Searching For Textbook That Deals With Design Of Database Servers
Jul 20, 2005
Database design is well covered in undergrad CS. But does anyone know of
a textbook that deals with the design of database servers (and probably
touches on databases themselves), and perhaps deals with interpreting SQL
inquiries?
The motivation for this is that I wish to write a database server for a
proprietary
operating system (it resembles POSIX, but is not completely compliant)
for an embedded processor system that exchanges queries from clients also
employing embedded processors. Stored data is all in one place.
I'm a little familiar with the MySQL source code, but I don't
wish to replicate something that complex. The sort of investment
I'm talking about should involve no more than three man, er, person-months
by an experienced C++ programmer with plenty of experience in systems
and database programming for both Microsoft and Linux platforms.

Hello All,
I’m looking for a solution to timeouts that occur when I’m executing a stored procedure from my web application. Most of the SPs will run from 3 to 15 minutes, and, unfortunately, modifying/optimizing them isn’t an option at the moment. I tried setting the CommandTimeout to 0 with no luck. Unless, I didn’t use it properly. Here’s my code: 1
2 try
3 {
4 string dbConn = ConfigurationManager.ConnectionStrings["ConStringNTMTLDEV"].ToString();
5 OleDbConnection connection = new OleDbConnection(dbConn);
6
7 lbl_SearchResult.Text = dbConn;
8
9 //OleDbDataAdapter adapter = new OleDbDataAdapter();
10 OleDbCommand cmd = new OleDbCommand("SP_CallHistoryLookUp", connection);
11 cmd.CommandType = CommandType.StoredProcedure;
12
13 cmd.Parameters.Add(new OleDbParameter("@phoneNumber", "1234567890"));
14 cmd.Parameters.Add(new OleDbParameter("@email", "123@123.com"));
15 cmd.Parameters.Add(new OleDbParameter("@WebUser", "123"));
16 connection.Open();
17 cmd.CommandTimeout = 0;
18 cmd.ExecuteNonQuery();
19 cmd.Dispose();
20 connection.Close();
21 }catch(OleDbException ex)
22 {
23 lbl_SearchResult.Text += "<br/> Something went wrong </br>";
24 lbl_SearchResult.Text += ex.Message.ToString();
25 }
26

Is it possible to launch a stored procedure and close the connection without waiting for a result?Would the stored procedure still run on the SQL server? I’m using MSSQL 7. Would you have any examples that would solve this problem? Thank you for your help.
R.

We are planning to move all of our System Center Databases that reside on front end servers to each system center application to a centrally located SQL 2012 server. We'd like to centralize everything and have our DBA care for the server. here is our setup:
SCOM has 1 monitoring and 1 Data warehouse server. SCCM has 1 server with all roles on it. DPM database is on the same server as Application. Same with SCVMM. I have 2 questions regarding this move:
1. Can I have all these databases running on 1 SQL instance?
2. Is there a best practice document that highlights steps and "gotchyas"

Ok, I'm doing a football database for fixtures and stuff. The problem I am having is that in a fixture, there is both a home, and an away team. The tables as a result are something like this:
-------
Fixture
-------
fix_id
fix_date
fix_played
----
Team
----
tem_id
tem_name
-----------
TeamFixture
-----------
fix_id
tem_id
homeorawayteam
goals
It's not exactly like that, but you get the point. The question is, can I do a fixture query which results in one record per fixture, showing both teams details. The first in a hometeam field and the second in an away team field.
Fixture contains the details about the fixture like date and fixture id and has it been played
Team contains team info like team id, name, associated graphic
TeamFixture is the table which links the fixture to it's home and away team.
TeamFixture exists to prevent a many to many type relationship.
Make sense? Sorry if this turns out to be really easy, just can't get my head around it at the mo!

