本文实例讲述了C#中实现一次执行多条带GO的sql语句。分享给大家供大家参考。具体如下：
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Collections;
using System.Text.RegularExpressions;
using System.Data.SqlClient;
namespace ConsoleApplication1
{
class Program
{
//注： 在cmd.ExecuteNonQuery()是不允许语句中有GO出现的， 有则出错。
static string connectionString = "server=20111011-2204\\SQLSERVER2008;uid=ecuser;pwd=1234;database=Stu;" ;
static void Main( string [] args)
{
string sql =
@"Alter table Student add DateBak varchar(16)
go
Update Student set DateBak = convert(char,getdate(),101)
go
Update Student set Memo = DateBak
go
Alter table Student drop column DateBak
go
" ;
Console.WriteLine( "1. 不用事务：" );
ExecuteSqlWithGo(sql);
Console.WriteLine( "2. 用事务：" );
ExecuteSqlWithGoUseTran(sql);
Console.ReadLine();
}
public static void ExecuteSqlWithGo(String sql)
{
int effectedRows = 0;
using (SqlConnection conn = new SqlConnection(connectionString))
{
conn.Open();
SqlCommand cmd = new SqlCommand();
cmd.Connection = conn;
try
{
//注： 此处以 换行_后面带0到多个空格_再后面是go 来分割字符串
String[] sqlArr = Regex.Split(sql.Trim(), "\r\n\\s*go" , RegexOptions.IgnoreCase);
foreach ( string strsql in sqlArr)
{
if (strsql.Trim().Length > 1 && strsql.Trim()!= "\r\n" )
{
cmd.CommandText = strsql;
effectedRows = cmd.ExecuteNonQuery();
}
}
}
catch (System.Data.SqlClient.SqlException E)
{
throw new Exception(E.Message);
}
finally
{
conn.Close();
}
}
}
public static void ExecuteSqlWithGoUseTran(String sql)
{
using (SqlConnection conn = new SqlConnection(connectionString))
{
conn.Open();
SqlCommand cmd = new SqlCommand();
cmd.Connection = conn;
SqlTransaction tx = conn.BeginTransaction();
cmd.Transaction = tx;
try
{
//注： 此处以 换行_后面带0到多个空格_再后面是go 来分割字符串
String[] sqlArr = Regex.Split(sql.Trim(), "\r\n\\s*go" , RegexOptions.IgnoreCase);
foreach ( string strsql in sqlArr)
{
if (strsql.Trim().Length > 1 && strsql.Trim() != "\r\n" )
{
cmd.CommandText = strsql;
cmd.ExecuteNonQuery();
}
}
tx.Commit();
}
catch (System.Data.SqlClient.SqlException E)
{
tx.Rollback();
throw new Exception(E.Message);
}
finally
{
conn.Close();
}
}
}
}
}
希望本文所述对大家的C#程序设计有所帮助。
