hi,
I prefer http://sqlzoo.net
where one can learn by practising (online)
(explanation, examples and exercise)

Moving data from file database to sql and questions came up as to whether use of user defined types was best practice or not. What are pros and cons? Do you use them or not and why?
Will also be using these types as parameters from C# code. So welcome any specific comments regarding impact there.
Thanks,
Matt

I am trying to return only the first 10 records in sql code that has a where clause. here is my current code. Any help is appreciated.
sqlQuery = "SELECT TOP 10 PTXADDR, ZIP, X_COORD, Y_COORD, PARENT FROM JOB.PTXGIS WHERE"
sqlQuery = sqlQuery & " PTXADDR LIKE '" & addr & "%'"

In terms of getting the first 10 rows, I don't see a problem with your code.
In terms of security, you have a great big hole waiting to be exploited. You would be better reading about SQL Injection Attacks and Tips on How to Prevent Them[^]

sqlQuery += " PTXADDR LIKE '" + addr & "%'"
I just have replaced the '&' to '+'

It would be better if he didn't inject the value at all. That injection of the address opens a potentially big security hole.

can't we use the top keyword??

Select top 10 field1 from table1 where field1--Some condition order by field1

Use ALTER VIEW to recreate the view.
And, it is considered better practice to actually specify the columns you want to use. Only use SELECT * for quick-to-write ad hoc queries.

If there is a possibilty that the master table changes frequently go for cursors instead of views...

hai everybody
Am using sqlserver2000 as my back end. i want to combine 5 tables in a view and then got report from it. Is it possible? Already am combining 2 tables in a view. it was working fine. one table is master it has a composite primary key all the other containing same as a foreign key and also they have thier own primary key(Serial no)
Please Help me

Then just add the joins to the SELECT statement used to define the view. e.g.
SELECT *
FROM TableA
INNER JOIN TableB ON TableA.Key = TableB.ForeignKey
INNER JOIN TableC ON TableA.Key = TableC.ForeignKey
-- etc...

Hi,
I have a table named "FirstNames", "LastNames" and "Main". I want to enter data into the First and LastNames tables and then the identity number must be added to the Main.
I know it looks something like this but I cannot get the values into the main table.
Create Procedure dbo.Test
(
@F_FirstName varchar(20)
)
As
Insert Into FirstNames
(
F_FirstName
)
Values
(
@F_FirstName
)
Select Scope_Identity()

I'll let you fill in the gaps.
-- Declare a variable to hold the id
DECLARE @FirstNameID int
...
-- Get the ID after inserting the FirstName row
SELECT @FirstNameID = SCOPE_IDENTITY()
...
-- Insert the ID into the main table.
INSERT INTO Main(FirstNameID) VALUES(@FirstNameID)

Please help...I think I'm losing my mind.
I'm using an OleDB connection in C# to connect to a database. The table I'm trying to access tracks user session information, including the date & time of logging in and primary key of the session. I start to run into problems when the user has logged in over 68 times.
Here is the section of code:
int LastLoginRow = userDS.Tables["UserSessionInfo"].Rows.Count - 2;
sring LastLoginDateTime = userDS.Tables["UserSessionInfo"].Rows[LastLoginRow]["SessionDate"].ToString();
I checked, and it does accurately tell me what the LastLoginRow is (i.e. 90). However when it goes to grab the SessionDate information, it ALWAYS grabs row 68.
Before it gets to row 68, it works fine. Does anyone know what is going on?

The code looks OK. Might help to see the query.
Other than that, maybe all the rows after 68 have the same value in SessionDate?
Perform the query with some other tool and see what you get.

Here's some more information I've come across. There are two tables in my database, UserInfo & SessionInfo and they are connected through the field UserID, with a one-to-many relationship. When I look at the SessionInfo table alone, the sessions look as they're supposed to, the SessionPkey is ordered correctly.
However, when I expand the UserInfo row to show the related SessionInfo, at some point (around row 68 in SessionInfo) each subsequent sessioninfo is pushed on the top of the table, instead of being inserted into the bottom of the table.
So, when looking at just the SessionInfo table, the sessionPkey looks like this:
227 - 228 - 229 - 230 - ... 321 - 322 - 323 - 324
But when looking at the sessionPkey table as a subtable of the userInfo, it looks like this:
296 - 297 - 298 - 299 ... 321 - 322 - 323 - 324 - 227 - 228 - 229 - 230 ... 293 - 294 - 295
Does anyone know why this happens? I haven't changed the code used to insert into the table. Thanks.
