Download GoogleCouldSpanner JDBC Driver
What Is a JDBC Driver?
A JDBC driver is a Java library file (.jar) that enables Java applications — including DbSchema — to communicate with a database over a standard API. The driver translates generic JDBC calls into the network protocol understood by GoogleCouldSpanner, so you never have to write low-level socket code. Drivers are typically distributed by the database vendor or as open-source projects.
Understanding the JDBC URL
Every JDBC driver identifies the target database through a connection URL. The URL encodes the hostname, port, database name, and any driver-specific parameters as a single string. The exact syntax varies per driver — the details for GoogleCouldSpanner are listed in the section below.

Google Cloud Spanner is a globally distributed, horizontally scalable relational database service that provides strong consistency and ACID transactions across geographic regions. It combines the benefits of relational databases (SQL, transactions) with the scale of NoSQL systems.

DbSchema and Google Cloud Spanner
DbSchema connects to Cloud Spanner using the Google JDBC driver and renders interleaved tables and foreign key relationships in the schema diagram. Use the SQL Editor to write Spanner SQL with array and struct type support.

Explore GoogleCouldSpanner Visually with DbSchema
Once the JDBC driver is configured, DbSchema connects to your GoogleCouldSpanner database and gives you a full graphical workbench — no command-line required. Available as a free Community Edition and a full-featured PRO Edition. No registration needed to get started.
Interactive ER Diagrams
Reverse-engineer your GoogleCouldSpanner schema into a drag-and-drop ER diagram. Arrange tables visually, add new columns, define foreign keys, and let DbSchema generate the DDL — all without writing SQL by hand.
Visual Query Builder
Compose GoogleCouldSpanner queries by clicking on tables and columns — no SQL knowledge required. Add joins, filters, groupings, and aggregations through a point-and-click interface, then copy the generated SQL or run it directly against the live database.
Relational Data Explorer
Browse GoogleCouldSpanner table data and follow foreign key relationships across tables in a single view. Edit cells inline, filter rows, and paginate through large datasets — all without leaving the explorer.
Schema Synchronization
Compare your GoogleCouldSpanner schema across development, staging, and production environments. DbSchema generates the exact ALTER statements needed to close the gap and lets you review every change before executing — reducing the risk of unintended schema drift.
SQL Editor
Write and execute GoogleCouldSpanner queries in the integrated SQL editor with schema-aware autocomplete, syntax highlighting, and instant result display. Run scripts, inspect execution plans, and export results to CSV or JSON from a single interface.
HTML Schema Documentation
Generate a static HTML site documenting every table, column, type, index, and relationship in your GoogleCouldSpanner schema. Share it with your team or embed it in your project wiki — no extra tooling required.
