Hello,

To insert NULL to a Blob field, you can use the following code:

Code: Select all

  UniTable1.Open;
  UniTable1.InsertRecord([1, null]); 
// or UniTable1.InsertRecord([1]); 
// or UniTable1.InsertRecord([1, nil]);
  If UniTable1.Fields[1].IsBlob then
    if UniTable1.Fields[1].IsNull then
      ShowMessage('Field is Null');
