I Think I May Be In Hell?!
Jul 6, 2007
So here's the deal. I just started with a new company as a SQL Developer/Analyst. I've got a couple years of experience with SQL Server, mostly 2000, on some fairly large and complex databases (or so I thought).
So I get to this new company and the database structure is just wacky. I've never seen anything like this before. After a few google searches I find a bunch of articles on EAV. Yup, that's what I've gotten myself into. On top of that, it seems to be some exploded EAV hybrid, possibly EAV/CR or something I saw. I've dubbed it the ESEASAADSADAVSAVCRS Schema (Entity Subentity Attribute subattribute attributedata subattributedata attributevalue subattributevalue circular reference system). Gotta laugh so you don't cry, right?
As far as I can tell, all of the data they have is submitted from clients, cleaned, aggregated and then used to generate reports which clients in turn subscribe to. From what I've read and seen here, EAV is horrible for reporting (among other things) and they are having performance problems. The guy 2 times before me made a reporting table structure that does all of the aggregations and spits the data into new tables for the reports to run off of. The problem? The reporting table structure is also EAV!
As the original designer left the company, he said the word CUBE. Then comes in the next "SQL Guru" (she was only here for 6 months, can't imagine why). So they start doing upgrades to SQL 2005 and she takes her predecessors advice and starts designing a dimensional model in SSAS based of the reporting database structure. EAV + CUBES = WTF? Did I happen to mention she didn't have any OLAP experience when she started? (neither do I, at least not in a production environment)
So now there's me sitting here 2 weeks in with an EAV database, a pseudo-EAV reporting database, some unfinished cubes, not wanting to touch anything for fear of the whole thing imploding.
Here are some of the factors I must take into account:
1. The company website serves as the client UI and is tightly integrated with the EAV schema.
2. New data sources come and go quite often which means lots of attribute changes to the data
3. After looking at the data with what little SSAS knowledge I have, it seems that going this direction might just be useless. I believe all of the fact/measure data is stored in all of these dynamic attributes and it seems like I would be changing them on every load.
4. I thought about dropping the cube idea and redesigning the reporting database structure to 3NF and then pumping the data from EAV to 3NF for reporting but... uhhh... damn, my mind went blank
4. My brain is fried from looking at this thing so I can't remember what other points I was going to bring up... please give some advice.

hi all,
ive been having this problem recently and havnt been able to hunt down a solution for it....
i have a table. 3 columns. name(varchar),age(int) and job(varchar)
i have a stored procedure which takes in name age and job from a form and attemps to through them into the db,but its giving me...
Parameter object is improperly defined. Inconsistent or incomplete information was provided.
or
Type Mismatch..
lovely!
Here's some code for the sproc
CREATE proc sp_insertinfo
@name varchar(50),
@age int,
@job varchar(50)
as
insert into users
values (@name,@age,@job)
GO
and for the actual ASP file...
strConn="Provider=SQLOLEDB;User ID=sa; Password=xxxxx; Initial Catalog=Skills; Data Source=xxxxx"
oConn.Open strConn
Set oCmd.ActiveConnection = oConn
'assign form info to params
name=Request.Form("name")
age=Request.Form("age")
job=Request.Form("job")
'call sproc
oCmd.CommandText = "call sp_insertinfo @name,@age,@job"
'Append params
oCmd.Parameters.Append oCmd.CreateParameter("name", adVarChar, adParamInput, 50, name)
oCmd.Parameters.Append oCmd.CreateParameter("age", adInteger, adParamInput,4,age)
oCmd.Parameters.Append oCmd.CreateParameter("job", adVarChar, adParamInput, 50, job)
'execute the sproc with the params
Set oRs = oCmd.Execute
Anyways it would be great if you could check that out there. Any help def appreciated as this "simple" prob is holding me up big style!
Cheers!

hi, im currently on sql hell right now. im having a hard time learning this sql thingie....
...the thing is this: im currently using the book ASP.NET Unleashed and most of the examples there are on SQL. what i was trying to do before was convert everything to OleDb to fit the ms access which i have right now.
unfortunately, some of the codes seem not to work properly. maybe its because of im using OleDb...
so what i did was i downloaded the MSDE sp3 package and installed it on my PC. now that i have an sql server for my WebMatrix, i just dont know what to do next? i mean, where do i put the sql sample databases like northwind and pubs???
im really confused about this sql thing. i really hate it.
help!!!

