安卓 2.3.3

static String name = "Database";
static int version = 1;

SQLiteDatabase sqlDB;
Cursor c;


public Database(Context context) {
    super(context, name, null, version);
    // TODO Auto-generated constructor stub

    sqlDB = getWritableDatabase();

    }

    @Override
    public void onCreate(SQLiteDatabase sqlDB) {
        // TODO Auto-generated method stub


    sqlDB.execSQL("create table if not exists Operations(Command Text, Pos1 Text, " +
                "Pos2 Text, Pos3 Text, Pos4 Text, Pos5 Text, Pos6 Text, Pos7 Text, Pos8 Text, Pos9 Text, Pos10 Text)");


    }

public void insertData() {
        // TODO Auto-generated method stub

        String addQuery ="ADD, add, and, had, ad, anddd, anndd, null, null, null, null";

                sqlDB.execSQL("insert into Operations values("+ addQuery +")"); 
                     //Exception at the above line
}

共有 11 列。

我可以在数据库中插入 NULL 吗？如果是，我尝试将数据插入数据库的方式有什么问题吗？

这是我得到的错误:::

有人可以帮助我为什么我在语法上遇到这个错误吗？

Strings should be inclused in '' so change String addQuery ="ADD, add, and, had, ad, anddd, anndd, null, null, null, null";

to:

String addQuery ="'ADD', 'add', 'and', 'had', 'ad', 'anddd', 'anndd', null, null, null, null";

 //  Possible to Get Error 
    public void insertData() {
            // TODO Auto-generated method stub

            String addQuery ="ADD, add, and, had, ad, anddd, anndd, null, null, null, null";

                    sqlDB.execSQL("insert into Operations values("+ addQuery +")"); 
                         //Exception at the above line
    }

    use Like Below 

    public void insertData() {

    ContentValues cv=new ContentValues();
    cv.put("column1,value);
    cv.put("column2,value);
    cv.put("column3,value);
    cv.put("column4,value);
    cv.put("column5,value);
    cv.put("column7,value);
     database.insert(tabName, SINGLE_colName, cv);

    }

根据我的说法，您已经定义了一个具有 11 个值的字符串（addQuery），但它将其计为一个。我确定存在问题，这就是您遇到运行时错误的原因。

SQL 语法错误，请使用insert into test(aa,bb) values('ADD','BB') which aa 是您的字段名，'ADD' 是字符串
