Connecting to an Informix data source
When accessing data from Informix using the included DataDirect ODBC Informix data driver, set the UseDelimitedIdentifier property to 1. To specify the property value for connection-string based designs, add the property UseDelimitedIdentifier=1 to the end of the connection string. To specify the property value for DSN‑based connections, perform the appropriate task for your operating system.
On a Windows system, go to the Windows ODBC registry entry:
HKLM\Software\ODBC\ODBC.ini\<DSN Name>
and set the value of UseDelimitedIdentifier to 1.
On a Linux system, edit the odbc.ini file, and add UseDelimitedIdentifier=1 to the DSN entry.
