  • Storing a looong lookup table

    - by inquisitive
    Background The product i am working on has a very long lookup-table. the table contains static data and cannot be auto generated. there are about 500 rows and 10 columns. columns have mostly integers and strings. to complicate the matters, there are actually two such tables. every row in table-1 maps to zero-or-more rows in table-2. we use an SQLite database with two tables. the product installer places the SQLite file in the installation directory. the application is written in dot-net and we use ADO to load the data once on startup. now, the lookup table grows. in each release a month, we add about 10 new entries existing entries are adjusted. every release we fine tune existing entries. The problem a team of (10) developers work on the lookup table. Code goes in the SVN, but the little devil the SQLite does not. this prevents multiple developers to work on it. we do take regular backups of the file, but proper versioning is not possible. we never know who did the breaking change. the worse thing is we dont know if there is any change at all. diff'ing databases is tedious if not impossible. the tables are expected to grow quite large in years to come and we would need developers to work in parallel on it. the data is business critical. we need to be able to audit changes made to it. Question What would be a solution for the problems outlines above? one idea was to transform the whole thing to XML and treat it like just another source file. that way SVN can do the versioning and we can work in parallel. but the data shows relational behavior. with XML we loose the unique and foreign-key constraints. also we cant query it with sql like ease. any help here will be appreciated.

  • How to create a lookup column that targets a Doc Lib and uses the 'Name' of the document?

    - by stlawrence
    How do you create a lookup column to a Document Library that uses the 'Name' of the document as the lookup value? I found a blog post that recommends adding another custom field like "FileName" and then using a item reciever to populate the custom field with the value from the Name field but that seems cheesy. Link to the blog in case people are interested: http://blogs.msdn.com/pranab/archive/2008/01/08/sharepoint-2007-moss-wss-issue-with-lookup-column-to-doc-lib-name-field.aspx I've got a bunch of custom document content types that I dont want to clutter with a work around that should really work anyway.

  • Optimizing hash lookup & memory performance in Go

    - by Moishe
    As an exercise, I'm implementing HashLife in Go. In brief, HashLife works by memoizing nodes in a quadtree so that once a given node's value in the future has been calculated, it can just be looked up instead of being re-calculated. So eg. if you have a node at the 8x8 level, you remember it by its four children (each at the 2x2 level). So next time you see an 8x8 node, when you calculate the next generation, you first check if you've already seen a node with those same four children. This is extended up through all levels of the quadtree, which gives you some pretty amazing optimizations if eg. you're 10 levels above the leaves. Unsurprisingly, it looks like the perfmance crux of this is the lookup of nodes by child-node values. Currently I have a hashmap of {&upper_left_node,&upper_right_node,&lower_left_node,&lower_right_node} -> node So my lookup function is this: func FindNode(ul, ur, ll, lr *Node) *Node { var node *Node var ok bool nc := NodeChildren{ul, ur, ll, lr} node, ok = NodeMap[nc] if ok { return node } node = &Node{ul, ur, ll, lr, 0, ul.Level + 1, nil} NodeMap[nc] = node return node } What I'm trying to figure out is if the "nc := NodeChildren..." line causes a memory allocation each time the function is called. If it does, can I/should I move the declaration to the global scope and just modify the values each time this function is called? Or is there a more efficient way to do this? Any advice/feedback would be welcome. (even coding style nits; this is literally the first thing I've written in Go so I'd love any feedback)

  • Showplan Operator of the Week – BookMark/Key Lookup

    Fabiano continues in his mission to describe the major Showplan Operators used by SQL Server's Query Optimiser. This week he meets a star, the Key Lookup, a stalwart performer, but most famous for its role in ill-performing queries where an index does not 'cover' the data required to execute the query. If you understand why, and in what circumstances, key lookups are slow, it helps greatly with optimising query performance.

  • TopComponent, Node, Lookup, Palette, and Visual Library

    - by Geertjan
    Here's a small example that puts together several pieces in the context of a NetBeans Platform application, i.e., TopComponent, Node, Lookup, Palette, and Visual Library: http://java.net/projects/nb-api-samples/sources/api-samples/show/versions/7.2/misc/CensusDesigner The result is a drag-and-drop user interface, i.e., drag items from the palette and drop them onto the window, that's all it does, nothing too fancy, just puts the basic NetBeans Platform pieces together in a pretty standard combination:

  • How to build up a lookup table in microcontroller?

