Hi - Thank you for the clear explanation in your videos. I have a question regarding reading data from SQL Server. In my schema, I have multiple data types that are not supported in PySpark. Do I need to specify all of those data types manually like how you converted "int" to "IntegerType" or is there an alternative approach bro

Lets say tomorrow the file comes with few more added cols and it has to be handled, how do we do that ?

Hi bro I have one doubt inferschema detects schema automatically but here how it is changed year string, in the code u have given if(list_schema(i)(1)=="int"), here u gave integer but it comes string, listschema(i)=(listschema(i)(0), "integer"), could you please clarify my doubt

What is the use of metadata here? also why inferSchema is used lastly in spite of using schema?

Hi, this is not exactly dynamic schema allocation. Dynamic schema allocation shall happen without inferring schema.
Can you please update the video and code.
