SQL syntax checker

 

SQL query



SQL checker allows to check your SQL query syntax, it focuses on MySQL dialect (MySQL syntax checker). You can valide the syntax of your queries and find the syntax errors easily (the errors are highlighted).

User guide

To check syntax code:

  • First, Drag and drop your SQL file or copy / paste your request directly into the editor above.
  • Finally, you must click on "Check SQL syntax" button to display if there is an syntax error in your code.

You can click on "Format SQL query" to make your query more readable. This simplifies the correction.

SQL (Structured Query Language) is a domain-specific language used in relational databases. It is useful in handling structured data.

When working on a large SQL query, it is sometimes difficult to find where a syntax error is.

SQL error checker tool allows to find syntax errors. You can test your SQL query online directly in your browser.

If a syntax error is detected in your request, then the line in error is highlighted (rather useful for large sql requests). Frequent errors: forgetting to close parentheses, typology error of a keyword, omission of a keyword, ...

It is not necessarily easy to start in SQL, even for developers (it has nothing to do with programming languages). Even knowing the syntax of SQL, there is still a lot to learn to use the full power of SQL!

It checks the MySQL dialect because it is the most popular database. Mysql shares a significant part of its sql syntax with other databases (But there are of course differences with other databases like postgres, db2, ...). If you think it would be interesting to make it compatible with other databases, let me known via a comment.

Hoping that this little tool will be useful to developers and database administrators. It is a simple but effective tool :)

If you think of new features, do not hesitate to add a comment. I do not have a lot of time but I will do my best.

This tool uses the library SQL parser. This library has been used by phpMyAdmin since version 4.5!

OMG thank you for real!!!! I was getting a sql error syntax, and i spent literally 3 days trying to find the error.
I asked help at so many people, but none was helpful, due to complexety of my project and database design.
I also was trying programming foruns but this problem was too way specific for explain...
Once more...THANK YOU!!!
