Criei uma classe java chamada ‘detalhesescolares.java’ onde possuo o jframe abaixo:
fiz uma conexão com a classe e um banco de dados, criei uma rotina para inserir e atualizar no banco de dados, e ao clickar em criar/atualizar aparece a seguinte mensagem : java.sql.SQLSyntaxErrorException nao é uma coluna na tabela ou VTI “ROOT.DETALHESESCOLARES”
Banco de dados:
detalhesescolares.java:
