Simple Question (connect To Database)

May 13, 2008

How can I connect to another sqlserver instances using a SQL Query Analyzer command? I mean, something like this:



connect (server1.instance1, user, pass) ??
SELECT * FROM MYTABLE;
connect (server1.instance2, user, pass) ??
SELECT * FROM MYTABLE;
connect (server1.instance3, user, pass) ??
SELECT * FROM MYTABLE;

PD: I know I can click in File-->Connect-->etc..., but I want to do this with a T-SQL command

Need Simple Connect/SQL Select In Aspx.vb

May 17, 2006

I have searched for what I think is a simple solution.
In my aspx.vb code page, I need to make a connection to SQL Server (my connection strings are in the web.config file) and then make a simple SQL Select to return one or 2 values.
For example, the user will select a customer on the ASP form, then I need to read a couple of default values from that user's record and display them back onto the form.
Can someone provide the sample code or direct me to this?  I'm thinking that this is rather simple, but I can't seem to make it work.  If I see a sample of exactly what I need to do, such as reading a value using the Northwind sample DB, then I can modify it to fit my table structure, etc.
Thank you.

Simple Database Copy?

Aug 26, 2007

I've looked over the "how do I" stuff but not found a simple, straightforward to simply make a complete snapshot of a relatively small development database (perhaps 2 to 3 meg at this point) so that I can bring it to my local system (from a hosting provider) or vice-versa.
 I see the info on "SQL Server Import and Export Wizard" but I don't find the functionality in SQL Server Management Studio Express -- or am I missing it?
Such a process seems obvious. It's not "replication" is it? I don't need it on an on-going basis -- just an occasional one-time thing.
Mahalos (thanks) in advance for any guidance ... :)  KevInKauai

Simple Database - What Is Best Option?

Jan 31, 2006

Hi,

I am writing a simple program which runs on users xp machines and accesses a simple table on an NT Server.

In otherwords, the database consists of just a single table with perhaps 4 fields and a maximum of 200 records, with low transaction activity (users periodically update their status or check on other users' statuses).

Do I need to use SQL????

What is my best option for such a simple table / database.

Your help would be appreciated.

Simple Database Backup?

May 23, 2007


I thought I would start learning how to backup my SQL Server 2005 database using the simple recovery method. Using the SQL Server Management Studio I started the backup task. In the Back Up Database dialog box the Recovery Model is set to Full and disabled (grayed out). It does not give me the option to switch to the Simple Recovery Model. Is there a setting I need to adjust that will allow me to switch to the Simple Recover Model?

Delay Between CREATE DATABASE And Ability To Connect To That Database

Oct 9, 2006

I have an application that creates a new database during installation,and I've noticed some strange behavior. Once I've created thedatabase, I am able to immediately create tables and populate lookupdata, provided I remain connected to the server. If, however, Idisconnect and attempt to reconnect immediately, I'll get an errorsaying that my login is invalid for the new database.I can get around this by having my code simply wait 5 seconds beforeattempting to reconnect, but I'm curious to see if anybody here cangive an explaination for why this is happening. Here is a bit ofpseudo code to explain what I'm seeing:open new connectioncreate databasecreate tablespopulate tablesclose connection// open new connection /* can't do this yet, as it would break */for (int a=0; a<5; a++){Thread.Sleep(2000)try{open new connectionbreak;}catch{Debug("still waiting...");}}Running my version of this code, I'll see that "still waiting..."message go past 2-3 times before SQL Server wakes up and realizes thatI'm allowed to connect to it. Anybody know why?Thanks,Jason KesterExpat Software Consulting Serviceshttp://www.expatsoftware.com/---Get your own Travel Blog, with itinerary maps and photos!http://www.blogabond.com/

How To Create This Simple Database Search? Thank You.

Dec 7, 2004

Hello,

I have a search form in an ASP.NET/VB page. The form has the input text box and the button "search". The keywords are passed in the URL to results.aspx.

Here is an example of what I get in the URL, when I write the keywords "asp", "book" and "london" in the input text box and click "search":
results.aspx?search=asp%20book%20london

The database table has 3 fields: "id", "title" and "description".

I want to display all the records where at least one of the keywords is found in any of the 2 fields "title" and "description".

