How can I easily insert a blob into a varbinary(MAX)
field?
举个例子:
我想插入的是:c:picture.png
该表是 mytable
该列是 mypictureblob
这个地方是 recid=1
thing I want to insert is: c:picture.png
the table is mytable
the column is mypictureblob
the place is recid=1
推荐答案
您可以在 SQL Server Management Studio 中使用 T-SQL 插入 varbinary(max) 字段,尤其是使用 OPENROWSET 命令.
You can insert into a varbinary(max) field using T-SQL within SQL Server Management Studio and in particular using the OPENROWSET commmand.
例如:
INSERT Production.ProductPhoto
(
ThumbnailPhoto,
ThumbnailPhotoFilePath,
LargePhoto,
LargePhotoFilePath
)
SELECT ThumbnailPhoto.*, null, null, N'tricycle_pink.gif'
FROM OPENROWSET
(BULK 'c:images ricycle.jpg', SINGLE_BLOB) ThumbnailPhoto

使用大值类型
请注意,在这种情况下,文件路径相对于目标 SQL 服务器,而不是您的客户端运行此命令.
Note that the file path in this case is relative to the targeted SQL server and not your client running this command.
