I am using ArcPy to run through all of the spatial views in an enterprise GDB, register them with the GDB, and assign domains to the registered view. It runs great for most of the views in the GDB, but 5 of our 35 views fail with the titular error.

I've tried several suggested fixes, including

  • Turned off background geoprocessing
  • Cleared temp folder C:\Users\\AppData\Local\Temp
  • Checked additional log files (e.g., C:\Users\\AppData\Local\ESRI): empty
  • Check for NULL geometries in underlying SQL tables: don't have any
  • Exported view to shapefile (Feature class to feature class): it's valid
  • We don't have any user-defined data types
  • Deleted and recreated view
  • CAST bit to smallint for "Repaired" column in CREATE VIEW statement

RDBMS - MSSQL, version 14.0.17289.0

SDE - SQL Server Enterprise Geodatabase, version 10.5.1

    The bit datatype isn't directly supported by ArcGIS. The doc indicates the bit should be "viewable", but registering it is a deeper level of complexity. You can try casting it to smallint in view creation.

  • No dice. In my CREATE VIEW statement, I used CAST(CR.Repaired AS smallint) AS Repaired

    It's not an issue of whether the database is geodatabase-enabled (which is the term of art -- 'SDE' no longer exists), just that it's in a different database. I remember there being a reason why this cannot be supported, but don't remember the particulars (this would be an issue for Esri Tech Support).

    I got on with support, and the issue was unrelated to all of the above information. The SQL data type "date" is not supported by Esri. Changed to "datetime" in SQL, and they register now!

    An example of infamous esri's "catch all and return silly error code" error handling. Try to check if geometries are valid, e.g. SELECT * FROM TABLE_OR_VIEW WHERE Shape.STIsValid()=0 Nov 26, 2019 at 16:15

Closing this question. Word of advice: check you SQL data types, as unsupported types, such as "date" can cause ERROR 999999.
