这是我改变数据格式
val df2resultTimestamp = finalXmlDf.withColumn("FilingDateTime_1", date_format(col("FilingDateTime_1"), "yyyy-MM-dd'T'HH:mm:ss'Z'"))
.withColumn("StatementDate_1", date_format(col("StatementDate_1"), "yyyy-MM-dd'T'HH:mm:ss'Z'"))
.withColumn("CapitalChangeAdjustmentDate_1", date_format(col("CapitalChangeAdjustmentDate_1"), "yyyy-MM-dd'T'HH:mm:ss'Z'"))
.withColumn("CumulativeAdjustmentFactor_1", regexp_replace(format_number($"CumulativeAdjustmentFactor_1".cast(DoubleType), 5), ",", ""))
这是我得到FilingDateTime_1列值更改的输出

值应为1984-02-14T03:00:00Z
我不知道我在这里失踪了什么..
答案 0 :(得分：1)
您只需添加to_timestamp内置功能，如下所示
val df2resultTimestamp = df.withColumn("FilingDateTime_1", date_format(to_timestamp(col("FilingDateTime_1"), "yyyy-MM-dd'T'HH:mm:ss"), "yyyy-MM-dd'T'HH:mm:ss'Z'"))
.withColumn("StatementDate_1", date_format(to_timestamp(col("StatementDate_1"), "yyyy-MM-dd'T'HH:mm:ss"), "yyyy-MM-dd'T'HH:mm:ss'Z'"))
.withColumn("CapitalChangeAdjustmentDate_1", date_format(to_timestamp(col("CapitalChangeAdjustmentDate_1"), "yyyy-MM-dd'T'HH:mm:ss"), "yyyy-MM-dd'T'HH:mm:ss'Z'"))
.withColumn("CumulativeAdjustmentFactor_1", regexp_replace(format_number($"CumulativeAdjustmentFactor_1".cast(DoubleType), 5), ",", ""))
应该为您提供正确的输出
