Question

I’m trying to create an assembly but my remote sql server cannot access my .dll file.

create assembly BarcodeSql 
from 'X:\test.dll' 
WITH PERMISSION_SET = SAFE

I don’t know how to put test.dll on my sql server, but I know I can send a serialized dll instead of the path to the dll. How can I serialize the dll? I can’t seem to figure it out.

Answer 1

I’m trying to create an assembly but my remote sql server cannot access my .dll file.

That’s because it is looking for X:\ on the server where the SQL instance is running, not from where the SQL is being run from.

How can I serialize the dll?

You can specify a network path in CREATE ASSEMBLY:

create assembly BarcodeSql 
from '\\yourmachine\sharetox\test.dll' 
WITH PERMISSION_SET = SAFE

Or, you really could serialize it. Using PowerShell:

"0x" + [System.BitConverter]::ToString([System.IO.File]::ReadAllBytes("X:\text.dll")).Replace("-", "")

Which will print out some large hex value. You can then use a VARBINARY literal when creating the assembly:

create assembly BarcodeSql 
from 0x23456789
WITH PERMISSION_SET = SAFE

Where 0x123456789 is the output of the powershell script.
