Introduction to MySQL Error 1064
MySQL Error 1064 sometimes seems to be very difficult to understand. But, If we observe and have the knowledge about 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 error is represented with the help of error codes which are 4-digit numbers that range 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 the possible causes and solutions to it.
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 is not able to 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 must be bound with the rules of Mysql. The syntax error is similar to the grammar mistakes that occur in English or any other linguistic language where the sentences must be correct according to the rules of the grammar that are 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. We need to first read the error message that is thrown along with error code1064. This message provides useful information about where the error is occurring and why. Studying that part of the query, we can conclude where the query must have gone wrong provided if we are well aware of the SQL syntaxes.
The error message mostly uses the keywords like “at the line” or “near” to specify where exactly the MySQL is not able to parse the query. Manier times, the error message also suggests the possible solution to the error that has occurred. Like 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 of the possible causes that lead to a 1064 error in MySQL. They are as listed below
Commands may be typed incorrectly
Sometimes, the mistake may be done while typing the query like for example we may type SELECT instead of SELECT. Such types of errors arising due to typo mistakes can be prevented if we check our queries for any spelling mistakes before executing the queries. Also, there are many IDE’s and client-side tools for MySQL that provide the facility to check on the spellings and also parse the queries even before running them when we are typing the query on their editor pad. If the IDE you are using does not provide this type of checking, you can go searching with the settings or any other plugins that can be used to add this facility. Also, many online syntax checkers are available that will help to check the query syntax.
Deprecated commands may be used
It may happen sometimes that you must be using the commands that are absolute in your version or have been deprecated. Many commands are removed from the Mysql from time to time. We need to take a check on these commands. For example, the command for specifying the storage engine of the table was TYPE = before version 4.1 in MySQL. But in MySQL version 4.1 and above the TYPE command was declared as deprecated and in version5.1 it was completely removed and it was compulsory to use ENGINE = command instead of TYPE command in the Mysql versions 5.1 and higher.
Data required in the query may be missing
There can be a situation when you are adding the parameter values and certain values to the restrictions in the query during runtime and building the query statement dynamically. In such situations, it is necessary to make sure that the default value is given to the variables that are assigned in the query as sometimes these variables may not contain the expected value and remain blank which leads to incorrect construction of SQL query. For example, suppose in PHP language, you use the query like “SELECT uname, password FROM users WHERE uid=”. $SESSION[‘u_id’]. When the session variable u_id does not have any value and we have not initialized this variable to some default value then the query that will be built up, in the end, will be as follows – “SELECT uname,upassword FROM users WHERE uid=” that is completely incorrect as the data required for the query is missing. In our case, the value of uid to be mentioned in the WHERE clause for restriction is missing.
The reserved words may not be supported in MySQL version you are using
Sometimes the reserved words that we are using may be incorrect or not supported by the current version of the MYSQL you are using. Like sometimes we may forget to use the quotation mark or backticks in the keywords that are net or we may use camel case instead of keyword containing _ in it. All these mistakes in keywords spellings and deprecated or absolute keyword usage give errors with a 1064 error code.
WordPress data may be transferred in an incompatible mode
When we transfer the data and export it using WordPress database to some other server then it may lead to MYSQL error with error code 1064 if the database version and mode of compatibility that is being used are not the same as the current version of your database. In this situation, changing the database version to the current version, selecting the mode of compatibility while taking out the backup, and choosing the auto-detect file option of character set when restoring the database can help to solve this error.
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. Mysql error code 1064 is raised when there is an error in the syntax or some functionality being used is deprecated or absolute. We can determine and correct it if we study the message carefully, use good IDE for the detection of typos and parse errors, and review the query for mistakes in the query before execution.
