Steps to reproduce:

1. Send Paramater as value for where section works.
2. Send it as part of table name, section from doesn't

Result:
Error from step 2:

"Failed to execute handler: failed to execute handler: failed to query: mssql: Must declare the table variable "@p1"."
Hardcoding the table name in the customquery returns the expected query result.

Using the @p1 parameter value somewhere else in the query like the coal_chamber.sql example works fine as well. But only not in the from section of the query.
