Working With A Poorly Documented SQL Database.
Feb 6, 2008
One of the primary parts of my job is working with the SQL database of our Enterprise ERP software. One of my primary responsibilities is writing reports based on it's data and since it is not well documented and this is one of my biggest challenges. To top it all off, it's hard to even use their reports to learn the links between tables as the reports run completely in Visual Foxpro.
Is there reasonably priced software that will analyze the database for me and make it easier for me to figure out the relationships between certain tables and such?
TIA,
Dave

Hello all, according to the documentation for the DeviceInfo parameter of the ReportingService.Render method the Xml string fragment of PageHeight and PageWidth for the Image Device Information Settings should and I quote.
The page height, in inches, to set for the report. You must include an integer or decimal value followed by "in" (for example, 11in). This value overrides the report's original settings.
Emphasis mine. Page width is similar. However when I change that value to what is desired for the IMAGE format it has no effect whatsoever no matter what value I place in there.
Indeed the size that is rendered is more related to the current display resolution setting rather than the PageHeight/PageWidth values passed in. In otherwords if my laptop has a higher resolution of 1920x1200 and the server that I deploy this WS to has a lower resolution of 1280x1024, the image rendered on the higher resolution display fits on to an 8.5x11.0 in page with room to spare but on the lower resolution display it is clipped because it does not fit the page.
Is there something that I am doing wrong or is this indeed a bug?
Thank you,
John

I have a Access database which has a address field with multiple data sets in it. I am new to writing code and am having trouble finding a example which will help me split these values out into three seperate fields.
Notice how there is no good order in how they are placed.... Some entry's have commas and some don't. Some have periods and some don't.
EX:
[BILL_ADDR3]
AMHERST, WI. 54406
ASHLAND, WI 54806
ASKOV MN 55704
I then need to convert the state to a state code ie:
2 AK
3 AL
4 AR
5 CA
6 CO
7 CT
8 DC
9 DE
10 FL
11 GA
12 HI
13 IA
14 ID
15 IL
16 IN
17 KS
18 KY
Any good sources of information would be greatly appreciated..... Thank You

Good evening all,
I am new to Microsoft SQL and have been dumped right into the deep end with an anchor around my ankles.
The problem I am experiencing is about 6 months back a guy setup a Microsoft SQL server at my client. He then took his bags and left. Then a developer developed an application which uses a database on this sql server. Everything worked well for around 4 months.
Yesterday IBM Director notified me that I am running dangerously low on disk space on the server. By the time I came in to work this morning I had 12mb free disk space. The evil thing here is the transaction log for the downtime database. It has grown to over 60gb, all because the correct measures were not implemented to prevent this.
The problem that is occuring is no one can do anything on the database now due to the lack of free space. I have tried reading the sql books online but due to my lack of sql experience and knowledge I am stuck.
Can someone please help me? What I would like to do is pull my transaction log down to an acceptable size.
I was thinking of creating a new database and then importing all the data from the current database and then just deleting the current database however am slightly concerned that this may result in some data being lost.
Thanks in advance,
Richard

I'm running the same query on two computers but getting a different query plan. On one of the servers, the query returns in 10 seconds, on the other server it takes over a minute. What the heck!
1. same hardware configuration on both computers
2. same user databases on both computers
3. same NT setup on both computers
4. same software installed on both computers
I can only imagine that MSSQL7 was setup differently and the query optimizer is making a stupid choice. I've compared numerous SQL server options and they are both the same.
1. sp_configure (same on both computers)
2. properties sheet on each server from enterprise manager (same on both computers)
any ideas???

I'm working with a database that is poorly normalized and am doing my best to increase the speed of our queries (changing the database itself is not an option right now). Any help with the following situation would be very much appreciated.
There are two tables involved, described below.
DataTable:
Code Snippet
CodeA char(4),
CodeB char(4),
CodeC char(2),
ColA float,
ColB float,
ColC float,
...
ColZ float
NameTable:
Code Snippet
Abbr char(2),
FullName varchar(50)
In the DataTable, the columns named ColA, ColB, ColC, etc., are described in the NameTable where Abbr would be A, B, C, etc., and FullName would be a "nice" text version describing what's stored in that column. For instance, a record in the NameTable might include Abbr = 'A' and FullName = 'Computer Science', and that means that ColA in the DataTable refers to 'ComputerScience'.
The table I'm trying to optimize the creation of in our ASP.NET application needs to have column headings that could be retrieved like this:
SELECT DISTINCT CodeB, CodeC FROM DataTable WHERE CodeA = @CodeA
(Note that CodeC is really just a different representation of CodeB--think 4-digit year vs. 2-digit year--for any given CodeA.)
The row headings for the table could be retrieved like this:
SELECT FullName FROM NameTable
The cells of the table at any given intersection of a row heading and a column heading can be retrieved like this:
SELECT Col? FROM DataTable WHERE CodeA = @CodeA AND CodeB = @CodeB (this selects a single value)
Where the ? of Col? is determined by the Abbr version of FullName shown in the row heading, and @CodeB is determined by CodeB from the column heading.
Right now this table is generated using a lot of loops in the code of the page that require it to query the database for nearly every cell in the table. Even with this poor database design, there has to be a better way than that. I'm hoping there is a way to create a stored procedure that uses temporary tables and joins, or views, or something like that to create the table on the SQL Server and just send the data to the ASP.NET page in a form that can be directly databound to a GridView.
Thanks in advance for any help!

