Rename file using File System Task Editor

Could someone please instruct me on how to use the File System Task Editor to rename a file? I place control on control flow tab, change the operation to rename, from there I am not sure what to do.

Create two package variables called FileSource and FileDestination.

Assign the path+existing filename to User::FileSource Variable and assign the path+newfilename to User::FileDestination variable.

In the FileSystemTask properties -
Set Operation to 'Rename File'
Set 'IsSDestinationPathVariable' to True and select 'User::FileDestination' variable for 'DestinationVariable' Parameter.
Set 'IsSourcePathVariable' to True and select 'User::FileSource' variable for 'Sourcevariable' parameter.

When you execute this task - you will find that the source file is renamed as destination file.

Thanks,
Loonysan

|||Please post the exact syntax the destination variable.
I am challenged by something like:
"\\ServerName\DirectoryName\"+DATEPART("yyyy",GETDATE())+DATEPART("mm",GETDATE())+DATEPART("dd",GETDATE())+"_Myfile.txt"|||IanO, Are you using EvaluateAsExpression == True and using the above as an expression instead of the variable value?|||

A slight aside, but if you are writing this file as part of the SSIS package, and just want to create a date stamp named file, then use the expression on the connection string of your flat file connection, and save the extra step of renaming, just create the file with the correct name to start with.

Why are you challenged, the expression itself looked good.

|||Hi Darren, I am trying to do the same thing as you just described, but when I use an expression like:

"C:\Test\Export\CustomFileNamePrefix"+DATEPART("yyyy",GETDATE())+DATEPART("mm",GETDATE())+DATEPART("dd",GETDATE())+".txt"

and place it into the ConnectionString property of my existing Flat File Connector, it errors out when run with the statement that the file name was not valid, even though the directory itself exists and is perfectly valid...

I get similar messages when placing that expression into a variable string (in a File System Task), and setting it to EvaluateAsExpression == True.

What am I missing here please?|||Thanks for your reply, Phil.
Gets or sets a Boolean that indicates that the variable contains an

expression.
That is a nice feature however I'm still looking for a place in one of the dialogs to use it. The examples show its use in code.|||Thanks for your reply, Darren. My challenge is that when I specify new file name, in the connector, it wants to validate that the file already exists. Furthermore, it wants to see columns before I can click OK. So, how do I tell it to give me a connection but not check it at design time? Hasn't this happened to one of you?

Thanks again,
IanO
|||Often you need to use a resource that does not yet exist, be that a file or table. Generally you do need to create the object to help develop the package, but after that you can set the DelayValidation property to prevent errors at run-time. This means that the task does not validate until immediatly prior to executing, rather than at the begining of the overall package execution as well. It is of course assumed that by the time validation does take place any dependencies do then exist.|||I am sorry to ask but where do you create thise package variables?|||

In the variables window. View->Other Windows->Variables|||

Thanks for the help,

I am trying to do a similar task to what eveyone else is doing, basically I created a SSIS by going through the data export wizard where the data I selected gets exported to a flat file.

My package has a data export task that goes to a flat file export task. Based on what Darren spoke of I also created an expression for the default export file name ""DestinationConnectionFlatFile. Then I edited the Connectionstring in expressions and found that none of the sames would work in the posting becuase of the \ escaping issues. I basically used \\\\servers\\share\\filename+DATEPART("yyyy",GETDATE())+DATEPART("mm",GETDATE())+DATEPART("dd",GETDATE())+".txt to see if this would work for me. I am getting the below error stating that I need to cast the last part of the modification where the date is being added on becuase of data type mismatches.

Can someone show me how the expressions should be configured or cast correctly? If I can get one of these working I can get the other date elements coded that I want to use.

Expression:

"\\\\ServerName\\Share\\filename" + DATEPART("yyyy",GETDATE()) +".txt"

Expression cannot be evaluated.

ADDITIONAL INFORMATION:

The data types "DT_WSTR" and "DT_I4" are incompatible for binary operator "+". The operand types could not be implicitly cast into compatible types for the operation. To perform this operation, one or both operands need to be explicitly cast with a cast operator.

Attempt to set the result type of binary operation ""\\\\ServerName\\Share\\filename" + DATEPART("yyyy",GETDATE())" failed with error code 0xC0047080.

valid Expression:

"\\\\ServerName\\Share\\filename" + (DT_WSTR,4)DATEPART("yyyy",GETDATE()) +".txt"

Datepart returns a number. You can't concatenate a number to a string. Instead, you need to cast the number to a string. I have done so for you in the example.|||

Not sure if this is the correct way but it seems to work ok.

"\\\\ServerName\\Share\\filename" + "_" + ((DT_STR,4,1252) DATEPART("yyyy",GETDATE()))

Either way would work...
