Solution or Workaround
Using the ArcSDE C API to load raster data, SE_rastercolumn_create encountered a -193 error:
"Raster column has non-Null values or used as row_id column."
Cause:
The raster column is defined in the table with the NOT NULL constraint. Raster columns must allow NULLs.
Solution:
Alter the table to allow NULLs in the raster column.
