which command will give the current date?

My requirement is i have to add the current date at the end of the file.

if i run today then today's date, if i run tomorrow then tomorrow's date.

use a move command in ExecDOS where the second parameter should be
hope this helps.

1) I have declared a variable in the Parameter like

Parameter DefaultValue
FileName MSDFF

2) I choosed 'ExecDOS' from after subroutine(Transformer stage).

3) I gave the below value in the INPUT VALUE combo box.

MOVE #FileName# MSDFF%date:~6,4%%date:~3,2%%date:~0,2%.txt

is this correct?

I got the below error message.

ALRT_A01..tr_xc (ExecDOS): Error when executing command: MOVE MSDFF MSDFF%date:~6,4%%date:~3,2%%date:~0,2%.txt
*** Output from command was: ***
The syntax of the command is incorrect.

Try something like


where pCurrentDate is the date parameter formatted in required manner.

First off, you need to do it after job not after stage. Secondly, you need a valid DOS command for the task - use rename rather than move. Get it working from a cmd prompt then add it to the job.

I cannot test it from datastage job as I am on unix box. But on command prompt
MOVE MSDFF MSDFF%date:~6,4%%date:~3,2%%date:~0,2%.txt
works fine and a file called MSDFF20090702.txt got created.

if by any chance datastage is not allowing it to execute, create a job parameter pCurrentDate and from sequence job you can pass formatted date using combination of Date() and field() function.

and execute a rename command in after job ExecDOS using this parameter similar to Sainath's suggestion with Craig's suggestion implemented in it. something like

rename yourFileName yourFileName#pCurrentDate#

Technically, 'move' is for moving a file from one drive letter / location to another and 'rename' just renames a file in place. With a UNIX background you might gravitate to 'move' but 'rename' would be more appropriate even if the other can be made to work.

@Craig

I agree.

@karthi_gana

Just noticed : where is the path?

you need to provide a fully qualified path of the file to run the command. Computer is not so intelligent to find that file for you before renaming or moving it.
