Answer 1

使用OPENROWSET:

INSERT MyTable (ImageColumnName) 
SELECT BulkColumn FROM OPENROWSET (BULK 'c:\myjpeg.jpg', SINGLE_BLOB) AS X

编辑哎呀,你使用2000 - 不支持以前的解决方案.你必须使用WRITETEXT:

CREATE TABLE MyTable 
(
    ID INT PRIMARY KEY IDENTITY (1,1), 
    ImageColumnName IMAGE NULL
)
GO

-- must insert a dummy value into the image column for TEXTPTR 
-- to work in next bit
DECLARE @RowId INT
INSERT MyTable (ImageColumnName) VALUES (0xFFFFFFFF)
SELECT @RowId = SCOPE_IDENTITY()

-- get a pointer value to the row+column you want to 
-- write the image to
DECLARE @Pointer_Value varbinary(16)
SELECT @Pointer_Value = TEXTPTR(ImageColumnName)
FROM MyTable
WHERE Id = @RowId

-- write the image to the row+column pointer
WRITETEXT MyTable.ImageColumnName @Pointer_Value 'c:\myjpeg.jpg'
