   Your parameterized query and the screenshot bot look correct, but there 
could be subtle issues that we're missing from the limited information here.

them as literal strings
   
   That's because that is what happens. The variables in your query are parsed 
before the query is sent to the query as a sql string. The variable doesn't 
prevent any SQL injection or similar. Try hovering over your variables to see 
what their exact values are, write your parsed SQL to the logs with a Write To 
Leg etc to troubleshoot and to make sure the SQL is exactly what you expect it 
to be.
   
   An alternative approach could be to pass data from fields with the "insert 
data from transform" option, but you'll need to prepare your input stream 
correctly in that case. Check the docs and the examples in the samples project. 
   
   What you're trying to do is a common use case and is widely used, it 
shouldn't be too much of a problem to get it to work.
