SQL Formatter FAQ and Usage Guide
How to use Parameter Extractor?
Automatically finds and lists all parameters used in your SQL query. Supports various parameter formats:
- :param - Colon style (Named Parameter)
- @param - At sign style (SQL Server)
- ? - Question mark style (Positional Parameter)
- $1, $2 - Dollar style (PostgreSQL)
When to use IN List Builder?
Useful when converting a list of values into SQL IN clause format. For example, quickly convert a list copied from Excel or text files into SQL IN format.
Example: apple, banana, cherry → ('apple', 'banana', 'cherry')
Why is LIKE Escape needed?
In SQL LIKE clauses, % and _ are wildcard characters.
To search for these characters literally, you need to escape them.
%- Matches zero or more characters_- Matches exactly one character
Example: "50% off" → "50\\% off" (escaped with backslash)
Is my data safe?
Yes! All processing happens only in your browser. SQL queries and data are never sent to any server and are not stored anywhere.
