Multiple Filter condition in scala and in and not in clause filter

I am trying to do a filter similar to below using scala

where col1 = 'abc' and col2 not in (0,4) and col3 in (1,2,3,4)

I tried writing something like this

val finalDf: DataFrame = 
    initDf.filter(col("col1") ="abc")
          .filter(col("col2") <> 0)
          .filter(col("col2") <> 4)
          .filter(col("col3") = 1 ||col("col3") = 2 ||col("col3") = 3 ||col("col3") = 4)

or

val finalDf: DataFrame = 
     initDf.filter(col("col1") ="abc") 
     && col("col2") != 0 && col("col2") != 4 
     && (col("col3") = 1 
     || col("col3") = 2 
     || col("col3") = 3 
     || col("col3") = 4))

both not seems to be working. Can anyone help me on this.

For col operators are a little bit different

For equality use ===

For Inequality =!=

If you want to use literals you can use lit function

Your example may look like this

dfMain.filter(col("col1") === lit("abc"))
          .filter(col("col2") =!= lit(0))
          .filter(col("col2") =!= lit(4))
          .filter(col("col3") === lit(1) || col("col3") === lit(2) ||col("col3") === lit(3) ||col("col3") === lit(4))

You can also use isin instead of this filter with multiply ors
