Access Odoo Data as a Remote Oracle Database

Use the Oracle ODBC Gateway and Heterogeneous Services technology to access Odoo data from your Oracle system.

The Oracle Database Gateway for ODBC and Heterogeneous Services technology enable you to connect to ODBC data sources as remote Oracle databases. This article shows how to use the CData ODBC Driver for Odoo to create a database link from Odoo to Oracle and to query Odoo data through the SQL*Plus tool. You can also create the database link and execute queries from SQL Developer.

About Odoo Data Integration

Accessing and integrating live data from Odoo has never been easier with CData. Customers rely on CData connectivity to:

Access live data from both Odoo API 8.0+ and Odoo.sh Cloud ERP.
Extend the native Odoo features with intelligent handling of many-to-one, one-to-many, and many-to-many data properties. CData's connectivity solutions also intelligently handle complex data properties within Odoo. In addition to columns with simple values like text and dates, there are also columns that contain multiple values on each row. The driver decodes these kinds of values differently, depending upon the type of column the value comes from:
- Many-to-one columns are references to a single row within another model. Within CData solutions, many-to-one columns are represented as integers, whose value is the ID to which they refer in the other model.
- Many-to-many columns are references to many rows within another model. Within CData solutions, many-to-many columns are represented as text containing a comma-separated list of integers. Each value in that list is the ID of a row that is being referenced.
- One-to-many columns are references to many rows within another model - they are similar to many-to-many columns (comma-separated lists of integers), except that each row in the referenced model must belong to only one in the main model.
Use SQL stored procedures to call server-side RFCs within Odoo.

Users frequently integrate Odoo with analytics tools such as Power BI and Qlik Sense, and leverage our tools to replicate Odoo data to databases or data warehouses.

Getting Started

Connect to Odoo as an ODBC Data Source

Information for connecting to Odoo follows, along with different instructions for configuring a DSN in Windows and Linux environments.

To connect, set the Url to a valid Odoo site, User and Password to the connection details of the user you are connecting with, and Database to the Odoo database.

Windows

If you have not already, first specify connection properties in an ODBC DSN (data source name). This is the last step of the driver installation. You can use the Microsoft ODBC Data Source Administrator to create and configure ODBC DSNs.

Note: If you need to modify the DSN or create other Odoo DSNs, you must use a system DSN and the bitness of the DSN must match your Oracle system. You can access and create 32-bit DSNs on a 64-bit system by opening the 32-bit ODBC Data Source Administrator from C:\Windows\SysWOW64\odbcad32.exe.

Linux

If you are installing the CData ODBC Driver for Odoo in a Linux environment, the driver installation predefines a system DSN. You can modify the DSN by editing the system data sources file (/etc/odbc.ini) and defining the required connection properties.

/etc/odbc.ini


[CData Odoo Source]
Driver = CData ODBC Driver for Odoo
Description = My Description
User = MyUser
Password = MyPassword
URL = http://MyOdooSite/
Database = MyDatabase

For specific information on using these configuration files, please refer to the help documentation (installed and found online).

Set Connection Properties for Compatibility with Oracle

The driver provides several connection properties that streamline accessing Odoo data just as you would an Oracle database. Set the following properties when working with Odoo data in SQL*Plus and SQL Developer. For compatibility with Oracle, you will need to set the following connection properties, in addition to authentication and other required connection properties.

MapToWVarchar=False

Set this property to map string data types to SQL_VARCHAR instead of SQL_WVARCHAR. By default, the driver uses SQL_WVARCHAR to accommodate various international character sets. You can use this property to avoid the ORA-28528 Heterogeneous Services data type conversion error when the Unicode type is returned.
MaximumColumnSize=4000

Set this property to restrict the maximum column size to 4000 characters.
IncludeDualTable=True

Set this property to mock the Oracle DUAL table. SQL Developer uses this table to test the connection.

Linux Configuration

In Linux environments, Oracle uses UTF-8 to communicate with the unixODBC Driver manager, whereas the default driver encoding is UTF-16. To resolve this, open the file /opt/cdata/cdata-driver-for-odoo/lib/cdata.odbc.odoo.ini in a text editor and set the encoding.

cdata.odbc.odoo.ini


[Driver]
DriverManagerEncoding = UTF-8

Configure the ODBC Gateway, Oracle Net, and Oracle Database

Follow the procedure below to set up an ODBC gateway to Odoo data that enables you to query live Odoo data as an Oracle database.

Create the file initmyodoodb.ora in the folder oracle-home-directory/hs/admin and add the following setting:

initmyodoodb.ora
HS_FDS_CONNECT_INFO = "CData Odoo Sys"
Add an entry to the listener.ora file. This file is located in oracle-home-directory/NETWORK/admin.
If you are using the Database Gateway for ODBC, your listener.ora needs to have a SID_LIST_LISTENER entry that resembles the following:

listener.ora
SID_LIST_LISTENER = (SID_LIST = (SID_DESC = (SID_NAME = myodoodb) (ORACLE_HOME = your-oracle-home) (PROGRAM = dg4odbc) ) )
If you are using Heterogeneous Services, your listener.ora needs to have a SID_LIST_LISTENER entry that resembles the following:

listener.ora
SID_LIST_LISTENER = (SID_LIST = (SID_DESC = (SID_NAME = myodoodb) (ORACLE_HOME = your-oracle-home) (PROGRAM = hsodbc) ) )
Add the connect descriptor below in tnsnames.ora, located in oracle-home-directory/NETWORK/admin:

tnsnames.ora
myodoodb = (DESCRIPTION= (ADDRESS=(PROTOCOL=tcp)(HOST=localhost)(PORT=1521)) (CONNECT_DATA=(SID=myodoodb)) (HS=OK) )
Restart the listener.
Test the configuration with the following command:
tnsping myodoodb
Open SQL*Plus and create the database link with the command below:
CREATE DATABASE LINK myodoodb CONNECT TO "user" IDENTIFIED BY "password" USING 'myodoodb';

You can now execute queries in SQL*Plus like the one below (note the double quotation marks around the table name):


SELECT * from "res_users"@myodoodb WHERE id = '1';
