Introduction to MySQL Error 1064
MySQL Error 1064 sometimes seems to be very difficult to understand. But, If we observe and know the type of errors and their causes, it will be easy to determine where the query statement is going wrong and how this error can be removed. MySQL errors are represented through error codes, which consist of 4-digit numbers ranging from 1000 to 2051. These error codes specify what type of error has occurred. In this article, we will learn about the most common error code that arises, that is, 1064, and its possible causes and solutions.
What is Error 1064 in MySQL?
Whenever an error with error code 1064 arises after the execution of the query statement in MySQL, the main reason is that the MySQL parser cannot parse the query due to some fault in the syntax of the query. The syntax of the query must be according to the Structured Query Language and bound with the rules of Mysql. A syntax error is similar to grammar mistakes in English or any other linguistic language where the sentences must be correct according to the grammar rules defined for that language. In MySQL, syntax errors fail to parse and consequently fail in the execution of the query statement.
Causes and solution to MySQL 1064 Error
There can be many causes that might be responsible for the 1064 error to occur. To address error code 1064, we must first read the error message accompanying it. This message provides valuable information about where the error is happening and why. By studying that part of the query, we can conclude where the query went wrong, assuming we understand the SQL syntaxes well.
The error message mainly uses keywords like “at the line” or “near” to specify exactly where MySQL cannot parse the query. Manier times, the error message also suggests the possible solution to the error that has occurred. Sometimes, it may say that we need to check our MySQL syntax with the manual for the version of Mysql we are using to see the correct syntax. We will discuss some possible causes that lead to a 1064 error in MySQL. Here is a list of the items below.
Commands may be typed incorrectly
Sometimes, a mistake may be made while typing the query. For example, we may type SELECT instead of SELECT. We can prevent such errors caused by typos by checking our queries for spelling mistakes before executing them. Also, many IDEs and client-side tools for MySQL provide the facility to check on the spellings and parse the queries before running them when we are typing them on their editor pad. If your IDE does not offer this type of checking, you can search for settings or plugins that add this feature. Also, many online syntax checkers are available to help check the query syntax.
Deprecated commands may be used
It may sometimes happen that you must be using the absolute commands in your version or have been deprecated. Mysql removes many commands from time to time. We need to take check on these commands. For example, the command for specifying the table’s storage engine was TYPE = before version 4.1 in MySQL. MySQL version 4.1 and above deprecated the TYPE command, and in version 5.1, it completely removed it. From MySQL version 5.1 onwards, using the ENGINE = command is mandatory instead of the TYPE command.
Data required in the query may be missing
There can be a situation when you add the parameter values and certain values to the query’s restrictions during runtime and dynamically build the query statement. In such situations, ensuring that the variables assigned in the query have default values becomes necessary. Sometimes, these variables may not contain the expected value and remain blank, which can result in the incorrect construction of the SQL query. For example, suppose in PHP language, you use a query like “SELECT uname, password FROM users WHERE uid=”. $SESSION[‘u_id’]. If the session variable “u_id” lacks a value and we have not initialized it to a default value, it will generate a completely incorrect query. It will be as follows: “SELECT uname, upassword FROM users WHERE uid=” because the necessary data for the query is missing. In our scenario, the value of “uid” that needs to be specified in the WHERE clause for restriction is absent.
The reserved words may not be supported in the MySQL version you are using
Sometimes, we may use incorrect or unsupported reserved words in our current version of MYSQL. Sometimes, we may forget to use the quotation mark or backticks in the net keywords or use camel case instead of the keyword containing _ in it. All these keyword spelling mistakes and deprecated or absolute keyword usage give errors with a 1064 error code.
WordPress data may be transferred in an incompatible mode
Suppose you transfer and export data from your WordPress database to another server. In that case, you may encounter an MYSQL error with code 1064 if the target database’s version and compatibility mode do not match your database’s current version. In this situation, changing the database version to the current version, selecting the compatibility mode while taking out the backup, and choosing the auto-detect file option of the character set when restoring the database can help solve this error.
Conclusion
Execution of Mysql queries might lead to errors if there is any mistake in the query due to some other cause and can be corrected by applying the appropriate solution. If a syntax error or a deprecated/obsolete functionality is used, MySQL will generate an error code 1064. We can determine and correct it if we study the message carefully, use a good IDE to detect typos, parse errors, and review the query for mistakes before execution.
