Delphi MSQL2012?

Question

Delphi

There is a database and tables inside MSSQL 2012

spoiler

The DB normally communicates, the data shows, the data adds in tables where there are no connected keys.
But no data is added to the TAB 1 table, the input data types are the same, here is the code

...
DataModule2.ADOQuery1.Append;
DataModule2.ADOQuery1.FieldByName('id_k1').AsInteger := 0;
DataModule2.ADOQuery1.FieldByName('id_k2).AsInteger := 1;
DataModule2.ADOQuery1.Post;
DataModule2.ADOQuery1.Refresh;
...

A similar code only works for other non-connected tables. (Adds, removes)
I tried to remove the connection id_k1 with id TAB2, also the same error on the same line.
