Erro pós aula "Inserindo no banco"

Pareçe que tem um ";" (ponto e virgula) na sua query:

Caused by: android.database.sqlite.SQLiteException: near ";": syntax error (code 1): , while compiling: CREATE TABLE Alunos (id INTEGER PRIMARY KEY, nome TEXT NOT NULL, endereco TEXT, telefone TEXT, site TEXT, nota REAL;

Tenta retirar esse ponto-e-virgula.

Não resolveu :/

Assim está a classe

public class AlunoDAO extends SQLiteOpenHelper {

public AlunoDAO(Context context) { super(context, "Agenda", null, 1); }

@Override public void onCreate(SQLiteDatabase db) { String sql = "CREATE TABLE Alunos (id INTEGER PRIMARY KEY, nome TEXT NOT NULL, endereco TEXT, telefone TEXT, site TEXT, nota REAL"; db.execSQL(sql); }

@Override public void onUpgrade(SQLiteDatabase db, int oldVersion, int newVersion) { String sql = "DROP TABLE IF EXISTS Alunos"; db.execSQL(sql); onCreate(db); }

public void insere(Aluno aluno) { SQLiteDatabase db = getWritableDatabase();

ContentValues dados = new ContentValues(); dados.put("nome", aluno.getNome()); dados.put("endereco", aluno.getEndereco()); dados.put("telefone", aluno.getTelefone()); dados.put("site", aluno.getSite()); dados.put("nota", aluno.getNota());

db.insert("Alunos", null, dados); }

public List buscaAlunos() { String sql = "SELECT * FROM Alunos;"; SQLiteDatabase db = getReadableDatabase(); Cursor c = db.rawQuery(sql, null);

List alunos = new ArrayList(); while (c.moveToNext()) { Aluno aluno = new Aluno(); aluno.setId(c.getLong(c.getColumnIndex("id"))); aluno.setNome(c.getString(c.getColumnIndex("nome"))); aluno.setEndereco(c.getString(c.getColumnIndex("endereco"))); aluno.setTelefone(c.getString(c.getColumnIndex("telefone"))); aluno.setSite(c.getString(c.getColumnIndex("site"))); aluno.setNota(c.getDouble(c.getColumnIndex("nota")));

alunos.add(aluno);

} c.close();

return alunos;

} }

Mas agora e exception mudou,

parece que você tem um outro erro de sintaxe:

Caused by: android.database.sqlite.SQLiteException: near "REAL": syntax error (code 1): , while compiling: CREATE TABLE Alunos (id INTEGER PRIMARY KEY, nome TEXT NOT NULL, endereco TEXT, telefone TEXT, site TEXT, nota REAL

Não está faltando fechar o parenteses nessa query?

Não, ta tudo certinho, o erro aponta essa linha db.execSQL(sql);

Mas o metodo está todo certo @Override public void onCreate(SQLiteDatabase db) { String sql = "CREATE TABLE Alunos (id INTEGER PRIMARY KEY, nome TEXT NOT NULL, endereco TEXT, telefone TEXT, site TEXT, nota REAL"; db.execSQL(sql); }

Olá Caio,

A exception está bem precisa nesse caso, felizmente :)

Da uma olhada na sua query:

String sql = "CREATE TABLE Alunos (id INTEGER PRIMARY KEY, nome TEXT NOT NULL, endereco TEXT, telefone TEXT, site TEXT, nota REAL"

Ela deveria ser assim:

String sql = "CREATE TABLE Alunos (id INTEGER PRIMARY KEY, nome TEXT NOT NULL, endereco TEXT, telefone TEXT, site TEXT, nota REAL)"

Você abriu o parênteses depois do CREATE TABLE Alunos e depois não fechou, por isso disparou a exception de syntaxe incorreta.

Opa, agora sim!

Resolvido,

Obrigado!

Por favor, marque o tópico como solucionado :)
