Hi, Im new to SQL 2005.
I want to know that, any way i can use to get data from different database?
Hi,
I have a website which is designed to search for employee information. I have the search system working which does exactly what I want to, but as an added feature I want there to be a button which, when someone clicks on it, it takes whatever the previous search was and generates a set of data in XML format which is based on the results. For example:
User searches for all entries with Forename = John; Results are listed in a gridview as per expected.
User then presses button with XML on it, and page pops up with just the XML output on it, i.e. whatever results are on the gridview but in a nested XML format
<records> <record> <Forename>John</Forename> <Surname>Smith</Surname> <Email>j.smith@blah.com</Email> <Ext>1234</Ext> <DeptList>History</DeptList> </record></records>
I have created a stored procedure which will take the parameters from the search boxes and return the above information, but I don't know if this is the best way. Here it is for those interested:
CREATE PROCEDURE ps_record_SELECT_NameSurnameEmailExtDeptasXML
@Forename varchar(50),
@Surname varchar(50),
@Email varchar(50),
@Ext varchar(4),
@DeptList varchar(50)
AS
SELECT Forename, Surname, Email, Ext, DeptList
FROM dbo.record
WHERE Forename LIKE COALESCE(@Forename,Forename) AND
Surname LIKE COALESCE(@Surname,Surname) AND
Email LIKE COALESCE(@Email,Email) AND
Ext LIKE COALESCE(@Ext,Ext) AND
DeptList LIKE COALESCE(@DeptList,DeptList)
FOR XML AUTO, ELEMENTS
If someone could be kind enough to help me out with this, I'd be really grateful.
Many thanks,
Tom

View 1 Replies View RelatedBelow is code for inserting data into the database that I know works, so I thought if I replace "Insert" with "Select" I could retrieve a specific row from my database and present it in a label or text box but nothing happened. How can I retrieve a row or rows from a database using vb code and display it in a textbox? I'm using visual web developer 2008 which is similar to 2005.
Thank you.

let's say I have a table named "myTable" in a SQL database:
UniqueID
FirstName
FamilyName
1
Elizabeth
Moore
2
Chris
Lee
2
Robert
McDonald's
I want to create a SQL query should contain a parameter for example:
SELECT * FROM myTable WHERE UniqueID = @TextBox OR FirstName = @TextBox OR FamilyName = @TextBox,
and when I type in my TextBox the ' * ' character, it should retrieve the whole table...
hope anybody understood, will be happy to explain more.
Hi everyone,

I am developing a data acquistion system which monitors the amount of energy that a user consumes in different parts of a house and displays the information in real time on their computer screen. I am collecting the data through tranducers attached to the circuit breakers in the breaker box and sending the data to analog-to-digital converter channels in a MCU. I am retrieving the data from the serial port and storing it to a text file. Each line of data in the text file represents three fields which are separated by commas. I will be reading data from multiple data collection boxes so the first field is the unit number, the second fied represents the analog-to-digital converter channel number from each unit, and the third field is the data that is collected from the ATD channel. I am trying to use SSE to retrieve the data from the text file, and parse each line of data into individual columns in a databse. Then I want to be able to extract the data associated with a particular ATD channel number from the databse and display it in the appropriate text field on a windows form.
I've got the MCU programmed. I have no problem collecting the data from the serial port, and I can do the visual basic programming okay. I have absolutely no clue how to read the data into the database, continuosly read new values into the databse, and then access the stored data to update the text fields on the form. Please help if you can, I've been working on this specific problem for a couple of weeks and I'm not making any progress. Thanks.

Hello,
Before I ask a question, I am visually impaired and cannot read printed words only on a screen. I am 51 years old and have been coding professionally since I was 23 (yes that long). I have four apps on the market and run a small consultancy company in the UK and my SQL knowledge is scant. I have read two books on the subject and thought I had an idea on how SQL works.
I used to belong to another forum but they gave me a hard time so please go easy on me.
I developed an ADO app ages ago and remembered some of it ...
I have four tables (the following is a simplified version of the real thing)
MainTable (Contact data like name address etc. 23 fields)
Towns (Two fields TownUIN and TownName)
Counties (Two fields CountyUIN and CountyName)
Countries (Two fields CountryUIN and CountryName)
My database is normalised to 3NF and contains no duplicate or redundant data.
My problem ...
Sample data
Main:
MainUIN MainName MainTown
1000 Fred Bloggs 1
1001 Fred Smith 2
Towns:
TownUIN TownName
1 Bradford
2 Leeds
SELECT MainName,MainTown FROM Main WHERE MainUIN=1000 returns
'Fred Bloggs' 1 (the TownUIN)
I want ...
'Fred Bloggs' 'Bradford'
It was suggested I use
SELECT MainName,MainTown FROM Main,Towns WHERE MainUIN=1000 AND TownUIN=MainTown
This returned 'Fred Bloggs' 'Bradford' but was slow.
My question is what am I doing wrong?
I am using SQL Server 2005 Express with VB.Net 2005 on Vista Business and XP.
I am sorry my SQL knowledge is weak please dont get angry just tell me the basic thing that I do not know.

I need to retrieve the available tables in a database in SQL Server 2000. I found this command and although it works I can't figure out how to filter the results.
exec sp_tables
I don't want to return the whole list, just the tables starting with "OV" and "SV". Does SQL Server 2000 support a wildcard? Like can I have it search for "OV*" or do I have to use LIKE. Did google search with no helpful results. I remember in mySQL this was simply "SHOW Tables" but this command isn't supported in SQL Server 2000.
any help would be appreciated

Last night I face performace problems in web site. I got like 100 000 users and site fails because of sql-connections.

I close the connection every time after using the stored procedures, but nothing happened.
What do you think the problem is ??
Let us suppose that there are 900 rows in One table, and that table contains neither primary key, nor Identity column.
How can I retrieve all the roows from 201 to 250?(like the middle limits)
In oracle there is a property called RowID, but is there any such item in SQL server?
I wonder how to get top 1 row per account number. Let's say I have
--snip--
IDENTITY_ID | ACCT_NUMBER
0001 | 1111-2222
1001 | 1111-2222
2002 | 2222-0000
3003 | 2222-0000
4004 | 1111-2222
--snip--
I used the SQL-Query here
Code:
SELECT * FROM BACKUP_LOG ORDER BY IDENTITY_ID DESC
[code]
Since they are in descending order by IDENTITY_ID, so I only want to get 1 distinct account number somehow.. Like this...
[code]
4004 | 1111-2222
3003 | 2222-0000
I couldn't figure it out.
Thanks...
I have a table called Questions and I need to retrieve 10 rows of data randomly each time. If I use
SELECT TOP 10 Question FROM Questions
I'll get the same questions each time when I execute the sql statement. Is there a way to get the random data? Thanks.
