这段代码中 X 被赋值给多个变量,如果您想让这些变量都赋相同的值,您可以改为以下写法:
```
DECLARE @x AS NUMERIC
SET @x = X
INSERT INTO [tewp].[dbo].[ReportData](SensorID,X,Y,Z,wTime,ReportKey,dX,dY,dZ,ToHoleTop,ToHoleBottom,LimitDamDepth,LimitSafeHeight,LimitBeachLength)
SELECT 62 AS SensorID, @x as Z, @x as Y, @x as Z, @x AS dX, @x AS dY, @x AS dZ, @x AS ToHoleTop, @x AS ToHoleBottom, @x AS LimitDamDepth, @x AS LimitSafeHeight, @x AS LimitBeachLength, CONVERT(char(19), aDatetime, 120) as wTime, CONVERT(char(10), aDatetime, 120) AS ReportKey
FROM [Proj].[dbo].[雨量计]
```
这样就可以将 X 的值赋给多个变量,并将它们插入到目标表中。

这个错误可能是由于你的数据类型不匹配导致的。在你的存储过程中,你正在尝试将一个 varchar 数据类型转换为 numeric 数据类型。你需要检查你的代码,确保你正在使用正确的数据类型进行转换。你可以使用 CAST 或 CONVERT 函数来显式地将数据类型转换为正确的数据类型。另外,你也可以检查你的输入数据,确保它们是正确的数据类型。
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
```
