这是在VB.NET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 ODBC.NET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
- 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")
