  • Need ad-hoc reporting component

    - by Nelson
    We need some simple ad-hoc reporting solution for our ASP.NET web-site. Just an ability to build a query with user friendly interface, then show the result of this query in some table and maybe export it to Excel or print. The solution must be quite easy for end users (our site visitors) who know nothing about databases, SQL and other tech stuff.

  • Search the Quartz maps

    - by user197127
    Hi, I would like to store some properties in the quartz datastore (jdbc) and then be able to find all triggers/jobs that match. E.g. store the user id related to a trigger and then query like user_id=555. Previously, I used to query the database directly but this is naturally not a good way. Anyone has another suggestion on how to accomplish this? Thanks.

  • MSSQL 2005: Update rows in a specified order (like ORDER BY)?

    - by JMTyler
    I want to update rows of a table in a specific order, like one would expect if including an ORDER BY clause, but MS SQL does not support the ORDER BY clause in UPDATE queries. I have checked out this question which supplied a nice solution, but my query is a bit more complicated than the one specified there. UPDATE TableA AS Parent SET Parent.ColA = Parent.ColA + (SELECT TOP 1 Child.ColA FROM TableA AS Child WHERE Child.ParentColB = Parent.ColB ORDER BY Child.Priority) ORDER BY Parent.Depth DESC; So, what I'm hoping that you'll notice is that a single table (TableA) contains a hierarchy of rows, wherein one row can be the parent or child of any other row. The rows need to be updated in order from the deepest child up to the root parent. This is because TableA.ColA must contain an up-to-date concatenation of its own current value with the values of its children (I realize this query only concats with one child, but that is for the sake of simplicity - the purpose of the example in this question does not necessitate any more verbosity), therefore the query must update from the bottom up. The solution suggested in the question I noted above is as follows: UPDATE messages SET status=10 WHERE ID in (SELECT TOP (10) Id FROM Table WHERE status=0 ORDER BY priority DESC ); The reason that I don't think I can use this solution is because I am referencing column values from the parent table inside my subquery (see WHERE Child.ParentColB = Parent.ColB), and I don't think two sibling subqueries would have access to each others' data. So far I have only determined one way to merge that suggested solution with my current problem, and I don't think it works. UPDATE TableA AS Parent SET Parent.ColA = Parent.ColA + (SELECT TOP 1 Child.ColA FROM TableA AS Child WHERE Child.ParentColB = Parent.ColB ORDER BY Child.Priority) WHERE Parent.Id IN (SELECT Id FROM TableA ORDER BY Parent.Depth DESC); The WHERE..IN subquery will not actually return a subset of the rows, it will just return the full list of IDs in the order that I want. However (I don't know for sure - please tell me if I'm wrong) I think that the WHERE..IN clause will not care about the order of IDs within the parentheses - it will just check the ID of the row it currently wants to update to see if it's in that list (which, they all are) in whatever order it is already trying to update... Which would just be a total waste of cycles, because it wouldn't change anything. So, in conclusion, I have looked around and can't seem to figure out a way to update in a specified order (and included the reason I need to update in that order, because I am sure I would otherwise get the ever-so-useful "why?" answers) and I am now hitting up Stack Overflow to see if any of you gurus out there who know more about SQL than I do (which isn't saying much) know of an efficient way to do this. It's particularly important that I only use a single query to complete this action. A long question, but I wanted to cover my bases and give you guys as much info to feed off of as possible. :) Any thoughts?

  • How to exclude a filter from a facet?

    - by gjb
    I have come from a Solr background and am trying to find the equivalent of "tagging" and "excluding" in Elasticsearch. In the following example, how can I exclude the price filter from the calculation of the prices facet? In other words, the prices facet should take into account all of the filters except for price. { query : { "filtered" : { "query" : { "match_all" : {} }, "filter" : { "and" : [ { "term" : { "colour" : "Red" } }, { "term" : { "feature" : "Square" } }, { "term" : { "feature" : "Shiny" } }, { "range" : { "price" : { "from" : "10", "to" : "20" } } } ] } } }, "facets" : { "colours" : { "terms" : { "field" : "colour" } }, "features" : { "terms" : { "field" : "feature" } }, "prices" : { "statistical" : { "field" : "price" } } } }

  • Tuples vs. Anonymous Types vs. Expando object. (in regards to LINQ queries)

    - by punkouter
    I am a beginner who finally started understanding anonymous types. (see old post http://stackoverflow.com/questions/3010147/what-is-the-return-type-for-a-anonymous-linq-query-select-what-is-the-best-way-t) So in LINQ queries you form the type of return value you want within the linq query right? It seems the way to do this is anonymous type right? Can someone explain to me if and when I could use a Tuple/Expando object instead? They all seem very simliar?

    - by chama
    I'm trying to compare the schemas of two tables that exist in different databases. So far, I have this query SELECT * FROM sys.columns WHERE object_id = OBJECT_ID('table1') The only thing is that I don't know how to use the sys.columns to reference a database other than the one that the query is connected to. I tried this SELECT * FROM db.sys.columns WHERE object_id = OBJECT_ID('table1') but it didn't find anything. I'm using SQL Server 2005 Any suggestions? thanks!
