OK. Here's part of the code:
----------------------------------------------------

// qDireito = TIBOQuery with internal UpdateSQL

for iDireito := 1 to 10 do begin
with DM.qDireito do begin
Insert;
FieldByName('CODIGO_DIREITO').Value := iDireito;
FieldByName('ORDEM').Value := StrToFloat(aOrd[iDireito]);
FieldByName('NIVEL').Value := aNiv[iDireito];
FieldByName('DESCRICAO').Value := aDesc[iDireito];
Post;
end;
end;

----------------------------------------------------
Here's is the table definition:
----------------------------------------------------

CREATE TABLE L_DIREITO (
CODIGO_DIREITO DECIMAL(18,0) NOT NULL
, ORDEM DECIMAL(18,0)
, NIVEL VARCHAR(2)
, DESCRICAO VARCHAR(100)
, NOME_MODULO VARCHAR(100)
, CONSTRAINT PK_L_DIREITO PRIMARY KEY (CODIGO_DIREITO)
);
