Review on 'Sony Xperia Z' smartphone & design of 'Sony Xperia Z series'.

I have purchase 'Sony Xperia Z' on 17th September 2014, so I am sharing my experience and observation with you which are may be limited but different and from my perspective, (It may be also relevant for new Sony Xperia Z series e.g. Z2, Z3 as their body shape is exactly the same) for clarity in three headings:

Vantages:

1- Hardly hangs in any of the operations

2- Good provided ringtones

3- Wow, Camera quality, as always with Sony mobiles, both front and rare cameras are amazing

4- Itself ask to update latest Android

5- Fast processing even with high definition games

6- Good memory space and you can add microSD cards as well

7- Great battery life, play games on and on.......best among the phones I used and heard of


Minuses:

1- Speakers are not that powerful (same issue as my old Xperia Sola phone)

2- Location of the speaker is not suitable for people who hold the phone on his right hand, hand covers it & also when you play games and hold it horizontally, finger also covers it

3- Very soon & easily gets really heat-up, if you have not used any other waterproof phone, then especially at first it surprises & annoys you

4- When you set Alarm, first tap 'Set' but does not set the alarm, then on the next window you have to tap 'Done' as well. (New issue introduced, as it was not there with my old Xperia Sola)
.Suggestions to introduce in your mobile:

1- Wireless FM radio should now be introduce, even Pakistani 'QMobile' phones has wireless FM radio system

2- Dual speakers on different positions should be introduce like 'OnePlus One' phones or something to have that great music effect that dual speakers produced

Conclusion:

All in all a very good mobile for those who wants to purchase a good & latest Android mobile, one year ago it used to be the flagship mobile for Sony but still good enough to have as an excellent mobile

The AND operator displays a record if both the first condition and the second condition is true.

1-Select *from TABLEguirole where institutionid = '0002' AND role_id = 'full access';
2-SELECT CUSTOMERID

OR (customerid <  8 AND customerid > 6)
*-*-* IN *-*-*
SELECT *
FROM TABLECUSTCHANNELACCT
WHERE Channel_ID IN ('0007', '9999')
Multiple values in a WHERE clause; Used for equals to 0007 OR 9999
Gives exactly the value of the returned values we want to see.
The ‘In’ has to be inside the Where clause (it's not an order statement, is a select statement).

*HAVING clause was added to SQL because the WHERE keyword could not be used with aggregate functions.
*-*-* Alias, without As & JOINS *-*-*
                                                                                (Table alias)
1-      SELECT CHANNEL_ID, IS_DEFAULT from TABLEcustchannelacct ImTbAlias WHERE ImTbAlias.IS_DEFAULT = 1;

2-      SELECT CHANNEL_ID, IS_DEFAULT from TABLEcustchannelacct ImTbAlias WHERE IS_DEFAULT = 1;

(This will also run even without table alias before the column as there is no other table’s column which has the same name)

                                                                                (Column alias)
3-      Select channel_id ImClAlias from TABLEcustchannelacct;

2- Select * from TABLEguiuserrole where user_id='arbab';
3-SELECT * from TABLEregioninstitution where regionid='1900';

*-*-*-* Inner Joins (Implicit) *-*-*-* Equi-join
1-Select A1.Account_type,A1.Title, A2.Channel_id,A2.Account_type
from TABLEaccount A1, TABLEcustchannelacct A2
where A1.Account_type = A2.Account_type;
2-Select a1.CUSTOMERID, b1.customer_id

*-*-*-* Inner Joins (Implicit) with group by*-*-*-*
Select A1.TITLE (You may write Column alias here), SUM (A2.Account_ID) (You may write Column alias here)
from TABLEaccount A1, TABLEcustchannelacct A2
where a1.account_type = a2.account_type
group by a1.TITLE


*-*-*-* Outer Joins *-*-*-*
Outer join. With an outer join, you get all the records from one table and only those records from the other table that have matching values from the first table.
        *-*-*-*-* Concatenation *-*-*-*-*
1-Select concat (RELATIONSHIP_ID,TRAN_PERM)
from TABLEcustchannelacct
where account_type = '20';
(Note: The Oracle CONCAT() function only allows two arguments -- only two strings can be put together at a time using this function. However, it is possible to concatenate more than two strings at a time in Oracle using '||'.)
2-Select RELATIONSHIP_ID || ' ' || ACCOUNT_TYPE || ' ' || TRAN_PERM
from TABLECUSTCHANNELACCT
where account_type = '20';
*-*-*-*-* Subquery *-*-*-*-*
You know account_id but not the Title of the account,
Select Title from TABLEaccount where ACCOUNT_ID  in (select ACCOUNT_ID
from TABLEcustchannelacct
where ACCOUNT_ID like '477900783901%')
Ans. Imran Ahmed

Select Title,account_id from TABLEaccount where ACCOUNT_ID  in (select ACCOUNT_ID

4- SELECT SUBSTR('ABCDEFGhijklmno',-5,6) "Substring" -- Oracle counts backward from the end

5- Select * from TABLEcustchannelacct

2-Select length (RELATIONSHIP_ID) from TABLEcustchannelacct;

Both RTRIM and Length functions:
3-SELECT RTRIM(Account_id) || ' -- '|| length (RTRIM(Account_id)), length (Account_id)  from TABLEACCOUNT;
4-select log_feedback_id from TABLEimplogcustomer where Trim(cnic) like '%33100288099991%'

1-Alter table arbab
ADD CONSTRAINT Con_Name CHECK(GENDER='Male' OR GENDER='Female')
2-(Better query): What if you have to check the values in the column in a lsit of 10 or more values. How many times you will write OR OR OR ....?
That is the reason the values are check with IN (.,.,...) operator.
Alter table arbab
add constraint ck_abc
check (gender in ('MALE', 'FEMALE'));
Insert into arbab values ('abc','34343','99','');
Insert into arbab values ('abc','34343','99','Male');
Note: Insert value only work for either Male or Female or it enters a null.
