We want to use the same package to export the objects into the destination folder as well. In the previous article, Importing SQL Server FILESTREAM data with SSIS packages, we created an SSIS package to import the files into SQL Server FILESTREAM tables. Use an SSIS package to Import and Export FILESTREAM objects Therefore, you can see the icon image of each file type as well. You can open the files, and OS recognize these files. Below you can the files are now present in this folder with the actual file name and the extension. We can verify the files from the destination folder. Once the script completes the files export from FILESTREAM container, you get the message ‘Finished’. You get the printed message in the PowerShell window for each file that is copied to the folder.
Script execution may take time depending upon the number of objects, their size, network bandwidth. It will start copying the files from the SQL Server FILESTREAM to the desired folder specified in the script.

Launch the Windows PowerShell from the start menu. The complete script to copy the SQL Server FILESTREAM data into file system is as below. Note: You need to change the connection parameters and the destination folder path as per your requirement before executing the script. Now let us combine all parts of the script in a single file. Read - Host - Prompt "Press Enter to exit" We also need to define the buffer size, let us define is as 16,384 bytes. In the following command, you will notice the SQL Server instance details, database name in which FILESTREAM table exists, destination folder. I have taken this script from Microsoft TechNet and modified it as per our requirement.ĭefine the parameters for connection to SQL Server: In this part, we will define the variable and pass the required input. Once we have covered the script, we will use the combined script to export the objects in Windows PowerShell. To fully understand this step, we need to review the PowerShell script in parts. We can use PowerShell to interact with the SQL Server FILESTREAM and export the objects into the destination folder. PowerShell is a very powerful management tool that can interact with SQL Server easily and do administrative tasks with minimal configurations.
RAZORSQL IMPORT CSV HOW TO
In this article, we want to demonstrate how to export the images as per the following sources and destinations. Further complicating things, it is difficult to identify the file type because it does not have any file extension.
It does not open in the correct format because it is an image file. We do not necessarily know the appropriate type of this file, therefore let us open with the Notepad. If we try to open it, it asks us to select the program in which we want to open the file. Once we have copied the files into a different drive, we’ll try to open it, but the OS does not recognize the extension of these files. We copied the above-highlighted objects into different drive.
Let us say we just want to copy few files from SQL Server FILESTREAM container to local disk. Instead, it assigns the names as per an internal mechanism. SQL Server does not store the files in their original name. First, we do not know the exact name of the files. Suppose we have the following files stored in the SQL Server FILESTREAM container. Let us first look at the issues with this approach. Even though you might think that we can copy the files directly by accessing the file system. We might need to copy the complete data or particular data from the file system. Sometimes, we want to export FILESTREAM objects to different drive. In my previous article, Importing SQL Server FILESTREAM data with SSIS packages, we used SSIS packages to import the files into SQL Server FILESTREAM table. It is faster and provides better IO in comparison with the traditional file system. If we have a large number of objects in the file system, it is advisable to use the fast disk for storage purpose.
RAZORSQL IMPORT CSV SERIES
In this series of articles on SQL Server FILESTREAM (see TOC at bottom), we explored various ways to store unstructured data in the file system with the metadata in SQL Server tables.
