MySQL error 1064 is a syntax error that occurs when the MySQL server encounters an error in the SQL syntax of a query. This error usually indicates that there is a problem with the SQL statement being executed, such as a missing or incorrect keyword, a missing or incorrect punctuation mark, or a missing or incorrect data type.
The error message for MySQL error 1064 typically includes the text "You have an error in your SQL syntax" followed by a description of the error and the specific query that caused the error.
Here are some examples of code that may trigger a MySQL error 1064, along with an explanation of why the error occurs:
- Missing keyword:
SELECT name, age FROM users;
This query will cause a MySQL error 1064 because the keyword "FROM" is missing, causing the MySQL server to not understand the query.
- Incorrect punctuation mark:
SELECT name, age FROM users;
This query will cause a MySQL error 1064 because the semicolon at the end of the query is missing, causing the MySQL server to not understand the query.
- Incorrect data type:
INSERT INTO users (name, age) VALUES ('John', 'twenty-five');
This query will cause a MySQL error 1064 because the data type of the "age" column is integer, but the value being inserted is a string.
In order to fix a MySQL error 1064, you need to examine the query that caused the error and identify the problem. Once you have identified the problem, you can make the necessary corrections to the query and re-execute it.
It is important to always check the syntax of your SQL queries before executing them, to ensure that they are correct and will not cause an error. You can use tools such as phpMyAdmin or MySQL Workbench to check the syntax of your queries and help you identify any errors.
In conclusion, MySQL error 1064 is a syntax error that occurs when the MySQL server encounters an error in the SQL syntax of a query. This error can be caused by missing or incorrect keywords, missing or incorrect punctuation marks, or missing or incorrect data types. To fix the error, you need to examine the query that caused the error and identify the problem, then make the necessary corrections to the query and re-execute it.
- Common causes of MySQL error 1064
- Not using the correct syntax for creating or altering a table, such as using a reserved word as a column name or not using the correct data type for a column.
- Using a single quote instead of a backtick to enclose a column or table name.
- Using a function or operator that is not supported by the version of MySQL you are using.
- Not using the correct syntax for a subquery or join.
- How to troubleshoot MySQL error 1064
- Check the error message for details about the specific query that caused the error and the location of the error within the query.
- Use tools such as phpMyAdmin or MySQL Workbench to check the syntax of your queries and help you identify any errors.
- Use the mysql command-line client and the source command to execute the query and see the exact error message, including line number and position of the error in the query.
- Test your query on a development server or a local installation of MySQL before deploying it to a live server.
- Best practices for avoiding MySQL error 1064
- Carefully read the MySQL documentation and reference manual to ensure that you are using the correct syntax for your queries.

- Keep your MySQL version up-to-date to ensure that you have access to the latest features and bug fixes.
- Use prepared statements instead of concatenating variables into your SQL queries to prevent SQL injection attacks.
- Tips for debugging MySQL errors in general
- Check the MySQL error log for more information about the error.
- Increase the value of the general_log and slow_query_log variables in the MySQL configuration file to log all queries and slow queries respectively.
- Use the EXPLAIN statement to analyze the query execution plan.
- Use the mysql command-line client and the source command to execute the query and see the exact error message.
- Try to reproduce the error in a test environment using sample data.
