DataReader.GetFieldType(59) Returned Null Error

Affected Software/Reports/DLL(s): Google Earth Location Report, VW_LOCATION, DT_GEOGRAPHY, and some graphic interfaces including GMS.

Affected Software Version: Professional

Symptoms: When running reports in EQuIS Professional, an error may be encountered that includes the following text with the exception message:

"DataReader.GetFieldType(59) returned null" or "DataReader.GetFieldType(2) returned null"

Cause/Details: The problem can occur because either the appropriate SQL Clr Data Type is not installed or is the wrong version. In older builds of EQuIS, this can occur when EQuIS Professional is installed via an .msi file rather than via the .exe as instructed here.

Note: It is only necessary to apply the hotfix if you see the error noted above.

Resolution/Workaround: Download and install the Microsoft SQL Server 2014 Feature Pack item. This fix can be applied to workstations where Microsoft SQL Server and Microsoft SQL Server Management Studio have not been installed.

4.After the download is complete, make sure to UNBLOCK the file using the instructions in this help article. After unblocking the file, execute it (will install SQL Server System CLR Types).

When you have completed these steps, reopen EQuIS Professional. The error should be resolved.
