|Hi there
I have a For Loop container which is processing a set of files.
Now there are a certain number of files which will be processed with a
certain file path as follows:
SVPP_ROYA_00001_00021_20200225_01.csv
SVPP_ROYA_00001_00021_20200225_02.csv
SVPP_ROYA_00001_00021_20200225_03.csv
I want to set the property in The Editor for Enumerator Configuration (Files),
so it would be as follows:
SVPP_ROYA_00001_00021_20200225_**.csv
I have a SSIS Variable referred to the above as Dts.Variables["User::FileFullPath"]
How can i set the Files path of the For Loop Enumerator to use my variable [User::FileFullPath]?
Can this be done in Code in a scropt task?
For example
\Package\Foreach Loop Container.Properties[ForEachEnumerator].Files = Dts.Variables["User::FileFullPath"]

You can use an expression to set this property. As shown below, you can use a hard-coded expression to define this. If you already have a variable with this file pattern, you'd substitute that variable instead of the hard-coded expression.

If you're setting the value of the Folder, then define the Expressions options to set the value of the Directory. If you want to set the value of Files, then set use the Expressions to set the value of FileSpec.

Hi Tim
Thanks for you reply
Ok so I can set the property for FileSpec to @[User::FileImportMask] ie SVPP_ROYA_00001_00021_20200225_**.csv
Now I can I loop through and capture each of my file names ] which match the file spec?
SVPP_ROYA_00001_00021_20200225_01.csv
SVPP_ROYA_00001_00021_20200225_02.csv
SVPP_ROYA_00001_00021_20200225_03.csv
What I want to do is to load them into an audit table

That's correct, except that you don't need two asterisks the file spec. A single asterisk will match multiple characters, so you could simply use SVPP_ROYA_00001_00021_20200225_*.csv.

If you want to match a single character, so match the value SVPP_ROYA_00001_00021_20200225_03.csv
but not SVPP_ROYA_00001_00021_20200225_9.csv
or SVPP_ROYA_00001_00021_20200225_100.csv
then use ?
as the wildcard operator, which represents a single character, not many: SVPP_ROYA_00001_00021_20200225_??.csv

As you are loading multiple files, are you concerned about the order in which they are loaded?
