问题 I have a table with a VARBINARY(MAX) field (SQL Server 2008 with FILESTREAM ) My requirement is that when I go to deploy to production, I can only supply my IT team with a group of SQL scripts to be executed in a certain order. A new table I am making in production has this VARBINARY(MAX) field. Usually with new tables, I will script out the CREATE TABLE script. And, if I have data I need to go with it, I will then script out the INSERT scripts. Not too complicated. But with VARBINARY(MAX) ,

Controlling file extension when inserting data into SQL Filestream column?

问题 I have a SQL Server Express database with a 10gig limit, so I'm trying to save space by moving a big text column over to a FileStream type. I created a new database, set up FileStreaming as well as the FileStream column and set it up as a full text index. Then I tried inserting data into the new database from my other database (insert column to column). The resulting FileStream files are being created with no file extension (which I guess is to be expected). I think this is causing my full

Stream an (SqlFile-)Stream using Nancy

问题 I was wondering how to send an (in my case) SqlFileStream directly to the client through our Nancy-API without loading the stream in memory. So far I succeeded in passing the stream, but Nancy's StreamResponse copies the sourcestream (=SqlFileStream) to the outputstream which causes a massive memory increase. Where I would just like it to send the stream through. I made this work in WebApi where WebApi was registered in the Owin-pipeline. No memory increase is noticeable, which is great when

问题 I am extracting content of the Files in SQL File Table. The following code works if I do not use Parallel. I am getting the following exception, when reading sql file stream simultaneously (Parallel). The process cannot access the file specified because it has been opened in another transaction. TL;DR: When reading a file from FileTable (using GET_FILESTREAM_TRANSACTION_CONTEXT) in a Parallel.ForEach I get the above exception. Sample Code for you to try out: https://gist.github.com/NerdPad

SQL Server 2008 FILESTREAM performance

由 寵の児 提交于 2019-12-03 07:10:17
问题 I had some questions around the FILESTREAM capability of SQL Server 2008. What would the difference in performance be of returning a file streamed from SQL Server 2008 using the FILESTREAM capability vs. directly accessing the file from a shared directory? If 100 users requested 100 100Mb files (stored via FILESTREAM) within a 10 second window, would SQL Server 2008 performance slow to a crawl? 回答1: If 100 users requested 100 100Mb files (stored via FILESTREAM) within a 10 second window,
