Hi, I'm planning to develop a project on .NET using Sql server 2005. Just stuck at a point where I need to decide that Should I use 2 or 3 huge databases with a lot of tables and data into it or should i create a lot of databases which would contain small chunks of data. Please let me know which option would give me a better performance. Thanks in advance
God is great. We are not God. But we still can be great.
I have a single .bak file containing full backups of 20+ databases.
Whats the best way of creating and restoring these database onto an instance on a separate server.
note that this is to migrate the whole instance of sql server onto a newly build server.
I'm building an app that will data stored in multiple databases. I have an endpoint with a single webmethod like so:
CREATE ENDPOINT [Rosters_Endpoint]
AUTHORIZATION [ADHEadministrator]
STATE=STARTED
AS HTTP (PATH=N'/SQL/Rosters', PORTS = (CLEAR), AUTHENTICATION = (DIGEST, NTLM, KERBEROS, INTEGRATED), SITE=N'10.0.1.116', CLEAR_PORT = 8080, COMPRESSION=DISABLED)
FOR SOAP (
WEBMETHOD 'GetACSStudents'( NAME=N'[fadb].[dbo].[GetACSStudents]'
, SCHEMA=DEFAULT
, FORMAT=ALL_RESULTS), BATCHES=DISABLED, WSDL=N'[master].[sys].[sp_http_generate_wsdl_defaultcomplexorsimple]', SESSIONS=DISABLED, SESSION_TIMEOUT=60, DATABASE=N'fadb', NAMESPACE=N'http://tempUri.org/', SCHEMA=STANDARD, CHARACTER_SET=XML)
Each webmethod will be accessed thru a multiview on the page.
It would seem to me that I can describe the webmethods using a fully qualified stored proc name and that wouldn't cause a big problem. But, my question is what does that DATABASE=N'fadb' clause do?
Does anybody see a problem with using a single endpoint to access multiple databases?
Any advice would be greatly appreciated as this is my first web app using this data access method.
Thanks.
HI Guys,
I just need to add multiple catalogs to the same linked server, in Sql Server 2000 or Sql Server 2005. Here i need only to add 3 databases in to a single linked server name.
Thanks In Advance,

Hi,
I want to create two databases by restoring from a
single backup file in sql server. I am using 2005-sqlexpress .Is it possible?
Thanx in advance..
I have a backup that contains multiple databases. I am restoring it to a different server. How do I restore each database? Tried to restore under SQL Server Management Studio, but can only restore one of many from the backup (it appears it has only 1 logical file name in the backup) If you can refer me to a web page that would be great. I tried googling the topic but nothing seems to come up.

<quote>However, all these techniques for coordinating client redirection with a database mirroring have an important limitation. Database mirroring occurs only at the database level, not the server level. Be careful if your application relies on querying several databases on a server, or uses multi-part object names to query across several databases. When several databases reside on one server, and they are mirrored to a standby server, it is possible that one of several databases might fail over to the standby but the others remain on the original server. In that case, you might need one connection per database that you are querying, so that you do not attempt cross-database queries on a standby server where only one database is a principal and the remaining are mirrors.</quote>
Also I read somewhere that if one mirrored DB fails, all other mirrored DB should also be transferred to the mirror.
For example: Let's say Srv1 (principle) and Srv2 (mirror) and Srv3(witness) are SQL servers with only default instances. The SQL instance has 4 DBs (DB1, DB2, DB3, DB4) and all of them are mirrored to Srv2.
An ASP.NET application has four seperate connection strings like:
objConn1 --> Data Source=Srv1;Failover Partner=Srv2;Initial Catalog=DB1;Integrated Security=True;
objConn1.connect();
objConn2 --> Data Source=Srv1;Failover Partner=Srv2;Initial Catalog=DB2;Integrated Security=True;
objConn2.connect();
objConn3 --> Data Source=Srv1;Failover Partner=Srv2;Initial Catalog=DB3;Integrated Security=True;
objConn3.connect();
objConn4 --> Data Source=Srv1;Failover Partner=Srv2;Initial Catalog=DB4;Integrated Security=True;
objConn4.connect();
If DB2 failsover to Srv2 (mirror), why should all other DBs be failedover?
Thanks
I have to mirror 3 DBs on my sql server instance . I have restored there full backups and log backups on mirror.I have also created endpoints on principal and mirror using default ports 5022 and 5023.
know if i can use the same endpoint for the databases on principal instance ?
I have multiple databases in the server and all my databases have tables: stdVersions, stdChangeLog. The stdVersions table have field called DatabaseVersion which stored the version of the database. The stdChangeLog table have a field called ChangedOn which stored the date of any change made in the database.
I need to write a query/stored procedure/function that will return all the database names, version and the date changed on. The results should look something like this:
DatabaseName DatabaseVersion DateChangedOn
OK5_AAGLASS 5.10.1.2 2015/01/12
OK5_SHOPRITE 5.9.1.6 2015/01/10
OK5_SALDANHA 5.10.1.2 2014/12/23
The results should be ordered by DateChangedOn.
I want to store a small cirle in a text field. Can anyone tell me how I can enter it in ascii code.
Thanks
Dear Readers,Is it possible, like in Access, to link to tables in other SQL databases that are on the same server? I have a query that I originally had in Access that queered from multiply databases. It did this by having those other tables in the other databases linked to the database that had the query.
Please can anyone help me for the following?
I want to merge multiple rows (eg. 3rows) into a single row with multip columns.
for eg:
data
Date Shift Reading
01-MAR-08 1 879.880
01-MAR-08 2 854.858
01-MAR-08 3 833.836
02-MAR-08 1 809.810
02-MAR-08 2 785.784
02-MAR-08 3 761.760
i want output for the above as:
Date Shift1 Shift2 Shift3
01-MAR-08 879.880 854.858 833.836
02-MAR-08 809.810 785.784 761.760
Please help me.

Hi,
I have multiple columns in a Single Table and i want to search values in different columns. My table structure is
col1 (identity PK)
col2 (varchar(max))
col3 (varchar(max))
I have created a single FULLTEXT on col2 & col3.
suppose i want to search col2='engine' and col3='toyota' i write query as
SELECT
TBL.col2,TBL.col3
FROM
TBL
INNER JOIN
CONTAINSTABLE(TBL,col2,'engine') TBL1
ON
TBL.col1=TBL1.[key]
INNER JOIN
CONTAINSTABLE(TBL,col3,'toyota') TBL2
ON
TBL.col1=TBL2.[key]
Every thing works well if database is small. But now i have 20 million records in my database. Taking an exmaple there are 5million record with col2='engine' and only 1 record with col3='toyota', it take substantial time to find 1 record.
I was thinking this i can address this issue if i merge both columns in a Single column, but i cannot figure out what format i save it in single column that i can use query to extract correct information.
for e.g.;
i was thinking to concatinate both fields like
col4= ABengineBA + ABBToyotaBBA
and in search i use
SELECT
TBL.col4
FROM
TBL
INNER JOIN
CONTAINSTABLE(TBL,col4,' "ABengineBA" AND "ABBToyotaBBA"') TBL1
ON
TBL.col1=TBL1.[key]
Result = 1 row
But it don't work in following scenario
col4= ABengineBA + ABBCorola ToyotaBBA
SELECT
TBL.col4
FROM
TBL
INNER JOIN
CONTAINSTABLE(TBL,col4,' "ABengineBA" AND "ABB*ToyotaBBA"') TBL1
ON
TBL.col1=TBL1.[key]
Result=0 Row
Any idea how i can write second query to get result?
Here is some data that will explain what I want to do:
Input Data:
Part ColorCode
A100 123
A100 456
A100 789
B100 456

Output Data:

Hi,
I'm trying to create a database that takes specific information from a number of databases on different servers to make some reporting that we have much easier.
I'm pretty new to SQL so I'm not sure of the best way to proceed. I read an article that suggested I use the OPENROWSET command. The problem is, the version of SQL that came with one of the programmes we use is limited and will not allow you to turn on the allow "Ad Hoc distributed Queries" so the SLQ statement will not execute.
I'm confused why it won't let me to connect through ODBC as I've created a web page that selects data from this database with no problems!
Here is the SQL statement that I've written to make sure it is the correct one (on the msdn library page it said that this was the ODBC connection):
SELECT a.*
FROM OPENROWSET('MSDASQL','DRIVER=(SQL Server);SERVER=APPOLOACT7;UID=sa;PWD=***************',
'SELECT * FROM MDCTestAndDev.dbo.TBL_CONTACT') AS a
I've also created the ODBC connection using the tool on Administration Tools>Data Sources ODBC
Any help would be greatly appreciated (also any ways of selecting from one database and inserting it into another will be helpfull)
Thanks
Hi!
I have 7 source databases and one target database, all using the same structure. The structure is made of 10 tables, with foreign key constraints.
I need to merge the source databases into the target (which won't have any data before that process, but will already have the correct schema), and to keep the relationships between the records.
I know how to iterate over the source databases (with SMO foreach), but I'd like to know if someone can advise the best copy method for that context in SSIS ? (I don't want to keep the primary keys, but I need to keep the relationships...)
Any pointer most welcome!
best regards and thanks

