I have a multiple expressions which is stored as string like below

      CHECKFILTER1 = "trim(col(column)).rlike(REGEXFORINT) || col(column).isNull"
      CHECKFILTER2 = "when(trim(col(column)).rlike(REGEXFORINT) || df(column).isNull,null).otherwise(col(column))"
      CHECKFILTER3 = "when(trim(col(column)).rlike(REGEXFORINT) || df(column).isNull,null).otherwise(column)"

My requirement here is to execute these string expressions on a dataframe using spark dataframe API in scala.

I tried using below but this didn’t work
df.withColumn(column,expr(s”$column ${CHECKFILTER1}”)