All,
Is there a way to hardcode the ip address instead of the Server name in replication script? One of our server is registering 2 IP addresses for itself in DNS. One valid and one invalid. Which is causing the replication to fail.
exec sp_addsubscription @publication = N'WorkFlowtoStats_Weekly', @article = N'all', @subscriber = N'IMGSTAT01', @destination_db = N'Stats', @sync_type = N'automatic', @update_mode = N'read only', @offloadagent = 0, @dts_package_location = N'distributor'
GO
Thanks

I have two tables:
table1
field1 = identity
field2 ...
field3 ...
field4 ...
table 2
field1 = identity
field2 = foreign key (table1 field1)
field3 ...
When I delete a row in table1, a cascade delete relationship deletes the appropriate table2 row(s). Since I have a trigger on table2 that updates a few fields in table1 (field3, field4), when I try to delete table1, I get an error. The cascade delete tries to fire off the trigger in table2, which in turn tries to update table1 fields and thus fails. How do I circumvent the triggers from firing?
Triggers look something like this:
CREATE TRIGGER trg_delete_table1_field3_field4
ON dbo.table2
FOR DELETE
AS
BEGIN
DECLARE @newField3Value as money
DECLARE @newField4Value as money
Set @newField3Value = (SELECT SUM(field3) FROM table2 WHERE key = (SELECT key FROM deleted))
Set @newField4Value = (SELECT SUM(field4) FROM table2 WHERE key = (SELECT key FROM deleted))
UPDATE table1
SET field3 = @newField3Value ,
field4 = @newField4Value
WHERE key IN (SELECT key FROM deleted)
END

I have several smallish databases running on an MPC (www.mpccorp.com) server. Device Manager says it has an LSI Logic 1020/1030 Ultra320 SCSI Adapter and a MegaRAID SATA 150-6 RAID controller. It doesn't have any kind of Windows-accessible RAID management interface.
Several months ago I started getting corrupt databases. They would get errors that a DBCC CHECKDB couldn't fix. I never found specific help on this but most of the similar issues I saw pointed toward the RAID controller. We contacted the MPC, who had updated RAID firmware for us to try. We flashed the RAID card reformatted the disks, and restored everything from the last good backup (it had been throwing errors for a couple weeks before I noticed them).
All was good for about a month, but now I'm back to the same situation. I have several corrupt databases. I have good backups, but can't even restore them because I get errors on the restore. My next step is to pay for an incident with Microsoft, but I suspect they'll just point me back to the hardware. If you have any suggestions for problem determination or resolution, I'd sure appreciate them!
Cheers,
Martin Nickel
Sample corruption error:
SQL Server detected a logical consistency-based I/O error: torn page (expected signature: 0x0; actual signature: 0x3f380c2c). It occurred during a read of page (1:9) in database ID 9 at offset 0x00000000012000 in file 'E:Program FilesMicrosoft SQL ServerMSSQLDataMyDB.mdf'. Additional messages in the SQL Server error log or system event log may provide more detail. This is a severe error condition that threatens database integrity and must be corrected immediately. Complete a full database consistency check (DBCC CHECKDB). This error can be caused by many factors; for more information<c/> see SQL Server Books Online.
Sample error during DBCC CHECKDB:
Msg 8939, Level 16, State 98, Line 1
Table error: Object ID 0, index ID -1, partition ID 0, alloc unit ID -9156028125792763904 (type Unknown), page (34262:2139451659). Test (IS_OFF (BUF_IOERR, pBUF->bstat)) failed. Values are 29362185 and -4.
Repairing this error requires other errors to be corrected first.
Sample database restore error:
Msg 3283, Level 16, State 1, Line 1
The file "MyDB_log" failed to initialize correctly. Examine the error logs for more details.
Msg 3013, Level 16, State 1, Line 1
RESTORE DATABASE is terminating abnormally.

Ok, I posted here recently and received helpful replies which allowed me to work around a problem. The original question was posted here:http://forums.asp.net/t/1112669.aspxBut because I'm learning both asp.net 2.0 AND vb 2005 I sort of want to get to the bottom of stuff. I've found out what was going wrong, but I don't understand it.The problem related to retrieving an output parameter to a stored procedure. I was adding the parameter to the command object I was using as follows: cmd.Parameters.Add(New SqlParameter("@memberid", Data.SqlDbType.Int, 0, Data.ParameterDirection.Output)) but it wasn't working (ie I wasn't seeing the return value). A helpful poster's work around was to instead do this: Dim pMemberId As New SqlParameter("@memberid", SqlDbType.Int)pMemberId.Direction = ParameterDirection.Outputcmd.Parameters.Add(pMemberId) Having poked around some more, I've discovered that if I use the original code and then type:?cmd.Parameters("@memberid").Direction I get the value:Input {1}This even happens if I explicitly use 2 instead of Data.ParameterDirection.Output Can anyone explain why this is happening? What's the point of allowing me to pass a parameter into a constructor if it's just going to ignore it?

Hi all,
I'm trying to use DTS to import a space delimited file. One column uses " as a text qualifier so I set this in the options. The problem arises when a " shows up between the 2 text qualifiers. It's seen as a set of qualifiers with a 2nd qualifier with no end. I obviously get an error at this point. Anyone have any good advice on how to squash this one?

