比如说,我们创建了一个表格:

create table notes (_id integer primary key autoincrement, created_date date)

要插入记录,我会使用

ContentValues initialValues = new ContentValues(); 
initialValues.put("date_created", "");
long rowId = mDb.insert(DATABASE_TABLE, null, initialValues);

但是如何将date_created列设置为now？为了说清楚,

initialValues.put("date_created", "datetime('now')");

不是正确的解决方案.它只是将列设置为"datetime('now')"文本.

任何人都可以告诉我这是什么.我在数据库中添加数据时出现此错误.它只发生在一个特定的行上.我试着通过互联网找到答案或理由.但是徒劳无功 截图

public void FunSetVisitorDetails(String strResult) {
    Log.d(TAG, "Get Visitor Details started.");
    if (!strResult.equalsIgnoreCase("NA") && !strResult.equalsIgnoreCase("NI")) {
        SQLiteDatabase database = getWritableDatabase();
        database.delete("TBL_VISITOR_MASTER", null, null);
            String[] strResultData = strResult.split("#");
            for (int index = 0; index < strResultData.length; index++) {
                String[] strRowData = strResultData[index].split(",");
                ContentValues values = new ContentValues();
                values.put("VISITORID", strRowData[0]);
                values.put("MEMBERID", strRowData[1]);
                values.put("TEAMID", strRowData[2]);
                values.put("CATEGORY", strRowData[3]);
                values.put("NAME", strRowData[4]);
                values.put("COMPNAME", strRowData[5]);
                values.put("SPECIALIZED1", strRowData[6]);
                values.put("SPECIALIZED2", strRowData[7]);
                values.put("SPECIALIZED3", strRowData[8]);
                values.put("SPECIALIZED4", strRowData[9]);
                values.put("SPECIALIZED5", strRowData[10]);
                values.put("CLIENT1", strRowData[11]);
                values.put("CLIENT2", strRowData[12]);
                values.put("CLIENT3", strRowData[13]);
                values.put("CLIENT4", strRowData[14]);
                values.put("CLIENT5", strRowData[15]);
                values.put("ASK", …

我正在尝试将数据插入 SQLite 数据库，为此我编写了一个简单的方法来插入我从 API 获取的数据，如下所示：

public static ContentValues gameInfoToContentValues(@NonNull GameInfoList game) {

        ContentValues values = new ContentValues();

        values.put(GameEntry.COLUMN_GAME_ID, game.id());
        values.put(GameEntry.COLUMN_GAME_ALIASES, game.aliases());
        values.put(GameEntry.COLUMN_GAME_API_DETAIL_URL, game.api_detail_url());
        values.put(GameEntry.COLUMN_GAME_DATE_ADDED, game.date_added());
        values.put(GameEntry.COLUMN_GAME_DATE_LAST_UPDATED, game.date_last_updated());
        values.put(GameEntry.COLUMN_GAME_SMALL_IMAGE, game.image().small_url());
        values.put(GameEntry.COLUMN_GAME_MEDIUM_IMAGE, game.image().medium_url());
        values.put(GameEntry.COLUMN_GAME_HD_IMAGE, game.image().super_url());
        values.put(GameEntry.COLUMN_GAME_NAME, game.name());
        values.put(GameEntry.COLUMN_GAME_ORIGINAL_RELEASE_DATE, game.original_game_rating());

        return values;
    }

我得到最后

game.original_game_rating();

这是正确的，因为它是一个对象列表。

我在方法中作为参数传递的名为“GameInfoList”的对象类如下所示：

public abstract long id();

@Nullable
public abstract String aliases();

@Nullable
public abstract String api_detail_url();

@Nullable
public abstract String date_added();

@Nullable
public abstract String date_last_updated();

@Nullable
public abstract GameImages image();

@Nullable
public abstract String name();

@Nullable
public …

我更新我想用搜索corrent POS机inspectionid，activityid，subactivityid但调用更新状态换货即时得到这个error.can有人帮助的时候。

public int updateSubActivityActivityComment(String comment, int rating, int subActivityId, int activityId, int inspectionId){
    SQLiteDatabase db = this.getWritableDatabase();
    ContentValues contentValues = new ContentValues();

    contentValues.put(KEY_RATING, rating);
    contentValues.put(KEY_COMMENT, comment);

    return db.updateWithOnConflict(TABLE_INSPECTION, contentValues,KEY_SUB_ACTIVITY_ID+ " = ? "+subActivityId+" AND "+KEY_INSPECTION_ID + " = ? "+inspectionId +" AND "+KEY_ACTIVITY_ID +" = ? "+activityId,new String[]{String.valueOf(subActivityId)} ,SQLiteDatabase.CONFLICT_IGNORE);
}
