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
(本文来源于图老师网站,更多请访问http://m.tulaoshi.com/bianchengyuyan/)//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")
