@wafastudies Thanks for this video. So basically we can use Struct_type when we want to change/mention the datatype and with_column can be used to update/change/create new columns or values. Right?

[@vadderamu5422]

Thank you so much sir valued information. I have one query could you please help on the same? How to rename the existing column name?

[@NeumsFor9]

Does every additional df consume as much memory as the previous datsftame or is the memory based on the pointer arithmetic of the net effect of the overall columns?

[@ektashah7117]

If I am doing this it shows updated data at the time of df. show() but whenever we are checking db compass it shows that it is not updating. I tried to update it through overwrite then it deleted the table but not create a new one.Please help here.