The following test seems to contradict documented behavior....
1) Running SQL Server 2005 Express with Shared Memory (SM) and TCP enabled connect via ADO.
2) Connect with "localhost", it connects using SM.
3) Disable SM and restart the Server Service.
4) Connect with "localhost", it connects using TCP.
5) Enable SM and restart the Server Service.
6) Connect with "localhost", it still connects using TCP!!
To restore a SM connection, the only way that I have figure out is...
7) Disable TCP and restart the Server Service.
8) Connect with "localhost", it connects using SM.
And then restoring TCP does not change the connection
9) Enable TCP and restart the Server Service.
10) Connect with "localhost", it still connects using SM.
If you run steps 1 - 6 but skip #4, step #6 will connect with SM. So one concludes that the TCP connection is somehow "sticky".
Any ideas on how to force a shared memory connection in step #6?

Hi There
I would like to write sql to check that space used by any given data file in SS2000.
sp_spaceused only returns the total space used by the DB or object in the DB, not for a specific data file.
DBCC SHOWFILESTATS does give me this information , but it is not documented in BOL, i would prefer not to use an undocumented command to ensure future use in later versions. Is DBCC SHOWFILESTATS an undocumented T-SQL command ? If so what documented t-sql command will provide me with this information ?
I could query system table's and work this out , but as mentioned this may not not work in future versions of SS.
Thanx

I have been working on an application which require as much percision as we can get. We have defined all numeric values as (38,16) however when ever we divide a number by the result of a built in function it truncate the percision to 5 decimal place this cause us to have a small but enoying loss in the numbers being caculated we need a minimuim of 8 decimal places or better is there a work around or solution for this problem in sql server 2005. The more percision the better.
example: select tna/(select sum(tna) from taum) from taum where fund_id = 2345
the result is always 5 decimal places even though fund_id tna = 2569698.23 and sum(tna) =98745612325879.36 which should equal .00000002602341683313994 instead the result = .00000

I set up a new mirror server. Everything is good except that the Database Mirroring Monitor is not working for one of the databases. In the monitor the principal data is showing up as blank
If I look at dbm_monitor_data on the principal most of the data columns (e.g. Send_queue_size) are null where as they have data for the other databases.
Both servers are SQL Server 9.0.2047 Enterprise Edition.
Any idea what might be going on here?
Thanks in advance.

Hi
I have set up database mail.
I know the settings are correct because I use the same ones for MS Outlook on the same machine.
I am getting the following error.
-----------------------------------
The mail could not be sent to the recipients because of the mail server failure. (Sending Mail using Account 6 (2007-06-26T06:25:01). Exception Message: Could not connect to mail server. (No such host is known). )
------------------------------------
Service broker is enabled.
Database mail is started.
i really don't know what else it could be.
...Does SQL Server Agent have anything to do with Database mail?
Any other suggestions gratefully accepted..

I have contracted a webproject to be done. My client allready has a website. I need to create another website that replace the existing one with the new look.
This is the problem. The old website has a Database that is associated with user registration & all other data of the company. So, I need to implement the same database to the new website which I am going to develop.
In this case, how can I start? can I add a SQL express databse to the new project and import the data while the development phase? or should I use a SQL server installed while developing the site?
Please give me an easy to understanable reply that I can deal with the old database?

The database server is on computer P4.
Computer P3 has a shared folder with full access.
Computer P5 on which I have my Backup Device and will execute the Backup Database Command using Query Analyzer.
On P5 I created the Backup Device:
USE master
EXEC sp_addumpdevice 'disk', 'myDevice',
'\P3 emp est.bak'
Then I executed the following on P5 Query Analyzer:
Backup Database myDatabase TO myDevice
But I get this error:
Server: Msg 3201, Level 16, State 1, Line 1
Cannot open backup device 'myDevice'. Device error or device off-line. See the SQL Server error log for more details.
Server: Msg 3013, Level 16, State 1, Line 1
BACKUP DATABASE is terminating abnormally.
Any idea? Thanks and regards.

Hi,
I had a Database maintenance plan setup to do complete backup of my SQL Server 2000 database. Same thing was done for the transaction logs as well. And they had resulted in successful backups sometime ago.
But I have noticed that Backups are no longer happening. I cannot find the backup files where they are supposed to land. Some how, I cannot find any error messages relating why the backups are not getting created.
I do not know where I can look up the logs/reports of what possibly is going wrong. I have looked at the usual places and they are not there, for the times I have deliberately tried to submit the jobs.
Any help will be appreciated.
Thanks

I am working on an application that was initially set to connect to a SQL database.
The application is for a Pocket PC and now I have converted the original SQL database to a SQL Mobile database.
Does anyone know if there is a way to change the the code to be able to access the SQL mobile database without having to go through all the code and manually make the changes?
Thanks