1. I suppose I need to get the words out of the URL to be used by SQL.
Maybe: string[] searchString = request.queryString("search").split('search'); ???
How can i make this run when page loads? I supose i need it. Right?

2. How should the SQL look? I supose i need to use the "Like" command
SELECT * FROM books WHERE title LIKE ...
But how to I use it if I can have 1, 2, 3, ... keywords?

Can someone help me?

Thanks,
Miguel

Database Corruption From Simple Query

Aug 8, 2007

Hi- I have questions about mobile database limits. The application is entirely C# / Compact Framework 2.0, using VS2005. Devices we support are all running WM5. We're trying to incorporate what seems to be a large database that the application needs to talk to offline from any network, so it needs to be stored & hosted within the database and hence we started working with the various generations of what is now SQL Server Compact Edition.

In order to profile the responsiveness I worked up a test database with the general collection of fields we are interested in. The main table has 80,000 rows with one primary key and one of the numeric fields indexed. There is a 'nickname' table which contains about 150,000 items with just a string for a nickname and the key that nickname goes with. With all the rows and an alpha index for the nickname field the database is about 42 mb. Which is pushing the amount of storage on the handheld, but of our two models one is fine and one still has about 30 mb free with the DB on the handheld.

My problem seems to be that one kind of device can work with this database and one cannot. The device I was using the prototype the application is a HP iPAC hx2490b. On that device more than once I have corrupted the database, but not yet as a reproducible process.

My other device is a Dell Axim X51. On that device I seem to corrupt the database with very simple actions. Just now I tried a query like (From the Query Analyzer 3.0)





Code Snippet

Select * from ReagentNicknamesTable where alt_names like 'alpha%'

Which should hit 2099 of the 150,000 records. I got about 400 back and then the table was corrupted. On this device I cannot recover the database as there isn't enough disk space for two copies of the DB. So corruption in the field would be a showstopper. But getting corruption from a simple query like this means I really can't use SSCE.

This problem with the dell showed up when I was using the original device sql that came with VS2005. (SQL Server Mobile?) The cabs & dll's were dated from 2005 and had a build number of 3.0.5206.0. I have since updated to the current version of SQL Server Compact Edition and the dlls have build number 3.0.5300.0. The IDE is set to Compact Framwork 2.0, sp1: cgacutil reports CF 2.0.6129.0.

So help! Have I hit some listed or unlisted limits to SSCE on the Compact Framework? thanks.

Cannot Get A Simple Database Application To Work

Apr 24, 2008

Hi,

I tried to create a simple application based on the Sql Server CE samples and, as is typical when I play with databases, the program failed. In this case it failed to even load. The program has a form and a data source that I dropped onto the form. When I run the program the program breaks at this line:




Code Snippetthis._connection = new global::System.Data.SqlServerCe.SqlCeConnection();





The error is:

An unhandled exception of type 'System.DllNotFoundException' occurred in System.Data.SqlServerCe.dll
Additional information: Unable to load DLL 'sqlceme35.dll': The specified module could not be found. (Exception from HRESULT: 0x8007007E)

My first attempt at 'fixing' this was simply to copy the requisite DLLs to my bindebug folder. I found the DLLs here:
C:Program Files (x86)Microsoft SQL Server Compact Editionv3.5 and copied these - sqlcecompact35.dll, sqlceca35.dll, sqlceme35.dll, sqlceoledb35.dll, sqlceqp35.dll and sqlcese35.dll, sqlceer35EN.dll - to my bindebug folder.

Now instead of the first error, I get this error:

An unhandled exception of type 'System.BadImageFormatException' occurred in System.Data.SqlServerCe.dll
Additional information: An attempt was made to load a program with an incorrect format. (Exception from HRESULT: 0x8007000B)


I am running Vista Business (x64) and using (the desktop version of) Sql Server Compact Edition 3.5 with Visual Studio 2008 Standard Edition. The test 'program' is written in C#. (Incidentally I can play with the database with no problems in Visual Studio 2008's server explorer. I can look at data, add data, etc.)

Can anyone please help?

Thanks.

Simple Question About Database Mirroring...

Oct 30, 2007

Hi all,

I am a sysadmin (not a DBA by any means!), so just keep that in mind when answering

I was thinking to set up a database mirror with a manual failover for my Business Objects server. The question I have here, is the database name.. how is it kept?

