PhoneGap android の表は次のとおりです。

tx.executeSql( "CREATE TABLE IF NOT EXISTS user_prayers('id' INTEGER NOT NULL PRIMARY KEY AUTOINCREMENT UNIQUE,'prayer_id' TEXT ,'user_id' INTEGER,'date' DATETIME,'status' INTEGER)",[],successCB,エラーCB);

ループを使用して行を挿入します。

function insertInUserPrayerTable() {
                        db.transaction(function(tx)
                         {for(var i = 0;i<5;i++)
                        {checkedValueofCheckboxInsertArray.push('INSERT INTO user_prayers '

                             + '(prayer_id,user_id,date,status)'
                                + ' VALUES("'
                                + checkedValueofCheckbox[i]
                                + '","'
                                + window.localStorage
                                        .getItem("userid") + '","'
                                + $('#datepicker').val() + '","'
                                + statusofNamaz[i] + '");');

                console.log("array values:"+checkedValueofCheckboxInsertArray);
                        }
                         },errorCB,successCB);

                                                                [],

しかし、同じクエリがSQLフィドルで正常に機能している間、ステータスが返されません:

答えはsqlite からです: SELECT 句で条件付き OR / COALESCE を作成する方法はありますか?

SELECT CASE WHEN (TitleSP = '' OR TitleSP IS NULL)
            THEN COALESCE(TitleEN, '')
        WHEN (TitleEN = '' OR TitleEN IS NULL)
            THEN TitleSP
        ELSE (TitleSP || ' / ' || TitleEN)
   END AS Title,
