Using Vanna with MSSQL

[duartespc]

I'm using Vanna connected to a sample Microsoft SQL server and I'm having some trouble with the SQL generated by Vanna when asking the train for X top Customers or Y top songs or Z top sales. The generated SQL always uses function LIMIT which is correct when using SQLite or MySQL, but it should use SELECT TOP instead when using SQL server. This causes an error, of course. I tried setting SQL example queries using the correct format in the training data but even when I ask one of the questions that I've set as an example it always tries to use LIMIT instead of SELECT TOP. I believe it is incompatible with MSSQL. Any ideas?
