I have a series of photos on a server with a strict naming convention: "uniqueId-readableName.jpg". I do this because my website database currently only logs the uniqueID (and some unrelated info), but people occasionally need to look at the file server directly to browse the photos (via FTP) so a readable name is useful. For example
001456-War Horse.jpg
003295-Sunshine Daiseys.jpg
129084-Laboring at the farm 2013-08-11.jpg
Now, I'm fairly sure the best option would be to set up the database with a record of the full file names, but I just wanted to see if anyone had any ideas I may have missed. This question on SO is similar, but here I have strict naming conventions - not sure if that opens up any possibilities or not.
I'm applying this to img, but the same idea could be appled to any file extension (eg, download "789-My Homework.zip" or "123-Family vacation.zip").
As an example of what I'm looking for, in Windows Explorer you can do a file search for
0*.jpg
and all of the following files can be returned
001456-War Horse.jpg
003295-Sunshine Daiseys.jpg
029084-Laboring at the farm 2013-08-11.jpg
In my case the beginning part is always unique, so I'd like to use something like 001456-*.jpg and have it return 001456-War Horse.jpg.
Is there any way do this on a website?
<img src="001456-*.jpg" />
Although no such method exists, you can still do a server side scripting to acheive the functionality you require.
For example in PHP you could use in-built commands to browse a folder, select all files matching the criteria name as '001456-*.jpg' and then depending upon the number of records returned select the first filename and insert it into an IMG tag.
Here is a sample implementation in PHP:
$files = array();
$id = "001456";
$files = glob("id-*.jpg");
echo "<img src='$files[0]' />"; //Assuming one file is found for every unique ID.

Imagine I have an external file dates.csv in the following format:
Name
Date
start_of_fin_year
01.03.2022
end_of_fin_year
28.02.2023
Obviously, the file may get updated in the future, and the date may change. I create a piece of code that checks the file periodically to extract needed dates and put them into the DB/variables. Roughly speaking, I have this pseudocode:
start_of_fin_year = SELECT Date FROM table WHERE Name = 'start_of_fin_year'
The problem I face: my code will break if I or someone else changes the name in the table. How do I prevent this?
FYI this is a personal project that I developed on my own, but I will have to give access to .csv files to others so they can update info. I'm afraid they may accidentally change the names, so that's why I'm worried.
we have an access database. We had been using http://www.example.com on various data sections. Now we want to search this URL and replace all occurrences.
I am not sure if Find and Replace utility works in this case. Because Look in field is set to Current Document but my search does not bring expected results.
The goal is only changing domain name so any URL that starts with http://www.example.com will be updated and URLs will start with http://www.newexample.com
One thing that comes to my mind is exporting 40 tables as CSV and doing the operation via Notepad++ and import the resulting CSV file back to database.
In the Find and Replace dialog, make sure that Match is set to Any Part of Field.
I need to upload some 2000 documents to specific users in salesforce. I have a csv file that has the Salesforce-assigned ContactID, as well as a direct path to the files on my desktop. Each contact's specific file url has been included in the csv. How can I upload them all at one and, especially, to the correct contact?
You indicated in the comments / chat that you want it as "Files".
The "Files" object is bit more complex than Attachments, you'll need to do it in 2-3 steps. What you see as a File (you might see it referred to in documentation as Chatter Files or Salesforce Content) is actually several tables. There's
ContentDocument which can be kind of a file header (title, description, language, tags, linkage to many other areas in SF - because it can be standalone, it can be uploaded to certain SF Content Library, it can be linked to Accounts, Contacts, $_GOD knows what else)
ContentVersion which is well, actual payload. Only most recent version is displayed out of the box but if you really want you can go back in time
and more
The crap part is that you can't insert ContentDocument directly (there's no create() call in the list of operations) .
Theory
So you'll need:
Insert ContentVersion (v1 will automatically create for you parent ContentDocuments... it does sound bit ass-backwards but it works). After this is done you'll have a bunch of standalone documents loaded but not linked to any Contacts
Learn the Ids of their parent ContentDocuments
Insert ContentDocumentLink records that will connect Contacts and their PDFs
Practice
This is my C:\stacktest folder. It contains some SF cheat sheet PDFs.