Just wondering, in DTS, can I run a SELECT script that selects from 2 different databases (both on the same server)?
I can run this in Sql Query Analyzer, but in a DTS, it doesnt accept my database name prefixes:
SELECT
a.something
FROM
DB_ONE.dbo.product a, DB_ONE.dbo.mp_brand b, DB_TWO.dbo.lk_pcat_cutover c
WHERE
a.PCat <> c.Pcat
(where DB_ONE and DB_TWO are the 2 different db names)
I have one connection to DB_ONE... does this mean I cant access DB_TWO when using this connection? I want to try and avoid using a temporay table for storing DB_TWO's data in DB_ONE... Is this possible?
Thanks,

I am trying to restore multiple .bak backup SQL database files onto a new server. However, I have found that it will not allow me to restore multiple databases at once. Is there a way to do this so that I do not have to manually upload one at a time? I tried adding all the .bak files at once to the backup device window but it only did the first one listed. It would be so much easier to restore them all at once so that I do not have to continue this manual process. I am restoring them via device.

I have two separete databases, what Ineed is that I want to make a single database of the two. Although all the table definitions of both the database are same.
I will be glad to know "how to make a single database from two" and i will be happy to see the query to insert the values from one database to another one.

Would this go a long way towards securing the data?
Database.Store(this)
Database.Delete(this)
Database.Load(this)
Where "this" is a single object mapped to a single stored procedure.
Two parameters are recommended: one to identify user, and one to specify an "action" or different SP.
Hello,
I am in the progress of designing a new section of my database and was thinking of creating a hole new database instead of just creating tables inside the database. My question is can you JOIN multiple tables in an SQL Statement from multiple databases. Ie, In the Management program I have a database called 'Convention' and another one called 'Services', inside the two databases there are many tables. Can I link say tblRegister from Convention to tblUser in Services?
Thanks

I have two databases lets say DB1 and DB2.
Schemas for both databases is same.
In both database schemas there are tables which has identity columns as primary key.
Now i want to merge these two databases in a single database say DB3.
It may also possible that some master records in both databases are common so they should not repeat in DB3
Is there any way so that i can do it quickly and as soon as possible.
Thanks in advance

Hi, I have compact sql databases which will be local on multiple users
devices. Due to space constraints, for one of the tables i have had to use
auto incrementing integer which works fine for the local database but i
would like to merge all of the users databases into a global database. The
table format can be seen below:
Code SnippetCREATE TABLE Players
(
ID UNIQUEIDENTIFIER NOT NULL PRIMARY KEY,
FirstName NVARCHAR(32),
LastName NVARCHAR(32)
);
CREATE TABLE Sessions
(
ID INTEGER NOT NULL IDENTITY,
PlayerID UNIQUEIDENTIFIER ,
SessionDateTime DATETIME,
CONSTRAINT pkSessions PRIMARY KEY (ID),
CONSTRAINT fkPlayerID FOREIGN KEY (PlayerID) REFERENCES Players(ID)
);
CREATE TABLE SessionDetail
(
SessionID INTEGER,
Time real,
Power real,
CONSTRAINT pkSessionDetail PRIMARY KEY (SessionID,StrokeTime),
CONSTRAINT fkSessionID FOREIGN KEY (SessionID) REFERENCES Sessions(ID)
);
The Players table will merge fine as GUIDs are used. However, how will the
sync capabilities of compact SQL handle the sessions table? When it pushes
the local data to the remote database will it change the Sessions.ID column
to a unique field (as no doubt lots of people will have 1, 2, 3 in their
local databases and the global database must have a unique ID), and then
transfer this changed ID back to the local database? Furthermore, if it
changes the Sessions.ID column during the merge it will also need to update
the SessionDetail.SessionID foreign key to maintain referential integrity,
is this also handled?
So my question is, how much of this sync and data merge is automated and are
there any good examples or pointers for my scenario? I cannot reasonably use
a GUID for Session.ID as there will be lots of SessionDetail entries and the
size would be far too much.
Many thanks,
Chris
