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.

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...
