    Sure, below is a simple sample, you can test on it.

     

    let
	tsql=queryparameter,//query parameter is your t-sql string parameter
	Source= Sql.Database("ServerName", "databaseName", [Query=tsql])
in
    Source

Hi pratikthakor,

 

Yes, it is possible to use query parameter with t-sql query as optional parameter in sql connector.

 

AFAIK, current power bi not support dynamic table structure.(column amount, column name)

 

So if you change sql query on service side, you need to confirm result table has same structure, otherwise it will return error when refresh data.
