Database client software allows you to communicate between a client application and the database or data warehouse. Install a database client on all ArcGIS client machines when connecting to the following:
| Database or data warehouse | Database client |
|---|---|
Amazon Redshift | Amazon Redshift ODBC driver |
Amazon Relational Database Service (RDS) for Oracle | Oracle Database Client |
Amazon RDS for SQL Server | Microsoft ODBC driver for SQL Server |
Autonomous Transaction Processing database in Oracle Cloud | Oracle Database Client |
Dameng | Dameng DM |
Google BigQuery | Magnitude Simba ODBC driver |
Google Cloud SQL for SQL Server | Microsoft ODBC driver for SQL Server |
IBM Db2 | IBM Data Server Runtime Client for Db2 |
Microsoft Azure SQL Database | Microsoft ODBC driver for SQL Server |
Microsoft Azure SQL Managed Instance | Microsoft ODBC driver for SQL Server |
Microsoft SQL Server | Microsoft ODBC driver for SQL Server |
Oracle | Oracle Database Client |
Oracle Co-managed Systems Virtual Machine DB Systems | Oracle Database Client |
SAP HANA | SAP HANA client |
SAP HANA Cloud | SAP HANA client |
Snowflake | Snowflake ODBC driver |
Teradata Data Warehouse Appliance | Teradata ODBC driver and associated files (GSS client and ICU library) |
Obtain the database client from the database or data warehouse vendor and follow their client installation instructions to set up the client on your computer. IBM Data Server Runtime Client for Db2 and the Windows version of the Microsoft ODBC driver for SQL Server are also available on My Esri.
For information on supported database client versions for the ArcGIS release you're using, see the ArcGIS system requirements for the database to which you need to connect.
To connect from 64-bit ArcGIS clients (such as ArcGIS Server or ArcGIS Pro), you must install 64-bit database clients.
Caveats
Note the following in regard to database clients and ArcGIS:
- No database client is required to connect to SQLite or a GeoPackage.
- ArcGIS clients include the files you need to connect to PostgreSQL, so you don't need to install a PostgreSQL client.
- ArcGIS no longer supports Oracle 11g clients. Even if you connect to an Oracle 11g database from ArcGIS, you must use a newer Oracle client.
