Question

我是Android编程的新手我正在尝试将一些数据添加到SqLite数据库中我在数据库中添加了一个名称和一个数字，但是我收到了语法错误我检查了很多网站，但我几乎没有发现任何语法错误如果有人能给予任何帮助，我将感激不尽。

这是我的代码：

@Override
    public void onCreate(SQLiteDatabase db) 
{
        String tablecreate = "create table " + tableName + " ( " + ID
                + " INTEGER PRIMARY KEY AUTOINCREMENT, " + NAME + " TEXT,"
                + NUMBER + " TEXT )";

        db.execSQL(tablecreate);
    }

public void addContact(String name, String num) {
        SQLiteDatabase database = this.getWritableDatabase();
        ContentValues cv = new ContentValues();
        cv.put(NAME, name);
        cv.put(NUMBER, num);
        database.insert(tableName, null, cv);
        database.close();
    }

这就是日志猫所说的：

Answer 1

您需要用方括号括住phone number 像这样[phone number]

在您的CREATE TABLE中以及您引用此字段的任何位置执行此操作。

或者，如果您始终使用名为NUMBER的字符串变量，请在变量定义中执行一次：

String NUMBER = "[phone number]";