Hi,
This is the first database I have ever created, so please bear with me.
I've created a simple database with 1 column and about 80,000 rows. In each row is a word (basically a dictionary without definitions).
I have written a query which works, and is, as follows (you'll notice that i'm not the most original of people)
SELECT
word
FROM dbo.words
WHERE word= 'hello'
This finds the word hello.
In excel I have a row with 25 letters and then a column with every single combination of letters from 3 to 10 lettered words. (It makes sense to me!)
This comes back with a lot of possibilities (thousands), but is great in the sense that when I change any of the 25 letters the entire column automatically updates.
What I am trying to do is then take all of these possibilities and compare them against the dictionary.
I have written a line in excel which automatically creates a cell a bit like this, for the first couple of thousand possibilities:
WHERE word= 'abc' or word= 'fgm' or word= 'klm' or word= 'pqr' or word= 'uvw' or word= 'bcd' or word= 'ghi' or word= 'lmn' or word= 'qrs' or word= 'vwx'
I then whack this into the query from above and off it goes. The only problem is that the search takes ages, and because of limitations in excel I can't put more than a thousand or so words in the cell.
I am certain there is a faster way of searching through all the possibilities, any help would be much appreciated.
Thanks in advance

Im trying to do a database query based on user input from a text field. I pulled apart the string that was
entered into the search form and stored it in textArray. The problem I
am having is when I include commmon words such as the, near, view and so
on into the search field I end up with zero results. when I only search
for less common words such as rocky and argentina for example the search
works fine. at first I thought that maybe it was generating too many
results and was screwing up but when i search for rocky it works and
when i search for near rocky it doesnt.
I realize the code might not be the most efficient but here it is...
@searches_pages, @searches = paginate(:searches, :per_page => 10,
:conditions => getSearch(textArray,params[:country]))
def getSearch(textArray,selectedCountry )
result = []
string = ""
if selectedCountry != "Optional Field"
string << "country = (?) and "
end
textArray.each do |x|
if textArray[textArray.length - 1] == x
string << "match(country,caption, keywords, notes) against
(?) "
else
string << "match(country, caption, keywords, notes) against
(?) and "
end
end
result << string
if selectedCountry != "Optional Field"
result << selectedCountry
end
textArray.each do |x|
result << x
end
result
end
Im not sure if i supplied enough information but I am trying to finish
this project soon so any type of responses would help. Also, if there
is an easier way to do an sql search based off of what is entered into
the search field please let me know. The reason I did this is because I
wasn't sure how many words the user would be entering into the field.
And without knowing this I could not hard code the conditions => so I
wrote a helper method.

OK I have a search page and the query that is being send from the search box is
"SELECT * FROM [problems] WHERE ((problemBody LIKE '%' + @search_id + '%')OR @search_id IS NULL)"
Now say I have in the column for problemBody "Search the database" If i Type in the search field search the, or the database, or data, ot search, or even just s it will bring back records, But if I do not use exact keywords such as "search database" it will not bring back anything. How do I make it search all the keywords used?? like a normal search engine.

I am finishing up my senior project application but I wanted to include a search function that would search all the tables of the database and look for matching text that is input by the user. I am not really looking for code or anything just some pointers in the right direction. I was thinking that I would have to create a view that is populated by a sub-query. My problem is how do I output the results of a search of every relevent table in the database when they all have very different column names and data types? Im guessing column aliases are involved somehow but I am not really sure where I should start. Any suggestions would be appreciated.

I've been given read access to a database and I also am looking at a GUI which draws data from the database. I am trying to map the results I see from the GUI to find the columns that the data is in... So.. big database, takes a long time to search the entire thing so I try to narrow it down by the following:
Code:
select * from information_schema.columns where table_schema = 'db19' and table_catalog = 'masterdb' and
table_name in(select table_name from information_schema.tables where table_type = 'base table' and table_catalog = 'masterdb' and table_schema = 'db19' and data_type in ('text' and 'varchar'))
This essentially gives me a list of tables and columns whos data type is either text or varchar. Once I have this list... I then run the following on each:
Code:
select top 1 [col_name] from [table_name] where [col_name] like ' (here is the value I want to search) '
So this runs through each table, looking to see if a value exists and if so, prints the result.
I am then left with a much much smaller list that I can manually look through and find the one I am looking to specifically find.
Is it possible to do this running only one query... where the output gives me all the columns in with a specific data type that contain a value I enter Anything else to make this more efficient
I am aware that there are data mining programs that could probably do this however I only have read access on the database which often causes a problem. The application I am using is "Aqua Data Studio" ....

