.Net中操作MySql数据库

来源:网络时间:2011-04-26 17:05:05

  这是在中为连接mysql中编写的一个类库。你可以使用这个类库直接操作MySql数据库

  在使用这个类库之前,你必须安装

  ODBC MYSQL 3.51下载地址:http://www.mysql.com/downloads/api-myodbc-3.51.html

  Driver 下载地址:http://www.microsoft.com/downloads/details.aspx?FamilyId=6CCD8427-1017-4F33-A062-D165078E32B1&displaylang=en

  在这个库中有三个类:

  ManipStringForMySQL: 此类修改SGBD的字符串

  MySQL_Requettes: 发送请求

  MySQL_Utils : 对SGBD数据进行测试

  下面是使用此类库操作MySql的一个例子

  //对DataSet进行操作 www.yestar2000iTbulo.comW7Cvs

  Public Shared Function MyODBCDataset(ByVal ReqSQL As String, _

         ByVal LaBase As String, ByVal Server As String, _

         ByVal Password As String, ByVal User As String, _

         ByVal NomDataSet As String) As DataSet

    ' Connexion à un server MySQL

    'avec le Driver ODBC 3.51 avec requette qui renvoie un dataset

    Dim MyConString As String = _

        "DRIVER={MySQL ODBC 3.51 Driver};SERVER=" & Server _

        & ";DATABASE=" & LaBase & ";UID=" & User _

        & ";PASSWORD=" & Password & ";OPTION=3;"

 

  Dim MyODBCConnexion As New OdbcConnection(MyConString)

    Try

        Dim ds As New DataSet()

        Dim cmd As OdbcDataAdapter = New

        OdbcDataAdapter(ReqSQL, MyConString)

        Dim MyCommand As New OdbcCommand()

        Dim MyDataReader As OdbcDataReader

        cmd.Fill(ds, NomDataSet)

        MyODBCConnexion.Close()

        Return ds

    Catch MyOdbcException As OdbcException

    '

      HttpContext.Current.Response.Write(MyOdbcException.ToString)

    Catch MyException As Exception

    '

      HttpContext.Current.Response.Write(MyException.ToString)

    End Try

End Function

    //对函数的调用

  Dim MonDatasetTemp As DataSet = MySQL_Requettes.MyODBCDataset(

               SQL,

               constantes.ODBCBase,

               constantes.ODBCServer,

               constantes.ODBCPwd,

               constantes.ODBCUser,

               "MonDataset")
