This is my insert routine to create an entry into the table AGENTES with
identification, name and the photography. (105x128)

when i execute it i got :

"ERROR [42000] [Microsoft][ODBC SQL Server Driver][SQL Server]Must declare
the variable '@imgID'."



any idea?

thx in advance!




MemoryStream memoryStream = new MemoryStream();

byte[] imageBytes=null;

button1.Image.Save(memoryStream,System.Drawing.Imaging.ImageFormat.Gif);

imageBytes = memoryStream.ToArray();

memoryStream.Close();

OdbcCommand cmd = new OdbcCommand ("INSERT INTO AGENTES(ID,NAME,PHOTO)
VALUES (@imgID,@imgName,@imgPhoto )", conn );

OdbcParameter paramTitle = new OdbcParameter( "@imgID", OdbcType.Char,10 );

paramTitle.Value = tbID.Text;

cmd.Parameters.Add( paramTitle);

OdbcParameter paramData = new OdbcParameter( "@imgPhoto", OdbcType.Image );

paramData.Value = imageBytes;

cmd.Parameters.Add( paramData );

OdbcParameter paramType = new OdbcParameter( "@imgName",
OdbcType.VarChar,50 );

paramType.Value = tbName.Text;

cmd.Parameters.Add( paramType );

try

{

int numRowsAffected = cmd.ExecuteNonQuery();

}

catch (Exception ex)

{

string x="";

}
 
You are using Odbc for database access, Odbc uses the question mark "?" for parameter position, not @parameter

thx. but if i change the @ by ? i got the
"ERROR [42000] [Microsoft][ODBC SQL Server Driver][SQL Server]Must declare

what about using an OdbcCommandBuilder to generate you commands from the
insert ?
then if you do need to set the command yourself, you could at least at what
the command builder generated, that would gives you idea at least ! ...
