11                     GO
12                     create proc [dbo].[P_KillConnections] 
13                     @dbname varchar(200) 
14                     as
15                     declare @sql nvarchar(500) 
16                     declare @spid nvarchar(20) 
17                     declare #tb cursor for 
18                     select spid=cast(spid as varchar(20)) from master..sysprocesses where dbid=db_id(@dbname) 
19                     open #tb 
20                     fetch next from #tb into @spid 
21                     while @@fetch_status=0 
22                     begin
23                     exec('kill '+@spid) 
24                     fetch next from #tb into @spid 
25                     end close #tb deallocate #tb ";
26                    
27             //执行Sql语句
28             try
29             {
30                 result = DbHelperSQL.ExecuteSql(SqlStr);
31             }
32             catch (Exception e)
33             {
34                 ErrStr = e.Message;
35                 return -2;
36             }
37             return result;
38         }

 

但执行过程中出现以下错误

 

 

 以下是我在查询分析器中能正常使用的脚本代码。

 1  USE [RadarDataBase]
 2                      GO
 3                       SET  ANSI_NULLS  ON
 4                      GO
 5                       SET  QUOTED_IDENTIFIER  ON
 6                      GO
 7                      create proc [dbo].[P_KillConnections] 
 8                      @dbname varchar( 200 ) 
 9                       as
10                      declare @sql nvarchar( 500 ) 
11                      declare @spid nvarchar( 20 ) 
12                      declare #tb cursor  for  
13                       select  spid = cast(spid  as  varchar( 20 )) from master..sysprocesses where dbid = db_id(@dbname) 
14                      open #tb 
15                      fetch  next  from #tb into @spid 
16                       while  @@fetch_status = 0  
17                      begin
18                      exec( ' kill '+@spid) 
19                      fetch  next  from #tb into @spid 
20                       end  close #tb deallocate #tb  " ;

 

查询分析器是sql客户端，它可以识别go用来分批提交，但go不是sql语句，sql服务器不能识别所以不能用在程序中。

所以将带有GO的语句分成多条sql语句，执行多条SQL语句，实现数据库事务，代码如下：

 

 1    public   int  CreateDB_KillProc_proc()
 2          {
 3              List < string >  strSqls  =   new  List < string > ();
 4               int  result  =   0 ;
 5               string  SqlStr  =   "" ;
 6               // 组合Sql语句
 7              SqlStr  +=   " USE [RadarDataBase] " ;
 8              strSqls.Add(SqlStr);
 9              SqlStr  =   " SET ANSI_NULLS ON  " ;
10              strSqls.Add(SqlStr);
11              SqlStr  =   " SET QUOTED_IDENTIFIER ON   " ;
12              strSqls.Add(SqlStr);
13              SqlStr  =   @" create proc [dbo].[P_KillConnections] 
14                      @dbname varchar(200) 
15                      as
16                      declare @sql nvarchar(500)
17                      declare @spid nvarchar(20) 
18                      declare #tb cursor for
19                      select spid=cast(spid as varchar(20)) from master..sysprocesses where dbid=db_id(@dbname)
20                      open #tb
21                      fetch next from #tb into @spid
22                      while @@fetch_status=0 
23                      begin
24                      exec('kill '+@spid)
25                      fetch next from #tb into @spid 
26                      end close #tb deallocate #tb " ;
27              strSqls.Add(SqlStr);
28               // 执行Sql语句
29               try
30              {
31                  result  =  DbHelperSQL.ExecuteSqlTran(strSqls);// 这个函数功能是执行多条sql语句实现数据库事务
32              }
33               catch  (Exception e)
34              {
35                  ErrStr  =  e.Message;
36                   return   - 2 ;
37              }
38               return  result;
39          }
