Previous Row Comparison
I have a table in this format:
Column A | Column B
1 | 2
1 | 3
1 | 4
2 | 5
.....
.....
What I want to do is something like this:
If in Column A there is a change in the number i.e. from the above table there were many 1s which transitioned into a 2. I want to record this change. I want to extract these two rows into another table. How can I make this possible?

Select Previous And Next Id After Id=# ?
For a gallery I'm trying to query for a picture by its id and also get some images before and after that id (according to current sort) are there references like DOM previousNode or stuff like that to use in the WHERE statement? Or how could I do this? Currently I have: ($picId is a php variable) '(SELECT id, picUri, picUriSmall FROM pictures WHERE id < '.$picId.' ORDER BY id DESC LIMIT 2) UNION (SELECT id, picUri, picUriSmall FROM pictures WHERE id = '.$picId.') UNION (SELECT id, picUri, picUriSmall FROM pictures WHERE id > '.$picId.' LIMIT 2)' This works but doesn't seem to be the best way. I want to be able to have it working for other sorts than by id. And the two first images gotten by this query will be in reversed order (can be fixed in php). Is there a way to ask for my picIDs position in a query and then use another query to make the LIMIT 10,14 if my image was in position 12?
Paging With Only Next/previous
I'm running PHP + MySQL (innodb) and in some pages, the paging is slowing down the system a lot. Now I've seen on some sites that have paging implemented in an interesting way. They only let you go forwards and backwards one page at a time, and some don't even tell you how many results there are. For instance if you look at google search results, they only says "about XXX results". Plus they never actually let you jump to the last page. I'm thinking of implementing my system this way in certain pages as well, to cut down on the load times. However, I'm exactly sure how that cuts down the load. Can someone shed some light on this?
Previous To Last With A Certain WHERE Condition
How do i fetch the previous row record with the same WHERE when the last record has only a lately date. for example field CConsorcio CRubro ImporteA FechaA 1 105 1000 2006-05-10 2 110 30 2006-05-12 5 105 300 2006-05-13 4 104 600 2006-05-14 2 103 800 2006-05-15 the WHERE CConsorcio=2 the last record: 2,103,800,2006-05-15 and i want to select the row: 2,110,30,2006-05-12
Using Data From Previous Row
I only want to select the current row if a field in the previous row is not null. Is it possible to write such a query?
Previous Record
I need to get a previous record from database - i need to retrieve records which differs from the previous one about 5s example: select eventDate,previousEventDate,eventDate-previousEventDate as delta from events having delta<5 order by eventDate; eventDate is normal column from table previousEventDate is an "alias" for the previous date ... how can I write it in SQL? Please help. I can use SELECT as subquery, but it would be probably really slow, the table will have 100000s maybe milions of records soon.
Get Next And Previous Records
Our website has a portfolio database which uses a column entitled 'list_order' to set the order of how we want the projects to display in a list. Each project has a link to click into it to see the full details of the project. Inside this details page we would like to add a View Previous Project and View Next Project link which would allow the user to navigate through our projects. The problem is that we are using an order set by 'list_order' and not an auto incremented column. How would I setup the Query to grab the previous and next rows no matter which project the user clicked on? For example, our database has these records: id - list_order 102 - 100 89 - 200 7 - 250 30 - 300 97 - 400 20 - 500 62 - 600 88 - 650 103 - 700 85 - 800 112 - 900 95 - 1000 So, if someone clicked into id 97, we'd need a query that would grab id numbers 30 and 20 for the previous and next id to create the links.
ID Of Previous Insert
Im thinking i need a transaction here. I want to insert a record into a table, which has an autoincrement field as the primary id. Then use this id to insert into another table. In the time between the first insert and then getting the id, couldnt there possibly be another user that causes an insert and hence the id the first user gets back isnt correct ?transactions to the rescue ?
Subtract Previous Value.
I'm trying to get one column of numbers to subtract from another column and to keep a running total. Column A is a dollar amount from an invoice. Column B starts out with an opening amount ($10,000) and I want to have Column A to subtract from that. Code: COLUMN A--------COLUMN B $0.00 $10,000 $1000 $9,000 $500 $8,500 $2000 $6,500
Get Previous And Next ID Of Current Record
I want do create a "Previous" and a "Next" link, all I have is the ID of the current record. Is there a good way to get the previous and next id of a record with a single SQL Query? example: ID's: 4,10,7,9,13 I open my page and show all details from the record with the ID 7, now I want to create the links and I need the previous and the next ID, 10 and 9. I could make a query that returns only the ID's and loop through the recordset till i have my ID's but that's such an ugly solution, not to mention the performance issues.
Phase Previous And Next Record
I want do create a "Previous" and a "Next" link, all I have is the ID of the current record.

Previous And Next Record Delimma
I have a main page that has a query to get all my clients in alphabetical order. "SELECT * FROM clients ORDER BY cname ASC" This obviously mixes up their IDs. So when I click on a client's name "Goofy" (id = 6), I need the next client "Mickey Mouse" (id = 2), and "Donald Duck" (id = 9) to be the previous client. And I would prefer this to happen on the same page where it displays my client's details rather than have to put those vars in the URL. To get my client, it's simply: $client = $_GET['c']; "SELECT * FROM clients WHERE clientid = '".$client."'"
Getting Next, Previous Record After INSERT
When I insert a record in a given index order I want to be able to traverse to the previous or next record of that index order, before or after the one I inserted. So for example if I insert a record with an address of "20 Heather Court" using an address index order, I want to be able to push a Next button (on a Web HTML form) to go to the record corresponding to "21 Heather Court" or, if I press the Previous button I I want to be able to go the record corresponding to "19 Heather Court". Assuming of course that both the Next and Previous records exist before I insert "20 Heather Court". If I change the index order to customer first name and insert a new record for a customer named "Harry" I then want to be able to push the Next button and see the record for a customer named "Jan" or if I push the Previous button I likewise want to pull up the record for a customer named "Garry". Assuming that the records for Jan and Garry already existed before I inserted the one for Harry and that they became the Next and Previous records with respect to Harry's after the insertion. Using an auto increment field does no good because every time I change the index order any kind of sequential relationship between the values in the auto increment field gets totally messed up. I have also tried statements like " SELECT * FROM Customers WHERE Customer_ID <349 ORDER BY `Customer_ID` ASC LIMIT 0 , 1" without success if there are 10 records before the one with a Customer_ID of 349. A LIMIT of 0,1 will start at record 0 for only 1 record. I want to pull up the record immediately preceding the one with a Customer ID of 349. In short is there some way to tell which record is Next or Previous to one that I insert under a given index order?
Subtracting Current Row From Previous
I am trying to create a query that will subtract the current row of a column from the previous row, and if the value is negative, just return the value of the current column in the result column. For example, if I had the table below, here are the results I would like to see: Key value REQUIRED RESULT 1 12 12 2 21 9 3 3 3 4 1 1 5 67 66 .
Previous Version Coding
I am trying to load some sql into myphpadmin and whilst I believe I have a later version of 5.0 which is causing the error (as this coding is apparently up to version 5.0), can someone suggest how I go about finding the coding to use with my version? Here are some of the errors: CODESET SQL_MODE = "NO_AUTO_VALUE_ON_ZERO"
Determine Previous Month
basically I need to display a list of "unpaid" statements for the previous Month, no matter what day the search/request is made on. I know MySQL has the DATE_SUB function where I can subtract 1 Month from the current date, but will that subtract the date exactly 1 month to the day ? Or will it simply give me the Month as I need ? What happens if the search takes place on the 31st of a month (for example: July), yet the previous month only has 30 days (June). Will it roll back to the previous month correctly or think that the date is 31st June or try to roll back further until it finds another month which has 31 days ?
Previous Versions Of MySQL With XAMMP
I've downloaded XAMPP for Linux 1.5.1 for use on Fedora Core 4. I notice it only has the latest version of MySQL on it. I'm working on two web sites (for different clients) and they are hosted on different shared Linux hosting servers (with PHP), each with different versions of MySQL available, i.e: MySQL 4.0.25-standard MySQL 3.23.52 Is it possible for me to use older versions of MySQL with XAMPP? Could I just turn off MySQL in XAMMP and just run and older version of MySQL independently of XAMMP? If I can then how would I install multiple versions of MySQL in Fedora Core 4?
Getting Data Entered In The Previous Week

Get Previous And Next Records Relative To An Index Record
Suppose I have a table "product" with fields id,name,price. I want to get a resultset of previous and current and next record when the resultset is sorted by id and id=10. The table data is shown in the following: id Name Price 1 : : 5 : :<--------------previous record 10 : :<--------------id=10 12 : :<--------------next record 14 : : How do I write the sql statement if I do not know 5 and 12 are the previous and next id respectively?
How To Insert New Records Based On Previous Record Values?
I have TABLE: year value It has for example, year, code, vlaue 2007, 33, 4883 2006, 33, 4883 2007, 32, 4883 2006, 32, 4883 2008, 31, 4883 2007, 31, 4883 2006, 31, 4883 I want to insert new records for for 2008 for all codes that do not already have a record for 2008 and increase the value for the 2008 record by 3%. My several attempts have led to this but which does not work. UPDATE TABLE a SET a.value = b.value * 1.05 WHERE b.year = 2007 AND code NOT IN (SELECT code FROM TABLE b WHERE year =2008 AND value !=0)
Update Query Fails In Previous MySQL Version
The following query runs fine on my development server (v4.0.17): "update user inner join events on user.username = events.username set user.LastMessageDate = '$current_time' where events.text_sent=0 and events.to_mobile >0 and events.GMT_event_send_time<='$send_time'" but fails on my production server running v3.23.56. Anyone any ideas why it doesn't run and what I need to do to fix it?
Md5 Comparison
UPDATE admin_users SET password = md5(?') WHERE id = 1; SELECT password = md5(?') FROM admin_users WHERE id = 1; The result of the last query is "0", which means the values don't match. How can that be? What am I missing? The hashes look just the same when I echo them. Is it a data type problem? EDIT: I should mention the m5 password hash is stored in a binary(64) column.
Comparison In Db.
Don't know if it's even do-able in MySQL but I kinda think it is. lets make an example table over a log. day - action 1 ---- foo 1 ---- bar 2 ---- foo 2 ---- foo 2 ---- bar 2 ---- bar 2 ---- foo Now I want, with one query, most of all, select the increase in percent and the name of the action that has increased the most from day one to day two. If this isn't possible I would like to select the name, the amount for the action on day one and the increase of the top increaser.
Dates Comparison??
I'm trying to find people from my db based on a given min_date and max_date using: SELECT . . . WHERE birthdate BETWEEN '".$dd_min_age."' AND '".$dd_max_age."' but if a range is specified there are no results returned. If I choose though the same date for min and max then I get the corresponding results.
Sql Comparison Tools
We've got a bunch of fairly long and complex sql statements that we need to compare between our dev and prd environments. The dev environment has been changed by a bunch of patches, while prd has been changed by an incompetent BA. Does anyone know of any tools that can help do this? Standard text/file comparison tools haven't been any help, so we're down to eyeballing them, which is both no fun and prone to error...
Comparison Query?
I have two tables in my database that collect membership/user info. How do I write a query to compare the two and have the query spit out the users that are on one but not the other?
Comparison Query
I have two tables, I have a company table and a client table. The fields in question are as follows Company.companyid Company.maincontactid Contact.contactid Due to bad design and bad data entry we have a bunch of companies with a contact number but no entry in the contact table. I want to run a query to dump a list of Company.companyid and Company.maincontactid where Company.maincontactid has no corrisponding Contact.contacid
Text Comparison
I'm having a problem with one query. My database has the following fields: id(int), time(int), and groupfield(enum - 5 possibilities). I want to select all the rows where the time is between let's say 12 and 24 and the group is specified by the user using a html drop list. The variable is named $group. Code:
String Comparison
I need to search a table for certain area codes. Because the office does not have a uniform way of entering phone numbers into the database, some are entered as (555)555-5555 and others as 555-555-5555. I have a select statement in which I want to return phone numbers beginning with a certain area code indepent of how the phone number was entered. I've tried the following: CODESELECT customers_telephone FROM customers WHERE customers_groups_id = 3 AND customers_telephone like '(310)%' OR customers_telephone like '310%'
String Comparison
I would like to search a column of strings for matches to a given prefix. Is there a way to use existing string comparison functions to do this? Specifically I'm looking for the number of leading characters identical to my (variable) search string: Example: looking for matches to prefix "Robb" SELECT names, some_functions(names, "Robb") AS m FROM etc, etc, etc... | names | m | | Roger | 2 | | Robert | 3 | | Roseanne | 2 | | Cary | 0 | | Randy | 1 | | Robby | 4 | | Allison | 0 | Return the highest value of m for which LEFT(names,m)=LEFT("Robb",m). I've been reading through the section on string comparison function, but can't find anything suitable. But perhaps there is some combination of funtions you could use?
String Comparison
When i update a table i am carrying out a check to see if that entry already exists. This is ok when it is the same case but when it is different it allows it. select count( entityid ) as COUNTENTITIES from entities where code = '%1%' I have tried LIKE but that didn't work either What i am after is if there is a code 'c1' in database and someone tries 'C1' i want that to fail because 'c1' is already there. Is this possible?
Database Comparison
I am looking for some papers/information that compare relational databases such as oracle, mysql, sql server etc. I am particularly interested in their features such as locking mechanisms, integrity constraints, views... Anyone know where I can find the information?
Float Comparison
I'm writing a simple database with one table and a few fields that lists some books. One of the fields is an Unsigned Float field that lists the book's reading level. Then I have a PHP/web page front end that users can search for books listed in the database. Basically this is the probelm I'm having: If a user asks for all the books between the reading levels 3.0 and 3.3 -- MySQL returns every record that has a reading level of 3 up to and including all the books with a reading level of 3.3. However, if a user types in the form they want all the books between 3.0 and 3.2 -- MySQL returns all the 3.0 and 3.1 books, but returns none of the 3.2 level books. The code is a simple select query that ends up being: SELECT * FROM MyTable WHERE ReadingLevel >= 3 AND ReadingLevel <= 3.x
Date Comparison
I have date comparison problem with mysql... why doesn't the date get in the set? (2nd query returns empty set) mysql> select version(); +------------+ | version() | +------------+ | 4.0.20-log | +------------+ 1 row in set (0.00 sec) mysql> SELECT RecordID FROM Record WHERE DATE_ADD(PostDT,INTERVAL 11 HOUR) >= CAST('2005-3-13 00:00:00' AS datetime) AND DATE_ADD(PostDT,INTERVAL 11 HOUR) <= CAST('2005-3-13 23:59:59' AS datetime) ORDER BY PostDT DESC; Empty set (0.00 sec) mysql> select DATE_ADD(PostDT,INTERVAL 11 HOUR) FROM Record; +-----------------------------------+ | DATE_ADD(PostDT,INTERVAL 11 HOUR) | +-----------------------------------+ | 2005-03-13 12:00:00 | | 2005-05-27 21:53:30 | +-----------------------------------+ 2 rows in set (0.00 sec)
Date Comparison 2
I want to compare dates in sequential records (in mysql format YYYY-MM-DD) in a db. I have a loop to iterate through a set of records. In this loop, how can I refer to the previous record in the loop? As in: for ($i=0; $i <$num_results; i++) { $row = mysql_fetch_assoc($result); if ($row('thisDate') != the previous record's date) { do something } }
Date Comparison
In a php_mysql query the following variable: $ckDate = $year . "-" . $mo_sel . "-01"; produces a string in the format YYYY-MM-DD. The $year and $mo_sel variables have been posted from a form. The problem I am experiencing is that in trying to SELECT from a table by comparing the $ckDate variable to the arrDate field in the database, the search returns a result no matter what the comparision date is, as in: "select * from this_table where 'arrDate' >= '$ckDate'" No matter what the value of $ckDate, the query returns data. Does this variable have to be coerced in some manner?
DATE COMPARISON
I was wondering if there is a date function to get the older date between two dates?. Or smething that indicates me that one date is older than the other one.I know that I have the function YEAR,MONTH,DAY and I can use them, but I don't know if exists a function that can do the same.
Comparison Optimization
On to my problem. I'm running a query on a table with over 100,000 rows in it. Basically, my query is performing a "similar" check on books that people have logged in their "book list". It looks through the table and checks to see who has the most number of books similar to you. Here's the query: select count(a.mem_id) as numMatches,m.username,m.mem_id as memberID from book_list a LEFT JOIN book_list_members m ON a.mem_id=m.mem_id where a.book_id in(224,164,30,43,47,1,6,52,90,45,120,270,...,2442) GROUP BY a.mem_id ORDER BY numMatches DESC LIMIT 50 In the in() comparison, this can be anywhere from 1 integer to 1000 integers, it all depends on how many books a user has in their list. I've indexed "book_id", but unfortunately if there are more than say, 100 elements in the IN() comparison, the query takes anywhere from 1-2 seconds to execute. That's a long time when I have hundreds of users hitting a website and running that query. Is there a better way to do this? Is there a way I can "store" this query result somewhere, and only have it updated every couple hours (cached in other words, for immediate access).
Datetime Comparison
I have a query in a php page that goes something like this: SELECT * FROM posts WHERE post_time < '$php_var_date' LIMIT 0,1 I'm using this in a blog where I need the previous post's post date. php_var_date is an ISO 8601 formatted date. The post_time is of the data type datetime. While I don't get an error on execution of the query, it keeps returning the date EQUAL to php_var_date instead of the one previous to it. My question is, is this a MySQL glitch or is it something incorrectly set on the server?
Fake Date Comparison
Code: select * from tareas where STR_TO_DATE( fecha, '%d/%m/%Y' ) = STR_TO_DATE( 19/11/2007, '%d/%m/%Y' )' order by STR_TO_DATE( fecha, '%d/%m/%Y' ) DESC Yes, an operator wrong, but why ?
Date Comparison Problem
I have a website with a diary of events. I have just come across this problem: The diary is listed on the site month by month - you can click a month and events for that month will show up. Events have a from date and to date and can span across multiple months. This has all been working fine until I added an event running from december 06 to january 07 - it no longer showed up. Here is how my query looked: (using december 2006 as the selected page as an example) SELECT * FROM diary WHERE (MONTH(from_date) <= MONTH(��-12-01') AND MONTH(to_date) >= MONTH(��-12-01') AND YEAR(from_date) = YEAR(��-12-01')) OR (MONTH(from_date) <= MONTH(��-12-01') AND MONTH(to_date) >= MONTH(��-12-01') AND YEAR(to_date) = YEAR(��-12-01')) ORDER BY from_date, to_date Now looking back it is obvious that this will not work as it is looking for a match in the years. After some research and trial and error I have come up with the following query: SELECT * FROM diary WHERE (UNIX_TIMESTAMP(��-12-01') BETWEEN UNIX_TIMESTAMP(from_date) AND UNIX_TIMESTAMP(to_date)) ORDER BY from_date, to_date However this is still not working. This is really bugging me and any help will be greatly appreciated. Thanks!
How To Write Like Comparison In Procedures?
this sample procedure takes in an username, searches for number of entries matching the pattern of the username. delimiter $$ create procedure sampleDB.sampleProcedure( IN m_username varchar(30), OUT m_username_matched_count int ) deterministic begin if length(m_username) = 0 then set m_username = 'jason' #set temporary name if empty end if set m_username_matched = 0; #finds number of matches for the given username select count(*) into m_username_matched #store into the variable to be returned from sampleDB.sampleTable where userName like '%m_username%' #this is the statement that does not work# end$$
TIMESTAMP Operations & Comparison
I'm trying to write a query that will remove all entries older than 30 days, using MySQL 5. The date is stored as TIMESTAMP. I'm stumped on just how to express "30 days earlier than now". I'm familar with the NOW() function but don't know how to add/subtract dates. The query is otherwise very simple, something like DELETE FROM posts WHERE datecreated < [????]