Hello all,
Does anybody know where SSIS Data Connections are stored? Whenever one creates a Connection Manager, a list of all created Data Connections appears. It's very quick and easy to create a Connection Manager from an existing Data Connection, so really the latter are in essence the Connection Managers and are thus part of the application. It is therefore important to back them up if for example one wants to migrate the application to another computer. I have looked everywhere in Documents and Settings and Program Files and I can't find any folder or file where these Data Connections are stored! It's annoying to have this mysterious black-box behaviour!
Does anybody know?
Thanks in advance,
Jerome Smith

Ok, I have tried everything I can think of, but I am still getting errors to do with SQL server 2005 beta. Since the beta expired on all the VS.net 2005 I thought it would be a good idea to uninstall the lot to save some hard disk space...how wrong I was!!

I originally developed my application using SQL 2005 Developer Edition, but want to switch to using an XCOPY deployed DB on SQL Express for deployement.
I have successfully copied the database.mdf/ldf files over to me project, and can connect using Data Source=.SQLExpress and AttachDbFilename=|DataDirectory|[database].mdf attributes.
The question is, how do I enable CLR integration for my C# SP's?
I've tried executing the following in various places:
sp_configure 'clr enabled', 1
go
reconfigure
go
But I obviously haven't hit the spot because I'm getting the following error when VS deploys my SP library:
Error: starting database upload transaction failed.
Error: Access is denied. (Exception from HRESULT: 0x80070005 (E_ACCESSDENIED))
Any ideas?

I have a brand-new Toshiba laptop, running Vista Business, that I installed SQL Express onto. Prior to installation, I was sure to install all the requisite IIS components so SSRS would install.
The installation ran fine -- installed all components. The configuration ran fine. Everything that is supposed to be green shows green
But, when I go to http://localhost/ReportServer, I get:
Server Error in Application "Default Web Site/ReportServer"
--------------------------------------------------------------------------------
HTTP Error 404.2 - Not Found
Description: The page you are requesting cannot be served because of the ISAPI and CGI Restriction list settings on the Web server.
Error Code: 0x800704ec
Notification: ExecuteRequestHandler
Module: IsapiModule
Requested URL: http://localhost:80/ReportServer
Physical Path: C:Program FilesMicrosoft SQL ServerMSSQL.2Reporting ServicesReportServer
Logon User: Anonymous
Logon Method: Anonymous
Handler: AboMapperCustom-34881
Most likely causes:
No handler mapping for this request was found. A feature may have to be installed.
The Web service extension for the requested resource is not enabled on the server.
The mapping for the extension points to the incorrect location.
The extension was misspelled in the browser or the Web server.
What you can try:
Install the feature that handles this request. For example, if you get this error for an .ASPX page, you may have to install ASP.NET via IIS setup.
Verify that the Web service extension requested is enabled on the server.
Open the IIS Manager and navigate to the server level.
In the Features view, double-click ISAPI and CGI Restrictions to verify that the Web service extension is set to Allowed.
If the extension is not in the list, click Add in the Actions pane.
In the Add ISAPI and CGI Restrictions dialog box, type the path of the .dll or .exe file in the ISAPI or CGI Path box, or click Browse to navigate to the location of the file.
In the Description box, type a brief description of the restriction.
(Optional) Check "Allow extension path to execute" to allow the restriction to run automatically. If you do not check this option, the restriction status is Not Allowed, which is the default. You can allow the restriction later by selecting it and clicking Allow on the Actions pane.
Click OK.
NOTE: Make sure that this Web service extension or CGI is needed for your Web server before adding it to the list.
Verify that the location of the extension is correct.
Verify that the URL for the extension is spelled correctly both in the browser and the Web server.
Create a tracing rule to track failed requests for this HTTP status code. For more information about creating a tracing rule for failed requests, click here.
More Information... This error occurs when the necessary Web service extension is not enabled, the location or the name of the extension are misspelled or incorrectly entered.
--------------------------------------------------------------------------------
Server Version Information: Internet Information Services 7.0.
The only lead I could find when I googled this error was a reference to running appcmd to ensure that asp.net was enabled. It sure looks like it is:
C:WindowsSystem32inetsrv>appcmd list config -section:isapiCgiRestriction
<system.webServer>
<security>
<isapiCgiRestriction>
<add path="%windir%system32inetsrvasp.dll" allowed="true" groupId="ASP" description="Active Server Pages" />
<add path="%windir%Microsoft.NETFrameworkv2.0.50727aspnet_isapi.dll" allowed="true" groupId="ASP.NET v2.0.50727" description="ASP.NET v2.0.50727" />
</isapiCgiRestriction>
</security>
</system.webServer>
C:WindowsSystem32inetsrv>
Honestly... I'm out of ideas. I've been messing with this for 8 hours now, and I'm ready to fling the laptop out the window. I've completely UNinstalled SQL Server, IIS, reinstalled both, repeated the uninstall/reinstall after double-checking all files were deleted, and so on.
Does *anyone* know how to resolve this error? I checked IIS.NET and although they have a few references to it (not within the Reporting Services context) there never seems to be a definitive answer as to what the solution is.