I have three servers right now, all pointing to the same database. Let's call it DatabaseA. If I set up database mirroring (the links I've seen make it seem simple enough), and I fail over, what happens to the servers that have an ODBC entry to DatabaseA? Do I have to repoint them? Or is the identity of the server transferred over as well?

A little information on this would be greatly appreciated. Right now, we are using doubletake to copy over the database dumps on a constant basis, and I thought that database mirroring would be a better solution to my problem. Please let me know! I am quite new to database mirroring, so take it easy with me

Simple Database Design Question

Jan 18, 2008

I'm designing a database with 3 tables called Function, Test and Scene.

A Function has multiple Tests, but a Test has only one Function. A many to many relationship exists between Test and Scene therefore I need a junction table between these two tables - giving 4 tables in total. The Test table would store a foreign key, the primary key of the Function table.

There is a problem with design though and that is that Functions and Scenes are actually defined before the Test is defined. Therefore it should be possible to create a Function and add to id its Scenes, before Tests have been defined. In other words, Scenes are as much a part of a Function as they are of Tests. Tests are in fact only of relavence to testers. Anyway, to satisfy this scenario, a Junction box is also needed beween Function and Scene. This creates a loop between all tables.

Is this a good approach? Any other suggestions or advice on the matter? Any advice regarding data integrity?

Thanks,

Barry

Problem With Simple Sqlclient Database Acces

Mar 10, 2008

This is a part of my project and that are my first steps. I just want to know if there is a user with "username" already in the database. The MSDN Documentation says that the ExecuteNonQuery() Method returns the number of affected rows. But if I run this code I always get x=-1. What does that mean ?

using (SqlConnection sqlcon = new SqlConnection(System.Configuration.ConfigurationManager.ConnectionStrings["web_db_1"].ConnectionString))        {            SqlCommand cmd = new SqlCommand("Select user_id From users Where username = '" + username + "'", sqlcon);            cmd.CommandType = CommandType.Text;            cmd.Connection.Open();            int x = cmd.ExecuteNonQuery();            cmd.Connection.Close();        }
 Thanks,

Simple Update Kills TEMPDB Database In SQL2005 64-bit

Oct 6, 2006

Following update runs 20 hours till TEMPDB grows up to 400GB and runs out of space with error message:

Could not allocate space for object 'dbo.Large Object Storage System object: 440701391536128' in database 'tempdb' because the 'PRIMARY' filegroup is full. Create disk space by deleting unneeded files, dropping objects in the filegroup, adding additional files to the filegroup, or setting autogrowth on for existing files in the filegroup.

T_PERF_LOC has 30,000,000 rows and T_MASTER_LOC has 2,000,000 rows
There is and index on V_KEY in both tables. CHANNEL_KEY is of Integer datatype and not indexed.

Simple Recovery Model Database - Huge Log File

Nov 3, 2015

Have a database that's in "Simple" recovery mode whose .ldf has grown to 270GB.   This database is a data warehouse so "full" is not required.  I put it in simple mode a month ago and shrunk the log down and now it's filled up the disk. 

What steps can I take to mitigate this in future?  I've read that this is caused by long running transactions which fill the log for DR purposes.  Should I put the database back into full mode and backup/truncate daily.  

The auto-growth is set to 128MB which is very low.

Fatal Error Doing Simple Queries From An Sql 2000 To Sql 2005 Exported Database

Jun 8, 2006

I have been trying to export an sql2000 database to sql2005 with no luck. I continuosly get the error

A severe error occurred on the current command. The results, if any, should be discarded.

SQL Server 2008 :: Changed Database From Full To Simple - Maintenance Plan Failing

Mar 6, 2015

One of my programmers changed their database from full to Simple recovery. Saw that my job that backs up the Full Recovery mode databases failed, so I moved that database to my Simple database backup job plan and removed it from the Full Recovery job. I am unable to remove the db from the Transaction Log task on the Full Plan because when I try to edit that job "Databases with Simple Recovery will be excluded"

My transaction log backups are still failing with the following error: "The statement BACKUP LOG is not allowed while the recovery model is SIMPLE. Use BACKUP DATABASE or change the recovery model using ALTER DATABASE. BACKUP LOG is terminating abnormally.". Possible failure reasons: Problems with the query, "ResultSet" property not set correctly, parameters not set correctly, or connection not established correctly.Just want to remove that database so my Full Recovery backup job does not try to back it up.