Hi, I'm fairly new to the asp.net enviroment.. I have a project in asp.net and I need to upgraded to asp.net 2.0... I just did that, and the few errors that I got are resolved already, the only error that I have not been able to figure out is when I tried to retrieve data from a database I get the following error:
An error has ocurred while establishsing a connection to the server. When connecting to SQL Server 2005, this failure may be caused by the fact that under the default settings SQL Server does not allow remote connections.(provider:Named Pipes Provider, error:40- could not open a connection to SQL Server) and it points to the following line:
Dim ds As DataSet = Microsoft.ApplicationBlocks.Data.SqlHelper.ExecuteDataset(ConfigurationManager.AppSettings(GlobalD.CfgKeyConnString), CommandType.StoredProcedure, "PG_LST_MENU_BY_SUBJECT")
As I said before my project with the previous version works fine, and this is the only part that is giving me trouble...
thank you

Hi all,
I have a site which used a SQL Express database. On my development machine, it works perfectly. As soon as I move it to the production machine, it doesn't work at all. I am pretty confused by what is going on and I really don't want to install Visual Studio on my production machine just to debug it. I am hoping someone might have an idea what could be happening.
Oh, and I have tried setting Everyone to Full Control on the App_Data directory just to test. Still breaks. Below is my web.config connection string:
<connectionStrings> <add name="database_sqlexpress" connectionString="Data Source=.SQLEXPRESS; AttachDbFilename=|DataDirectory|MyDatabase.mdf; integrated security=true; user instance=true"/></connectionStrings>

I installed ASPNETDB with the standard script, but then learned it was possible to integrate this membership db into my existing db (haven't done this yet, but will tomorrow then I'll delete the auto-created ASPNETDB for clarity).That's Great. Now.....I'm not sure the best way to tie this information into with my existing data. I assume I should use the UserID field but how should I do it? Should I update my existing customers table with a copy of the UserID value upon creation? If so, how do I do that? I can create the relations between whichever tables, but I am curious as to your recommended method.Thanks for your help.jb

Hi -
I am having an issue trying to get a linked server to work from SQL Server 2000 SP4 to an Oracle 10.1 database. This server runs Windows 2003 Server.
I had first installed the Oracle client 10.2 on the server and was able to access the Oracle db using the client.
However - when I set up the linked server on SQL Server - and click the "Tables" underneath the linked server - I get the following error.
OLE DB Provider reported an error.
OLE DB error trace [OLE/DB Provider 'MSDAORA' IDBInitialize::Initialize returned]
I uninstalled the 10.2 client and put the Oracle 9i client on the server (on a suggestion from a SQL Server DBA to put an earlier client on the server) - still able to connect using the Oracle client - but not via SQL Server.
I have checked to make sure the MSDAORA.dll is registered. I have also checked that the account that SQL Server starts under has proper permissions to the Oracle folders (that login has admin permissions on the server).
I have named the Linked Server the same name as the service name in tsanames.ora.
I'm at a loss - any ideas? Help - i'm tearing my hair out here.

I am not sure why this is not working it clearly states in the MSDN that it should "
'role'
Is the name of the SQL Server role being checked. role is sysname and can include the database fixed roles or user-defined roles but not server roles.
"
I have seen many questions revolving around this issue on this site and on the net about this but know one can answer it
I have created a new user defined database role called testrole with any owner
then created a new sql login and user (Sql Authentication)
add the user to the database role testrole
check IS_MEMBER and it returns 0
try this with a fixed database role and I get the desired result of 1
this is simple and should not be such a problem for every one
unless I am doing something wrong
Please help

We are having a problem with cross database ownership chaining. Below is a description of the problem:
I have a domain group named DOM1GROUP1
I have a domain user DOM2USER1 who is a member of DOM1GROUP1 (note that they are in different domains)
I have a database DB1 which contains a stored procedure (st_insertdata) that does an insert in a table (tb_data) on DB2
DOM1GROUP1 has been granted login rights on the SQL Server
DOM1GROUP1 is a user in both DB1 and DB2
DOM1GROUP1 has execute rights on procedure st_insertdata and insert rights on table tb_data.
All objects are owned by the dbo schema.
The database owner for DB1 and DB2 is sa
When DOM1USER1 executes st_insertdata an error is returned:
The server principal "DOM1USER1" is not able to access the database "DB2" under the current security context.
I've played around with the options "trustworthy" and "db chaining" but these do not make any difference. The only thing that fixes this problem is if I create a login for DOM2USER1 and grant it access to DB2 (with no other rights other than membership of the public role).
It seems that SQL Server does not recognize that DOM2USER1 is a user in DB2 by virtue of its membership of the domain group DOM1GROUP1. Is there a way to get this to work without granting explicit rights to DOM2USER1?

I installed SQL Server 2005 Enterprise, then SP1 and then SP2, Maintenance Plan worked. But if I installed SQL Server 2005 Enterprise and then SP2 directly (skipping SP1), the Check Database Integrity in Maintenance Plan was not working. The error message is as follows:

Other tasks like Rebuild Index seem to be fine. SP2 is supposed to be inclusive. Does anyone have any ideas on why this is happening.
