1、存儲過程
C#的代碼如下：
/// <summary>
/// 存儲過程參數結構
/// </summary>
public struct ProcParam
{
public string ParamName;
public string ParamValue;
public System.Data.SqlDbType ParamType ;
}
/// <summary>
/// 執(zhí)行一個返回數據集的存儲過程
/// </summary>
/// <param name="strProcName">存儲過程名稱</param>
/// <param name="alParamName" >參數名稱</param>
/// <param name="alParamValue" >參數值</param>
/// <param name="constring">數據連接串</param>
/// <returns></returns>
public static System.Data.SqlClient.SqlDataReader ExecProcedure(string strProcName,System.Collections.ArrayList alParamName,System.Collections.ArrayList alParamValue,string constring)
{
System.Data.SqlClient.SqlConnection cn=new System.Data.SqlClient.SqlConnection (constring);
cn.Open ();
System.Data.SqlClient.SqlCommand cmd=new System.Data.SqlClient. SqlCommand ();
cmd.Connection =cn;
cmd.CommandType =System.Data.CommandType.StoredProcedure ;
cmd.CommandText =strProcName;
for(int i=0;i<alParamName.Count ;i++)
{
System.Data.SqlClient.SqlParameter param=new System.Data.SqlClient.SqlParameter (alParamName[i].ToString (),alParamValue[i].ToString ());
cmd.Parameters.Add (param);
}
System.Data.SqlClient.SqlDataReader dr;
dr=cmd.ExecuteReader ();
return dr;
}
上述代碼可以執(zhí)行任意參數的存儲過程（返回一個數據集）
2、直接SQL命令
/// <summary>
/// 執(zhí)行一個返回字符串的SQL SCRIPT
/// </summary>
/// <param name="constring" >連接串</param>
/// <param name="SQL_COMMAND" >SQL命令</param>
/// <returns>返回數據集</returns>
public static string GetDataString(string SQL_COMMAND,string constring)
{
System.Data.SqlClient.SqlConnection cn=new System.Data.SqlClient.SqlConnection (constring);
cn.Open ();
System.Data.SqlClient.SqlCommand cmd=new System.Data.SqlClient. SqlCommand ();
cmd.Connection =cn;
cmd.CommandType =System.Data.CommandType.Text ;
cmd.CommandText =SQL_COMMAND;
string str="";
try
{
str=cmd.ExecuteScalar().ToString ();
}
catch(System.Data.SqlClient.SqlException e)
{
System.Diagnostics.Debug.WriteLine (e.Message );
}
catch(Exception ex)
{
System.Diagnostics.Debug.WriteLine (ex.Message );
}
return str;
}
/// <summary>
/// 執(zhí)行一個無返回的SQL
/// </summary>
/// <param name="SQL_COMMAND"></param>
/// <param name="constring"></param>
/// <returns></returns>
public static void Executesql(string SQL_COMMAND,string constring)
{
System.Data.SqlClient.SqlConnection cn=new System.Data.SqlClient.SqlConnection (constring);
cn.Open ();
System.Data.SqlClient.SqlCommand cmd=new System.Data.SqlClient. SqlCommand ();
cmd.Connection =cn;
cmd.CommandType =System.Data.CommandType.Text ;
cmd.CommandText =SQL_COMMAND;
try
{
cmd.ExecuteNonQuery ();
}
catch(System.Data.SqlClient.SqlException e)
{
System.Diagnostics.Debug.WriteLine (e.Message );
}
catch(Exception ex)
{
System.Diagnostics.Debug.WriteLine (ex.Message );
}
}
使用MySQL-Front連MySQL只要把連接的服務器設置為localhost,端口設置為3306,數據庫設置為MySQL就OK了，上面的都是默認的設置，如果要連接別的服務器的另外的數據庫只要更改這三個屬性就行了
