  • Capturing index operations using a DDL trigger

    - by AaronBertrand
    Today on twitter the following question came up on the #sqlhelp hash tag, from DaveH0ward : Is there a DMV that can tell me the last time an index was rebuilt? SQL 2008 My initial response: I don't believe so, you'd have to be monitoring for that ... perhaps a DDL trigger capturing ALTER_INDEX? Then I remembered that the default trace in SQL Server ( as long as it is enabled ) will capture these events. My follow-up response: You can get it from the default trace, blog post forthcoming So here is...(read more)

  • Hadoop/MapReduce: Reading and writing classes generated from DDL

    - by Dave
    Hi, Can someone walk me though the basic work-flow of reading and writing data with classes generated from DDL? I have defined some struct-like records using DDL. For example: class Customer { ustring FirstName; ustring LastName; ustring CardNo; long LastPurchase; } I've compiled this to get a Customer class and included it into my project. I can easily see how to use this as input and output for mappers and reducers (the generated class implements Writable), but not how to read and write it to file. The JavaDoc for the org.apache.hadoop.record package talks about serializing these records in Binary, CSV or XML format. How do I actually do that? Say my reducer produces IntWritable keys and Customer values. What OutputFormat do I use to write the result in CSV format? What InputFormat would I use to read the resulting files in later, if I wanted to perform analysis over them?

  • An XEvent a Day (31 of 31) – Event Session DDL Events

    - by Jonathan Kehayias
    To close out this month’s series on Extended Events we’ll look at the DDL Events for the Event Session DDL operations, and how those can be used to track changes to Event Sessions and determine all of the possible outputs that could exist from an Extended Event Session.  One of my least favorite quirks about Extended Events is that there is no way to determine the Events and Actions that may exist inside a Target, except to parse all of the the captured data.  Information about the Event...(read more)

  • VBA for Access 2003 - DDL help with creating access file: setting the Autonumber data type

    - by Justin
    So I have the below VB that creates an access file in the default workspace, creates a table, create some fields in that table...just need to know the syntax for setting the first data type/field to autonumber...GUID, Counter, etc will not work as in Access SQL ' error handling usually goes here dim ws as workspace dim dbExample as database dim tblMain as TableDef dim fldMain as Field dim idxMain as Index set ws = workspace(0) set dbExample = ws.CreateDatabase('string file path') set tblMain = dbExample.CreateTableDef("tblMain") set fldMain = tblMain.CreateField("ID", 'right here I do not know what to substitute for dbInteger to get the autonumber type to work ) tblMain.Fields.Append fldMain etc to create other fields and indexes so in this line: set fldMain = tblMain.CreateField("ID", dbInteger) i need to replace the dbInteger with something that VB reconizes as the autonumber property. i have tried GUID, Counter, Autonumber, AutoIncrement....unfortunately none of these work anyone know the syntax I am missing here? Thanks, Justin

  • How to use Nhibernate Validator + NHib component + ddl

    - by mynkow
    I just configured my NHibValidator. My NHibernate creates the DB schema. When I set MaxLenght="20" to some property of a class then in the database the length appears in the database column. I am doing this in the NHibValidator xml file. But the problem is that I have components and cannot figure out how to achieve this behaviour. The component is configured correctly in the Customer.hbm.xml file. EDIT: Well, I found that Hibernate Validator users had the same problem two years ago. http://opensource.atlassian.com/projects/hibernate/browse/HV-25 Is this an issue for NHibernate Validator or it is fixed. If it is working tell me how please. ----------------------------------------------------- public class Customer { public virtual string Name{get;set;} public virtual Contact Contacts{ get; } } ----------------------------------------------------- public class Contact { public virtual string Address{get;set;} } ----------------------------------------------------- <?xml version="1.0" encoding="utf-8" ?> <nhv-mapping xmlns="urn:nhibernate-validator-1.0" namespace="MyNamespace" assembly="MyAssembly"> <class name="Customer"> <property name="Name"> <length max="20"/> </property> <property name="Contacts"> <notNull/> <valid/> </property> </class> </nhv-mapping> ----------------------------------------------------- <?xml version="1.0" encoding="utf-8" ?> <nhv-mapping xmlns="urn:nhibernate-validator-1.0" namespace="MyNamespace" assembly="MyAssembly"> <class name="Contact"> <property name="Address"> <length max="50"/> <valid/> </property> </class> </nhv-mapping> -----------------------------------------------------

  • Finding Stuff in SQL Server Database DDL

    You'd have thought that nothing would be easier than using SQL Server Management Studio (SSMS) for searching through the DDL for both the names and definitions of the structural metadata of your databases, for the occurrence of a particular string of letters. Not so easy, it turns out, though Phil Factor is able to come up with various methods for various purposes.

