When doing the insert directly on the bank, it adds perfectly. Could anyone help me?

Select all

insert into actweb.usuarios (matricula, nome, senha, nivel, maleta, email) values ('TESTE', 'Frederico', 'TESTE', 1, 7000, 'daerror@error.com.br');

Have I seen if the expression being mounted actually generates this SQL command?
This error usually occurs when Query is incomplete.
