Correlated query

Posted: 23 Jun 2013 06:48 PM PDT

hi this topic is related with correlated query my query is related with " Write a select command using a corelated subquery that selects the names and numbers of all customers with ratings equal to the maximum for their city."for this i triedSELECT abc.`CNAME`,abc.`RATING`FROM customers AS abcWHERE abc.`RATING`= (SELECT MAX(RATING) FROM customers WHERE ccity=abc.`CCITY` );which is working fine but later i triedSELECT cname,rating FROM customersWHERE rating= (SELECT MAX(RATING) FROM customers AS abc WHERE abc.`CCITY`=ccity );which gives me different resultmy question is what is difference between these two queries ? how they are executed exactly ? why they are showing different results

Pushing around large volumes of data

Posted: 23 Jun 2013 02:00 AM PDT

I have a recurring theme problem I'm trying to help solve where I work. We take a lot of historical line item transactional data and move it through various phases within SQL: Raw (unedited), Staging (for customer review), Production (after approval of staging).While the data is large in volume, we're not talking about Google or Twitter volumes of data. I'm talking about millions of rows of charge detail history for medical software.What I'm trying to best understand is the way to get things from point A to B with the minimal time and effort involved. Part of the issue is transactionally (volume of executions simultaneously running on the same server) and part of it is syntax (am I writing these movements most efficiently).What I'd love is some overall help to understand where I might be gaining more efficiencies in some of the basics. An example I'm working through this weekend is the following:Part of this detail history involves first cross checking field lengths, etc, to ensure accuracy before moving information into staging. One of the final steps for me is to concatenate three fields into the final patient account number on all the detail line items in history. When I first wrote the statement, it literally looked like the following:update temp_raw_chargedetailset Encounternumber = Field1+Field2+Field3One of my coworkers (former DBA/SQL guru) rewrote it quickly for me to the following recently:Set RowCount 100000update temp_raw_chargedetailset Encounternumber = Field1+Field2+Field3Where Encounternumber is NullWhile @@ROWCOUNT>0Begin update temp_raw_chargedetail set Encounternumber = Field1+Field2+Field3 Where Encounternumber is NullEndSet RowCount 0In initial tests, it is running quicker overall, but just this latter statement alone has been running on a 27 million record set of rows since 2 pm on Friday afternoon and here it is 10 am on Sunday. There is nothing else running on this server right now other than select statements I've been running to see where other databases/accounts stand. I just have a feeling something else could be done to mitigate some of this timing as it feels like I'm waiting a ridiculous amount of time for something that would seem somewhat superficial to complete processing.Any initial thoughts? I'm happy to provide additional details to start narrowing down how I could be thinking things through more efficiently. Thanks!

Join SQL Query help - Really stuck bad

Posted: 22 Jun 2013 07:15 PM PDT

I am in need of functionality for getting the Country name from the IP.I have to show the country in front of every unique visitor I have on my site. (Previously, I asked a question regarding a similar approach, but I changed it now.)The output I expect would be something as follows:-[quote] Country Visited | No. of Times _______________________________ United States | 482 Korea | 213 Pakistan | 123 ....[/quote]The output is showing that 482 Unique visitors have come from US, 213 from Korea, and so on.To achieve this, I divided this task into two part, first getting all the IPs of the Unique user and the second part is to search two tables with country/IP information to get the country.We then aggregate data based on the top output table shown. I am going to show the queries I wrote for each part. Below, I have shown the Structure and Sample Data of the tables used.First Part - Getting Unique Visitors on my site------------------------------------------------[quote] SELECT a.uid, a.hostname, COUNT( * ) AS times FROM login_activity a WHERE a.uid =83 GROUP BY a.hostname ORDER BY times[/quote]This shows the output as below. It means that the USer with ID 83 has 80 unique visits to the site.:-[quote] uid | hostname | times ------------------------------------- 83 | 157.191.122.36 | 80[/quote]This is wrong as I should be getting the no. of hits for each IP. But somehow I am unable to do so.Second Part - Finding the country based on IP---------------------------------------------[quote] SELECT cc, cn FROM ip NATURAL JOIN cc WHERE INET_ATON( "157.191.122.36" ) BETWEEN START AND END[/quote] This gives me the output as:- [quote] cc | cn -------- US | United States[/quote]This is correct, as it's giving me the correct Country based on the IP provided.With the help of these three tables and two queries I've shown on top, I need to show the following result:-[quote] Country Visited | No. of Times _______________________________ United States | 482 Korea | 213 Pakistan | 123 ....[/quote]I will be very thankful if you can help me in any way ...Appendix (Structure and Data of the Tables)-------------------------------------------**login_activity**---(Structure)[quote] CREATE TABLE IF NOT EXISTS `mslop_login_activity` ( `aid` int(10) unsigned NOT NULL AUTO_INCREMENT COMMENT 'The primary identifier for an activity (session).', `uid` int(10) unsigned NOT NULL DEFAULT '0' COMMENT 'The mslop_users.uid corresponding to a session, or 0 for anonymous user.', `host_user_agent` varchar(256) NOT NULL DEFAULT '' COMMENT '$_SERVER["HOST_USER_AGENT"] string. This can be used with get_browser() in PHP.', `hostname` varchar(128) NOT NULL DEFAULT '' COMMENT 'The IP address that was used for this session.', `timestamp` int(11) NOT NULL DEFAULT '0' COMMENT 'The UNIX timestamp when the session was started.', PRIMARY KEY (`aid`), KEY `aid` (`aid`), KEY `uid` (`uid`), KEY `timestamp` (`timestamp`) );[/quote](Data)[quote] INSERT INTO `mslop_login_activity` (`aid`, `uid`, `host_user_agent`, `hostname`, `timestamp`) VALUES (1, 3, 'Mozilla/5.0 (Macintosh;
