What is SQL Checker and Validators?
SQL is a programming language which used to data managing and manipulation in RDBMS. When a developers write multiple SQL queries or codes it can be so complex and can have syntax errors, which can be cause of incorrect outcomes or system Crashes. To handle these perplex, There are so many SQL syntax checker and Validators which help to check the syntax of SQL queries,
Table of Contents
Simple cause of Syntax errors that can easily find by SQL Syntax Checker and Validators
- Extra commas or Missing commas in SQL query.
- Irrelevant uses of operators.
- Improper use of parentheses, quotes
- Misspelled of table names or keywords in query.
You can use various tools depending on your preferred environment. Here are a few options:
SQL linters:
There are several SQL linters available that can check the syntax of your queries and analyze SQL code for potential errors, style violations, or performance issues. They can help improve code quality, readability, and maintainability. Here are some popular SQL linters:
SQLLint
SQLfluff
SQLCop
SQLinForm
Redgate SQL Prompt
Below we have briefly explained SQL linters which have a common use in SQL Syntax Checker and Validators.
SQLLint:

Visual Studio Code (with SQL extensions):
Visual Studio Code is a lightweight and versatile code editor developed by Microsoft. With the addition of SQL extensions such as “SQL Server (mssql)” or “SQL Tools,” it can be turned into a powerful SQL development environment.
These IDEs often provide real-time syntax highlighting and error checking as you write your SQL queries.
Online SQL Validators
Online SQL validators are convenient tools for quickly checking the syntax and validity of SQL queries without the need to install any software locally. There are also various websites where you can paste your SQL code and have it validated instantly. Some examples include:
SQL Fiddle:
SQL Fiddle allows you to create, share, and run SQL queries against various database systems such as MySQL, PostgreSQL, SQL Server, and Oracle. It provides a simple interface for writing SQL queries and seeing the results.
SQL Validator:
SQL Validator is an online tool that checks the syntax of SQL queries and provides feedback on any errors or issues found. It supports various SQL dialects and provides helpful error messages to guide you in correcting your queries.
W3Schools SQL Validator:
W3Schools offers an online SQL validator as part of its SQL tutorial. You can paste your SQL code into the validator, and it will check the syntax for errors. Additionally, it provides an option to run the query against a sample database to see the results.
DB-fiddle:
DB-fiddle is a tool similar to SQL Fiddle that allows you to write and execute SQL queries against different database systems. It supports MySQL, PostgreSQL, SQLite, SQL Server, Oracle, and more. You can create and share fiddles containing your SQL code.
Rextester:
Rextester is an online compiler and executor for various programming languages, including SQL. You can write SQL queries in the provided editor and run them against different database systems. It also supports sharing your code snippets with others.
