Hi guys,
I'm currently trying to insert image into my SQL db. I have tried a number of methods that were posted online, and so far with no luck.
My current code reads:
Dim conn As New Data.SqlClient.SqlConnection()
conn.ConnectionString = ConfigurationManager.ConnectionStrings("MainDBConnection").ToString
conn.Open()
Dim cmd As New Data.SqlClient.SqlCommand("SP_SAVEImage", conn)
cmd.CommandType = Data.CommandType.StoredProcedure
Dim nUserID As New Data.SqlClient.SqlParameter("@.nUserID", Data.SqlDbType.Int)
nUserID.Value = "1"
Dim nAlbumID As New Data.SqlClient.SqlParameter("@.nAlbumID", Data.SqlDbType.Int)
nAlbumID.Value = "1"
Dim sDescription As New Data.SqlClient.SqlParameter("@.sDescription", Data.SqlDbType.VarChar, 50)
sDescription.Value = "image1"
Dim sImageName As New Data.SqlClient.SqlParameter("@.sImageName", Data.SqlDbType.VarChar, 50)
sImageName.Value = sImageName
Dim sImageType As New Data.SqlClient.SqlParameter("@.sImageType", Data.SqlDbType.VarChar, 50)
sImageType.Value = fileType
Dim sImageData As New Data.SqlClient.SqlParameter("@.sImageData", Data.SqlDbType.Image, uploadedFile.Length)
sImageData.Value = uploadedFile
cmd.Parameters.Add(nUserID)
cmd.Parameters.Add(nAlbumID)
cmd.Parameters.Add(sDescription)
cmd.Parameters.Add(sImageName)
cmd.Parameters.Add(sImageType)
cmd.Parameters.Add(sImageData)
Dim reader1 As Data.SqlClient.SqlDataReader
reader1 = cmd.ExecuteReader
Running through debug, everything runs up until the last line, where an error is caught saying : Failed to convert parameter value from a SqlParameter to a String
I reckon it's to do with the input sImageData being input as a byte array - but I can't seem to find a way around it.
Any help greatly appreciated!!
Dim sImageName As New Data.SqlClient.SqlParameter("@.sImageName", Data.SqlDbType.VarChar, 50)
sImageName.Value = sImageName
You are setting an SqlParameter equal to a string value. Must be a typeo. Fix and retry.
THANK YOU!!!!!!
I feel such an idiot now!! I've been looking at this code for so long I couldn't see the obvious.
I had honestly just given up on the idea of saving my data this way; but decided to check the post before going to bed - I can sleep well now knowing at least some of my code works! lol.
Cheers mate
