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; }