Hi, this is my first post on these forums, so please excuse me if this topic has already been covered.
I'm currently working in a power station for student vacation work placement. I need to export data from a database that gets it's data from machinery and inputs out in the plant. The machines that provide this input put it into a database, and I need to find the relevant data to export.
My problem is that, in some cases, the sample data that i'm given may be under different field names, in a completely unrelated table. I was looking for a way to search the entire database (250+ tables) for a certain string, so I can find where it is in the database, and run queries on the table it originates from. For example:
My sample data shows me that I have an object with the ID Y03A3DEA_TH1. I know this ID will occur somewhere else in the database, but i'm just not sure where.
If anyone knows of any way that I can search the entire database for specific data, either using tools in MS SQL 2000, or 3rd party apps, i would greatly appreciate their help.
Thanks a lot,
Jack Smith

Hi,
I am building a website in ASP.net C# for a university project, and would like to search a table (Member) for a field (UserName) using a session variable Session["sUserName"]. If that field is null, then I would like to insert that session variable into the field to start to create a new user. However, I am getting errors saying that I am using invalid expression terms. My code is;
//Create the Command, passing in the SQL statement and the ConnectionString queryString = "SELECT UserName FROM Member WHERE (UserName = @myUsername); ";
SqlCommand cmd = new SqlCommand(queryString, sqlConn);cmd.Parameters.Add(new SqlParameter("@myUsername", Convert.ToString(Session["sUserName"])));
//If UserName is null, display confirmation, else display errorif (UserName == null) ;
{UserNameCheckLabel.Text = "Username okay";
String queryString = "INSERT INTO Member (UserName) VALUES(@myUsername); ";SqlCommand cmd = new SqlCommand(queryString, sqlConn); cmd.Parameters.Add(new SqlParameter("@myUsername", Convert.ToString(Session["sUserName"])));
}else;
{UserNameCheckLabel.Text = "That username is in use";
}
I have a feeling I should be checking the database for the UserName, but I'm not sure whether to put this in the SELECT statement part or as a method... I would be most grateful for any advice!
Many thanks,
Chima

Hi!
I found a problem while retrieving/searching/filtering Myanmar Text with a Select Statement, In a Myanmar Text table there in a column called HeadWords.
It's Sample Data
HWID,HeadWords
1,|က|
2,|ကာ|
3,|ကိ|
4,|ကီ|
5,|ကဲ|
I want to make the following search:
SELECT * FROM TableName WHERE HeadWords LIKE '%|က|%' this should give me all entries that have a "|က|" *ANY* place in the HeadWords column. Right?
However, it gives me unproper results. you may see last two records have 2 characters between pipe(|).
HWID,HeadWords
1,|က|
3,|ကိ|
5,|ကဲ|
Since the wildcard character % means no or all characters it should work. And I've tried pipe, comma, forward slash and back slash.
The problem only seems to occur when the wildcard character is used for the any part of character. Let me know alternative way to search that matters. I've tried in MSAccess. There are same problem like MSSQL.
It's any problem in searching support for National Characters (UTF8). I've tried in OpenOffice Database with those data.
It's work fine.
If you not see Myanmar characters, please download fonts from http://www.fontmm.com/font_downloads.htm
Does anybody have an explanation to this, please let me know.
Thanks in advance!

