Class Library for MySQL request

Introduction

This is a class library in VB.NET made for access on MySQL databases. You can use this library without creating functions for working on the databases.

For using this library, you must install :

and the

In this library, you have 3 classes:

  • ManipStringForMySQL: This class modifies the string for the SGBD
  • MySQL_Requettes: This class makes the request on the SGBD
  • MySQL_Utils : This class makes tests on the data of the SGBD

Visual Studio project screenshot

An example of the function with a dataset holding the results of the query:

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

The call of this function may be like that:

Dim MonDatasetTemp As DataSet = MySQL_Requettes.MyODBCDataset(
               SQL,
               constantes.ODBCBase, 
               constantes.ODBCServer, 
               constantes.ODBCPwd, 
               constantes.ODBCUser, 
               "MonDataset")

Conclusion

This library is the first example I made for the MySQL use in my ASP.NET solutions. I hope it can be easy for use in your projects.
