To read data from and write text data to a BLOB field, you need to use the InStreams and OutStreams objects as previously described.

The two methods in the following code read and write text data from and to a BLOB field defined in a custom table:

table 50120 MyBlobTable
{
    DataClassification = CustomerContent;   
    fields
    {
        field(1;ID; Integer)
        {
            DataClassification = CustomerContent;           
        }

        field(2; BlobField; Blob)
        {
            DataClassification = CustomerContent;
        }
    }
   
    keys
    {
        key(PK; ID)
        {
            Clustered = true;
        }
    }
   
    procedure SetBlobValue(value: Text)
    var
        outStr: OutStream;
    begin
        BlobField.CreateOutStream(outStr);
        outStr.WriteText(value);
    end;

    procedure GetBlobValue(value...