Hello everyone,I have a webcontrol that uses database-structures alot, it uses the system tables in SQL to read column information from tables. To ease the load of the SQL server I have a property that stores this information in a cache and everything works fine.I am doing some research to find if there are anyway to get information from the SQL server that the structure from a table has changed.I want to know if a column or table has changed any values, like datatype, name, properties, etc.Any suggestions out there ?!

I have a system that basically stores a database within a database (I'msure lots have you have done this before in some form or another).At the end of the day, I'm storing the actual data generically in acolumn of type nvarchar(4000), but I want to add support for unlimitedtext. I want to do this in a smart fashion. Right now I am leaningtowards putting 2 nullable Value fields:ValueLong ntext nullableValueShort nvarchar(4000) nullableand dynamically storing the info in one or the other depending on thesize. ASP.NET does this exact very thing in it's Session State model;look at the ASPStateTempSessions table. This table has both aSessionItemShort of type varbinary (7000) and a SessionItemLong of typeImage.My question is, is it better to user varbinary (7000) and Image? I'mthinking maybe I should go down this path, simply because ASP.NET does,but I don't really know why. Does anyone know what would be the benifitof using varbinary and Image datatypes? If it's just to allow saving ofbinary data, then I don't really need that right now (and I don't thinkASP.NET does either). Are there any other reasons?thanks,dave

Hi All,
I am designing database where few of the master tables will reside in different database or in case different server. Scenario is
Server "A" with Database "A" may host the "Accounts" table.
Server "B" with Database "B" may host the "Product" table.
I am designing database "Project" which will hosted in Server "A".
My application requires this master tables [readonly access] as data inserted in my application refers this tables. Also there are reports to be generated which refer this tables.
How do i design my database and sql queries?
I am thinking of approach of having equivalent tables created in my database and writing service which keep tables in my database in sync. This will ensure good perfomance during transaction and reports as they will need to refer this table locally as opposed to different database or different server.
Any thoughts on above approach?? or any better/standard way for such scenarios ?
Thanks in Advance. Your inputs will be of great help.

Hello:
My client has a db with the following structure:
Online US Searchable Map of the 50 US States. Users search criteria is the following: Query records by selecting state, county, then record. Each County table has 10-20 tables. All databases combined = 500MB and TLogs = 100MB.
How would you re-design a relational DB where users could query data by state-county-record. Currenty the DB's are created by the County of each state which creates hundreds of DB's in SQLServer with no realtionship to each US state. What would be the best design to ensure good performance, data integrity and maintenance? Would you create 1 DB with all 50 states, create 4 DB's and divide by region(N,S,E,W), 50 DB's of each state or leave it as is with each county it's on DB? Any suggestions would be appreciated.
thx

I am trying to create a trigger on table A existing in Database A on Server A which on insert,update,delete would reflect these changes on table B in DatabaseB on Server B. I wrote the following syntax but it doesnt work
CREATE trigger trg_upd_tableA
On dbo.tableA
for UPDATE
as
--update the fields
declare @cust_no varchar
SELECT @cust_no = cust_no FROM inserted
update ServerB.DatabaseB.dbo.tableB
set
entity_type_cd = 'MFG',
cust_no = 6699,
name_en = 'NOVARTIS',
status ='A',
create_date=getdate()
,modify_date=getdate()
where cust_no= @cust_no
I get the error below
Another user has modified the contents of this table or view ; the database row you are modifying no longer exists in the database
Database Error: '[Microsoft][ODBC SQL Server Driver][SQL Server] MSDTC on server 'DatabaseB' is unavailable'
I would like anyone to reply to me as soon as possible please because i need the solution urgently
Thanks alot in advance,
Noha

I am attempting to move a User Database from the Production Server to a Training Server. What is the best/most simplistic way for me to accomplish this task and place this copying action on a schedule of say "every saturday morning @ 7am"
I tried the "Copy Database Wizard" within Enterprise Manager and it successfully copies the database, however when I try to schedule it to happen at a different time...it does not copy the database. It seems to only work when I tell it to perform this action now.
Please help.
Thanks,
JC
