问题 Here is the code I currently have that gives me the last 12 days SELECT * FROM table WHERE analysis_date >= current_date - interval '12' day; analysis_date is the date column in the table. I understand why this isn't working because it's not accounting for business days. How can I rewrite this so that I get an interval of the last 12 business days? I tried search online and found extract(dow from (date)) But I couldn't find an example where I need a weekday interval. Any help would be

问题 I am new to Datazen. I have two Datazen Severs for Dev and Production. I want to move the Datazen dashboards from Dev to Production. Can you please let me know how to achieve this. I have checked the CP but didnt find any such option to restore the files. Your help is much appreciated. 回答1: If you are looking for an easy Import/Export..the answer is NOT POSSIBLE. You should be able to use DZ backup & restore Feature to transfer a COMPLETE Server. But this "resets" the targetserver to the

问题 I am running Visual Studio 2010 Ultimate -- which integrates with TFS source control. However, when I run SQL Server 2008 Business Inteligence Studio, no source control is offered. When I look under Tools... Options... Source Control... there are no plug-ins available. Is this because BI Studio uses the 2008 Visual Studio Shell and I only have VS 2010? TIA. 回答1: I think you need to do the following: Install Visual Studio Team Explorer 2008 Install Visual Studio 2008 SP1 Install Visual Studio

问题 I've touched a Teradata. I've never touched hadoop, but since yesterday, I am doing some research on that. By description of both, they seem quite interchangable, but in some papers it is written that they serve for different purposes. But all I found is vague. I am confused. Has anybody experience with both of them? What is the serious difference between them? Simple Example: I want to build ETL which will transform billions rows of raw data and organize them to DWH. Then do some resources

问题 I'm working for a company running a software product based on a MS SQL database server, and through the years I have developed 20-30 quite advanced reports in PHP, taking data directly from the database. This has been very successful, and people are happy with it. But it has some drawbacks: For new changes, it can be quite development intensive The user can't experiment much with the data - it is locked to a hard-coded view It can be slow for big reports I am considering gradually going to a

问题 For more detailed logging, I want to retrieve the [System::TaskName] Right now, when starting from the task that fails we go to 'script task', there I fetch [System::TaskName] and write that in the log. Logically this writes the current TaskName = 'Script task' instead of the failed task Problem is the System::TaskName is only know inside the task, logical... In fact I want to update a variable 'User::CurrentTaskName' from inside the dataflow, = from inside the task. This would be easiest if

问题 I have problems with SSIS process(acctually the same problem occurs for two different processes). So, we are doing some ETL work using SSIS. We have Business Intelligence project that executes without errors from Visual Studio. However when its deployed on the server and scheduled as a job it fails with errors like: INTRASTAT_Towar:Error: SSIS Error Code DTS_E_PROCESSINPUTFAILED. The ProcessInput method on component "Union All 3" (876) failed with error code 0xC0047020 while processing input

问题 Let me first say that being able to take 17 million records from a flat file, pushing to a DB on a remote box and having it take 7 minutes is amazing. SSIS truly is fantastic. But now that I have that data up there, how do I remove duplicates? Better yet, I want to take the flat file, remove the duplicates from the flat file and put them back into another flat file. I am thinking about a: Data Flow Task File source (with an associated file connection) A for loop container A script container
