Database Schema Exported......
Jul 10, 2002MS SQL 6.5
NT
I have been asked to export the database schema (containing table names, field names, data types, field lengths, field defaults, nulls, etc) to an MS Excel spread sheet. "sp_help filename" provides some data but the format is difficult to manage.
All help with this matter would be greatly appreciated....
Thanks in advance.

Where are CLR Assemblies stored on SQL Server when compiled from a SQL Server Project?
Are they stored in a specific folder or stored inside the database?
Does deleting the Assembly under Programmability/Assemblies remove the Assembly from the server?
Thanks.
Export To A Text File, Then Name The Exported File The Date Is Was Exported, Then Zip
Jul 3, 2007
Hi folks
Any help on my request would greatly be appreciated. We are trying to maintain the growth of a particular table, by exporting and deleting data that is older then 90 days. Here are the 4 steps I need to do. I believe I know how to do 1 and 4;
1. Create a job that continously exports data that is older then 90 days to a text file
select *
from table A
WHERE (CREATED < DATEADD(DAY, - 90, GETDATE()))
(the column 'created' datatype is datetime and looks like this '3/5/2007 3:11:44 PM')
2. Have the job automatically name the exported file, the day it was exported (i.e. 07032007 (todays date))
3. Then zip that file (we're using 7-zip)
4. Then delete the data out of the table
delete
from table A
WHERE (CREATED < DATEADD(DAY, - 90, GETDATE()))
Im not a big scripter/coder, so I was wondering if there is anything I could do in SSIS. Im more familiar with DTS, so any kind of baby steps you could provide in SSIS, would go a long way.
Thank you so much.

View 10 Replies View RelatedHow To Import Exported Images From SQL Server
Mar 31, 2008Hello,
Here is my problem:
There is some data which we need to move from a vendor database to our Oracle database. The vendor has provided us with the exported data from their database. The data is in a text file with some delimiters to identify where each column value ends.
One of the table columns extracted has an image. I dont have real image files, but I have the image in the exported format (hex value - something like 'FFD8FFE000104A46494600010001009600960000FFFE001...". Now I need to import this as a image into a LONG RAW or BLOB column in Oracle database. But it is not possible to do so in Oracle, so we have planned a work around for this.
1) Import the data back into SQL Server
2) Export the actual image files(.jpeg or .gif) on the desktop
3) Import the image files from desktop to Oracle database.
The text file that contains table information has rows like below.
2~jones~jenny~j~bad show~1989-05-14 00:00:00.000~304303F.......
(last value should go into an image column)
I would like to know how to import such hex-stored image data into image column in database table. I have tried to direct import using BULK INSERT, but doesn't work.
I would appriciate if someone can provide some working code as well, which shows how to achieve the above functionality.
Thanks.
Cant Sort Data In Exported Excel File From Sql Server Reporting Server
Feb 7, 2008
Hello,
I am new to this sql server reporting server technology. I have a requirement like the table header should repeat in all pages of the exported excel's print preview. So I have created the header columns with fixed lenths as same as table's header in the page header of the report. Then only the Header will repeat in all pages of the print preview.
But the problem is when doing like this, many of the columns have been merged together. The report layout is ok. But cant sort the data. It says a message "This operation requires the merged cells to be identically sized."
In some forms i have found the header control's edges need to be sized identically with the tables' columns edges. I did it. But still the columns are merged when exporting.
Please help me out from this.
Thanks in advance.

Updating Assemblies
Oct 31, 2007
Hi, a silly question here.
I wrote an assembly and attached to a trigger in one of my tables. It works as I expected, but then I decided to modify the code, say adding some new triggers that I will use with other tables. Then I realize that in order to update my new version of the assembly in SQL first I need to remove the trigger in the table, then remove the assembly, add the new version and finally run a script to create the trigger again in the table.
How could I avoid going through all this process everytime I want to update my assembly?
Thank you!
Dependant Assemblies In CLR
Oct 12, 2006This is related to one of my previous posts.
I am running a CLR stored proc that goes to an EDS (Novell) server with LDAP and returns records into a SQL table.
I am using the Novell ldap library.
I want to do this with SSL so my code referneces the Mono security library as well.
However when I make the call to the stored proc to run in SSL, I get an object not found error. I do not think that the the Novell assembly can "find" the Mono assembly.
Two points:
1/ I can do the SSL if I run it as an asp.net page (so I know the SSL works)
2/ The proc runs and pulls all the records in non-SSL (so I know the proc works)
Any ideas?
Thanks,

Full Qualified Assemblies
Oct 10, 2007
Hi all,
I need to dynamically create a ADO.NET connection manger
so, my question is if it is safe to create it with the string that is generated (ConnectionManagerType) when creating the connection manager manually on my PC.
I understood that this string is the full qualified name of the assembly, so will it be different when I create it on another P.C or it is fixed on all P.Cs ?
Thanks ahead

Using Pre-Built Serialization Assemblies
Apr 12, 2007I have followed the steps outlined in the knowledge base article http://support.microsoft.com/kb/913668 for effecting Xml Serialization within the SQL CLR. That is, I have
1. Prebuilt the serialization assembly X.Serializers for the types in assembly X and,
2. Registered both assemblies with SQL Server via the create assembly directive
Yet, when I attempt to create an XmlSerializer on the basis of one of the types defined in X, SQL CLR ignores the pre-built serialization assembly and attempts to dynamically create/load the assembly. Since dynamic loading is disallowed, this fails with the expected exception:
System.InvalidOperationException: Cannot load dynamically generated serialization assembly. In some hosting environments assembly load functionality is restricted, consider using pre-generated serializer. Please see inner exception for more information. ---> System.IO.FileLoadException: LoadFrom(), LoadFile(), Load(byte[]) and LoadModule() have been disabled by the host.

