  • Speed up a web service for auto complete and avoid too many method calls.

    - by jphenow
    So I've got my jquery autocomplete 'working,' but its a little fidgety since I call the webservice method each time a keydown() fires so I get lots of methods hanging and sometimes to get the "auto" to work I have to type it out and backspace a bit because i'm assuming it got its return value a little slow. I've limited the query results to 8 to mininmize time. Is there anything i can do to make this a little snappier? This thing seems near useless if I don't get it a little more responsive. javascript $("#clientAutoNames").keydown(function () { $.ajax({ type: "POST", url: "WebService.asmx/LoadData", data: "{'input':" + JSON.stringify($("#clientAutoNames").val()) + "}", contentType: "application/json; charset=utf-8", dataType: "json", success: function (data) { if (data.d != null) { var serviceScript = data.d; } $("#autoNames").html(serviceScript); $('#clientAutoNames').autocomplete({ minLength: 2, source: autoNames, delay: 100, focus: function (event, ui) { $('#project').val(ui.item.label); return false; }, select: function (event, ui) { $('#clientAutoNames').val(ui.item.label); $('#projectid').val(ui.item.value); $('#project-description').html(ui.item.desc); pkey = $('#project-id').val; return false; } }) .data("autocomplete")._renderItem = function (ul, item) { return $("<li></li>") .data("item.autocomplete", item) .append("<a>" + item.label + "<br>" + item.desc + "</a>") .appendTo(ul); } } }); }); WebService.asmx <WebMethod()> _ Public Function LoadData(ByVal input As String) As String Dim result As String = "<script>var autoNames = [" Dim sqlOut As Data.SqlClient.SqlDataReader Dim connstring As String = *Datasource* Dim strSql As String = "SELECT TOP 2 * FROM v_Clients WHERE (SearchName Like '" + input + "%') ORDER BY SearchName" Dim cnn As Data.SqlClient.SqlConnection = New Data.SqlClient.SqlConnection(connstring) Dim cmd As Data.SqlClient.SqlCommand = New Data.SqlClient.SqlCommand(strSql, cnn) cnn.Open() sqlOut = cmd.ExecuteReader() Dim c As Integer = 0 While sqlOut.Read() result = result + "{" result = result + "value: '" + sqlOut("ContactID").ToString() + "'," result = result + "label: '" + sqlOut("SearchName").ToString() + "'," 'result = result + "desc: '" + title + " from " + company + "'," result = result + "}," End While result = result + "];</script>" sqlOut.Close() cnn.Close() Return result End Function I'm sure I'm just going about this slightly wrong or not doing a better balance of calls or something. Greatly appreciated!

  • A better understanding of the relations beetween database tables

    - by Nistor Alexandru
    Hi I am trying to get a better understanding of relational databases and there is something that I keep bumping into and don't understand.Let's take this two tables: In this case Login.ID is the primary key with auto_increment set and Profile.ID_LOGIN is the Foreign KEY.When a user is created and it's username and password is stored in the login database does the ID coresponding to the curesnt username and password get automaticly added into ID_LOGIN or do I have to create an SQL statement to do this? If I have to create a SQL statement how should I aproach adding the ID_LOGIN to make sure I am adding it corectly?

  • Table index design

    - by Swoosh
    I would like to add index(s) to my table. I am looking for general ideas how to add more indexes to a table. Other than the PK clustered. I would like to know what to look for when I am doing this. So, my example: This table (let's call it TASK table) is going to be the biggest table of the whole application. Expecting millions records. IMPORTANT: massive bulk-insert is adding data in this table table has 27 columns: (so far, and counting :D ) int x 9 columns = id-s varchar x 10 columns bit x 2 columns datetime x 5 columns INT COLUMNS all of these are INT ID-s but from tables that are usually smaller than Task table (10-50 records max), example: Status table (with values like "open", "closed") or Priority table (with values like "important", "not so important", "normal") there is also a column like "parent-ID" (self - ID) join: all the "small" tables have PK, the usual way ... clustered STRING COLUMNS there is a (Company) column (string!) that is something like "5 characters long all the time" and every user will be restricted using this one. If in Task there are 15 different "Companies" the logged in user would only see one. So there's always a filter on this one. Might be a good idea to add an index to this column? DATE COLUMNS I think they don't index these ... right? Or can / should be?

