GOTO COMMAND AND LABELS IN T-SQL.. EXAMPLE WITH A STORED PROEDURE!!!!!!!!


CREATE PROCEDURE NUV
@TEST NVARCHAR(100)
AS BEGIN

IF @TEST='DHINAKARAN' GOTO DHINAKARAN --JUMPS TO DHINAKARAN LABEL.
IF @TEST='BHARATH' GOTO BHARATH -- JUMPS TO LABEL NAMED BHARATH
IF @TEST='JOB' GOTO JOB -- JUMPS TO LABEL NAMED JOB

DHINAKARAN:--LABEL DECLARATION AND ITS FOLLOWING COMMAND
PRINT 'DHINAKARAN IS A ASSOCIATE ETL DEVELOPER 
AT NUVENTO SYSTEMS PVT LTD JOINED IN 2011, NOVEMBER'

GOTO FINISH -- THIS IS USED TO PREVENT LABEL BHARATH WHICH IS BELOW FROM EXECUTING

BHARATH: 
PRINT 'BHARATH IS A SNR ETL DEVELOPER AT NUVENTO SYSTEMS JOINED IN 2009, MARCH'

GOTO FINISH -- THIS IS USED TO PREVENT LABEL JOB WHICH IS BELOW FROM EXECUTING

JOB: PRINT 'JOB IS A ETL DEVELOPER AT  NUVENTO SYSTEMS JOINED IN 2010, JULY'

GOTO FINISH

FINISH:
END

After running this stored procedure, if we try to execute with either of the name mentioned above like bharath, dhinakaran, job, you will get printed version which is mentioned in label.

Example and its snippet is shown below.

If we give EXEC NUV 'DHINAKARAN', Then output will be  "DHINAKARAN IS A ASSOCIATE ETL DEVELOPER 
AT NUVENTO SYSTEMS PVT LTD JOINED IN 2011, NOVEMBER"

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.
