Error delete rows on table

Hi, I have two tables , deleted records of the two tables , then tried to delete again in Table 1 , an error occurred ( could not get print) , and in Table 2 records erased, again show in Table 2. Everything was running on a SQL console ( NetBeans ) and auto commit on. -- Luciano Sasso Vieira Data Scientist & Solutions Architect luciano@gsgroup.com.br http://www.gsgroup.com.br | tel: 17 3353-0833 | cel: 17 99706-9335 www.gsgroup.com.br http://www.gsgroup.com.br --- Este email foi escaneado pelo Avast antivírus. https://www.avast.com/antivirus
