How it works
How to turn a list into an SQL IN clause
The builder separates each value, formats it for the selected type, removes optional duplicates, and joins the tokens inside IN parentheses.
Paste the filter values
Use one value per line, commas, or semicolons and select the matching input format.
Choose the value type
Automatic mode leaves canonical numbers unquoted and quotes other values as text.
Add an optional column
Enter a column name to create column IN (...), with an optional WHERE prefix.
Review before running SQL
Copy the clause into your query only after checking identifiers, NULL logic, and the target database dialect.
Quick example
Build a status filter
The example escapes O'Brien correctly and prefixes the list with WHERE customer_name.
Common questions
SQL IN clause builder FAQ
How are apostrophes escaped?
For single-quoted text, an apostrophe is doubled. O'Brien becomes 'O''Brien', which is the standard SQL string-literal escape.
Does IN (NULL) find database NULL values?
Usually not. SQL NULL comparisons require IS NULL. The tool warns when a literal NULL appears so you can add the correct logic.
Can the builder validate a complete SQL query?
No. It formats a value list only. Always validate the final query, table and column identifiers, permissions, and database-specific syntax before execution.
Are database values uploaded?
No. Values are formatted in your browser. Avoid sharing backups that contain sensitive production data.
