MSSQL6.5 stored proc question

Hi there,

I am experiencing a problem using a SQL server 6.5 stored procedure in delphi 2.0. One of the input parameters for the stored procedure is of type text- ie a blob field- however, there is no way to secify this as the data type for the parameter using the parameters editor. If I specify it to have type string, then longer values assigned to the parameter become truncated after roughtly 255 characters. I have also tried to get around the problem using the Assingn method, but without success. Any help in this regard would be greatly appreciated.

Thanks.

Try to execute the stored proc in a TQuery.

TQuery.SQL:

  execute <stored proc> 'texttexttext'

Example:

  with AQuery do
  begin
    Active := false;
    SQL.Clear;
    SQL.Add('execute the_real_storedproc '''+AMemo.Text+'''');
    ExecSQL;   // when You except no result
//  Open;         when You expect a result table
  end;

You have to double all the hooks in the Memo, before you send it with the stored proc, because MSSQL works like pascal. A hook in the string represents the beginning or the end. Two hooks represents a single hook. :*)
