I have migrated MySQL DB to MongoDB, and my blob file stored was converted to binary in this way.
enter image description here
Now how i can have access on this file and open it?

I have created a data flow within Azure synapse to:
take data from a dedicated SQL pool
perform some transformations
send the resulting output to parquet files
I am then creating a View based on the resulting parquet file using OPENROWSET to allow PowerBI to use the data via the built-in serverless SQL pool
My issue is that whatever the file name I enter on the integration record, the parquet files always look like part-00000-2a6168ba-6442-46d2-99e4-1f92bdbd7d86-c000.snappy.parquet - or similar
Is there a way to have a fixed filename which is updated each time the pipeline is run, or alternatively is there a way to update the parquet file to which the View refers each time the pipeline is run, in an automated way.
Fairly new to this kind of integration, so if there is a better way to acheive this whole thing then please let me know
Azure Synapse Data Flows - parquet file names not working
I repro'd the same and got the file name as in below image.
In order to have the fixed name for sink file name,
Set Sink settings as follows
File name Option: Output to single file
Output to single file: tgtfile (give the file name)
In optimize, Select single partition.
Filename is as per the settings
I'm working on a POC to save a file (binary) into SQL Server database.
The Laravel documentation don't have anything related to saving binary to database using Eloquent.
As mentioned in comments, it's not a proper way to save files in database but still you can. First add binary column to your model's migration:
$table->binary('bfile');
This will make a BLOB field in database.
Then just read contents of that file and store it in model:
$model = new SampleModel();
$model->bfile = $contents;
$model->save()
I'm planning to write a ASP.NET MVC app that will upload large files (possibly as large as 500 MB) to a SQL Server 2014 FileTable. Is there some way to check if the file already exists in the FileTable before uploading?
If the file already exists in the database, then I will want to reference the already-uploaded file instead of uploading a new one.
If the file must first be uploaded to the FileTable before checking whether the file already exists in the FileTable, what's the recommended way to do the comparison? (Should I do some sort of separate CRC generated for each file and then compare against that?)
Thanks!
You will have to calculate the hash of the file on the client side before uploading it. I don't have the pieces of code, only the concepts:
using the HTML File API, and the File Reader to read the file
with a Javascript implementation of SHA256 compute the hash of the file
on your server you store the file contents, as well as the SHA256 hash of each file
client performs an AJAX request to see if the a file with this hash already exists
if it doesn't already exist: Upload it!
Is there a way in sybase where I can select (read) an image or a file from the a server or driver ?
In oracle there is Bfile , it lets me to read an image directly from the driver, how to do that in sybase ?.
You can read/write text files located on the ASE server's host through a proxy table that is mapped to a file.
Unfortunately, there is no way to read a binary file like an image via such a proxy table or otherwise directly from SQL. Some kludges are possible though:
you can use BCP and a format file to read a binary file into an image column (see my Tips & Tricks book below), and you can run this from SQL via xp_cmdshell.
you can use the Java JVM that is embedded in the ASE server to read files and move the content into a table; that will require combined Java and SQL programming. YMMV.
I am writing an add-on to a current system and need to get image data. However the image data gets saved in a directory on the server side of the client/server application. I want to read the file from the directory and return it as an image field using SQL Server which is also on the Server.
Is this at all possible?
Write a CLR storedprocedure (c#) which reads the contents of the image file and returns it as a varbinary(MAX).