  • Table Naming Dilemma: Singular vs. Plural Names

    - by ProfK
    Convention has it that table names should be the singular of the entity that they store attributes of. I dislike any T-SQL that requires square brackets around names, but I have renamed a Users table to the singular, forever sentencing those using the table to sometimes have to use brackets. My gut feel is that it is more correct to stay with the singular, but my gut feel is also that brackets indicate undesirables like column names with spaces in them etc. Should I stay, or should I go?

  • Select rows in random order and then reverse it

    - by Faruz
    I need to select rows in random order and return a query which holds the rows in both regular order and in reverse order. This is done to simulate a fantasy draft for a basketball game I'm working on. For example, I need a result set as followed: team1 1 team2 2 team6 3 team9 4 team9 5 team6 6 team2 7 team1 8 As you can see, the first four teams are random then then following four are in reverse order. Hope I managed to explain the problem, if not - please comment and I'll explain further.

  • Need help/suggestions for creating fantasy sports scoring databases and queries

    - by MGumbel
    I'm trying to create a website for my friends and I to keep track of fantasy sports scoring. So far, I've been doing the calculations and storage in Excel, which is very tedious. I'm trying to make it more simplified and automated through a SQL database that I can then wrap a web app around to enter daily stat updates. It's premised on our participation in another commercial site where we trade virtual shares of athletes, and thus acquire an "ownership percentage" in each athlete. For instance, if there are 100 shares of AROD, and I own 10 shares, then I own 10%. It then applies this to traditional baseball rotisserie scoring. So, for instance, if AROD has 1 HR today, then his adjusted HR stat would be 1.10. If he also has 2 RBI's, then his adjusted RBI stat today would be 2.20, based on (2 x 1.10)(1 to normalize the stat, and the .10 to represent the ownership percentage). All the stats for my team would then be summed each day and added to my stat history to come to an aggregated total. After that, points are allocated based on the ranking of each participant in each category at the end of the day. E.g. if there are 10 participants, and I have the highest total aggregate number of Adjusted HR's, then I get 10 pts. The points are then summed across the different stat categories to come up with a total point ranking for that day. An added difficulty is that ownership %'s can change on a daily basis. So far, in playing around with different schema, I don't know that having a separate table for each athlete's stats and each player's ownership %'s is the wisest choice. It seems to me that simply having two tables, one that contains the daily stat information for each athlete, and another that shows the ownership % of each player. My friend suggested using a start and end date for each ownership % to represent the potential daily changes in this category. I'm admittedly new to database development, so any suggestions on query code would be appreciated.

  • Consolidating values in a junction table

    - by senloe
    I have the following schema: Parcels Segments SegmentsParcels ========= ========== ================= ParcelID SegmentID ParcelID ... Name SegmentID ... id A user of the data wants to consolidate Segments.Names and gave me a list of current Segment.Names mapped to new Segment.Names (all of which currently exist). So now I have this list in a temporary table with the currentID and newID to map to. What I want to do is update the SegmentID in SegmentsParcels based on this map. I could use the statement: update SegmentParcels set segmentID = [newID] from newsegments where segmentID = currentid but this will create some duplicates I have a unique constraint on ParcelID and SegmentID in SegmentParcels. What is the best way to go about this? I considered removing the constraint and then dealing with removing the duplicates (which I did at one point and could probably do again) but I was hoping there was a simpler way.

