Does this tool provide SQL formatting and syntax checking?

Yes. It instantly checks for syntax errors and includes an automatic SQL formatter (beautifier) that organizes indentation and capitalization for better readability.

Can it help with SQL performance tuning and optimization?

Absolutely. The AI analyzes your query for performance bottlenecks like missing indexes or inefficient joins and suggests concrete tuning improvements to speed up execution.

Which databases are supported? Does it support BigQuery?

We support MySQL, PostgreSQL, Oracle, SQL Server, SQLite, and Google BigQuery. For BigQuery, it specifically warns about high-cost queries and suggests partitioning or clustering strategies.

Is there a security check for SQL injection?

Yes. The tool performs a security audit to detect potential SQL injection vulnerabilities and provides secure code examples using prepared statements.

Fix SQL Errors Instantly with AI-Powered Debugging

"SQL Error Fixer" interprets error messages from your console or logs, identifies the root cause, and instantly generates corrected SQL code. It's a free debugging tool fully compatible with major databases like MySQL, PostgreSQL, Oracle, and SQL Server.

Common Errors and Solutions for Major Databases

Each database has unique error codes and specifications. Our tool understands these "dialects" and provides appropriate fixes.

MySQL / MariaDB

Identifies causes for common errors like Error 1064 (Syntax error), Error 1213 (Deadlock), and Error 1452 (Foreign key constraint fails).

Oracle Database

Explains cryptic ORA codes such as ORA-00904 (Invalid identifier), ORA-00942 (Table not found), and ORA-01403 (No data found) in plain English.

PostgreSQL

Pinpoints the exact location of issues from messages like syntax error at or near, permission denied, or relation does not exist.

SQL Server (T-SQL)

Provides correct syntax for errors like Invalid object name and The multi-part identifier could not be bound common in T-SQL.

Troubleshooting Beyond Syntax

AI logically analyzes complex errors caused not just by typos, but by data integrity issues or permission settings.

1. Foreign Key Constraint Violations

Errors occurring during data insertion or deletion. The AI suggests solutions based on data dependencies, such as missing parent records or existing child records.

2. Permission Denied / Access Denied

If a correct SQL query fails to execute, user permissions might be the issue. The AI advises on necessary GRANT commands or what to ask your administrator.

3. Ambiguous Column References

Common in JOIN queries. The tool teaches you how to properly alias tables when multiple tables share column names.

4. Data Type Mismatches

Errors caused by inserting strings into number fields or incorrect date formats. We suggest appropriate casting functions and format corrections.
