Hi,
Here`s my problem.I have 2 tables Employee and Department as follows
Employee
----------------------------------------------------------------
empid | fname | Lname | Grade | Designation | Dept_id |
----------------------------------------------------------------
Department
---------------------
Dept_id |Dept_name|
---------------------
I want to select empid,fname,lname,grade,designation,Dept_name
I know this is very simple but i am weak in joins.Pls suggest a query such that i can select the values.
|

|
|
|
Select empid, fname, LName, Grade, Desination, Dept_name from Employee JOIN department on Department.Dept_id = Employee.Dept_id
(you cqn use LEFT JOIN to get all employees, even those have Dept_Id=null.)

Hi,
I merge a dataset into another dataset in my C# application.
While doing the dataset.Merge(myParamDataSet), the event 'position change' is raised from the 'bindingsource'.
Is there a way to stop all bindingsource events before the merge & after the merge?
Best regards,
Jens

SQL Server Books Online has many examples of how to use each of the available commands and procedures.

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
Try this

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.
