Operator '&' is not defined for string "Insert into Table_Name(XYZ_" and type 'Byte()'

I get this error →

Operator '&' is not defined for string "Insert into SP_Master_Entry (SP_" and type 'Byte()'.

I think this error is caused near dr(SP_Photo) and am very much new to VB.NET

mainModule.DatabaseNonQuery("
    Insert into SP_Master_Entry 
     (SP_ID, SP_Name, Gender, Date_Of_Birth, Date_Of_Join, Branch_ID,
      SP_Area_ID, SP_Address1, SP_Address2, SP_Address3, PIN, Qualification,
      Contact_Number, SP_Photo, SP_Status, Caste, SHG_Member, Marital_Status,
      Salary, KYC_TYPE_ID, KYC_Code, Reference, Reference2, Agreement, Resigned,
      ResignedDate,delivery_status,allow_edit) 

    VALUES (" & dr("SP_ID") & ",'" & dr("SP_Name") & "','" & dr("Gender") & "','" 
      & dr("Date_Of_Birth") & "','" & dr("Date_Of_Join") & "'," 
      & dr("Branch_ID") & "," & dr("SP_Area_ID") & ",'" & dr("SP_Address1") 
      & "','" & dr("SP_Address2") & "','" & dr("SP_Address3") & "'," 
      & dr("PIN") & "," & dr("Qualification") & ",'" & dr("Contact_Number")
      & "'," & dr("SP_Photo") & ",'" & dr("SP_Status") & "','" & dr("Caste") 
      & "','" & dr("SHG_Member") & "','" & dr("Marital_Status") & "','" 
      & dr("Salary") & "'," & dr("KYC_TYPE_ID") & ",'" & dr("KYC_Code") 
      & "','" & dr("Reference") & "','" & dr("Reference2") & "','"
      & dr("Agreement") & "','" & dr("Resigned") & "','" & dr("ResignedDate") 
      & "','" & dr("delivery_status") & "','" & dr("allow_edit") & "','" 
      & Today.Date.ToString & "','" & Today.Date.ToString & "')")

Before inserting an image.

  1. Convert to byte array,i.e dim imgbyte as byte=datarow("Your Photo column")
  2. Then convert/build a Memory Stream and build image for the memory stream

  3. Now use the image which you have build and use it in insert query as shown below

    Dim img_b As Byte() = dr("SP_Photo")
    Dim img_stream As IO.MemoryStream img_stream = New IO.MemoryStream(img_b)
    Dim img As Image = Image.FromStream(img_stream)

    Dim cmd As New SqlCommand("update user_table_name set user_Photo=@image where user_ID=" & dr("SP_ID"), connstr)

    cmd.Parameters.Add("@image", SqlDbType.Image, img_b.Length).Value = img_b

    cmd.ExecuteNonQuery()

The error says it all: Byte() (i.e. an array of bytes) is a fundamentally different type from String and you cannot concatenate the two. How to solve this depends on what data these bytes contain and what you want to get from them. The Encoding.GetString method may help, if the bytes contain encoded text data.

More generally, the code you posted is beyond the pale. You cannot write code like this, it’s completely unreadable and hence worthless. Refactor it.
