C#执行SQL脚本文件（三中方法）

方法一：osql.exe(这种方式最简单，但貌似微软以后会取消这个功能，改为SqlCmd了)

最简单的方法就是调用 osql.exe .

具体方法如下(以sql server200 数据库为例):

            try
            {
                System.Diagnostics.Process pr = new System.Diagnostics.Process();
                pr.StartInfo.FileName = "osql.exe ";
                pr.StartInfo.Arguments = "-U sa -P sa -d master -s 127.0.0.1 -i Sql.sql";
                pr.StartInfo.UseShellExecute = false;
                pr.StartInfo.RedirectStandardOutput = true;  //重定向输出
             
                pr.StartInfo.WindowStyle = System.Diagnostics.ProcessWindowStyle.Hidden;//隐藏输出窗口
                pr.Start();
                
                System.IO.StreamReader sr = pr.StandardOutput;
                Console.WriteLine(sr.ReadToEnd());
   
                pr.WaitForExit();
                pr.Close();
            }
            catch(Exception err)
            {
                MessageBox.Show(err.ToString());
            }

以下是osql的一些参数用法:

用法: osql                   [-U 登录 ID]          [-P 密码]
  [-S 服务器]                [-H 主机名]           [-E 可信连接]
  [-d 使用数据库名称]        [-l 登录超时值]       [-t 查询超时值]
  [-h 标题]                  [-s 列分隔符]         [-w 列宽]
  [-a 数据包大小]            [-e 回显输入]         [-I 允许带引号的标识符]
  [-L 列出服务器]            [-c 命令结束]         [-D ODBC DSN 名称]
  [-q "命令行查询"]          [-Q "命令行查询" 并退出]
  [-n 删除编号方式]          [-m 错误级别]
  [-r 发送到 stderr 的消息]  [-V 严重级别]
  [-i 输入文件]              [-o 输出文件]
  [-p 打印统计信息]               [-b 出错时中止批处理]
  [-X[1] 禁用命令，[退出的同时显示警告]]
  [-O 使用旧 ISQL 行为禁用下列项]

方法二：

让C#程序直接执行sql脚本文件,类似SSMS直接打开sql文件并执行一样,搜索了一下结果还真有,不过需要借用mssql的几个类库及命名空间:

Microsoft.SqlServer.ConnectionInfo.dll

Microsoft.SqlServer.Smo.dll

--------------------------------------------

using Microsoft.SqlServer.Management.Common;

using Microsoft.SqlServer.Management.Smo;

这里有一个小插叙,对于vs2008里可以直接引用这个这两个类库,但在vs2010里的引用就无法找到这两个类库了(不知道微软是怎么考虑的)

还好我电脑vs2008和vs2010都安装了

不过我还是避易就难的讲一下,vs2010在引用里无法找到这两个类库,那我们就想办法找到它,首先我电脑安装了mssqlserver2008 ,

我去X:\Program Files\Microsoft SQL Server\100\SDK\Assemblies 找到

Microsoft.SqlServer.ConnectionInfo.dll

Microsoft.SqlServer.Smo.dll

Microsoft.SqlServer.Management.Sdk.Sfc.dll(这个一定要考到你的程序目录,但你可以不引用)

然后手动添加应用,第三个dll一定要引用,不然会报错

代码如下：

//补卡操作
         private void PatchCard()
         {
             string path = System.Environment.CurrentDirectory;
             string CardNo = txtCardNo.Text.Trim();
             string connectonstring=ConfigurationManager.AppSettings["connectionString"].ToString();
             if(CardNo==null||CardNo=="")
             {
                 MessageBox.Show("卡号不能为空!");
                 return;
             }
             if(!path.EndsWith(@"\"))
             {
                 path += @"\";
             }
             path+="补蓝鲸卡.sql";    //获取脚本位置
             if (File.Exists(path))
             {
                 FileInfo file = new FileInfo(path);
                 string script = file.OpenText().ReadToEnd();
                 script=script.Replace("H00001", CardNo);  //替换脚本里的参数
                 try
                 {
                       //执行脚本
                    SqlConnection conn = new SqlConnection(connectonstring);
                    Microsoft.SqlServer.Management.Smo.Server server = new Server(new ServerConnection(conn));
                    int i= server.ConnectionContext.ExecuteNonQuery(script);
                    if (i == 1)
                    {
                        MessageBox.Show("恭喜!\n"+CardNo+" 补卡成功!","成功");
                        txtCardNo.Text = "";
                        CreateLog(CardNo, true);
                    }
                    else
                    {
                        MessageBox.Show("@_@ 再试一次吧!","失败");
                    }
                     
                 }
                 catch (Exception es)
                 {
                     MessageBox.Show(es.Message);
                     CreateLog(CardNo + "  " + es.Message, false);
                 }
             }
             else
             {
                 MessageBox.Show("脚本不存在!");
                 return;
             }
         }

方法三： 执行sql语句（最麻烦）

代码 

public static int ExecuteSqlScript(string sqlFile)
{
    int returnValue = -1;
    int sqlCount = 0, errorCount = 0;
    if (!File.Exists(sqlFile))
    {
        Log.WriteLog(string.Format("sql file not exists!", sqlFile));
        return -1;
    }
    using (StreamReader sr = new StreamReader(sqlFile))
    {
        string line = string.Empty;
        char spaceChar = ' ';
        string newLIne = "\r\n", semicolon = ";";
        string sprit = "/", whiffletree = "-";               
        string sql = string.Empty;
        do
        {
            line = sr.ReadLine();
            // 文件结束
            if (line == null) break;
            // 跳过注释行
            if (line.StartsWith(sprit) || line.StartsWith(whiffletree)) continue;
            // 去除右边空格
            line = line.TrimEnd(spaceChar);
            sql += line;
            // 以分号(;)结尾，则执行SQL
            if (sql.EndsWith(semicolon))
            {
                try
                {
                    sqlCount++;
                    SqlHelper.ExecuteNonQuery(sql, null);
                }
                catch (Exception ex)
                {
                    errorCount++;
                    Log.WriteLog(sql +  newLIne + ex.Message);  
                }                        
                sql = string.Empty;
            }
            else
            {
                // 添加换行符
                if(sql.Length > 0) sql += newLIne;
            }
        } while (true);
    }
    if (sqlCount > 0 && errorCount == 0)
        returnValue = 1;
    if (sqlCount == 0 && errorCount == 0)
        returnValue = 0;
    else if (sqlCount > errorCount && errorCount > 0)
        returnValue = -1;
    else if (sqlCount == errorCount)
        returnValue = -2;
    return returnValue;
}