  • How should I migrate DDL changes from one environment to the next?

    - by Rl
    I make DDL changes using SQL Developer's GUI. Problem is, I need to apply those same changes to the test environment. I'm wondering how others handle this issue. Currently I'm having to manually write ALTER statements to bring the test environment into alignment with the development environment, but this is prone to error (doing the same thing twice). In cases where there's no important data in the test environment I usually just blow everything away, export the DDL scripts from dev and run them from scratch in test. I know there are triggers that can store each DDL change, but this is a heavily shared environment and I would like to avoid that if possible. Maybe I should just write the DDL stuff manually rather than using the GUI?

  • How to Generate a Create Table DDL Script Along With Its Related Tables

    - by Compudicted
    Have you ever wondered when creating table diagrams in SQL Server Management Studio (SSMS) how slickly you can add related tables to it by just right-clicking on the interesting table name? Have you also ever needed to script those related tables including the master one? And you discovered you have dozens of related tables? Or may be no SSMS at your disposal? That was me one day. Well, creativity to the rescue! I Binged and Googled around until I found more or less what I wanted, but it was all involving T-SQL, yeah, a long and convoluted CROSS APPLYs, then I saw a PowerShell solution that I quickly adopted to my needs (I am not referencing any particular author because it was a mashup): 1: ########################################################################################################### 2: # Created by: Arthur Zubarev on Oct 14, 2012 # 3: # Synopsys: Generate file containing the root table CREATE (DDL) script along with all its related tables # 4: ########################################################################################################### 5:   6: [System.Reflection.Assembly]::LoadWithPartialName('Microsoft.SqlServer.SMO') | out-null 7:   8: $RootTableName = "TableName" # The table name, no schema name needed 9:   10: $srv = new-Object Microsoft.SqlServer.Management.Smo.Server("TargetSQLServerName") 11: $conContext = $srv.ConnectionContext 12: $conContext.LoginSecure = $True 13: # In case the integrated security is not used uncomment below 14: #$conContext.Login = "sa" 15: #$conContext.Password = "sapassword" 16: $db = New-Object Microsoft.SqlServer.Management.Smo.Database 17: $db = $srv.Databases.Item("TargetDatabase") 18:   19: $scrp = New-Object Microsoft.SqlServer.Management.Smo.Scripter($srv) 20: $scrp.Options.NoFileGroup = $True 21: $scrp.Options.AppendToFile = $False 22: $scrp.Options.ClusteredIndexes = $False 23: $scrp.Options.DriAll = $False 24: $scrp.Options.ScriptDrops = $False 25: $scrp.Options.IncludeHeaders = $True 26: $scrp.Options.ToFileOnly = $True 27: $scrp.Options.Indexes = $False 28: $scrp.Options.WithDependencies = $True 29: $scrp.Options.FileName = 'C:\TEMP\TargetFileName.SQL' 30:   31: $smoObjects = New-Object Microsoft.SqlServer.Management.Smo.UrnCollection 32: Foreach ($tb in $db.Tables) 33: { 34: Write-Host -foregroundcolor yellow "Table name being processed" $tb.Name 35: 36: If ($tb.IsSystemObject -eq $FALSE -and $tb.Name -eq $RootTableName) # feel free to customize the selection condition 37: { 38: Write-Host -foregroundcolor magenta $tb.Name "table and its related tables added to be scripted." 39: $smoObjects.Add($tb.Urn) 40: } 41: } 42:   43: # The actual act of scripting 44: $sc = $scrp.Script($smoObjects) 45:   46: Write-host -foregroundcolor green $RootTableName "and its related tables have been scripted to the target file."

  • Auditing DDL Changes in SQL Server databases

    Even where Source Control isn't being used by developers, it is still possible to automate the process of tracking the changes being made to a database and put those into Source Control, in order to track what changed and when. You can even get an email alert when it happens. With suitable scripting, you can even do it if you don't have direct access to the live database. Grant shows how easy this is with SQL Compare.

  • Is there a declarative language for data definitions?

    - by Jekke
    Reading about WPF and thinking about my application's data store at the same time led me to wonder if there are any languages or tools that allow you to define relational data in a declarative way? A shallow Google search suggests no such thing exists. Yet it seems so obviously useful. The kind of tool I have in mind would declaratively describe (at least) entities, relationships and views is a platform-agnostic way that would act as an abstraction layer between data-driven applications and their datastores. Does any such tool exist?

