I'm using sql query as follow:

update myTable set d_1=current_date, d_mod = current_timestamp, zapos = :zapos, MyMemo = (MyMemo || :TextToAdd) where nr = :nr

:zapos(VARCHAR[15])='Odbiór osobisty'
:TextToAdd(VARCHAR[27])='Towar odebrał: XXXX'
:nr(VARCHAR[10])='24899/09'
-----

It raise my application error like this

Error:
Dynamic SQL Error
SQL error code = -303
arithmetic exception, numeric overflow, or string truncation
-----

The same query with same parametres pasted in the IBExpert working fine.

I'm using IBDAC 3.0.0.3 --> TIBCQuery
Database is Firebird 2.1
MyMemo field is Varchar(4000)

I can't understand, what is wrong. Can anyone help me?

Do You have correct charset ?

I belive Yes. Other queries like
update myTable set MyMemo='Yogi Bear' working wihout a problems.

Everythings happens in big application. There is many diferent queries setting free text's in many fields. I have no problem with charset.

Odbiór osobisty' string has special character but 'Yogi Bear'
does not so it works even with wrong charset.

"arithmetic exception, numeric overflow, or string truncation" error message usually indicates wrong charset or that you try to post too long string or a char to a numeric field.

This my delphi code:
tmp.SQL.text := 'update MyTable set MyMemo= :MyTextToAdd where nr=:nr';
tmp.ParamByName('MyTextToAdd').Text := 'ążśźć곥ŻŚŹĆĘŁóÓ';
tmp.ParamByName('nr').Text := '6650/09/H';
tmp.ExecSQL;

This is IBCSQLMonitor's log:

:MyTextToAdd(VARCHAR[16])='ążśźć곥ŻŚŹĆĘŁóÓ'

Has anyone any other idea?

Archer, you puted me to the right track. The problem was with zapos field. This field is varchar[1]. I forgot to trim text length.

My fault. Thank you!
