  • Getting a query to index seek (rather than scan)

    - by PaulB
    Running the following query (SQL Server 2000) the execution plan shows that it used an index seek and Profiler shows it's doing 71 reads with a duration of 0. select top 1 id from table where name = '0010000546163' order by id desc Contrast that with the following with uses an index scan with 8500 reads and a duration of about a second. declare @p varchar(20) select @p = '0010000546163' select top 1 id from table where name = @p order by id desc Why is the execution plan different? Is there a way to change the second method to seek? thanks EDIT Table looks like CREATE TABLE [table] ( [Id] [int] IDENTITY (1, 1) NOT NULL , [Name] [varchar] (13) COLLATE Latin1_General_CI_AS NOT NULL) Id is primary clustered key There is a non-unique index on Name and a unique composite index on id/name There are other columns - left them out for brevity

  • Links from Google appending index.php to my URL

    - by davykiash
    I recently put up a site and I have been doing some SEO. However I noticed that links from Google search append index.php to my links. For example a site page which clearly appears as www.example.com/index/why on search together with correct content sample when clicked on ends up in the new browser as www.example.com/index.php/why Note that on my site all links are redirected to SSL and I use the MVC stucture. Any directives that am may be missing?

  • Database is very slow when creating an index

    - by kaliyaperumal M
    My database has around 25 core numbers, in that weekly basis I need to create an index and drop index. While creating the index it takes long time to complete, my log file also keeps on increasing, and when I delete some numbers from that table also taking too much time (because weekly basis I have to delete 30 to 50 lack numbers and add 30 to 40 lack new number also). Can u please give me the proper solution..

  • Clustered Index

    - by Charu
    Which type of index(clustered/non clustrered) should be used for Insert/Update/Delete statement in SQL Server. I know it creates an additional overhead but is it better in performance as comparison to non clustered index? Also which index should be use for Select statements in SQL Server?

  • sort list(of string()) using a variable index into string() as key - vb.net

    - by tullynyguy
    I have a List(of String()). I have written a custom comparer (implements IComparer(of string)) to do an alphanumeric sort. Is there a way to sort the List using a given index to determine which position in the String() to sort by? In other words one time I might sort by Index = 0 and another time by Index = 3. The length of all String() in the list is the same. For reference this question is similar to Sort List<String[]> except I am using VB.net and that question is hardwired to Index=0.

  • Python finding index in a array

    - by NIH
    I am trying to see if a company from a list of companies is in a line in a file. If it is I utilize the index of that company to increment a variable in another array. The following is my python code. I keep getting the following error: AttributeError: 'set' object has no attribute 'index'. I cannot figure out what is going wrong and think the error is the line that is surrounded by **. companies={'white house black market', 'macy','nordstrom','filene','walmart'} positives=[0 for x in xrange(len(companies))] negatives=[0 for x in xrange(len(companies))] for line in f: for company in companies: if company in line.lower(): words=tokenize.word_tokenize(line) bag=bag_of_words(words) classif=classifier.classify(bag) if classif=='pos': **indice =companies.index(company)** positives[indice]+=1 elif classif=='neg': **indice =companies.index(company)** negatives[indice]+=1

  • Remove urls to unidex blog content from google, then copy blogs content to new blog [closed]

    - by sam
    Possible Duplicate: migrating PR / rankings from one site to another Ive been writing a blog for the past yr or so, with about 300 published articles, the blog have been running under a subdomain blog.mysite.com We are no looking to change the url of our site, so the blog is going to have to be ported over to a subdoamin on the new site. We would really like to keep the backlog / archive of all the articles we have written but dont wont to be penalized for having duplicate content, could we just remove / unindex the urls from google in webmaster tools then export the blog and import it back to our new blog ? Would google still see this a duplicate content or becuase ive removed the urls have they no longer got a copy of it ? thanks

  • Why Google skips page title

    - by Bob
    I have no idea why this is happening. An example http://www.londonofficespace.com/ofdj17062004934429t.htm Title tag is: Unfurnished Office Space Wimbledon – Serviced Office on Lombard Road SW19 But is indexed as: Lombard Road – SW19 - London Office Space If you look in the source code and search for this portion ‘Lombard Road – SW19’ You then find that it's next to an office image alt=’Lombard Road – SW19’. The only thing I could think of is that the spider somehow ‘skips’ our title tag and grabs this bit, and then inserts the name of the site (but WHY?) Is there anything I can do with this? or is this a Google behaviour?

  • Google indexing wrong domain that does not work

    - by user174117
    Can anyone tell me why Google indexes a site http://0.3c.7aae.static.theplanet.com instead of the actual domain name (my domain was registered with webmaster tools). The aforementioned link was linking to my site, but has now become a broken link. Initially I tried 301 directs, but nothing worked. The hosting company cannot explain why. Leaving me wondering what to do? Any guidance would be appreciated. Thks

  • Weird 301 redirection by google crawler

    - by Ace
    I have some pages on my website www.acethem.com which are having 301 redirection but they are not actually 301 redirects. e.g. www.acethem.com/pastpapers/by-year/2007/ is seen as a 301 redirection to www.acethem.com/pastpapers/by-year by google (I am using "Fetch as google" in webmaster tools. Now more weird: My paginated pages with page = 10 are all redirected to homepage: http://www.acethem.com/pastpapers/o-level/chemistry/page/10/ while http://www.acethem.com/pastpapers/o-level/chemistry/page/9/ is working properly in google crawler. Note that all these pages work fine with no redirect in browsers. Sidenote: on www.acethem.com/pastpapers/by-year/2007/, the facebook share button also points to www.acethem.com/pastpapers/by-year/.

  • Meta description of my blog post changes

    - by Aadarsh sojitra
    I have some problems in Meta description tags in my Blogger blog. When I update my pages in search engine with the help of the Fetch as Google feature in GWT, all my blog's results comes with a correct meta description like Today I am back with a reason that "WHY IS ORIGINAL MEMORY IN HARD-DISK IS LESS THAN PRINTED" on a box. If we buy any hard-disk or a pen drive... But after approx 5-6 days, it changes to my blog's default meta description. This is also happening after changing the default meta description of my blog. I want only one answer that why its happening? After deleting my blog and creating a new blog with the same name this problem was solved. Why this problem was solved? - I am asking this question because to solve problems in the future.

  • How can I prevent HTTPS on another domain from wrongly showing on my HTTP-only domain?

    - by Earlz
    So, I have a blog at domain.com. This blog is HTTP-only because I would gain almost nothing from adding SSL support. I have a web service now that I want to enable SSL support on that runs on the same server and IP address as my blog. I got it all working pretty easily, but not if I go to https://domain.com I will see a huge warning about an SSL certificate error and then if I click "ok" through the warning, I'll see the web service with SSL support, not my blog. My biggest fear with this scheme is Google indexing an HTTPS version of it and penalizing my blog because the content between the two doesn't match. How can I somehow for my blog's domain to either not serve anything on HTTPS, or to redirect back to my HTTP blog, or to serve my blog, but with an invalid SSL certificate? What can I do, preferably without buying another dedicated IP for my website?

  • Unindexing my tumblr blogs content and moving it to another tumblr blog

    - by sam
    ive been writing a tumblr blog for the past yr or so, ive writen about 300 articles, but now i need to move the blog to another site. (before it was running under blog.mysite.com and i now want it to run under blog.my*new*site.com) I want to keep the archived articles and have them on the new site, so what i was hoping to do was export the blog from tumblr, go into webmaster tools remove all the blogs indexed urls from google webmaster, then make a new tumblr blog and import the posts. Would google see this as new content as ive deleted their indexed copy ? Could i just move the mapping of the tumblr blog to the new subdomain, but in doing this i would lose all the pr and it would still look like duplicate content whats the best way to approach this ?

  • Loading Wavefront Data into VAO and Render It

    - by Jordan LaPrise
    I have successfully loaded a triangulated wavefront(.obj) into 6 vectors, the first 3 vectors contain the locations for vertices, uv coords, and normals. The last three have the indices stored for each of the faces. I have been looking into using VAO's and VBO's to render, and I'm not quite sure how to load and render the data. One of my biggest concerns is the fact that indexed rendering only allows you to have one array of indices, meaning I somehow have to make all of the first three vectors the same size, the only way I thought of doing this, is to make 3 new vertex's of equal size, and load in the data for each face, but that would completely defeat the purpose of indexing. Any help would be appreciated. Thanks in advance, Jordan

  • my domain is well indexed just in my country

    - by ali
    This is my domain : http://yon.ir and it mainly should be shown in search results with the keyword "????? ????? ????" in country of Iran it is shown in google search results with rank 13 (with that keyword) which is logical but with IPs of other countries , it's not shown even in 10 first google result pages. (but the domain is indexed and when I search the whole domain title, it shows up my site at first) it's about 10 days with this manner and the domain is not new .(it was working with its previous owner before) So , what's the problem here?

  • how can I specify interleaved vertex attributes and vertex indices

    - by freefallr
    I'm writing a generic ShaderProgram class that compiles a set of Shader objects, passes args to the shader (like vertex position, vertex normal, tex coords etc), then links the shader components into a shader program, for use with glDrawArrays. My vertex data already exists in a VertexBufferObject that uses the following data structure to create a vertex buffer: class CustomVertex { public: float m_Position[3]; // x, y, z // offset 0, size = 3*sizeof(float) float m_TexCoords[2]; // u, v // offset 3*sizeof(float), size = 2*sizeof(float) float m_Normal[3]; // nx, ny, nz; float colour[4]; // r, g, b, a float padding[20]; // padded for performance }; I've already written a working VertexBufferObject class that creates a vertex buffer object from an array of CustomVertex objects. This array is said to be interleaved. It renders successfully with the following code: void VertexBufferObject::Draw() { if( ! m_bInitialized ) return; glBindBuffer( GL_ARRAY_BUFFER, m_nVboId ); glBindBuffer( GL_ELEMENT_ARRAY_BUFFER, m_nVboIdIndex ); glEnableClientState( GL_VERTEX_ARRAY ); glEnableClientState( GL_TEXTURE_COORD_ARRAY ); glEnableClientState( GL_NORMAL_ARRAY ); glEnableClientState( GL_COLOR_ARRAY ); glVertexPointer( 3, GL_FLOAT, sizeof(CustomVertex), ((char*)NULL + 0) ); glTexCoordPointer(3, GL_FLOAT, sizeof(CustomVertex), ((char*)NULL + 12)); glNormalPointer(GL_FLOAT, sizeof(CustomVertex), ((char*)NULL + 20)); glColorPointer(3, GL_FLOAT, sizeof(CustomVertex), ((char*)NULL + 32)); glDrawElements( GL_TRIANGLES, m_nNumIndices, GL_UNSIGNED_INT, ((char*)NULL + 0) ); glDisableClientState( GL_VERTEX_ARRAY ); glDisableClientState( GL_TEXTURE_COORD_ARRAY ); glDisableClientState( GL_NORMAL_ARRAY ); glDisableClientState( GL_COLOR_ARRAY ); glBindBuffer( GL_ARRAY_BUFFER, 0 ); glBindBuffer( GL_ELEMENT_ARRAY_BUFFER, 0 ); } Back to the Vertex Array Object though. My code for creating the Vertex Array object is as follows. This is performed before the ShaderProgram runtime linking stage, and no glErrors are reported after its steps. // Specify the shader arg locations (e.g. their order in the shader code) for( int n = 0; n < vShaderArgs.size(); n ++) glBindAttribLocation( m_nProgramId, n, vShaderArgs[n].sFieldName.c_str() ); // Create and bind to a vertex array object, which stores the relationship between // the buffer and the input attributes glGenVertexArrays( 1, &m_nVaoHandle ); glBindVertexArray( m_nVaoHandle ); // Enable the vertex attribute array (we're using interleaved array, since its faster) glBindBuffer( GL_ARRAY_BUFFER, vShaderArgs[0].nVboId ); glBindBuffer( GL_ELEMENT_ARRAY_BUFFER, vShaderArgs[0].nVboIndexId ); // vertex data for( int n = 0; n < vShaderArgs.size(); n ++ ) { glEnableVertexAttribArray(n); glVertexAttribPointer( n, vShaderArgs[n].nFieldSize, GL_FLOAT, GL_FALSE, vShaderArgs[n].nStride, (GLubyte *) NULL + vShaderArgs[n].nFieldOffset ); AppLog::Ref().OutputGlErrors(); } This doesn't render correctly at all. I get a pattern of white specks onscreen, in the shape of the terrain rectangle, but there are no regular lines etc. Here's the code I use for rendering: void ShaderProgram::Draw() { using namespace AntiMatter; if( ! m_nShaderProgramId || ! m_nVaoHandle ) { AppLog::Ref().LogMsg("ShaderProgram::Draw() Couldn't draw object, as initialization of ShaderProgram is incomplete"); return; } glUseProgram( m_nShaderProgramId ); glBindVertexArray( m_nVaoHandle ); glDrawArrays( GL_TRIANGLES, 0, m_nNumTris ); glBindVertexArray(0); glUseProgram(0); } Can anyone see errors or omissions in either the VAO creation code or rendering code? thanks!

  • Should I use rel=index or rel=contents in this instance?

    - by Martin Bean
    I’m creating an MMA website. There’s the home page, there’s a fighters section whose index page lists fighters in the organisation, and then each fighter has a profile page. The URL structure is like this: / /fighters/ /fighters/john-doe My question is: on the fighter’s profile page I want to link to the fighters index page (/fighters). In my HTML page, which meta tag would be the most appropriate? <link href="/fighters/" rel="index" /> Or: <link href="/fighters/" rel="contents" /> I’m having trouble distinguishing which would be best, and whether rel="index" would be the index for the whole site or the current page/section I’m viewing?

  • How do I remove a LOT of indexed pages from Google?

    - by Thierry
    A few weeks ago we have figured out that Google has indexed some information we would rather keep in some confidentiality, in the format of individual PDF files. Our assumption was that this was a problem with our robots.txt we had overlooked. Even though we are not sure whether or not this is the case, we are certain that the robots.txt file is in a valid format and is, according to Google's webmaster tools, blocking the files. However, even after this adjustment that has been made weeks ago, Google still has the PDF files indexed, but does tell us further information cannot be provided due to the robots.txt file being present. As you can hopefully understand, this is unwanted behaviour due to the nature of the documents. I am aware that there is a request page being provided by Google for this purpose, but there are a lot of files. Is there an easier way to get Google to remove all of the files from its search engine? If not, is there anything else you could advise us to do besides manually requesting Google to remove every single page? Thanks in advance.

  • Wrong content for URL cache on Google

    - by user32592
    I have this website natural-track.com and when I do a cache check I get a completely different website,This is Google's cache of http://www.backpackers-planet.com/modules.php?name=Web_Links&l_op=visit&lid=3379 , unrelated to my site. I have checked with the host, they say all is well on their side. How can we fix it? The site also went off from Google Search. We are about to rebuild this site to a better professional platform but first we would like to have an idea of what happened and how to fix it.
