Question

我创建了一个存储过程;它成功执行但在手动执行时显示错误。

这是我的存储过程

USE [chandru]
GO
SET ANSI_NULLS ON
GO
SET QUOTED_IDENTIFIER ON
GO
alter procedure [dbo].[Insert_BandWidthDetails]          
@CurrentState nvarchar(50),@Process nvarchar(100),@DateTime nvarchar(100),@IPaddress nvarchar(50),@UploadedBytes nvarchar(max),@DownloadedBytes nvarchar(max),@Duration nvarchar(200),@FileSize nvarchar(max),@StreamId nvarchar(100),@PlayerId nvarchar(100),
@UserName nvarchar(200),@UserId nvarchar(200),@CountryName nvarchar(100),@RegionName nvarchar(100),@Latitude nvarchar(100),@Longitude nvarchar(100),@City nvarchar(100)           
as          
begin    


declare @Sql nvarchar(max)     

set @Sql='declare @countbandwidthtable int  select @countbandwidthtable=COUNT(*) from BandWidth'+@UserName+@UserId+
   +'if(@countbandwidthtable>0)
    begin
        declare @count int  select @count=COUNT(*) from BandWidth'+@UserName+@UserId+' where CurrentState='''+@CurrentState+''' and Process='''+@Process+''' and DateTime='''+@DateTime+''' and IPaddress='''+@IPaddress+''' and UploadedBytes='''+@UploadedBytes+''' and DownloadedBytes='''+@DownloadedBytes+''' and Duration='''+@Duration+''' and FileSize='''+@FileSize+''' and StreamId='''+@StreamId+''' and PlayerId='''+@PlayerId+''' and UserName='''+@UserName+''
        +'if(@count=0)          
        begin          
            insert into BandWidth'+@UserName+@UserId+' values('''+@CurrentState+''','''+@Process+''','''+@DateTime+''','''+@IPaddress+''','''+@UploadedBytes+''','''+@DownloadedBytes+''','''+@Duration+''','''+@FileSize+''','''+@StreamId+''','''+@PlayerId+''','''+@UserName+''','''+@CountryName+''','''+@RegionName+''','''+@Latitude+''','''+@Longitude+''','''+@City+''')       
        end         
    end
else
    begin
        select * into BandWidth'+ @UserName+ cast(@UserID as nvarchar(max)) +' from BandWidthSample where 1=2
       insert into BandWidth'+@UserName+@UserId+' values('''+@CurrentState+''','''+@Process+''','''+@DateTime+''','''+@IPaddress+''','''+@UploadedBytes+''','''+@DownloadedBytes+''','''+@Duration+''','''+@FileSize+''','''+@StreamId+''','''+@PlayerId+''','''+@UserName+''','''+@CountryName+''','''+@RegionName+''','''+@Latitude+''','''+@Longitude+''','''+@City+''')      
    end '     
 exec(@Sql)
end

执行此存储过程后，命令成功，现在我正在插入：

Insert_BandWidthDetails 'stream','play','11:17:00','10.0.3.0','12344','1234','2.09','22','1','11223','sample','31','india','asd','23','23','chennai'

我收到错误

Msg 102，Level 15，State 1，Line 1
  '＆gt;'附近的语法不正确。
  Msg 102，Level 15，State 1，Line 5
  'stream'附近的语法不正确
  Msg 105，Level 15，State 1，Line 11
  字符串'）结束后的未闭合引号。

我不知道如何清除此错误，我在“＆gt;”附近未发现任何错误这个符号，你们可以帮我解决这个错误吗？

Answer 1

除了每个用户只有一个表的设计之外，您的问题是第一行SQL在IF语句之前没有空格。如果您想在SQL中使用换行符，则需要添加+ CHAR(10)并且不要在代码中直接使用换行符。

如果要保留动态SQL，我建议将set语句重新格式化如下：

set @Sql='declare @countbandwidthtable int' + CHAR(10) + 
         'select @countbandwidthtable=COUNT(*) from BandWidth' + @UserName + @UserId + CHAR(10) +
         'if(@countbandwidthtable>0)' + CHAR(10) +
           'begin' + CHAR(10) +
             'declare @count int' + CHAR(10) +
             'select @count=COUNT(*) from BandWidth'+@UserName+@UserId+' where CurrentState='''+@CurrentState+''' and Process='''+@Process+''' and DateTime='''+@DateTime+''' and IPaddress='''+@IPaddress+''' and UploadedBytes='''+@UploadedBytes+''' and DownloadedBytes='''+@DownloadedBytes+''' and Duration='''+@Duration+''' and FileSize='''+@FileSize+''' and StreamId='''+@StreamId+''' and PlayerId='''+@PlayerId+''' and UserName='''+@UserName+'' + CHAR(10) +
             'if(@count=0)' + CHAR(10) +
               'begin' + CHAR(10) +
                 'insert into BandWidth'+@UserName+@UserId+' values('''+@CurrentState+''','''+@Process+''','''+@DateTime+''','''+@IPaddress+''','''+@UploadedBytes+''','''+@DownloadedBytes+''','''+@Duration+''','''+@FileSize+''','''+@StreamId+''','''+@PlayerId+''','''+@UserName+''','''+@CountryName+''','''+@RegionName+''','''+@Latitude+''','''+@Longitude+''','''+@City+''')' + CHAR(10) +
               'end' + CHAR(10) +
           'end' + CHAR(10) +
         'else' + CHAR(10) +
           'begin' + CHAR(10) +
             'select * into BandWidth'+ @UserName+ cast(@UserID as nvarchar(max)) +' from BandWidthSample where 1=2' + CHAR(10) +
             'insert into BandWidth'+@UserName+@UserId+' values('''+@CurrentState+''','''+@Process+''','''+@DateTime+''','''+@IPaddress+''','''+@UploadedBytes+''','''+@DownloadedBytes+''','''+@Duration+''','''+@FileSize+''','''+@StreamId+''','''+@PlayerId+''','''+@UserName+''','''+@CountryName+''','''+@RegionName+''','''+@Latitude+''','''+@Longitude+''','''+@City+''')' + CHAR(10) +
            'end' + CHAR(10)

但是，如果可能的话，我强烈建议您只使用一个包含保存UserName和UserId的列的BandWidth表。那么你根本不需要动态SQL。

尝试进行更改：

下面

declare @count int  select @count=COUNT(*) from BandWidth'+@UserName+@UserId+' where CurrentState='''+@CurrentState+''' and Process='''+@Process+''' and DateTime='''+@DateTime+''' and IPaddress='''+@IPaddress+''' and UploadedBytes='''+@UploadedBytes+''' and DownloadedBytes='''+@DownloadedBytes+''' and Duration='''+@Duration+''' and FileSize='''+@FileSize+''' and StreamId='''+@StreamId+''' and PlayerId='''+@PlayerId+''' and UserName='''+@UserName+''

到

declare @count int  select @count=COUNT(*) from BandWidth'+@UserName+@UserId+' where CurrentState='''+@CurrentState+''' and Process='''+@Process+''' and DateTime='''+@DateTime+''' and IPaddress='''+@IPaddress+''' and UploadedBytes='''+@UploadedBytes+''' and DownloadedBytes='''+@DownloadedBytes+''' and Duration='''+@Duration+''' and FileSize='''+@FileSize+''' and StreamId='''+@StreamId+''' and PlayerId='''+@PlayerId+''' and UserName='''+@UserName+''''

在@userName之后，最后查看2个新的'。这是唯一的变化。告诉我它是否有效

我创建了一个存储过程，同时执行没有错误，但手动运行它显示错误
