Galera tou fazendo uma pesquisa em uma jtable mas na hora que eu clico no botão naum recebo o resultado…
con_Alunos.executeSQL("select * from "+tabela+" where Nome like'%"+CPPESQUISAR.getText());
preencher_table();
na hora q eu clico no botão quero q ele retorne o resultado na tabela me ajudem…
Onde vc guarda o resultset desse executeSql?
E não seria bom postar o método preencher_table()? Não dá para adivinhar o que você faz lá.

ai toda minha classe..
Tem um select ali dentro do método preencher_table().
Ele está sobrescrevendo seu filtro.
Dica… não use o DefaultTableModel e crie classes de negócio para seus dados. O seu código está bastante bagunçado.
