Azure Data Factories vs SSIS

空扰寡人 提交于 2020-03-18 05:26:07
问题 I am thinking of moving our SSIS ETLs to Azure Data Factory. My arguments in favour of such leap are: Our sources and targets are already in the cloud. ADF is cloud native so it seems at good fit. ADF is a service are therefore we could consume and pay for it on demand. SSIS implies licensing costs, and doesn't lend lend it itself naturally for on-demand consumption (we thought of using DevOps to spin ETL servers on an ad-hoc basis) Generating ETL code programmatically with SSIS requires very

问题 I am exporting Data from SQL Server to Excel, utilizing SSIS Data Flow Task. Here all columns appear as Text despite export formatting. Hence I need to develop a SSIS Script task to do the necessary conversion. I am facing trouble in developing the script. Excel Workbook before Formatting See, the Excel Cell has no Apostrophe and the Number type is also "General" but the message says The number in this cell is formatted as text or preceded by an apostrophe I have Tried different options

效率最高的Excel数据导入---(c#调用SSIS Package将数据库数据导入到Excel文件中【附源代码下载】)

本文目录: (一)背景 (二)数据库数据导入到Excel的方法比较 (三)SSIS的简介 (四)数据库中存储过程示例(SSIS应用需要) (五)Excel模板的制作(这步这么简单,稍微介绍一下) (六)SSIS操作过程(生成Package,用来调用)(下一篇随笔将详细讲解制作Package包的过程,图片太多,篇幅过长,因此本文将直接采用生成的Package包进行应用) (七)C#中如何调用 SSIS创建的Package和 Excel模板(可以自己编写逻辑代码进行重复利用), 用来生成Excel数据 (八)总结 (一)背景 如何将数据库中的数据导入到EXCEL文件中,我们经常会碰到。本文将比较常用的几种方法,并且将详细讲解基于SSIS的用法。笔者认为,基于SSIS的方法,对于海量数据来说,应该是效率最好的一种方法。个人认为,这是一种值得推荐的方法,因此,本人决定将本人所知道的、以及自己总结的完整的写出来,一是提高一下自己的写作以及表达能力,二是让更多的读者能够在具体的应用中如何解决将海量数据导入到Excel中的效率问题。 (二)方法的比较 方案一:SSIS(SQL Server数据集成服务),追求效率,Package制作过程复杂一点(容易出错)。 方案二:采用COM.Excel组件。一般,对于操作能够基本满足,但对于数据量大时可能会慢点。下面的代码,本人稍微修改了下,如下所示

Can a SSIS 2012 package be deployed to SQL Server 2008 R2?

天涯浪子 提交于 2020-03-09 05:24:49
问题 I built a SSIS package in VS2013 and can't find any deployment instructions. One person mentioned he thought you can't deploy backwards. So before I rebuild the package in BIDS 2008, I want to make sure there is no way to deploy. 回答1: Pretty much none of the MS BI stack (SSIS, SSRS, SSAS) is backward compatible, meaning you cannot develop in a newer environment and deploy to an older SQL Server. And if you think about it, it's easy to understand why: SSIS packages, SSRS Reports, and SSAS

SSIS 连接数据

通常情况下,ETL方案需要同时访问两个或多个数据源,并把结果合并为单个数据流,输出到目标表中。为了向目标表中提供统一的数据结构,需要把多个数据源连接在一起。数据连接的另外一种用法,就是根据现有的数据,向目标表中添加数据,或者更新现有的数据。这种方案是把源数据与现有的数据进行比较,以便找到需要更新的数据行,或者需要添加的数据。在设计ETL方案时,连接数据可以使用SSIS的转换(Lookup和Merge Join)组件,或者直接在关系型数据库内部执行,而后者性能更高。 一,SSIS 连接 查找转换以嵌套循环(Nested Loop)的方式实现连接操作,该组件被设计为以同步方式进行连接操作,这意味着在进行转换的时候,查找转换不会阻塞数据流管道,但是,在全缓存(Full Cache)模式下,当组件加载查找数据集的内部缓存时,可能会阻塞包一段时间,阻塞时间的长短由加载查找数据集的时间来决定。 合并连接(Merge Join)转换也可以实现连接操作,通常情况下,它比查找转换更适合做连接操作,转换的性能更高。相比查找转换,合并连接对输入数据的要求更严格: 两个输入的数据必须是有序的 ; 设置连接类型 ,Merge Join支持Inner Join,Left Join和Full Join三种连接类型; 设置比较列的映射,Merge Join只支持等值连接,自动按照排序列设置比较列的映射;

【SSIS】Foreach循环容器读取 xlsm 格式的文件时,连接管理器出错

Foreach循环容器读取 xlsm 格式的文件时,连接管理器出错,错误如下 因为读取文件的初始路径配置成了 .xlsm 格式 将xlsm格式改成 .xlsx 格式 然后重新将数据流里的Excel数据源重新配置一下,并把数据源的这个属性改为False,重新运行就成功了 来源: https://www.cnblogs.com/crazy-zjl/p/12422633.html

SSIS For Loop Container with Date Variable

问题 I want to create a monthly package that executes a daily query at ODBC and writes an output file. More specifically the query must be first executed for the first day of the previous month (e.g. '01/11/2018') then the next one ('02/11/2018') until the last day of the previous month ('30/11/2018') . The date variables are currently saved as Strings and I also want to have a string variable with Oracle date format to be inserted into the query. How should it be organised? Is there a way that I
