I am trying to insert an image into a VARBINARY(MAX) column. I get this error:
You do not have permission to use the bulk load statement.
Possibly one needs
ALTER ROLE [sysadmin] ADD MEMBER [user]
For example - in the current Linux version of SQL Server bulkadmin role is not supported and one needs to use a sysadmin to BULK INSERT. It is a known issue with SQL Server https://github.com/MicrosoftDocs/sql-docs/issues/4198 - SQL Server on Linux has permissions and roles that are not granular enough.
