SQL error

[JYOTIPRAKASH_2023]

Seeing this strange error now and then - transient error 

 Error SQL Execute :Microsoft ODBC Driver 17 for SQL Server : Internal Query Processor Error : The query processor could not obtain access to the required interface

Getting this error for some tables and getting results on other tables using the same ODBC driver for SQL server

is it possible that SQL Server is unavailable because of the network or downtime?

[JYOTIPRAKASH_2023]

If the server is down , then the other tables will not be accessible 

it is giving error only for few tables

This a SQL error pointing to something upstream in the DB. This does not seem to be an Alteryx based error. I would recommend you flag this to your SQL Server team to look at the internal error logs.
