Connection is very slow in SQL 2016

Hi Team,

We have one application that runs from Jboss server, but while connecting to DB server it will run some batch processes , which is taking more the 4 ms. but they wanted to have connection less than 1ms..

After long struggle we found that the script in batch process using different datatypes. like Varchar, but in databases the column has Nvarchar.. 

We have asked them to update all the datatypes to match database datatypes. Finally we achieved to get connection less than 1ms..

After few days, they started some updates using scheduler.. which is taking more time.. again we found the same kind of datatypes mismatch...

Here I just wanted to know, is there any script or tool that identifies or advise datatypes mismatch between the queries and database that runs...?
