To delete file from system you need to use function unlink(). This will delete your file located in assets folder.
Before perform delete query of after query execution you need to pass proper file name into unlink function to delete file from system.
unlink('assets/text.txt');

I am trying to save table as partition using .Q.dpt[hdbroot;.z.d;`tablename].
But it's generating No such file or directory error, but the directory is present.
can you please help me on this.
I have created blank folder to store the data but it's checking for sym file while storing data.
I have created one blank folder and gave that folder path to hdbroot variable, but it's not working.
I could replicate your error by trying to save to a location that doesn't exist on the machine.
q).Q.dpt[`:/does/not/exist;.z.d;`t]
'/does/not/exist/sym. OS reports: No such file or directory
[0] .Q.dpt[`:/does/not/exist;.z.d;`t]
Like I mentioned in my comment, make sure that the hdbroot variable is exactly the location you're expecting. key can help you determine this, here is a quick helper function for you.
q)exists:{"Folder/file ",$[11=abs type key x;"exists";"does not exist"]}
q)exists`:/does/not/exist
"Folder/file does not exist"
q)exists`:/tmp
"Folder/file exists"
I hope you guys keep health and keep strong in Pandemic covid-19.
I have some question on Azure Data Factory. btw I have create some pipeline with Metadata activity with detail below:
I have file in Folder and Subfolder like this:
I have metadata activity with for each with first get metadata child item (in folder) like this:
metadata with last modified like this (if you setting like this, metadata only read last modified subfolder
after that add variable I use #item().Name to read file in that folder like this:
after running metadata which have subfolder, I've get error like this:
the error give info that with #item().Name cannot read subfolder on that folder. the metadata for each file is success, but error like this which on my activity cannot read metadata subfolder .
many big thanks to have answer, Thank You
If you need to access the folder
Create a clone of same dataset and setup parameter as below, leave the file field empty.
If you need to access the file inside directory, use condition #equals(item().type,'Folder') to identity directory then inside that use dataset with parameters for directory and file.
Product CSV created in var folder but it's not getting the download. Or CSV file shows 302 error.

1.expected result: It should download a CSV file

You have to remove deprecated "modules_disable_output" values from core_config_data,
Before run below query please take backup of core_config_data table.
DELETE FROM core_config_data WHERE path LIKE
"advanced/modules_disable_output/%";
And clear cache
Hope it will work for you.
I am trying to upload some files to dropbox using their java API (version 2-beta-4), but some of these files have the same name.
What I would like to know is: What is the reason for I send a file (for instance "file.txt") to dropbox, this file is uploaded, but if I send another file with the same name (file.txt) dropbox overwrite the old file with this new one instead of renaming it to "file (1).txt", even I am setting autorename true and the WriteMode to add?
Code:
DbxRequestConfig config = new DbxRequestConfig("sample", "pt_BR");
String acessToken = "...";
client = new DbxClientV2(config, accessToken);
InputStream input = new ByteArrayInputStream(file.getBytes());
FileMetadata file = client.files.uploadBuilder(path).mode(WriteMode.add).autorename(true)
.mute(true).run(input);
Thanks.
WriteMode.add is what's causing this behavior. "Add" means "Add a new file with this name," so it never overwrites an existing file. If you want to overwrite the existing file, use WriteMode.overwrite.
(Also, isn't it WriteMode.add() and WriteMode.overwrite()? I thought those were methods.)
I started doing development with google scripts few days ago and recently joined stackoverflow. I have a problem with addToFolder() function. I have the following piece of code that copies my new spreadsheet into a folder (test/sheets) in my Google Drive:
var ss = SpreadsheetApp.create("test");
var ssID = ss.getId();
DocsList.getFileById(ssID).addToFolder(DocsList.getFolder("test/sheets"));
My problem is that now I have 2 versions of the same file (one in the root of my Google Drive folder and the other in test/sheets folder), whenever I try to delete either of the copies, the other copy is deleted as well. Is there a way to delete the old file and keep the new one OR is there a way to create the file in the desired folder in first place?
EDIT :
thanks for you quick response. I played with this for couple of hours but still have problem copying the file to the destination folder. The problem is that even when I use makeCopy Method of the file, still addToFolder is the only option to mention the folder. Again this ends up having the tagged filename in the destination folder.
I had the same problem with the copy method.
Here is my new Code:
var SetLocationFile = "icompare/sheets/stocks"
var FolderID = DocsList.getFolder(SetLocationFile);
var FileID = DocsList.getFileById(ssID);
FileID.makeCopy("test3").addToFolder(FolderID);
Folders in Google Docs\Google Drive are actually tags. When you "add" a file to the folder "test/sheets", you do not make a copy of your file, you just attach the tag "test/sheets" to it. Now the same file is shown both in the "test/sheets" folder (i.e. in the list of all files with the tag "test/sheets") and in the root. If you wish to make a copy of the file, you should use the copy method. (Please let me know if I just misunderstand your question.)
I realize this is an old questions but you can simply use .removeFromFolder(DocsList.getRootFolder()); to remove the file from the root folder.
I would also like to know the answer to this question.. seems rather "weird" that the API does not even provide a way to create spreadsheets and place them in a certain map? And no, I do not want a Copy of the file, I want the file to be in a specific map and in no other map...
