Difference between filter and where in scala spark sql

Question

I\'ve tried both but it works same

example

val items =  List(1, 2, 3)

using filter

employees.filter($\"emp_id\".         


        

Answer 1

just FYI,

maxTsunx.filter(r => r.get(0) == 1)

maxTsunx.where(col("ticker_id")===1)

or

maxTsunx.filter(col("ticker_id")===1)

In first case, passing function to filter function

In second case, passing condition expression (either string or column type) to filter or where function. Physical plan 2 is also possible by replacing where with filter function.