    - by GiGi
    Hi, I am so confused about how to build up a 3-dimension lookup table. Is the template as follows: create a 3 dimensional array to store data. Then create linked list. Then create function 'insert' to put all the data into the array? As some book said, linked list should be static const, is it need to create another function to expand the list? Because the lookup table should be used in a microcontroller, it only needs to finish the operation of putting the data into the array and whenever want to find the data, it will be fast and easy to search. Could you help me with that and give me some suggestions? Thank you.

  • How to JNDI lookup from cluster 1 : a queue that exists in cluster 2 in Websphere 6?

    - by user347394
    I have a Websphere topology wherein in Cluster1, I have an MDB that's trying to publish to another MDB that resides in Cluster2. Since they're both in the same container, I tried simply Blockquote Context ctx = new InitialContext(); ctx.lookup("jms/MyQueue"); Blockquote The "jms/MyQueue" is configured in Cluster2. As you can see, this doesn't work!! 1) Do I have to provide an environment entry while creating the InitialContext? Even though both clusters are part of the same container? 2) If not, how then can I lookup the said queue in Cluster 2?

  • Setup Convergence Address Book DisplayName Lookup

    - by user13332755
    At Convergence Address Book the default lookup for 'Display Name' is the LDAP attribute 'cn', which leads into confusion if you start to setup 'displayName' LDAP attributes for your users. LDAP User Entry with diaplyName attribute: This behavior can be controlled by the configuration file xlate-inetorgperson.xml. Change the default value of XPATH abperson\entry\displayname from 'cn' to 'displayName'. <convergence_deploy_location>/config/templates/ab/corp-dir/xlate-inetorgperson.xml Note: In case the user has no 'displayName' attribute in LDAP you might noticed '...' at the user entry, if found via 'mail' attribute.

  • Fast lookup for organization hierarchy

    - by Élodie Petit
    I need a way to implement a fast lookup algorithm / system to find users very quickly in a multi-level department and multi-level employee/manager relation organization structure. Departments can have any level of departments and users directly connected to departments. User are connected to departments and other users at the same time. What would be the best approach to implement such a system? There will be approximately 2000 users and 30 departments. Is there a good way to hold all of this information on memory?

  • Lookup Field as a Site Column via CAML

    - by Rob Windsor
    I'm trying to create a Lookup Field as a Site Column via CAML. The list I want to use as the source of the lookup is created in the Feature Receiver so I don't know it's ID. I've read several blog posts that indicate that I can just put the path to the list in the List attribute. It seems from the comments on these post that this solution works for some people but not for others. I'm in the latter group. When I try to associate a content type that uses the lookup site column I: "Exception from HRESULT: 0x80040E07" <Field ID="{da94e56b-428f-4b95-b4c6-24aed0256475}" Name="Test_x0020_Lookup_x0020_Column" StaticName="Test_x0020_Lookup_x0020_Column" DisplayName="Test Lookup Column" Type="Lookup" Required="FALSE" List="Lists/Test" ShowField="Title" PrependId="TRUE" Group="Test Site Columns" /> <ContentType ID="0x0100B6D92594DDCE8E479D0EB0C414C463B0" Name="Test Lookup Content Type" Version="0" Group="Test Content Types"> <FieldRefs> <FieldRef ID="{da94e56b-428f-4b95-b4c6-24aed0256475}" Name="Test_x0020_Lookup_x0020_Column" Required="TRUE" /> </FieldRefs> </ContentType>

