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.
- 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.
- 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.
Summary
MySQL error 1064 is a SQL syntax error. 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. You can also view the MySQL error log or use the MySQL command line tool to troubleshoot. However, the best solution is to follow standard SQL syntax.

MySQL is an open source relational database management system, mainly used to store and retrieve data quickly and reliably. Its working principle includes client requests, query resolution, execution of queries and return results. Examples of usage include creating tables, inserting and querying data, and advanced features such as JOIN operations. Common errors involve SQL syntax, data types, and permissions, and optimization suggestions include the use of indexes, optimized queries, and partitioning of tables.

MySQL is an open source relational database management system suitable for data storage, management, query and security. 1. It supports a variety of operating systems and is widely used in Web applications and other fields. 2. Through the client-server architecture and different storage engines, MySQL processes data efficiently. 3. Basic usage includes creating databases and tables, inserting, querying and updating data. 4. Advanced usage involves complex queries and stored procedures. 5. Common errors can be debugged through the EXPLAIN statement. 6. Performance optimization includes the rational use of indexes and optimized query statements.

MySQL is chosen for its performance, reliability, ease of use, and community support. 1.MySQL provides efficient data storage and retrieval functions, supporting multiple data types and advanced query operations. 2. Adopt client-server architecture and multiple storage engines to support transaction and query optimization. 3. Easy to use, supports a variety of operating systems and programming languages. 4. Have strong community support and provide rich resources and solutions.

InnoDB's lock mechanisms include shared locks, exclusive locks, intention locks, record locks, gap locks and next key locks. 1. Shared lock allows transactions to read data without preventing other transactions from reading. 2. Exclusive lock prevents other transactions from reading and modifying data. 3. Intention lock optimizes lock efficiency. 4. Record lock lock index record. 5. Gap lock locks index recording gap. 6. The next key lock is a combination of record lock and gap lock to ensure data consistency.

The main reasons for poor MySQL query performance include not using indexes, wrong execution plan selection by the query optimizer, unreasonable table design, excessive data volume and lock competition. 1. No index causes slow querying, and adding indexes can significantly improve performance. 2. Use the EXPLAIN command to analyze the query plan and find out the optimizer error. 3. Reconstructing the table structure and optimizing JOIN conditions can improve table design problems. 4. When the data volume is large, partitioning and table division strategies are adopted. 5. In a high concurrency environment, optimizing transactions and locking strategies can reduce lock competition.

In database optimization, indexing strategies should be selected according to query requirements: 1. When the query involves multiple columns and the order of conditions is fixed, use composite indexes; 2. When the query involves multiple columns but the order of conditions is not fixed, use multiple single-column indexes. Composite indexes are suitable for optimizing multi-column queries, while single-column indexes are suitable for single-column queries.

To optimize MySQL slow query, slowquerylog and performance_schema need to be used: 1. Enable slowquerylog and set thresholds to record slow query; 2. Use performance_schema to analyze query execution details, find out performance bottlenecks and optimize.

MySQL and SQL are essential skills for developers. 1.MySQL is an open source relational database management system, and SQL is the standard language used to manage and operate databases. 2.MySQL supports multiple storage engines through efficient data storage and retrieval functions, and SQL completes complex data operations through simple statements. 3. Examples of usage include basic queries and advanced queries, such as filtering and sorting by condition. 4. Common errors include syntax errors and performance issues, which can be optimized by checking SQL statements and using EXPLAIN commands. 5. Performance optimization techniques include using indexes, avoiding full table scanning, optimizing JOIN operations and improving code readability.