View 4 Replies View RelatedC++ Assemblies And Security Context
Mar 23, 2008I have two questions.
How can I run my C++ assembly in safe mode?
I'm building a SQL function from C++ and compile my assembly with /clrafe. After that I create the assembly with SAFE permission sets and create the function, both in SQL. But the server don't accept load or execute the function because of permission error. It says:
Code Snippet
"An error occurred in the Microsoft .NET Framework while trying to load assembly id 65561. The server may be running out of resources, or the assembly may not be trusted with PERMISSIONSET = EXTERNALACCESS or UNSAFE. Run the query again, or check documentation to see how to solve the assembly trust issues."
Does the terminology coince with the technology, or is it diffrent "safety" conditions we are speaking about? One for the SQL permission set, and another safety for CLR type-safe assemblies?
Anyway, after playing around a bit, and following the tricks from this thread. I managed to load and execute the function, but only in UNSAFE permission (unrestricted mode?)
---8<----
My second question is can I use unrestricted mode for assembly compiled with /clr (mixed CLR)?
I'm asking, because I have some C source code that I want to reuse, and for this I can't be type-safe and therefore need to compile only with /clr (mixed CLR).
Should I go back to the plain C API in SQL 2000 to implement such function in SQL 2005, and ignore all new things in c++/CLR/.NET?
If you have any points to C++ sample code, then please forward this to me.

Load Multiple Signed Assemblies
Aug 18, 2006I am trying to load multiple strongly named assemblies into the same database which are signed with the same .snk file (signed in Visual Studio). I use the following code to create an asymmetric key and login as Books Online recommends:
CREATE ASYMMETRIC KEY SQLCLRKey FROM FILE = 'D:dbainAssembly.dll'
CREATE LOGIN CLRAssembler FROM ASYMMETRIC KEY SQLCLRKey
GRANT UNSAFE ASSEMBLY TO CLRAssembler
GRANT EXTERNAL ACCESS ASSEMBLY TO CLRAssembler
REVOKE CONNECT SQL FROM CLRAssembler
Do I need to create a new login and asymmetric key for each assembly I load? If so, do I need to sign each with a different key because its giving me an error message when I try to create 2 separate asymmetric keys/logins from 2 different assemblies which have been signed with the same .snk file.
The only way I've gotten everything to load properly is to create a separate key for each assembly and sign each, then create separate logins and asymmetric keys in the database.
Is this the only way to do this? Or am I missing something?

Problem Creating Assembly Using Other Assemblies
Mar 7, 2007Hi,I have developed a Stored procedure to output text to a text file, after doing a lot of reading here.
I want to be able to output data to a Postgres database, to be used for web mapping. I have referenced an Assembly Npgsql.dll so I can send updates to the postgres database when my ms sql database is updated. However, after building my class library, when I try to CREATE ASSEMBLY in sql server 2005 express, it sends out a message:
Msg 10301, Level 16, State 1, Line 1
Assembly 'ClassLibrary1' references assembly 'system.drawing, version=2.0.0.0, culture=neutral, publickeytoken=b03f5f7f11d50a3a.', which is not present in the current database. SQL Server attempted to locate and automatically load the referenced assembly from the same location where referring assembly came from, but that operation has failed (reason: 2(error not found)). Please load the referenced assembly into the current database and retry your request.
The error seems to be in the Npgsql.dll assembly, can anybody please shed some light on this.
I tried to load the system.drawing assembly, and can do so in Unrestricted mode. It then spits out the same problem for System.Windows.Forms.dll.
I am still very new to all of this so any help would be appreciated.

Referencing System/CLR Assemblies In SQLCLR
Jul 23, 2006Throughout the course of this book and even before it I have come across conflicting information regarding how SQLCLR attempts to resolve system/CLR assembly references. For example, prior to my latest read thourgh April BOL 2005, I thought SQLCLR attempted to resolve these references implicity for you via the local machine's GAC. Yet here is what I found while trying to help another person in this forum yesterday in BOL...
Assembly Validation
SQL Server performs checks on the assembly binaries uploaded by the CREATE ASSEMBLY statement to guarantee the following:
The assembly binary is well formed with valid metadata and code segments, and the code segments have valid Microsoft Intermediate language (MSIL) instructions.
The set of system assemblies it references is one of the following supported assemblies in SQL Server: Microsoft.Visualbasic.dll, Mscorlib.dll, System.Data.dll, System.dll, System.Xml.dll, Microsoft.Visualc.dll, Custommarshallers.dll, System.Security.dll, System.Web.Services.dll, and System.Data.SqlXml.dll. Other system assemblies can be referenced, but they must be explicitly registered in the database.
For assemblies created by using SAFE or EXTERNAL ACCESS permission sets:
The assembly code should be type-safe. Type safety is established by running the common language runtime verifier against the assembly.
The assembly should not contain any static data members in its classes unless they are marked as read-only.
The classes in the assembly cannot contain finalizer methods.
The classes or methods of the assembly should be annotated only with allowed code attributes. For more information, see Custom Attributes for CLR Routines.
Besides the previous checks that are performed when CREATE ASSEMBLY executes, there are additional checks that are performed at execution time of the code in the assembly:
Calling certain Microsoft .NET Framework APIs that require a specific Code Access Permission may fail if the permission set of the assembly does not include that permission.
For SAFE and EXTERNAL_ACCESS assemblies, any attempt to call .NET Framework APIs that are annotated with certain HostProtectionAttributes will fail.
COULD SOMEONE PLEASE GIVE ME THE DEFENITE ANSWER ON HOW THIS WORKS!
