將localhost sql數據庫與OLEDB連接

Question

我有以下代碼使用VB.NET連接localhost數據庫和OLEDB。 以下是代碼：

Imports System.IO
Imports System.Data
Imports System.Data.OleDb

Module Module1
Public conn As OleDbConnection

Public Sub OpenConnection()

    conn = New OleDbConnection()

    If conn.State = ConnectionState.Closed Then

        Try
        conn.ConnectionString = "provider=MySQLProv; Data Source=mydbname; User Id=root; Password=password"

         conn.Open()

            MsgBox("Connected to DB")

Catch ex As OleDbException
                MessageBox.Show("Error Connecting to Database")
                conn.Close()
                conn.Dispose()
            End Try
        End If
    End Sub

運行時，錯誤“'MySQLProv'提供程序未在本地計算機上注冊。” 出現。 我已經安裝了MySQL Connector Net 6.5.7和MySQL Connector ODBC 5.3，但Visual Studios表示它沒有安裝。

我也嘗試過不同的連接字符串，但每個連接字符串都有錯誤：

            'conn.ConnectionString = "Driver={MySQL};SERVER=localhost;DATABASE=smsengine5;USER=root;PASSWORD=password"

            'conn.ConnectionString = "provider=MYSQLOLEDB; Driver={MySQL};SERVER=localhost;DATABASE=mydbname;USER=root;PASSWORD=password"

            'conn.ConnectionString = "provider=.NET Framework Data Provider for MySQL;*;Uid=root;Pwd=password;Database=mydbname;"

            'conn.ConnectionString = "provider=MySQLProv; Data Source=mydbname; User Id=root; Password=password"

            'conn.ConnectionString = "Driver={mysql};Server=localhost;PORT=3306;UI D=root;PWD=password;OPTION=16386"

            'conn.ConnectionString = "Provider=<<MySQLProv>>; Location=<<localhost>>; Data Source=<<mydbname>>; USER ID=<<root>>; PASSWORD=<<password>>; option=3;port=33 06;"

            'conn.ConnectionString = "Driver={MySQL ODBC 3.51 Driver};Server=localhost Database=mydbname; User=root; Password=password; Optio n=4;"

            'conn.ConnectionString = "Provider=MySQLProv.3.9;Location=<<localhost>>;Data Source=<<mydbname>>; USER ID=<<>root>>;Password=<<password>>;port=<<3306>>;"

            'conn.ConnectionString = "Provider=MySQL Provider; Data Source=localhost; User ID=root; Password=password; Initial Catalog=mydbname;"

            'conn.ConnectionString = "Server=localhost;Database=mydbname;Uid=User;Pwd=mypass; providerName=MySql.Data.MySqlClient"

            'conn.ConnectionString = "Driver={MySQL ODBC 3.51 Driver};Server=localhost;Database=mydbname; User=root;Password=myPassword;Option=3;"

            'conn.ConnectionString = "Provider=SQLOLEDB; Data Source=localhost; Initial Catalog=mydbname; User ID=root; Password=password;"

            'conn.ConnectionString = "Data Source=localhost:3306;Database=mydbname;User ID=root; Password=password;"

我也在我的項目中引用了Mysql.Data。

**我不想使用MySQL客戶端。

請幫忙。 謝謝

Answer 1

有使用OLEDB MySQL作為陳述三種連接字符串在這里 ：

標准

Server=myServerAddress;Database=myDataBase;Uid=myUsername;Pwd=myPassword;
MySQL

指定TCP端口

Server=myServerAddress;Port=1234;Database=myDataBase;Uid=myUsername;
Pwd=myPassword;

端口3306是默認的MySql端口。如果使用Unix套接字，則忽略該值。

多台服務器

使用此選項可連接到復制服務器配置中的服務器，而無需考慮要使用的服務器。

Server=serverAddress1, serverAddress2, serverAddress3;Database=myDataBase;
Uid=myUsername;Pwd=myPassword;

Answer 2

使用“provider = MSDataShape”解決
