Hey @DBUser2 

It looks that delete is not supported at all based on documentation:

Write-back
The Simba Apache Spark ODBC Connector supports translation for the following
syntax when connecting to a Spark Thrift Server instance that is running Spark 1.3 or
later:
l INSERT
l CREATE
l DROP
Spark does not support UPDATE or DELETE syntax.
If the statement contains non-standard SQL-92 syntax, then the connector is unable to
translate the statement to SQL and instead falls back to using HiveQL.
