COMMA SEPARATED VALUES

Say we have a table #test with columns as follows::

I need to display rows as follows:

We can use FOR XML PATH concept to accomplish this:

QUERY:

First we will create table #test::

CREATE TABLE #test(

field1 VARCHAR(5), field2 VARCHAR(5)

)

Let us first create table #test:

INSERT INTO #test

SELECT '001','AAA'

UNION ALL

SELECT '001','BBB'

UNION ALL

SELECT '002','CCC'

UNION ALL

SELECT '003','DDD'

UNION ALL

SELECT '004','EEE'

UNION ALL

SELECT '004','FFF'

UNION ALL

SELECT '004','GGG'

For required output, the query will be

SELECT field1, SUBSTRING ( (SELECT ( ', ' + field2)

FROM #test t2

WHERE t1.Field1 = t2.Field1

ORDER BY t1.Field1, t2.Field1

FOR XML PATH (' ')), 3, 1000)

FROM #test t1

GROUP BY field1

BIG Data, Hadoop – Chapter 2 - Data Life Cycle

Data Life Cycle The data life cycle is pictorial defined as show below: As we see, in our current system, we capture/ Extract our data, then we store it and later we process for reporting and analytics. But in case of big data, the problem lies in storing and then processing it faster. Hence Hadoop takes this portion, where it stores the data in effective format (Hadoop distributed File System) and also process using its engine (Map Reduce Engine). Since Map Reduce engine or Hadoop engine need data on HDFS format to process, We have favorable tools available in market to do this operation. As an example, Scoop is a tool which converts RDBMS to HDFS. Likewise we have SAP BOD to convert sap system data to HDFS.

How to Copy or Move Multiple Files from One Folder to Another Folder using Talend

Hello all, In this Post, I will explain how to move Multiple Files from One Folder (Say Source) to Other folder (Say Destination). This Post will also helps you to understand How to Declare Variable and Use it. To Declare a variable, We are go to use Contexts option in repository. Lets say we have two .txt files in Path D:/Source/ . My Requirement is to move the files from Source Folder ( D:/Source/ ) to Destination Folder ( D:/Dest/ ). Step 1: Open a New job Step 2: Now right click and Create a New Contexts from Repository. Give some Name and give Next. Step 3: Now Fill in the Source Directory Details where the loop on files should happen as shown in the snippet and give finish. Step 4: Now Context is created and The values will be changing based on each file in Folder. Step 5: Click and Drag the context from Repository to Context Job Window below the Job Designer. Step 6: If we Expand the Contexts, We can find the variable SourcePath is holdi...

How to move multiple files in ssis and also rename simultaneously

There are two ways to achieve this. 1) We can move the flat files and then rename it. 2) While moving files itself, automatic rename should be done. We will do the second type. The criteria is to rename the files while moving from source to destination. So for that, we need FILE SYSTEM TASK to be included. Secondly since we need to move many files, we will use FOR EACH LOOP CONTAINER. To fetch all the files, we can use FOR EACH LOOP task in SSIS. In collection tab, we can select FOREACH FILE enumerator option for fetching files and we can change enumerator configuration Folder option: Points to source where we need to fetch files. Files: will give us idea whether we need to fetch all the files (*.*) or if we give extension like *.txt, it is going to fetch only .txt files . Once I give Source name in FOR EACH LOOP container, It is going to fetch all the files corresponding to that path. Retrieve file name: This option is used to let the variables mentioned in V...
