database Data Connection node objects define the settings for connecting to and interacting with a database. These interactions may include conducting lookups, exports, or other actions that relate to database management systems (DBMS). Once configured, a Data Connection object can be referenced by other components in Grooper for various DBMS-related activities.
Grooper can connect to a Microsoft SQL Server or ODBC-compliant providers (such as Oracle, Db2, MySQL and PostgreSQL).
Data Connections are primarily used for two reasons in Grooper
- To validate data extracted from a document or to populate fields using values stored in a database.
- This is done using Database Lookups defined on Data Models.
- To export collected data to a database.
- This is done using Data Exports defined using Export Behaviors
How To
Create a Data Connection
Data Connections can be created in any Grooper Project. Please see Configuring a Data Connection.
Use a Data Connection for Database Lookups
Please see Database Lookup.
Use a Data Connection for Data Export
Please see Configuring Export Behaviors for Data Export.
Known Issues
The Grooper installer ships with various prerequisite components which are installed before the Grooper application. This includes CLR type mappings for various SQL data types. Without additional components installed, users may experience the following error when attempting to preview database tables with unsupported CLR Types (such as geometry and geography data types):
InvalidOperationException: DataReader.GetFieldType(24) returned null.
To support additional CLR Types (including geometry and geography data types), users need to install the following prerequisite from Microsoft:
Words of caution on ODBC Data Connections
|
⚠ |
BE AWARE: You will need to connect to an ODBC data source on both the web server and any machine hosting Activity Processing services ODBC data sources must be connected to from the Windows ODBC Data Sources Administrator before creating a Data Connection in Grooper. This must be done on the web server and any client machines hosting Activity Processing services.

BE AWARE: Not all ODBC databases are fully supported Grooper officially supports the following ODBC databases:
While other database versions may also function with ODBC, they could potentially encounter issues, particularly with more advanced features or newer updates. |
