这个错误通常出现在使用SQLite数据库时的SQL语法错误。在SQL语句中,逗号的使用可能有问题。以下是一些解决方法:
String createTableQuery = "CREATE TABLE myTable (column1 TEXT, column2 INTEGER);";
String insertQuery = "INSERT INTO myTable (column1, column2) VALUES ('value1', 2);";
String insertQuery = "INSERT INTO myTable (column1, column2) VALUES (?, ?);";
SQLiteStatement statement = db.compileStatement(insertQuery);
statement.bindString(1, "value1");
statement.bindLong(2, 2);
statement.execute();
public class MyDatabaseHelper extends SQLiteOpenHelper {
private static final String DATABASE_NAME = "myDatabase.db";
private static final int DATABASE_VERSION = 1;
public MyDatabaseHelper(Context context) {
super(context, DATABASE_NAME, null, DATABASE_VERSION);
}
@Override
public void onCreate(SQLiteDatabase db) {
String createTableQuery = "CREATE TABLE myTable (column1 TEXT, column2 INTEGER);";
db.execSQL(createTableQuery);
}
@Override
public void onUpgrade(SQLiteDatabase db, int oldVersion, int newVersion) {
// 如果需要更新数据库结构,可以在这里处理
}
}
