Question

我使用sql server调用google maps api并获取gps位置的数据。它工作正常，但最近我的存储过程调用失败，出现此错误

0x8004271F 
ODSOLE Extended Procedure 
The source data specified for this string or binary column or parameter is too long.

当google返回位置数据的“船载”时，似乎达到了字符数限制。

到目前为止，这就是我所说的：

-- Select dbo.fnGetAddressFromGPS('33.83528299,-118.28754585')  

-- -- GO
Declare @GPS VarChar(50)
Set @GPS = '34.55,-118.50'
DECLARE @URL VarChar(4000)
DECLARE @win int 
DECLARE @hr  int 
DECLARE @text varchar(8000)

Set @URL = 'http://maps.googleapis.com/maps/api/geocode/xml?latlng=' + @GPS + '&sensor=false'


Set @URL = 'http://maps.googleapis.com/maps/api/geocode/xml?latlng=34.5566767,-118.50677688&sensor=false'
Set @URL = 'http://maps.googleapis.com/maps/api/geocode/json?  latlng=34.5566767,-118.50677688&sensor=false'

EXEC @hr=sp_OACreate 'WinHttp.WinHttpRequest.5.1',@win OUT 
IF @hr <> 0 EXEC sp_OAGetErrorInfo @win 

EXEC @hr=sp_OAMethod @win, 'Open',NULL,'GET',@url,'false'
IF @hr <> 0 EXEC sp_OAGetErrorInfo @win 

EXEC @hr=sp_OAMethod @win,'Send'
IF @hr <> 0 EXEC sp_OAGetErrorInfo @win 

EXEC @hr=sp_OAGetProperty @win, 'ResponseText',@text OUTPUT
IF @hr <> 0 EXEC sp_OAGetErrorInfo @win

EXEC @hr=sp_OADestroy @win 
--IF @hr <> 0 EXEC sp_OAGetErrorInfo @win 



Select @Text As 'GoogleResult'
Return



IF CHARINDEX('ZERO_RESULTS', @text) > 0
Select 'No Address Found'


Declare @i Int
Declare @j Int
Declare @Address VarChar(150)

SELECT @i = CHARINDEX('<formatted_address>', @Text);
SELECT @j = CHARINDEX('</formatted_address>', @Text);

SELECT @i = CHARINDEX('"formatted_address" : "', @Text);
Select @i
Return


If @j-@i-Len('<formatted_address>') <= 0 
Select @Address = 'N/A'
Else
Select @Address = SubString(@text, @i+Len('<formatted_address>'), @j-@i-    Len('<formatted_address>'))

--Select @Address

Select @Address

我想要做的是将谷歌的返回数据限制为仅格式化的地址部分，这是我真正需要的，但我没有在文档中的任何地方找到如何做这样的事情。我能想到的另一件事就是截断结果数据，但我现在无法解决这个问题。任何帮助将不胜感激。

这里有趣的部分是插入表格：

DECLARE @resTbl AS TABLE（结果NVARCHAR（MAX））

INSERT @resTbl EXEC @ HttpWinRequest = sp_OAGetProperty @win，'ResponseText'

SET ANSI_NULLS ON
GO
SET QUOTED_IDENTIFIER ON
GO

ALTER PROCEDURE dbo.usp_http_get
    /*
sp_configure 'show advanced options', 1;
GO
RECONFIGURE;
GO
sp_configure 'Ole Automation Procedures', 1;
GO
RECONFIGURE;
GO
*/
    @url VARCHAR(8000)
AS
BEGIN
    SET NOCOUNT ON;

    DECLARE @win int, @HttpWinRequest  int

DECLARE @resTbl  AS TABLE (result NVARCHAR(MAX))



EXEC @HttpWinRequest=sp_OACreate 'WinHttp.WinHttpRequest.5.1',@win OUT

IF @HttpWinRequest <> 0 EXEC sp_OAGetErrorInfo @win
EXEC @HttpWinRequest=sp_OAMethod @win, 'Open',NULL,'GET',@url,'false'

IF @HttpWinRequest <> 0 EXEC sp_OAGetErrorInfo @win EXEC @HttpWinRequest=sp_OAMethod @win,'Send'


IF @HttpWinRequest <> 0 EXEC sp_OAGetErrorInfo @win

INSERT @resTbl EXEC @HttpWinRequest=sp_OAGetProperty @win, 'ResponseText'

IF @HttpWinRequest <> 0 EXEC sp_OAGetErrorInfo @win
EXEC @HttpWinRequest=sp_OADestroy @win

IF @HttpWinRequest <> 0 EXEC sp_OAGetErrorInfo @win

SELECT * FROM @resTbl
END
GO

EXEC usp_http_get @url = 'http://www.yahoo.com' -- varchar(8000)

sql server - 谷歌地图api返回太多数据
