How to Fix MySQL Error 1064? Know its Reasons and Solutions

What is MySQL Error 1064 and How to Fix it?

Error 1064 in the context of MySQL is a syntax error, indicating an issue with the SQL query you’ve executed. This type of error suggests that MySQL does not understand the statement due to incorrect syntax, which can include:

• Invalid SQL Statement: Typos or incorrect commands.
• Missing or Extra Punctuation: Such as missing commas, parentheses, or quotation marks.
• Improper Use of Reserved Words: Using keywords without proper escaping.
• Incorrect Data Types: Mismatches between expected and provided data types. 

How to Fix MySQL Syntax Error?

There are many of the solutions available to solve the MySQL error 1064. First, we discuss the manual methods then we discuss the automated solution to solve this issue with ease.

Manual Method to Fix MySQL Error 1064

To manually fix SQL Error 1064, follow these steps:

1. Review the SQL Query: Review the error message carefully. It typically includes the line number and a snippet of the SQL query that caused the issue. This helps pinpoint where to focus your attention.
2. Check Syntax Structure: Ensure the query follows the correct syntax for SQL commands (e.g., SELECT, INSERT, UPDATE). Confirm that the query follows the correct format. For instance:
   • SELECT: `SELECT column1, column2 FROM table WHERE condition;`
   • INSERT: `INSERT INTO table (column1, column2) VALUES (value1, value2);`
3. Verify Punctuation: Look for missing or misplaced commas, parentheses, or quotation marks. Ensure all necessary SQL keywords are present and in the right order.
   • Example: Make sure each column name is separated by a comma in SELECT statements. Strings should be enclosed in single quotes, while identifiers may require backticks.
4. Escape Reserved Words: If you use reserved keywords as table or column names, enclose them in backticks (“ ` “). In MySQL, receiving an error message with the code 1064 may indicate that you have used words that MySQL considers special, known as “reserved words.” Examples include ALTER, TABLE, SELECT, and others. Reserved words have specific meanings in MySQL, and using them as names for tables, columns, or other database elements can lead to errors. For instance, using the reserved word “ALTER” as a table name can cause an SQL syntax error.
5. Examine Data Types: Ensure that the values you are inserting or comparing match the expected data types defined in your database schema. Strings should be in quotes, while numbers should not.
6. Simplify the Query: Break down complex queries into smaller parts to isolate the error. Execute each part separately. Start with a basic version of your query and gradually add complexity. This can help isolate the section of the query that is causing the error.
   • For example, if you have a complex JOIN statement, try executing just one of the SELECT statements first.
7. Consult Documentation: Reference MySQL documentation for the correct syntax of the specific command you’re using.
8. Test Incrementally: Gradually add elements back to a simplified version of the query to see which addition causes the error.
9. Use a SQL Formatter: Utilize online SQL formatting tools to help identify issues in your query structure.

By following these steps, you can systematically identify and resolve the syntax error in your SQL query.
