parse it. This query returns a 1064 error.

2. Missing semicolon at the end

The MySQL statement must end with a semicolon, otherwise MySQL cannot parse the statement correctly. Therefore, if the SQL statement does not end with a semicolon, error 1064 will be raised.

For example:

SELECT * FROM users WHERE id=1
Copy after login

In this query, the trailing semicolon is missing, so MySQL throws error 1064.

3. Unclosed quotation marks

In MySQL queries, strings must be placed in quotation marks, and quotation marks must always appear in pairs. If you forget to close the quotes, MySQL will not be able to parse your query properly and will throw error 1064.

For example:

SELECT * FROM users WHERE name='Alice;
Copy after login

In this query, you forgot to close the single quotes, so MySQL throws error 1064.

4. Use of illegal characters

Some characters in the MySQL query may be interpreted as syntax errors, triggering error 1064. For example, use the colon ":" symbol in the query.

For example:

SELECT * FROM users WHERE date_created > '2021-01-01 00:00:00';
Copy after login

In this query, the date format contains the colon symbol ":", so MySQL throws error 1064.

5. Use too many spaces

In MySQL queries, spaces are usually used to separate different query elements. However, if you use spaces where they shouldn't be used, such as table or column names in a query, they will be interpreted as a syntax error and error 1064 will occur.

For example:

SELECT name,address FROM users where id = 1;
Copy after login

In this query, there is an extra space between the words "users where" in the query, so MySQL throws error 1064.

How to solve MySQL error 1064

The following are several ways to solve MySQL error 1064:

1. Check the syntax carefully

When you encounter an error 1064, you should first carefully check the syntax of the SQL statement. Eliminate grammatical errors such as misspellings, missing keywords, or use of invalid characters.

2. View the MySQL documentation

Viewing the MySQL documentation can help you understand common errors and solutions when using MySQL. You can check the MySQL manual for a more in-depth understanding of specific syntax errors.

3. Use the MySQL command line

Using the MySQL command line, you can more easily determine which SQL statements have syntax errors, because MySQL will point out the location of the syntax errors. When entering SQL statements at the MySQL command line, you can also use shortcut methods (such as the TAB key) to automatically complete SQL statements or column names.

4. Use MySQL tools

Using MySQL tools can help you manage MySQL databases more easily. Many modern tools, such as phpMyAdmin and MySQL Workbench, provide visual user interfaces that make it easier to create and manage MySQL queries and databases.

5. Ask for help

If MySQL error 1064 occurs and cannot be resolved, you can use the MySQL forum or Q&A website to post questions. Other MySQL users and experts can help you troubleshoot errors.

Conclusion

Error 1064 is one of the most common errors in MySQL, but it can be solved by checking the SQL statement, viewing the MySQL documentation, using the command line or MySQL tools. If you encounter error 1064 and can't resolve it, don't be afraid to ask for help. By understanding the causes of errors, you can avoid them more easily and resolve them faster.