SQL Server Admin 2014 :: Unable To Shrink Log On Simple Recovery Mode Database

Jul 27, 2015

I have a database that I am trying to recover space from, it consists mostly of unallocated space, but I can’t seem to get that unused space released.

Database size: 40,245.13 MB
DatafileMB: 38,063.63, DataAvailableMB: 37,085.15
LogfileMB: 2181.51

Sysfiles shows:
fileidgroupidsizemaxsizegrowthstatusperfname
114872144-112820SomeDB
202792332684354561010486420SomeDB_log

The DB is in simple recovery mode. There are no open transactions (used dbcc opentran).

The server is running SQL Server 2014 and the DB is in compatibility mode SQL Server 2008 (100). It was upgraded to 2014 a month or two ago.

I have tried to re-size the log to 100mb, but any way I have tried (none gave errors), the log file remains the same size. I have tied to shrink the log file (through the UI and via DBCC commands) without success; no errors, but also no change in file size.

I have checked Log Reuse Waits, just in case, and as expected it showed “NOTHING” (select log_reuse_wait_desc, name from sys.databases)

I tried running a checkpoint, but that did not allow any resize or shrink to work.

I have tied creating large transactions to move the used point in the log file, in case this was the issue. I did this by creating tables that I drop after large inserts. While it shows me that the log space % used increased, the log file still does not allow the space to be reduced.

The following is what I was using for the transactions to get the log used.

BEGIN TRAN
select a.* into testtable from sysobjects a, sysobjects b, sysobjects c
ROLLBACK TRAN

Each insert creates 93,576,664 rows.

Running dbcc SQLPerf(logspace) :
DBLogSize(MB)LogSpaceUsed(%)Status
SomeDB2181.534.204890

Running dbcc loginfo:
RecoveryUnitIdFileIdFileSizeStartOffsetFSeqNoStatusParityCreateLSN
0211437342728192602640
02114373427211437424645701280

Do I just need to continue running large transactions until the log space used gets high enough to get the “end point” in the log to really move? Is there an easier way to accomplish this (I have several DBs that have the almost identical problem), what I am using moves the Log Space Percent Used about a percent on each execution.

Can Not Connect To Database

Aug 10, 2006

I am new to windows apps in .net 2.0. I am trying to create a windows service that will connect to a database and email info out to people that have had status changes.
Right now, I can not connect to the database. Here is the connection string:
Private cnn As New SqlClient.SqlConnection("Data Source=IPAddress;Initial Catalog=TheServer;Persist Security Info=True;User ID=userid;Password=password provider=SQLOLEDB.1;connect timeout=3600")
This is how I am trying to connect:
cnn.Open()
myCMD.CommandTimeout = 0
dr = myCMD.ExecuteReader
 
I keep getting an error message that I can not be logged on. I know that the credentials are correct because I use them for the web app. Something has to be wrong with my connection string, but what?

Cannot Connect To Sql Database

Sep 1, 2006

 I'm using Visual Web Developer and SQL 2005...It Guives me this error...: An error has occurred while establishing 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: SQL Network Interfaces, error: 26 - Error Locating Server/Instance Specified) I'm tired of guetin and search solution for this errorI've tried everything that i searched over the "net"...made all the configurations possible in sql server 2005 and nothing...Is this right? Or do i need to put some more code in this line or in server is it "localhost:****...: ...connection = New SqlConnection("Server=servernameWebSite1uid=sa;pwd=1234;database=cdcollection")connection.Open()...... Don't know why in sql server i have two object explorer connections when i start the sql server...one is  "servername"...two is "servernamesqlexpress" (but when trying to connect with "servernamesqlexpress" it won't let me, only with "servername")...i use the windows authentication......when i had the VB.NET 2003 and SQL Server 2000, it was much easy to do this... In ASP.NET config i still have the C:inetpubwwwroot path but the files don't go there...now they go to my documentsVisual studio 2005 by default of Visual Web Developer prog. Do i need to change the location? Please help...i'm really desperate...with this...