  • OpenGL - Cascaded shadow mapping - Texture lookup

    - by Silverlan
    I'm trying to implement cascaded shadow mapping in my engine, but I'm somewhat stuck at the last step. For testing purposes I've made sure all cascades encompass my entire scene. The result is currently this: The different intensity of the cascades is not on purpose, it's actually the problem. This is how I do the texture lookup for the shadow maps inside the fragment shader: layout(std140) uniform CSM { vec4 csmFard; // far distances for each cascade mat4 csmVP[4]; // View-Projection Matrix int numCascades; // Number of cascades to use. In this example it's 4. }; uniform sampler2DArrayShadow csmTextureArray; // The 4 shadow maps in vec4 csmPos[4]; // Vertex position in shadow MVP space float GetShadowCoefficient() { int index = numCascades -1; vec4 shadowCoord; for(int i=0;i<numCascades;i++) { if(gl_FragCoord.z < csmFard[i]) { shadowCoord = csmPos[i]; index = i; break; } } shadowCoord.w = shadowCoord.z; shadowCoord.z = float(index); shadowCoord.x = shadowCoord.x *0.5f +0.5f; shadowCoord.y = shadowCoord.y *0.5f +0.5f; return shadow2DArray(csmTextureArray,shadowCoord).x; } I then use the return value and simply multiply it with the diffuse color. That explains the different intensity of the cascades, since I'm grabbing the depth value directly from the texture. I've tried to do a depth comparison instead, but with limited success: [...] // Same code as above shadowCoord.w = shadowCoord.z; shadowCoord.z = float(index); shadowCoord.x = shadowCoord.x *0.5f +0.5f; shadowCoord.y = shadowCoord.y *0.5f +0.5f; float z = shadow2DArray(csmTextureArray,shadowCoord).x; if(z < shadowCoord.w) return 0.25f; return 1.f; } While this does give me the same shadow value everywhere, it only works for the first cascade, all others are blank: (I colored the cascades because otherwise the transitions wouldn't be visible in this case) What am I missing here?

  • SSIS - Range lookups

    - by Repieter
      When developing an ETL solution in SSIS we sometimes need to do range lookups in SSIS. Several solutions for this can be found on the internet, but now we have built another solution which I would like to share, since it's pretty easy to implement and the performance is fast.   You can download the sample package to see how it works. Make sure you have the AdventureWorks2008R2 and AdventureWorksDW2008R2 databases installed. (Apologies for the layout of this blog, I don't do this too often :))   To give a little bit more information about the example, this is basically what is does: we load a facttable and do an SCD type 2 lookup operation of the Product dimension. This is done with a script component.   First we query the Data warehouse to create the lookup dataset. The query that is used for that is:   SELECT     [ProductKey]     ,[ProductAlternateKey]     ,[StartDate]     ,ISNULL([EndDate], '9999-01-01') AS EndDate FROM [DimProduct]     The output of this query is stored in a DataTable:     string lookupQuery = @"                         SELECT                             [ProductKey]                             ,[ProductAlternateKey]                             ,[StartDate]                             ,ISNULL([EndDate], '9999-01-01') AS EndDate                         FROM [DimProduct]";           OleDbCommand oleDbCommand = new OleDbCommand(lookupQuery, _oleDbConnection);         OleDbDataAdapter adapter = new OleDbDataAdapter(oleDbCommand);           _dataTable = new DataTable();         adapter.Fill(_dataTable);     Now that the dimension data is stored in the DataTable we use the following method to do the actual lookup:   public int RangeLookup(string businessKey, DateTime lookupDate)     {         // set default return value (Unknown)         int result = -1;           DataRow[] filteredRows;         filteredRows = _dataTable.Select(string.Format("ProductAlternateKey = '{0}'", businessKey));           for (int i = 0; i < filteredRows.Length; i++)         {             // check if the lookupdate is found between the startdate and enddate of any of the records             if (lookupDate >= (DateTime)filteredRows[i][2] && lookupDate < (DateTime)filteredRows[i][3])             {                 result = (filteredRows[i][0] == null) ? -1 : (int)filteredRows[i][0];                 break;             }         }           filteredRows = null;           return result;     }       This method is executed for every row that passes the script component. This is implemented in the ProcessInputRow method   public override void Input0_ProcessInputRow(Input0Buffer Row)     {         // Perform the lookup operation on the current row and put the value in the Surrogate Key Attribute         Row.ProductKey = RangeLookup(Row.ProductNumber, Row.OrderDate);     }   Now what actually happens?!   1. Every record passes the business key and the orderdate to the RangeLookup method. 2. The DataTable is then filtered on the business key of the current record. The output is stored in a DataRow [] object. 3. We loop over the DataRow[] object to see where the orderdate meets the following expression: (lookupDate >= (DateTime)filteredRows[i][2] && lookupDate < (DateTime)filteredRows[i][3]) 4. When the expression returns true (so where the data is between the Startdate and the EndDate), the surrogate key of the dimension record is returned   We have done some testing with this solution and it works great for us. Hope others can use this example to do their range lookups.

