由 廉价感情. 提交于 2019-11-27 22:52:48
问题 I'm trying to debug a CLR based StoredProcedure in Visual Studio 2012 RTM. I have a Sql Database Project. When I try to debug my script file using RightClick -> Execute with debugger it pop ups a warning about harmfulness of attaching a process and when I accept it just say that : Unable to debug .Net Code. Could not attach to SQL Server process on 'Devserver'. I've done many different things : I've added my domain user to sysadmin SQL Server Role. I've run MSVSMON.EXE on the Remote Server

SQLCLR using the wrong version of the .NET Framework

由 冷暖自知 提交于 2019-11-27 21:10:05
During a recent restart of our development server the SQL Server started using .NET 4.0 for the SQLCLR. This means that nothing using the CLR in SQL works, or at least that's my understanding by reading these sources: http://software.intel.com/en-us/blogs/2009/10/16/sql-server-2008-sqlclr-net-framework-version/ www.sqlskills.com/BLOGS/BOBB/post/On-SQL-Server-and-NET-40.aspx All we get are error messages of this type: Msg 6517, Level 16, State 1, Line 1 Failed to create AppDomain "xxx.dbo[ddl].3". Method's type signature is not Interop compatible. Running the statement (as suggested by @john

Hashing more than 8000 bytes in SQL Server

由 情到浓时终转凉″ 提交于 2019-11-27 16:55:39
问题 SQL Server's hashing function HASHBYTES has an input limit of 8000 bytes. How do you hash larger strings? 回答1: You could hash 8k (or 4k or 2k) chunks of the input and then either concatenate those hashes or hash them into a new hash value. This might get difficult though if you have to create a similar algorithm (in an external .NET app for example) to compare hashes created outside of SQL Server. Another option: Lean on SQL Server's CLR integration and perform the hashing in a .NET assembly.

Is it possible to use user defined aggregates (clr) with window functions (over)?

Is it possible to use user defined aggregates (clr) with window functions (over) ? Can't find the answer in the documentation: http://technet.microsoft.com/en-us/library/ms190678.aspx You're right that it's tricky to find anything in the documentation. But searching the Connect website, I managed to find this gem : Today, you can use CLR aggregates with OVER clause and PARTITION BY just like regular aggregate functions. Once we have support for window functions... Which was a response from Microsoft. However, searching on the Connect site was what I did whilst I was waiting for my aged machine

Advantage of SQL SERVER CLR

由 纵然是瞬间 提交于 2019-11-27 14:52:37
问题 What advantages does SQLServer CLR offer over T-SQL? Is using .NET syntax easier than T-SQL? I see that you can define user types, but I'm not quite clear on why that's better. For example, you could define an email type and it would have a prefix property and a domain property. You could then search on domain or prefix or both. However, I don't see how that's any different from adding a couple of columns one called prefix and one called domain and searching on them individually. Maybe

Reverse the order of words in TSQL

由 折月煮酒 提交于 2019-11-27 07:16:39
问题 I would like to know how (if it is possible) to reverse the order of words returned from a TSQL string (varchar). I know about the TSQL REVERSE function but the also reverses the letters in the word for example: Input > We want to tell you we all love StackOverflow Output > wolfrevOkcatS evol lla ew uoy llet ot tnaw eW I want to actually achieve the following in TSQL: Input > We want to tell you we all love StackOverflow Output > Stackoverflow love all we you tell to want We The only slightly

CLR SQL Assembly: Get the Bytestream?

由 烈酒焚心 提交于 2019-11-27 02:45:08
问题 I have a SQL CLR dll I want to deploy, but have found you can embed the byte stream/varbinary_literal/ varbinary_expression/assembly bits into a text file to get around the messy hassle of packaging a DLL and making sure it's accessible for the CREATE ASSEMBLY command. But what I have yet to find is how to get that byte stream/varbinary_literal/ varbinary_expression/assembly bits value. I haven't found any consistent terminology, and what I keep finding in using Load() . 回答1: It's just a hex

SQL Server 2008 and HashBytes

由 拜拜、爱过 提交于 2019-11-27 02:15:23
问题 I have quite a large nvarchar which I wish to pass to the HashBytes function. I get the error: "String or binary would be truncated. Cannot insert the value NULL into column 'colname', tbale 'table'; column does not allow nulls. UPDATE fails. The statement has been terminated." Being ever resourceful, I discovered this was due to the HashBytes function having a maximum limit of 8000 bytes. Further searching showed me a 'solution' where my large varchar would be divided and hashed seperately

How to register System.DirectoryServices for use in SQL CLR User Functions?

由 元气小坏坏 提交于 2019-11-27 02:13:38
问题 I am porting an old 3 2-bit COM component that was written in VB6 for the purpose of reading and writing to an Active Directory server. The new solution will be in C# and will use SQL CLR user functions. The assembly that I am trying to deploy to SQL Server contains a reference to System.DirectoryServices . The project does compile without any errors but I am unable to deploy the assembly to the SQL Server because of the following error: Error: Assembly 'system.directoryservices, version=2.0

How to notify a windows service(c#) of a DB Table Change(sql 2005)?

由 倾然丶 夕夏残阳落幕 提交于 2019-11-27 01:02:19
问题 I have a table with a heavy load(many inserts/updates/deletes) in a SQL2005 database. I'd like to do some post processing for all these changes in as close to real time as possible(asynchronously so as not to lock the table in any way). I've looked a number of possible solutions but just can't seem to find that one neat solution that feels right. The kind of post processing is fairly heavy as well, so much so that the windows listener service is actually going to pass the processing over to a
