I am trying to parse this select statement

SELECT system_user

but the method TSQLStatementReader.ParseStatements() throws

Object reference not set to an instance of an object.

Kindly help me out if I am missing something or that’s the expected behavior. This is how I’m doing:

string sqlText = @"SELECT system_user;";

var statements = TSQLStatementReader.ParseStatements(sqlText);

I am using nuget package version: 2.1.0

interestingly if I change the select statement to this

SELECT system_user from tbl;

I just added a FROM clause and it works, it gives me the statement and tokens.

@muneeebsheikh , I pushed a new build, v2.2.1, and verified the functionality is now updated with the version pulled back from NuGet.
