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"

Zip/Unzip multiple files and also include password for zipped file using SSIS

We have many scenario that we need to Zip many files which we come across and then so some operations like either sending it as a email or just moving zipped file to some other destinations etc. But we were using manual method to zip multiple files. In this post, I tried to create a package which will zip multiple files using SSIS. Here for Zipping files purpose, I'm using 7-ZIP which is free software available in google sites. Download files and install onto your system. First let me show how to Zip on file and later I will show how to zip multiple files using SSIS and 7Zip tool. Compressing Single file. Here I'm trying to Zip one single flat file which is of 40MB size. I kept this file in C:\Documents and Settings\\Desktop\test\source folder. Now to compress this file, I will open my SSIS and I'm dragging and dropping EXECUTE PROCESS TASK from Control Flow. Now right click on Execute Process task and go for edit and select Process option. In process tab,

SSIS: The Value Was Too Large To Fit In The Output Column

I had a SSIS package where I was calling a stored procedure in OLEDB Source and it was returning a “The Value Was Too Large to Fit in the Output Column” error. Well, My Datatype in OLEDB source was matching with my OLEDB Destination table. However, when I googled, we got solutions like to increase the output of OLEDB Source using Advanced Editor option . I was not at all comfortable with their solution as my source, destination and my intermediate transformation all are having same length and data type and I don’t want to change. Then I found that I was missing SET NOCOUNT ON option was missing in Stored Procedure. Once I added it, my data flow task ran successfully.

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 VARIA