  • Update table using SSIS

    - by thursdaysgeek
    I am trying to update a field in a table with data from another table, based on a common key. If it were in straight SQL, it would be something like: Update EHSIT set e.IDMSObjID = s.IDMSObjID from EHSIT e, EHSIDMS s where e.SITENUM = s.SITE_CODE However, the two tables are not in the same database, so I'm trying to use SSIS to do the update. Oh, and the sitenum/site_code are varchar in one and nvarchar in the other, so I'll have to do a data conversion so they'll match. How do I do it? I have a data flow object, with the source as EHSIDMS and the destination as EHSIT. I have a data conversion to convert the unicode to non-unicode. But how do I update based on the match? I've tried with the destination, using a SQL Command as the Data Access mode, but it doesn't appear to have the source table. If I just map the field to be updated, how does it limit it based on fields matching? I'm about to export my source table to Excel or something, and then try inputting from there, although it seems that all that would get me would be to remove the data conversion step. Shouldn't there be an update data task or something? Is it one of those Data Flow transformation tasks, and I'm just not figuring out which it is?

  • Do I have to use Stored Procedures to get query level security or can I still do this with Dynamic S

    - by Peter Smith
    I'm developing an application where I'm concerned about locking down access to the database. I know I can develop stored procedures (and with proper parameter checking) limit a database user to an exact set of queries to execute. It's imperative that no other queries other then the ones I created in the stored procedures be allowed to execute under that user. Ideally even if a hacker gained access to the database connection (which only accepts connections from certain computers) they would only be able to execute the predefined stored procedures. Must I choose stored procedures for this or can I use Dynamic Sql with these fine grain permissions?

  • How to handle Foreign key for optional field in .NET

    - by brz dot net
    What is the best way to handle following situation? A dropdown(for master table) is optional in a particular form. But, In database table the field is constrained with foreign key. If user don't select from dropdown then It creates problem because of foreign key. One solution is to create default option in master table and use it in case of blank selection. but in dropdown, we need to handle this to show on top. Is it perfect solution? Is there any other optimized solution for this? Thanks

  • Select most recent record in sub child

    - by Omar
    I have the following tables/columns: Parent: ParentID Child: ChildID ParentID SubChild: SubChildID ChildID Date Parent has 1 to Many relationship with Child Child has 1 to Many relationship with SubChild For every Parent, I need to get the SubChild with the most recent Date value. How can I do this using SQL. I've tried using MAX(Date), but I can't seem to figure out how to join Parent and Child successfully. The ideal result set would contain all the Parents joined with all the SubChild columns of the latest record. Note: using MS SQL 2005+

  • Recursive CTE with alternating tables

    - by SOfanatic
    I've created a SQL fiddle here. Basically, I have 3 tables BaseTable, Files, and a LinkingTable. The Files table has 3 columns: PK, BaseTableId, RecursiveId (ChildId). What I want to do is find all the children given a BaseTableId (i.e., ParentId). The tricky part is that the way the children are found works like this: Take ParentId 1 and use that to look up a FileId in the Files table, then use that FileId to look for a ChildId in the LinkingTable, if that record exists then use the RecursiveId in the LinkingTable to look for the next FileId in the Files table and so on. This is my CTE so far: with CTE as ( select lt.FileId, lt.RecursiveId, 0 as [level], bt.BaseTableId from BaseTable bt join Files f on bt.BaseTableId = f.BaseTableId join LinkingTable lt on f.FileId = lt.FileId where bt.BaseTableId = @Id UNION ALL select rlt.FileId, rlt.RecursiveId, [level] + 1 as [level], CTE.BaseTableId from CTE --??? and this is where I get lost ... ) A correct output for BaseTableId = 1, should be: FileId|RecursiveId|level|BaseTableId 1 1 0 1 3 2 1 1 4 3 2 1

  • DB Interface Design Optimization: Is it better to optimise for Fewer requests of smaller data size?

    - by Overflow
    The prevailing wisdom in webservices/web requests in general is to design your api such that you use as few requests as possible, and that each request returns therefore as much data as is needed In database design, the accepted wisdom is to design your queries to minimise size over the network, as opposed to minimizing the number of queries. They are both remote calls, so what gives?
