转换字符串并与DF列值Spark Scala进行比较

import org.apache.spark.sql.functions._

val df = spark.createDataFrame(Seq(
  ("John", "John Doe"),
  ("Jane", "Jane Smith"),
  ("Bob", "Bob Johnson")
)).toDF("name", "full_name")

val dfWithTransformedString = df.withColumn("transformed_name", lit("John Doe"))

val dfWithComparison = dfWithTransformedString.withColumn("is_equal", when(col("name") === col("transformed_name"), true).otherwise(false))

dfWithComparison.show()