  • Remote EJB lookup issue with WebSphere 6.1

    - by marc dauncey
    I've seen this question asked before, but I've tried various solutions proposed, to no avail. Essentially, I have two EJB enterprise applications, that need to communicate with one another. The first is a web application, the second is a search server - they are located on different development servers, not in the same node, cell, or JVM, although they are on the same physical box. I'm doing the JNDI lookup via IIOP, and the URL I am using is as follows: iiop://searchserver:2819 In my hosts file, I've set searchserver to 127.0.0.1. The ports for my search server are bound to this hostname too. However, when the web app (that uses Spring btw) attempts to lookup the search EJB, it fails with the following error. This is driving me nuts, surely this kind of comms between the servers should be fairly simple to get working. I've checked the ports and they are correct. I note that the exception says the initial context is H00723Node03Cell/nodes/H00723Node03/servers/server1, name: ejb/com/hmv/dataaccess/ejb/hmvsearch/HMVSearchHome. This is the web apps server NOT the search server. Is this correct? How can I get Spring to use the right context?

    I am sick of doing blocks of code like this for various bits of code I have: if (dict.ContainsKey[key]) { dict[key] = value; } else { dict.Add(key,value); } and for lookups (i.e. key - list of value) if (lookup.ContainsKey[key]) { lookup[key].Add(value); } else { lookup.Add(new List<valuetype>); lookup[key].Add(value); } Is there another collections lib or extension method I should use to do this in one line of code no matter what the key and value types are? e.g. dict.AddOrUpdate(key,value) lookup.AddOrUpdate(key,value)

  • Using Excel Lookup Function and Handling Case Where No Matches Exist

    - by Dave
    I'm using Excel to enter data for an event where people register. A high percentage of the registrants will have registered for previous events, so we can their name and ID number. I'm trying to use the LOOKUP function in Excel to lookup the name and then populate the ID field with their ID number. This works well unless the value that is looked up is a new user that we don't already have details for. However, if the LOOKUP function can not find an exact match, it chooses the largest value in the lookup_range that is less than or equal to the value. This causes a problem since you can't tell if the match was exact (and the data is correct) or not exact and the match is incorrect. How do I catch non-matches and handle separately?

  • How to lookup a value in a table with multiple criteria

    - by php-b-grader
    I have a data sheet with multiple values in multiple columns. I have a qty and a current price which when multiplied out gives me the current revenue (CurRev). I want to use this lookup table to give me the new revenue (NewRev) from the new price but can't figure out how to do multiple ifs in a lookup. What I want is to build a new column that checks the "Product", "Tier" and "Location/State" and gives me the new price from the lookup table (above) and then multiply that by the qty. e.g. Data > Product, Tier, Location, Qty, CurRev, NewRev > Product1, Tier1, VIC, 2, $1000.00, $6000 (2 x $3000) > Product2, Tier3, NSW, 1, $100.00, $200 (1 x $200) > Product1, Tier3, SA, 5, $250.00, $750 (5 x $150) > Product3, Tier1, ACT, 5, $100.00, $500(5 x $100) > Product2, Tier3, QLD, 2, $150.00, $240 (2 x $240) Worst case, if I just get the new rate I can create another column

  • how sharepoint lookup column store its values?

    - by ps123
    Hello, I was trying to create a custom field type similar to lookup column just mine is filtered lookup column.Its working fine but I wanted to implement the same functionality like lookup column does,by that I mean: For e.g lookup column is having title of some list so it stores its value as SPListiem.ID#;title....but it shows only title when we r selecting or editing value in it. I am using listboxes and doing listbox.Items.Add(title); but how to get Id also and specially hidden from users like lookup column does....means I can do like this... listbox.Items.Add(title+"#;" + SPListitem.ID)... but I dont want this.... Any idea how to achieve this...
