BEGIN INSERT INTO [tewp].[dbo].[ReportData] ( SensorID, X, Y, Z, wTime, ReportKey, dX, dY, dZ, ToHoleTop, ToHoleBottom, LimitDamDepth, LimitSafeHeight, LimitBeachLength ) SELECT 62 AS SensorID, CAST ( X AS X NUMERIC ), CAST ( X AS Y NUMERIC ), CAST ( X AS Z NUMERIC ), CAST ( X AS dX NUMERIC ), CAST ( X AS dY NUMERIC ), CAST ( X AS dZ NUMERIC ), CAST ( X AS ToHoleTop NUMERIC ), CAST ( X AS ToHoleBottom NUMERIC ), CAST ( X AS LimitDamDepth NUMERIC ), CAST ( X AS LimitSafeHeight NUMERIC ), CAST ( X AS LimitBeachLength NUMERIC ), CONVERT ( CHAR ( 19 ), aDatetime, 120 ) AS wTime, CONVERT ( CHAR ( 10 ), aDatetime, 120 ) AS ReportKey FROM [Proj].[dbo].[雨量计] END

根据你提供的 SQL 语句，你想要将 X 列的值转换为 NUMERIC 类型，并将转换后的值插入到 ReportData 表中的相应列中。同时，你还想将 aDatetime 列的值转换为字符类型，分别存入 wTime 和 ReportKey 列中。

对于将 X 列的值转换为 NUMERIC 类型的操作，你需要将 CAST 函数的语法进行修改，将 X 的数据类型从 X 修改为 NUMERIC，具体如下：

CAST ( X AS NUMERIC )

对于将 aDatetime 列的值转换为字符类型的操作，你可以使用 CONVERT 函数，并将第二个参数设置为 120，表示将日期时间转换为 yyyy-mm-dd hh:mi:ss 的格式。具体如下：

CONVERT ( CHAR ( 19 ), aDatetime, 120 )

最终的 SQL 语句如下所示：

BEGIN
	INSERT INTO [tewp].[dbo].[ReportData] (
		SensorID,
		X,
		Y,
		Z,
		wTime,
		ReportKey,
		dX,
		dY,
		dZ,
		ToHoleTop,
		ToHoleBottom,
		LimitDamDepth,
		LimitSafeHeight,
		LimitBeachLength
	)
	SELECT
		62 AS SensorID,
		CAST ( X AS NUMERIC ),
		CAST ( X AS NUMERIC ),
		CAST ( X AS NUMERIC ),
		CONVERT ( CHAR ( 19 ), aDatetime, 120 ) AS wTime,
		CONVERT ( CHAR ( 10 ), aDatetime, 120 ) AS ReportKey,
		CAST ( X AS NUMERIC ),
		CAST ( X AS NUMERIC ),
		CAST ( X AS NUMERIC ),
		CAST ( X AS NUMERIC ),
		CAST ( X AS NUMERIC ),
		CAST ( X AS NUMERIC ),
		CAST ( X AS NUMERIC )
	FROM
		[Proj].[dbo].[雨量计]
END
