Question

我创建了一个新的SQL Server本地数据库，其中包含一个名为drink的表。我使用Microsoft Visual Studio 2008。

在表格中我定义了以下列：

id [int], kind [varchar], year [datatime], image [image]

我想将图片插入image栏，但我不知道该怎么做。

我需要这个专栏，因为我想使用VB.NET在DataGridView中显示所有数据

感谢您的帮助！

Answer 1

使用openrowset可以将图像插入数据库：

insert into tableName (id,kind,ImageColumn) 
SELECT 1,'JPEG',BulkColumn 
FROM Openrowset( Bulk '<Path of the image>', Single_Blob) as img

这对我有用......

Imports System.Data.Sql
Imports System.IO
Imports System.drawing

Module Module1

    Private Const _ConnectString As String = "your connection string here"

     Sub Main()
        Dim MyImage As Image = Image.FromFile("RandomImage.jpg")
        Dim Id As Long = 1
        SaveDrinkImage(MyImage, Id)
     End Sub

    Sub SaveDrinkImage(MyImage As Image, Id As Long)

        Dim ImageBytes(0) As Byte
        Using mStream As New MemoryStream()
                 MyImage.Save(mStream, MyImage.RawFormat)
                 ImageBytes = mStream.ToArray()
        End Using

        Dim adoConnect = New SqlClient.SqlConnection(_ConnectString)
        Dim adoCommand = New SqlClient.SqlCommand("UPDATE [drink] SET [image]=@MyNewImage WHERE [id]=@id", adoConnect)

        With adoCommand.Parameters.Add("@MyNewImage", SqlDbType.Image)
            .Value = ImageBytes
            .Size = ImageBytes.Length
        End With
        With adoCommand.Parameters.Add("@id", SqlDbType.BigInt)
            .Value = Id
        End With

        adoConnect.Open()
        adoCommand.ExecuteNonQuery()
        adoConnect.close()

    End Sub

End Module

Answer 3

有两种方法。您可以将图像存储为数据库中的blob，也可以将路径（字符串）存储到图像文件中。有一个答案可以讨论这个问题：Storing images in SQL Server?

Answer 4

试试这个：

Sub SaveDrinkToDB(name As String, imageFilePath As String)
    Using cn = New SqlConnection("connection string here")
        cn.Open()
        Using cmd = New SqlCommand("INSERT INTO Drink (Name, Image) Values(@Name,@Image)", cn)
            cmd.Parameters.AddWithValue("@name", name)
            cmd.Parameters.AddWithValue("@Image", File.ReadAllBytes(imageFilePath))
            cmd.ExecuteNonQuery()
        End Using
    End Using
End Sub

用法：

    SaveDrinkToDB("Milk", "c:\drink.png")

Answer 5

USE [database_name]
GO
INSERT INTO [schema].[tablename]([property1],[property2],[Property3],[Image])
     VALUES
           ('value','value','value','C:\pathname.jpg')
GO
