Frequently asked questions
What is the standard way to escape a single quote in SQL?
Double it: O'Brien becomes 'O''Brien'. This works in every SQL database. MySQL additionally accepts backslash escapes like \' by default.
Does escaping strings prevent SQL injection?
Escaping helps for ad-hoc statements, but the reliable protection is parameterized queries (prepared statements), which keep data out of the SQL text entirely. Use this tool for quick manual queries, not as an application security mechanism.
How do I avoid manual escaping day to day?
A database client like Chat2DB escapes values automatically when you edit data in the grid, and its AI assistant writes parameterized statements for your language and framework.
