SQL IN List Builder
Turn newline- or comma-separated values into SQL IN (...) literal syntax.
How to use
- Enter values, choose the formatting mode and deduplication option, then run.
Capabilities and scope
A dedicated runner offers string, number, and auto modes plus deduplication, and escapes apostrophes in strings by doubling them.
How it works
Items are trimmed and filtered, optionally deduplicated with Set, then strings are quoted, numbers remain numeric, and auto mode can emit NULL.
Example
alpha and O'Reilly become ('alpha', 'O''Reilly').
Useful for
- Prepare a small manual value list for an SQL IN clause
Before you use it
- This does not replace parameter binding and large lists are better handled through database/application query mechanisms.
Frequently asked questions
Can I rely on this alone to prevent SQL injection?
No. Production code should use parameterized queries rather than trusting generated SQL text.