Here's my file for part 1 of the load
Title PathOnClient VersionData
"Lightning Components CheatSheet" "C:\stacktest\SF_LightningComponents_cheatsheet_web.pdf" "C:\stacktest\SF_LightningComponents_cheatsheet_web.pdf"
"Process Automation CheatSheet" "C:\stacktest\SF_Process_Automation_cheatsheet_web.pdf" "C:\stacktest\SF_Process_Automation_cheatsheet_web.pdf"
"Admin CheatSheet" "C:\stacktest\SF_S1-Admin_cheatsheet_web.pdf" "C:\stacktest\SF_S1-Admin_cheatsheet_web.pdf"
"S1 CheatSheet" "C:\stacktest\SF_S1-Developer_cheatsheet_web.pdf" "C:\stacktest\SF_S1-Developer_cheatsheet_web.pdf"
Fire Data Loader, select Insert, select showing all Salesforce objects. Find ContentVersion. Load should be straightforward (if you're hitting memory issues set batch size to something low, even 1 record at a time if really needed).
You'll get back a "success file", it's useless. We don't need the Ids of generated content versions, we need their parents... Fire "Export" in Data Loader, pick all objects again, pick ContentDocument. Use query similar to this:
Select Id, Title, FileType, FileExtension
FROM ContentDocument
WHERE CreatedDate = TODAY AND CreatedBy.FirstName = 'Ethan'
You should see something like this:
"ID","TITLE","FILETYPE","FILEEXTENSION"
"0690g0000048G2MAAU","Lightning Components CheatSheet","PDF","pdf"
"0690g0000048G2NAAU","Process Automation CheatSheet","PDF","pdf"
"0690g0000048G2OAAU","Admin CheatSheet","PDF","pdf"
"0690g0000048G2PAAU","S1 CheatSheet","PDF","pdf"
Use Excel and magic of VLOOKUP or other things like that to link them back by title to Contacts. You wrote you already have a file with Contact Ids and titles so there's hope... Create a file like that:
ContentDocumentId LinkedEntityId ShareType Visibility
0690g0000048G2MAAU 0037000000TWREI V InternalUsers
0690g0000048G2NAAU 0030g000027rQ3z V InternalUsers
0690g0000048G2OAAU 0030g000027rQ3a V InternalUsers
0690g0000048G2PAAU 0030g000027rPz4 V InternalUsers
1st column is the file Id, then contact Id, then some black magic you can read about & change if needed in ContentDocumentLink docs.
Load it as insert to (again, show all objects) ContentDocumentLink.
Woohoo! Beer time.
Your CSV should contain following fields :
- ParentID = Id of object you want to link the attachment to (the ID of the contact)
- Name = name of the file
- ContentType = extension(.xls or .pdf or ...)
- OwnerId = if empty I believe it takes your user as owner
- body = the location on your machine of the file (for instance: C:\SFDC\Files\test.pdf
Use this csv to insert the records (via data loader) into the Attachment object.
You will then see for each contact, that records have been added to the 'Notes & Attachments' related list.
Problem.
I regularly receive a feed files from different suppliers. Although the column names are consistent the problem comes when some suppliers send text files with more or less columns in there feed file.
Furthermore the arrangement of these files are inconsistent.
Other than the Dynamic data flow task provided by Cozy Roc is there another way I could import these files. I am not a C# guru but i am driven torwards using a "Script Task" control flow or "Script Component" Data flow task.
Any suggestion, samples or direction will greatly be appreciated.

Off the top of my head, I have a 50% solution for you.
The problem
SSIS really cares about meta data so variations in it tend to result in exceptions. DTS was far more forgiving in this sense. That strong need for consistent meta data makes use of the Flat File Source troublesome.
