E as formas de utilização:

var result1 = window.ExecFetchXML('account', 'accountid, name', 'name', 'like', '%TESTE%', null, null, null, null);
alert(result1[0].accountid);
alert(result1[0].name);


/*
- Ordenado por [name];
- Ascendente [true];
- Retorna 2 páginas, com 10 clientes por página.
*/
var result2 = window.ExecFetchXML('account', 'accountid, name', 'name', 'eq', 'TESTE', 'name', 'true', 2, 10);

/*
- Busca por vários campos (name like '%TESTE%' e cnpj='12345678900');
*/
var result3 = window.ExecFetchXML('account', 'accountid, name', 'name,cnpj', 'like,eq', '%TESTE%,12345678900', null, null, null, null);
