Hi @umatripathi ,

There are some conversions that do not support collapsed queries, you can refer to this document for details on which steps to take:
Query folding - Power Query | Microsoft Learn
If you need to change the data type, consider doing this in the database before importing the data into Power BI. 
Or as @Martin_D  put it, please use "Advanced Options" and enter a SQL query when connecting to the database. You can write SQL statements to import data and perform data type conversion in SQL queries.

If transformations are not folding and you would still prefer to execute them on the database server rather than in the Power Query engine, then you can put the native SQL query code into Power Query instead. The input field is in the Advanced options of the MySQL connector:
