  • How can I forward a query string using htaccess?

    - by Eric
    I am using this, at present, to rewrite URLS: RewriteEngine on RewriteRule ^([^/?\.]+)$ /page.php?name=$1 [NC] So mysite.com/home gets rewritten to mysite.com/page.php?name=home How can I make it also rewrite mysite.com/home?param=value to mysite.com/page.php?name=home&param=value? Ideally, I'd like this to work for any name/value querystring pairs. Am I missing something obvious?

  • Any idea why this query always returns duplicate items?

    - by Kardo
    I want to get all Images not used by current ItemID. The this subquery but it also always returns duplicate Images: EDITED select Images.ImageID, Images.ItemStatus, Images.UserName, Images.Url, Image_Item.ItemID, Image_Item.ItemID from Images left join (select ImageID, ItemID, MAX(DateCreated) x from Image_Item where ItemID != '5a0077fe-cf86-434d-9f3b-7ff3030a1b6e' group by ImageID, ItemID having count(*) = 1) image_item on Images.imageid = image_item.imageid where ItemID is not null I guess the problem is with the subquery which I can't avoid duplicate rows: select ImageID, ItemID, MAX(DateCreated) x from Image_Item where ItemID != '5a0077fe-cf86-434d-9f3b-7ff3030a1b6e' group by ImageID, ItemID having count(*) = 1 Result: F2EECBDC-963D-42A7-90B1-4F82F89A64C7 0578AC61-3C32-4A1D-812C-60A09A661E71 F2EECBDC-963D-42A7-90B1-4F82F89A64C7 9A4EC913-5AD6-4F9E-AF6D-CF4455D81C10 42BC8B1A-7430-4915-9CDA-C907CBC76D6A CB298EB9-A105-4797-985E-A370013B684F 16371C34-B861-477C-9A7C-DEB27C8F333D 44E6349B-7EBF-4C7E-B3B0-1C6E2F19992C Table: Images ImageID uniqueidentifier UserName nvarchar(100) DateCreated smalldatetime Url nvarchar(250) ItemStatus char(1) Table: Image_Item ImageID uniqueidentifier ItemID uniqueidentifier UserName nvarchar(100) ItemStatus char(1) DateCreated smalldatetime Any kind help is highly appreciated.

  • How to get line count from variable (from MYSQL query)?

    - by Mint
    My problematic code: testMYSQL=`mysql -u $mysqlUser -p$mysqlPass -h $mysqlHost --skip-column-names --batch -D $mysqlDB -e "SELECT $select FROM $mysqlTable WHERE nameTXT='test';"` $testMYSQL now contains: test test test Then I do: TEST=$(echo $testMYSQL | wc -l) echo "$TEST" I would of thought that would work, but it doesn't, it returns 1 But if I put this into $testMYSQL: "test\ntest\ntest" it will say 3… Whats going on here? does MYSQL not use new lines? PS, I know I can use a for loop to loop though the lines then count up the lines that way, but I was hoping for a simpler solution like wc

  • SQL Server 15MM rows, simple COUNT query. 15+ seconds?

    - by john
    We took over a website from another company after a client decided to switch. We have a table that grows by about 25k records a day, and is currently at 15MM records. The table looks something like: id (PK, int, not null) member_id (int, not null) another_id (int, not null) date (datetime, not null) SELECT COUNT(id) FROM tbl can take up to 15 seconds. A simple inner join on 'another_id' takes over 30 seconds. I can't imagine why this is taking so long. Any advice? SQL Server 2005 Express

  • In ruby on rails, is it possible to do a sum query with group by using the find_each batching?

    - by BarryOg
    I'm loading data from my database and I'm doing a sum calculation with a group by. ElectricityReading.sum(:electricity_value, :group => "electricity_timestamp", :having => ["electricity_timestamp = '2010-02-14 23:30:00'"]) My data sets are extremely large, 100k upwards so I was wondering if its possible to use the find_each to batch this to help with memory overhead. I can write the batching manually use limit and offset I guess but I'd like to avoid that if the code already exists.

  • which sql query is more efficient: select count(*) or select ... where key>value?

    - by davka
    I need to periodically update a local cache with new additions to some DB table. The table rows contain an auto-increment sequential number (SN) field. The cache keeps this number too, so basically I just need to fetch all rows with SN larger than the highest I already have. SELECT * FROM table where SN > <max_cached_SN> However, the majority of the attempts will bring no data (I just need to make sure that I have an absolutely up-to-date local copy). So I wander if this will be more efficient: count = SELECT count(*) from table; if (count > <cache_size>) // fetch new rows as above I suppose that selecting by an indexed numeric field is quite efficient, so I wander whether using count has benefit. On the other hand, this test/update will be done quite frequently and by many clients, so there is a motivation to optimize it.

  • My tricky SQL Update query not working so well.

    - by Spooks
    I am trying to update a table in my database with another row from another table. I have two parameters one being the ID and another being the row number (as you can select which row you want from the GUI) this part of the code works fine, this returns one column of a single row. (select txtPageContent FROM (select *, Row_Number() OVER (ORDER BY ArchiveDate asc) as rowid from ARC_Content Where ContentID = @ContentID) as test Where rowid = @rowID) its just when i try to add the update/set it won't work. I am probably missing something update TBL_Content Set TBL_Content.txtPageContent = (select txtPageContent FROM (select *, Row_Number() OVER (ORDER BY ArchiveDate asc) as rowid from ARC_Content Where ContentID = @ContentID) as test Where rowid = @rowID) Thanks for the help! (i have tried top 1 with no avail)

  • Autohotkey to map F5 to Shift+Home and then F5 - eventually executing a single line query in sql server?

    - by puretechy
    Reading the syntax from autohotkey, I am trying to achieve this. But the first step of selecting the entire line is not working:- F5:: send {Shift Home} return I have tried few others too, but its not working. This is not sending Shift+Home combination on pressing F5 key. Please tell me what's wrong with this? Also if possible, what to do next?, as if I will write send {F5} I believe, it will recursively fire this script again and again..

  • How do i query to list out all commits by a user to a subversion repository?

    - by VDev
    The title pretty much sums up my question, I would like to find all commits I have ever done to the subversion repository. Not just commits in current snapshot. More importantly, I would like to organize the file lists by the SVN comment used while committing. Thank you Edit: I am thinking maybe a python or shell script that would parse the output of svn log | grep username to extract revisions and then pipes the output to svn log -r [revision numbers go here] Maybe some scripting gurus can help me out..

  • In a MySQL SELECT query, can I use my "AS column" in a WHERE specification?

    - by user556352
    In my database I calculate distance between nodes with: SELECT DISTINCT dest.name, AsText(orig.location), AsText(dest.location), round((glength(linestringfromwkb(linestring((orig.location), (dest.location)))))) as distance FROM nodes orig, nodes dest WHERE orig.name='GERP' I would like to add "and distance < dest.visibility" at the end, but am told that distance is an unknown column. Any insight very much appreciated.

  • How to tell the Session to throw the error query[NHibernate]?

    - by xandy
    I made a test class against the repository methods shown below: public void AddFile<TFileType>(TFileType FileToAdd) where TFileType : File { try { _session.Save(FileToAdd); _session.Flush(); } catch (Exception e) { if (e.InnerException.Message.Contains("Violation of UNIQUE KEY")) throw new ArgumentException("Unique Name must be unique"); else throw e; } } public void RemoveFile(File FileToRemove) { _session.Delete(FileToRemove); _session.Flush(); } And the test class: try { Data.File crashFile = new Data.File(); crashFile.UniqueName = "NonUniqueFileNameTest"; crashFile.Extension = ".abc"; repo.AddFile(crashFile); Assert.Fail(); } catch (Exception e) { Assert.IsInstanceOfType(e, typeof(ArgumentException)); } // Clean up the file Data.File removeFile = repo.GetFiles().Where(f => f.UniqueName == "NonUniqueFileNameTest").FirstOrDefault(); repo.RemoveFile(removeFile); The test fails. When I step in to trace the problem, I found out that when I do the _session.flush() right after _session.delete(), it throws the exception, and if I look at the sql it does, it is actually submitting a "INSERT INTO" statement, which is exactly the sql that cause UNIQUE CONSTRAINT error. I tried to encapsulate both in transaction but still same problem happens. Anyone know the reason?

  • MS SQL Server slows down over time?

    - by Dave Holland
    Have any of you experienced the following, and have you found a solution: A large part of our website's back-end is MS SQL Server 2005. Every week or two weeks the site begins running slower - and I see queries taking longer and longer to complete in SQL. I have a query that I like to use: USE master select text,wait_time,blocking_session_id AS "Block", percent_complete, * from sys.dm_exec_requests CROSS APPLY sys.dm_exec_sql_text(sql_handle) AS s2 order by start_time asc Which is fairly useful... it gives a snapshot of everything that's running right at that moment against your SQL server. What's nice is that even if your CPU is pegged at 100% for some reason and Activity Monitor is refusing to load (I'm sure some of you have been there) this query still returns and you can see what query is killing your DB. When I run this, or Activity Monitor during the times that SQL has begun to slow down I don't see any specific queries causing the issue - they are ALL running slower across the board. If I restart the MS SQL Service then everything is fine, it speeds right up - for a week or two until it happens again. Nothing that I can think of has changed, but this just started a few months ago... Ideas? --Added Please note that when this database slowdown happens it doesn't matter if we are getting 100K page views an hour (busier time of day) or 10K page views an hour (slow time) the queries all take a longer time to complete than normal. The server isn't really under stress - the CPU isn't high, the disk usage doesn't seem to be out of control... it feels like index fragmentation or something of the sort but that doesn't seem to be the case. As far as pasting results of the query I pasted above I really can't do that. The Query above lists the login of the user performing the task, the entire query, etc etc.. and I'd really not like to hand out the names of my databases, tables, columns and the logins online :)... I can tell you that the queries running at that time are normal, standard queries for our site that run all the time, nothing out of the norm.

  • Hyperic HQ- Monitor process statistics for 50+ processes on Linux machine

    - by Chris
    Is there an easy way to get metrics on all processes that start with the letters XYZ? I have about 80 processes that I have to monitor individually that all start with the prefix XYZ. I have created a query using the sigar shell: ps State.Name.sw=XYZ, which will give me a list of the processes that I want. What I need to do is define this list of processes through said query and collect and track statistics from the Process service: http://support.hyperic.com/display/hypcomm/Process+service What I need is 3 or 4 key statistics for each of the XYZ processes defined by my query to show up as graphs in the web front end. Note: Hyperic HQ server is installed on a windows machine and I'm monitoring a Linux box via an agent. Thanks, Chris Edit: Here is my try at a plugin that may give me what I want, but it's not being inventoried/detected by the Hyperic web UI. Simply pointing me to one of Hyperic's tutorials won't do. Thanks. <!DOCTYPE plugin [ <!ENTITY process-metrics SYSTEM "/pdk/plugins/process-metrics.xml">]> <plugin> <server name="ABCStats"> <config> <option name="process.query" description="Process Query" default="State.Name.sw=XYZ"/> </config> <metric name="Availability" alias="Availability" template="sigar:Type=ProcState,Arg=%process.query%:State" category="AVAILABILITY" indicator="true" units="percentage" collectionType="dynamic"/> &process-metrics; <plugin type="autoinventory"/> <plugin type="measurement" class="org.hyperic.hq.product.MeasurementPlugin"/> </server> </plugin>

  • Excel 2007 - Adding line breaks in a cell and no line over 50 characters

    - by Richard Drew
    I have notes stored in an excel cell. I add line breaks and dates every time I add a new note. I need to copy this to another program, but it has a line limit of 50 characters. I want a line break for each new date and for when each date's comment goes over 50 characters. I'm able to do one or the other, but I can't figure out how to do both. I'd prefer words not to be split up, but at this point I don't care. Below is some sample input. If needed for a SUBSTITUTE or REPLACE function, I could add a ~ before each date in my input as a delimiter. Sample Input: 07/03 - FU on query. Copies and history included. CC to Jane Doe and John Public 06/29 - Cust claiming not to have these and wrong PO on query form. Responded with inv sent dates and locations, correct PO values, and copies. 06/27 - New ticket opened using query form 06/12 - Opened ticket with helpdesk asking status 05/21 - Copy submitted to [email protected] 05/14 - Copy sent to John Public and [email protected] Ideal Output: 07/03 - FU on query. Copies and history included. CC to Jane Doe and John Public 06/29 - Cust claiming not to have these and wrong PO on query form. Responded with inv sent dates an d locations, correct PO values, and copies. 06/27 - New ticket opened using query form 06/12 - Opened ticket with helpdesk asking status 05/21 - Copy submitted to [email protected] om 05/14 - Copy sent to John Public and email@custome r.com

  • Cisco 3560+ipservices -- IGMP snooping issue with TTL=1

    - by Jander
    I've got a C3560 with Enhanced (IPSERVICES) image, routing multicast between its VLANs with no external multicast router. It's serving a test environment where developers may generate multicast traffic on arbitrary addresses. Everything is working fine except when someone sends out multicast traffic with TTL=1, in which case the multicast packet suppression fails and the traffic is broadcast to all members of the VLAN. It looks to me like because the TTL is 1, the multicast routing subsystem doesn't see the packets, so it doesn't create a mroute table entry. If I send out packets with TTL=2 briefly, then switch to TTL=1 packets, they are filtered correctly until the mroute entry expires. My question: is there some trick to getting the switch to filter the TTL=1 packets, or am I out of luck? Below are the relevant parts of the config, with a representative VLAN interface. I can provide more info as needed. #show run ... ip routing ip multicast-routing distributed no ip igmp snooping report-suppression ! interface Vlan44 ip address 172.23.44.1 255.255.255.0 no ip proxy-arp ip pim passive ... #show ip igmp snooping vlan 44 Global IGMP Snooping configuration: ------------------------------------------- IGMP snooping : Enabled IGMPv3 snooping (minimal) : Enabled Report suppression : Disabled TCN solicit query : Disabled TCN flood query count : 2 Robustness variable : 2 Last member query count : 2 Last member query interval : 1000 Vlan 44: -------- IGMP snooping : Enabled IGMPv2 immediate leave : Disabled Multicast router learning mode : pim-dvmrp CGMP interoperability mode : IGMP_ONLY Robustness variable : 2 Last member query count : 2 Last member query interval : 1000

  • MySQL Execution Time Spikes

    - by Brett
    I am having issues with MySQL all of the sudden today. Details: OS: CentOS release 5.7 Server type: Parallels virtuozzo container running on mediatemple DV 4.0 package Average total memory usage: <500mb Total memory usage allowed: 1gb (part of shared pool for emergency only, users are only guaranteed 500mb) Processor: 1ghz Main database sizes with most usage: 275mb & 107mb server stack: nginx 1.0.10, mysql 5.1.54, php 5.3.8 with php-fpm innodb_buffer_pool_size=100M php-fpm max children: 5 Webapps: custom php-based sites, magento & drupal slow query timeout is set to 1 second Steps I completed towards diagnosis: Cannot restart container yet - I will try later tonight when our domestic traffic has dropped Enabled mysql and php-fpm slowlog. Found functions that did DB queries in php-fpm slowlog were taking over 1s to complete at times Found some simple queries in mysql slowlog taking well over 1s to complete that should take less than 1s. Most interesting - execution time seems to spike at times. A query will take .2s a couple times, then one time it will take 8s to run the same query. These results were verified by running raw SQL queries through mysql command line. Top does not reveal anything too interesting Only resource related thing i can see is load averages much higher than normal Up until today, mysql has been fine, there have been no major changes to the db since yesterday. Sometimes things are so bad, I am seeing bad gateway errors after 60s of execution time. Innodb is doing on average 300-1400 reads/sec. Mysql is doing 3-10 queries/sec slow query count in 2 hours uptime is 171 (with slow timeout at 1 second) Tried restarting mysql, nginx, php-fpm multiple times For example: UPDATE `catalogsearch_query` SET `query_text` = 'EW 90', `num_results` = '7532', `popularity` = '99180', `redirect` = NULL, `synonym_for` = NULL, `store_id` = '1', `display_in_terms` = '1', `is_active` = '1', `is_processed` = '1', `updated_at` = '2012-05-08 21:38:31' WHERE (query_id='31'); This query took 17sec to complete one time, rest of the time around .079 sec. But varies, sometimes 1sec, sometimes .004 sec. This is running the same query, over and over with a couple seconds time in between each. Most tables are innodb, and sometimes I noticed the lock time taking 90% of the query execution time, but most of the time lock time is insignificant. Any idea what's going on here?
