Incorrect syntax near 'error_keyword' - How to solve MySQL error: syntax error

Error is one of the problems that developers often encounter when writing MySQL query statements. One of the common errors is "Incorrect syntax near 'error_keyword'". This error message is very common and means that there is a syntax error in the MySQL query statement. In this article, we'll detail how to solve this problem and provide some concrete code examples.

First, let’s take a look at why this error occurs. MySQL query statements are written according to specific syntax rules. If there are any syntax errors in the code, MySQL will not be able to parse and execute the query correctly. For example, you might use the wrong keyword, forget to use commas to separate column names, or use the wrong quotes, etc.

To solve this problem, we provide the following common solutions:

1. Check the syntax carefully:
   First, carefully check the code for possible syntax errors. Make sure keywords, quotes, brackets, etc. are used correctly. A common mistake is to use incorrect bracket matching, such as forgetting to close the brackets in the query statement.
2. Use appropriate quotation marks:
   In MySQL, strings need to be enclosed in quotation marks. If you use strings in your query, make sure you use the correct quotes. In MySQL, you can enclose strings using single or double quotes. For example, the correct way to write it is: SELECT * FROM table WHERE column = 'value'.
3. Make sure the keywords are spelled correctly:
   MySQL has specific keywords for performing different operations, such as SELECT, INSERT, UPDATE, etc. Make sure you spell these keywords correctly in your query, otherwise you will get a grammatical error.
4. Use appropriate commas to separate column names:
   When referencing multiple column names in a query statement, be sure to use commas to separate the column names. For example, SELECT column1, column2 FROM table.

In addition to these common solutions, we also provide some specific code examples to help you better understand how to solve this problem:

Example 1: Wrong keyword Spelling

SELECT * FROM table WHERE colum = 'value';

Corrected code:

SELECT * FROM table WHERE column = 'value';

Example 2: Missing comma separated column names

SELECT column1 column2 FROM table;

Corrected code:

SELECT column1, column2 FROM table;

Example 3: Wrong quotation marks use

SELECT * FROM table WHERE column = "value';

Corrected code:

SELECT * FROM table WHERE column = 'value';

The above are some common problems and solutions that may cause MySQL to report an error "Incorrect syntax near 'error_keyword'". When encountering this error, carefully review your code and apply corrective actions if necessary. By using correct syntax and quotation marks, as well as spelling keywords correctly, you will be able to avoid such errors and execute your MySQL queries smoothly.
