SQL WHERE builder
Turn simple condition rows into a parameterized WHERE draft.
Inputs stay in your browser. Outputs placeholders and params and does not execute SQL.
Output is a parameterized WHERE draft; it is not executed and does not replace authorization checks.
How to use this tool
Turn simple condition rows into a parameterized WHERE draft.
Enter one field, operator, and value per line to generate a parameterized SQL WHERE clause and parameter list. Conditions join with AND; nested groups are not supported.
💡 3 Quick Steps to Get Started
For example: status = active or name contains Ada. Supported operators: =, !=, >, <, >=, <=, contains, starts_with, ends_with.
Choose the dialect for $1 or ? placeholders. Every condition joins with AND.
Bind the WHERE clause and parameter list through your database driver; do not replace placeholders by concatenating strings.
When it helps
Useful for support queries, internal tools, and data-filter drafts.
How it works
Outputs placeholders and params and does not execute SQL.
Worked example
Example: status = active becomes WHERE status = $1.
Limits and data handling
Only simple AND conditions are covered; review database dialect, allowed columns, and value types.
No. The SQL WHERE builder runs in the browser. Do not paste production secrets or unredacted personal data.

Workflow and limits
For example: status = active or name contains Ada. Supported operators: =, !=, >, <, >=, <=, contains, starts_with, ends_with.
Choose the dialect for $1 or ? placeholders. Every condition joins with AND.
Bind the WHERE clause and parameter list through your database driver; do not replace placeholders by concatenating strings.
OR, IN, BETWEEN, and IS NULL are not supported. NULL is treated as a literal string parameter, not automatically converted into a null check.
Field names are validated and values are parameterized. Check schema, permissions, and query semantics; this is not a complete SQL security review.
