SQL Escape

Unsupported input

The tool may reject input that does not match the expected content, structure, or file type.

Fix: Confirm the tool input requirements and paste the correct type of data.

Incomplete values

Missing fields or partial content can block processing or produce weak results.

Fix: Provide the full required input before running the tool.

Copying placeholder content

Sample or placeholder values can lead to output that looks valid but is not ready for real use.

Fix: Replace placeholders with your actual values before relying on the result.

Is the escape in SQL Escape round-trip safe?

Yes. Escaping and then unescaping the same string with the matching tool returns the original byte-for-byte. If you see drift, the input likely contained already-escaped sequences that are being double-escaped — decode once first.

Does SQL Escape handle Unicode and emoji correctly?

Yes. Input is treated as UTF-16 code points, so characters outside the BMP (emoji, CJK extensions) escape into the correct surrogate pairs or \uXXXX sequences for the target language.

Should I rely on SQL Escape to prevent SQL injection or XSS?

SQL Escape is a developer utility for reading and editing escaped strings. For production code, always use parameterized queries (for SQL) and context-aware templating (for HTML) — manual escaping is a last resort.

Does SQL Escape match what the standard library in my language does?

Output is designed to match the behavior of the canonical escape/unescape functions in the target language (e.g., JSON.stringify for JSON, StringEscapeUtils in Java, htmlspecialchars in PHP). Edge cases like null bytes and control characters are documented in the tool UI.

How does SQL Escape handle existing backslashes in my input?

Existing backslashes are doubled on escape (\\ → \\\\) and halved on unescape. That's the behavior you want — it guarantees round-trip safety even if the input already contains escape sequences meant for a different language.
