Android Question insert image in SQL DB ?

Paulsche · Dec 26, 2013

Hello,

I want to insert in my table an image
I have added in the DB field.

How should the following code (
ExecNonQuery)
when I image (BLOB)
would like to insert as the last field to save?

Have been very much sought, but found no example with multiple fields.

B4X:

    Dim InputStream1 As InputStream
    InputStream1                                            = File.OpenInput(File.DirDefaultExternal, "temp_klein.jpg")
    Dim OutputStream1 As OutputStream
    OutputStream1.InitializeToBytesArray(1000)
    File.Copy2(InputStream1, OutputStream1)
    Dim Buffer() As Byte                                                                                                                        'declares an empty array
    Buffer                                                        = OutputStream1.ToBytesArray


    If M_Artikel_aendern = False Then                                                                                                'Wenn Neuanlage gewählt wurde
        angehakt                                                = 0                                                                                        'Artikel nicht zur auswahl angehakt setzen
        SQLartikel.ExecNonQuery("INSERT INTO Artikel (datumticks,datum,name,kat,eht,preis,notiz,angehakt) values("&DateTime.Now&",'"&LBL05dat_Datum.Text&"','"&EDT05Name.Text&"','"&EDT05Kategorie.Text&"','"&EDT05Menge_EHT.Text&"','"&EDT05Preis.Text&"','"&EDT05Notiz.Text&"','"&angehakt&"')")

You should use ExecNonQuery2 instead.

See the blob example in he tutorial: http://www.b4x.com/android/forum/threads/sql-tutorial.6736/

B4X:

SQLartikel.ExecNonQuery2("INSERT INTO Artikel values("&DateTime.Now&",'"&LBL05dat_Datum.Text&"','"&EDT05Name.Text&"','"&EDT05Kategorie.Text&"','"&EDT05Menge_EHT.Text&"','"&EDT05Preis.Text&"','"&EDT05Notiz.Text&"','"&angehakt&"', ?)", Array As Object(Buffer))

Does not work so.
What is wrong ?

Thanks Erel, it works well, that in my line of code was the missing Primery Key with value NULL.

SQLartikel.ExecNonQuery2("INSERT INTO Artikel values(NULL,"&DateTime.Now&",'"&LBL05dat_Datum.Text&"','"&EDT05Name.Text&"','"&EDT05Kategorie.Text&"','"&EDT05Menge_EHT.Text&"','"&EDT05Preis.Text&"','"&EDT05Notiz.Text&"','"&angehakt&"', ?)", Array As Object(Buffer))
