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 is a useful tool for developers and database administrators to validate the syntax and structure of their SQL code, and allows to find syntax errors. You can quickly and easily test your SQL query online directly in your browser, and thus save time .

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!
