JDBC Connection String Builder
Build a correct JDBC URL without memorizing each vendor's format. Choose the database, fill in host, port and database name, toggle SSL, and copy the connection string plus the matching driver class.
Do more than jdbc connection string builder — meet Chat2DB
Chat2DB is an AI-powered SQL client for Windows, macOS and Linux. Write SQL in natural language, format and optimize queries automatically, and manage MySQL, PostgreSQL, Oracle and 20+ other databases in one workspace.
How to use
- Choose your database — the default port fills in automatically.
- Enter host, port and database/service name, and toggle SSL if needed.
- Copy the generated JDBC URL and driver class into your application or IDE.
Frequently asked questions
What is a JDBC URL?
A JDBC URL tells a Java application how to reach a database: the protocol (jdbc:mysql:, jdbc:postgresql:...), the host and port, the database name, and optional parameters such as SSL settings.
Why does the SQL Server format look different?
SQL Server separates properties with semicolons (jdbc:sqlserver://host:1433;databaseName=mydb;encrypt=true) instead of the ?key=value&... query style used by MySQL and PostgreSQL, and Oracle thin URLs use @//host:port/service.
How can I test the connection quickly?
Paste the same host, port and credentials into Chat2DB — it connects to all of these databases with a built-in driver manager and shows precise errors if the connection fails.
