I am using a python script to populate a table with values I get from rasters files. I use arcpy.AddField_management to add a new column and arcpy.CalculateField_management to insert the values for the new column. The table has more than 450 columns and after executing arcpy.CalculateField_management I get the following error:

ExecuteError: ERROR 999999: Error executing function.
Underlying DBMS error [[Microsoft][SQL Server Native Client 11.0][SQL Server]Cannot create a row of size 8074 which is greater than the allowable maximum row size of 8060.] 
Failed to execute (CalculateField).

I can avoid this error executing in SQL Server:


Is there anyway to execute this SQL server instruction from the script or another equivalent way to avoid the error?
