通过执行SQL脚本配置数据库
use master exec sp_attach_db @dbname=N'数据库名 ',@filename1=N'数据库文件地址',@filename2=N'日志文件地址'
或
private void ExecuteSql(string connString,string DatabaseName,string sql)
{
using(SqlConnection conn=new SqlConnection(connString))
{
SqlCommand cmd=new SqlCommand(sql,conn);
conn.Open();
cmd.Connection.ChangeDatabase(DatabaseName);
cmd.ExecuteNonQuery();
conn.Close();
}
}
string connString=string.Format("server={0};user id={1};password={2}",this.Context.Parameters["server"],this.Context.Parameters["user"],this.Context.Parameters["pwd"]);
//根据输入的数据库名称建立数据库
ExecuteSql(connString,"master","create database "+this.Context.Parameters["dbname"]);
//调用osql执行脚本
string cmd=string.Format(" -S{0} -U{1} -P{2} -d{3} -i{4}db.sql",this.Context.Parameters["server"],this.Context.Parameters["user"],this.Context.Parameters["pwd"],this.Context.Parameters["dbname"],this.Context.Parameters["targetdir"]);
System.Diagnostics.Process sqlProcess=new Process();
sqlProcess.StartInfo.FileName="osql.exe";
sqlProcess.StartInfo.Arguments=cmd;
sqlProcess.StartInfo.WindowStyle=ProcessWindowStyle.Hidden;
sqlProcess.Start();
sqlProcess.WaitForExit();//等待执行
sqlProcess.Close();

配置文件如下：
<?xml version="1.0" encoding="utf-8" ?>
<ServerConfig>
<ServerName>localhost</ServerName>
<DataBase>tttttt</DataBase>
<UserId>sa</UserId>
<PassWord>sa</PassWord>
</ServerConfig>
保存为ServerConfig.xml
放到Bin/Debug/里面
调用如下：
DBAccess.ExecuteSqlFile(@"E:\My Document\MySql\test1.sql");
补充：.NET技术 , ASP.NET