Query based solution
If the problem is the component, let's not use it. What I like about this approach is that conceptually, it's the same as querying a table-the order of columns does not matter nor does the presence of extra columns matter.
Variables
I created 3 variables, all of type string: CurrentFileName, InputFolder and Query.
InputFolder is hard wired to the source folder. In my example, it's C:\ssisdata\Kipreal
CurrentFileName is the name of a file. During design time, it was input5columns.csv but that will change at run time.
Query is an expression "SELECT col1, col2, col3, col4, col5 FROM " + #[User::CurrentFilename]
Connection manager
Set up a connection to the input file using the JET OLEDB driver. After creating it as described in the linked article, I renamed it to FileOLEDB and set an expression on the ConnectionManager of "Data Source=" + #[User::InputFolder] + ";Provider=Microsoft.Jet.OLEDB.4.0;Extended Properties=\"text;HDR=Yes;FMT=CSVDelimited;\";"
Control Flow
My Control Flow looks like a Data flow task nested in a Foreach file enumerator
Foreach File Enumerator
My Foreach File enumerator is configured to operate on files. I put an expression on the Directory for #[User::InputFolder] Notice that at this point, if the value of that folder needs to change, it'll correctly be updated in both the Connection Manager and the file enumerator. In "Retrieve file name", instead of the default "Fully Qualified", choose "Name and Extension"
In the Variable Mappings tab, assign the value to our #[User::CurrentFileName] variable
At this point, each iteration of the loop will change the value of the #[User::Query to reflect the current file name.
Data Flow
This is actually the easiest piece. Use an OLE DB source and wire it as indicated.
Use the FileOLEDB connection manager and change the Data Access mode to "SQL Command from variable." Use the #[User::Query] variable in there, click OK and you're ready to work.
Sample data
I created two sample files input5columns.csv and input7columns.csv All of the columns of 5 are in 7 but 7 has them in a different order (col2 is ordinal position 2 and 6). I negated all the values in 7 to make it readily apparent which file is being operated on.
col1,col3,col2,col5,col4
1,3,2,5,4
1111,3333,2222,5555,4444
11,33,22,55,44
111,333,222,555,444
and
col1,col3,col7,col5,col4,col6,col2
-1111,-3333,-7777,-5555,-4444,-6666,-2222
-111,-333,-777,-555,-444,-666,-222
-1,-3,-7,-5,-4,-6,-2
-11,-33,-77,-55,-44,-666,-222
Running the package results in these two screen shots
What's missing
I don't know of a way to tell the query based approach that it's OK if a column doesn't exist. If there's a unique key, I suppose you could define your query to have only the columns that must be there and then perform lookups against the file to try and obtain the columns that ought to be there and not fail the lookup if the column doesn't exist. Pretty kludgey though.
Our solution. We use parent child packages. In the parent pacakge we take the individual client files and transform them to our standard format files then call the child package to process the standard import using the file we created. This only works if the client is consistent in what they send though, if they try to change their format from what they agreed to send us, we return the file.
I'm displaying the contents of a database on a particular page(recipe names).
I'd like each recipe to be a link which opens to another page. I understand I would have to obtain the recipe id for that particular recipe, pass the id to another page and print the recipe contents onto that page. I would like to know how to retrieve the unique recipe id of a particular recipe ON BEING CLICKED upon mainly.
If you are displaying the contents of a database on a particular page, then definitely you are using a server side scripting like like ASP or PHP or some JavaScript + AJAX. I am quite unclear about that. But for your question, I can tell you one thing that, if, suppose you are using PHP, then you may display the link as;
echo ''.$recipiename.'';
where $recipeid is the variable carrying recipe id and $recipiename is the name of your recipe. In your PHP file (yourpage.php), you may catch this data like $_GET["recipeid"]
You may try a Google search for tutorials.
Use;
$strLink = ''.$strName.'';
echo "<li>".$strLink."</li>";
Don't use spaces.
You just make the id part auf the URL the recipe link points to.
Iced Water
Would be a link pointing to the recipe with ID 23. Since the url is available on the server side you are all set.
