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" )