  • Dolby Digital Live (DDL) on Asus Rampage II Gene (Creative X-Fi Extreme)

    - by kevyn
    Hi there, I have an Asus Rampage II Gene motherboard which has X-Fi extreme built in. I can get it to work with Windows 7 ok using the Creative drivers, however when I try and install the DDL/DTS add on pack from Creative I get the error message: "There are no supported audio device available. You need to close the application. Click OK to close the application now" I don't understand it because I have the Creative software installed ok and supporting the sound without any problems. In Device manager the audio device comes up as 'High definition audio device' and uses driver: 6.1.7600.16385 from Microsoft. I tried using the Creative drivers which show up as 'soundmax HD audio' however these do not allow any of the Creative products to run properly. Please can anyone offer any help? Or even just confirm that DDL can work with my onboard sound? Windows 7 Ultimate 64 bit 6GB DDR3 XFX GS8800 384mb Asus Rampage II Gene Intel i7 920 (2.66)

  • Manually insert items into DDL after data binding...

    - by WeeShian
    I have a dropdownlist, which dynamically populate data from SQL Server and i wanna manually insert two items on top of the DDL after data binding. So, the DDL would has data something like this: Select Branch (manually insert) ALL (manually insert) AIR AMP ABG ... I tried to achieve it by using code below: ddlBranch.Items.Insert(0, "Select Branch") ddlBranch.Items(0).Value = CMM.sExcVal1 ddlBranch.Items.Insert(1, "ALL") ddlBranch.Items(1).Value = "ALL" but it comes out giving me the data like this: Select Branch (manually insert) ALL (manually insert) ('AIR' branch should be here but it's gone) AMP ABG ... After manually insert the 'ALL' item into the DDL, the 'AIR' is gone which is already replaced by the 'ALL'. How can i remain all the data from server and at the same time i can manually insert two items?

  • Custom DDL Templates for Visual Studio 2010

    - by Stacey
    I was wondering if anyone knows of some good community distributed custom DDL templates for Entity Framework 4.0. The default DDL to SQL10 Works well enough, but we're looking to do some customization to the naming convention that it just isn't offering us. I'm not really finding many samples out there of people doing this, so I was hoping someone might know of a resource I'm overlooking (perhaps I am searching for it wrong, or misunderstanding how the whole process works) Specifically we're wanting to change up how it writes out fields from relationships. For instance, the default template puts in.. tablename_propertyendpoint_propertyname. We're wanting to find tune this to our naming scheme a little more. And none of us can quite figure out where in the .tt files it is doing this exact behavior.

  • How to return DropDownList selections dynamically in C#?

    - by salvationishere
    This is probably a simple question but I am developing a web app in C# with DropDownList. Currently it is working for just one DropDownList. But now that I modified the code so that number of DropDownLists that should appear is dynamic, it gives me error; "The name 'ddl' does not exist in the current context." The reason for this error is that there a multiple instances of 'ddl' = number of counters. So how do I instead return more than one 'ddl'? Like what return type should this method have instead? And how do I return these values? Reason I need it dynamic is I need to create one DropDownList for each column in whatever Adventureworks table they select. private DropDownList CreateDropDownLists() { for (int counter = 0; counter < NumberOfControls; counter++) { DropDownList ddl = new DropDownList(); SqlDataReader dr2 = ADONET_methods.DisplayTableColumns(targettable); ddl.ID = "DropDownListID" + (counter + 1).ToString(); int NumControls = targettable.Length; DataTable dt = new DataTable(); dt.Load(dr2); ddl.DataValueField = "COLUMN_NAME"; ddl.DataTextField = "COLUMN_NAME"; ddl.DataSource = dt; ddl.ID = "DropDownListID 1"; ddl.SelectedIndexChanged += new EventHandler(ddlList_SelectedIndexChanged); ddl.DataBind(); ddl.AutoPostBack = true; ddl.EnableViewState = true; //Preserves View State info on Postbacks //ddlList.Style["position"] = "absolute"; //ddl.Style["top"] = 80 + "px"; //ddl.Style["left"] = 0 + "px"; dr2.Close(); } return ddl; }

  • WinPcap/Wireshark install: where is packet.ddl?

