Designed for safer SQL work
Your real database stays disconnected.
SQL Mocker does not request or store database credentials and never connects to your database. Users provide schema metadata only, such as table names, column names, data types, and relationships, so SQL can be generated against a safe replica.
No credentials
No usernames, passwords, connection strings, or server access details.
No live connection
Users run any metadata script themselves inside their own database tool.
Metadata only
SQL is generated from structure, not from private production rows.
Frequently Asked Questions
+What does SQL Mocker do?
SQL Mocker helps you create SQL from natural-language questions by using a safe schema replica made from table names, column names, data types, and relationships.
+Does SQL Mocker connect to my real database?
No. SQL Mocker does not request database credentials and does not connect to your live database. You provide schema metadata, then SQL Mocker generates SQL against that structure.
+What information do I need to upload?
Usually table names, column names, data types, primary keys, and relationships. You can upload a schema file, paste metadata, build a schema manually, or generate an extraction script to run yourself.
+Does SQL Mocker use real production data?
No. The app generates dummy data from your schema so you can test prompts and inspect results without exposing real records.
+Can I use SQL Mocker with existing SQL scripts?
Yes. You can upload pre-existing SQL and ask the assistant to explain, review, improve, format, convert, troubleshoot, or map the output columns and joins.
+Why choose SQL Mocker over other SQL AI generators?
Many SQL AI tools either connect directly to your database or generate queries from prompts without first giving you a safe place to test the logic. SQL Mocker uses your schema, relationships, and sample data context to help generate, test, refine, and troubleshoot SQL before you use it in your real database.
+Where are saved projects stored?
Saved projects are stored locally in your browser on your device. You can create a backup file from History to keep a copy on your PC.
+Which database systems does it support?
SQL Mocker can work with schema metadata from common systems such as SQL Server, PostgreSQL, Oracle, MySQL, Snowflake, BigQuery, SQLite, and other SQL-style databases.
+Why review schema and relationships before asking questions?
The assistant needs accurate tables, columns, keys, and joins to generate useful SQL. Reviewing the schema helps avoid missing columns, wrong joins, and unsafe aggregations.