    - by Annonomus Penguin
    I have Wireshark installed, and I'm getting this error: The NPF driver isn't running. You may have trouble capturing or listing interfaces. I realize this is something to do with WinPcap. It's not in control panel, as the FAQ states it should be. I've tried installing it, and it says that there is a previous version installed. This leaves me to believe this is the problem: To be absolutely sure that WinPcap has been installed, please look at your system folder: you should find files called packet.* and wpcap.dll. Please check the file dates: these should be compatible with the WinPcap release dates. We've had reports of trojans or other malware that silently install the WinPcap driver, NPF.sys. If you've been infected by them, you'll probably see the driver file in Windows\System32\Drivers, but no entries in the "Add or Remove Programs" applet and no dlls. I've searched my hard drive, but the only path is this: C:\Windows\SysWOW64\packet.dll Is this the file they are talking about? Should I delete this file? I'm not quite sure, so I thought I'd verify that this file is the right one.

  • table changes depending on ddl values with servlet

    - by kawtousse
    I will be more clear. What I want to realize is the following: In a JSP x I have a 3 dropdownlists and a button called edit when user click this button a table dynamically should be displayed. Now this table is modified correponding the values in those 3 ddl. So it can be 3 cols or 4 cols or even 6 cols it depends on the selected values. So what I tried is to use the servlet to getParameter doing the if clause construct the html and then forward the response.Have you any the suggestion of the structure that I can use. Think you.

  • UpdateModel not working consistently for me if a ddl gets hidden by jQuery

    - by awrigley
    Hi My jQuery code hides a ddl under certain circumstances. When this is the case, after submitting the form, using the UpdateModel doesn't seem to work consistently. My code in the controller: // POST: /IllnessDetail/Edit [AcceptVerbs(HttpVerbs.Post)] public ActionResult Edit(IllnessDetail ill) { IllnessDetailFormViewModel mfv = new IllnessDetailFormViewModel(ill); if (ModelState.IsValid) { try { IllnessDetail sick = idr.GetLatestIllnessDetailByUsername(User.Identity.Name); UpdateModel(sick); idr.Save(); return RedirectToAction("Current", "IllnessDetail"); } catch { ModelState.AddRuleViolations(mfv.IllnessDetail.GetRuleViolations()); } } return View(new IllnessDetailFormViewModel(ill)); } I have only just started with MVC, and working under a deadline, so am still hazy as to how UpdateModel works. Debugging seems to reveal that the correct value is passed in to the action method: public ActionResult Edit(IllnessDetail ill) And the correct value is put into sick in the following line: IllnessDetailFormViewModel mfv = new IllnessDetailFormViewModel(ill); However, when all is said, done and returned to the client, what displays is the value of: sick.IdInfectiousAgent instead of the value of: ill.IdInfectiousAgent The only reason I can think of is that the ddlInfectiousAgent has been hidden by jQuery. Or am I barking up the wrong lamp post? Andrew

  • MySQL DDL error creating tables

    - by Alexandstein
    I am attempting to create tables for a MySQL database, but I am having some syntactical issues. It would seem that syntax checking is behaving differently between tables for some reason. While I've gotten all the other tables to go through, the table, 'stock' doesn't seem to be working, despite seeming to use the same syntax patterns. CREATE TABLE users ( user_id SMALLINT UNSIGNED NOT NULL AUTO_INCREMENT, username VARCHAR(30) NOT NULL, password CHAR(41) NOT NULL, date_joined DATETIME NOT NULL, funds DOUBLE UNSIGNED NOT NULL, PRIMARY KEY(user_id), UNIQUE KEY(username) ); CREATE TABLE owned_stocks ( id SMALLINT UNSIGNED NOT NULL AUTO_INCREMENT, user_id SMALLINT UNSIGNED NOT NULL, paid_price DOUBLE UNSIGNED NOT NULL, quantity MEDIUMINT UNSIGNED NOT NULL, purchase_date DATETIME NOT NULL, PRIMARY KEY(id) ); CREATE TABLE tracking_stocks ( ticker VARCHAR(5) NOT NULL, user_id SMALLINT UNSIGNED NOT NULL, PRIMARY KEY(ticker) ); CREATE TABLE stocks ( ticker VARCHAR(5) NOT NULL, last DOUBLE UNSIGNED NOT NULL, high DOUBLE UNSIGNED NOT NULL, low DOUBLE UNSIGNED NOT NULL, company_name VARCHAR(30) NOT NULL, last_updated INT UNSIGNED NOT NULL, change DOUBLE NOT NULL, percent_change DOUBLE NOT NULL, PRIMARY KEY(ticker) ); Am I just missing a really obvious syntactical issue?
