Your question is confuse me .
can you post more detail ?

i mean when the query is right then data should be dispalyed and to display i need to connect
|

You really are an idiot, you have asked the same question 3 times over the last month. You have no understanding of the question you are asking and therefore cannot understand the answers so you keep repeating the question, like a 5 year old.
Remove your self from the forum until you get some more sense.

2 yyy Feb 6 2009 12:00AM
3 zzz Feb 10 2009 12:00AM
4 aaa Feb 15 2009 12:00AM
Now i want to write the query to select "IssueDate" between 02/04/2009 and 02/11/2009.
Please Can anybody help me how to write query to retrieve the data between those dates?
Thanks

I tried with that query but when i execute that query i am getting zero results but there are records in my table with that dates. I stored date value in varchar is it correct or i have to use only datetime datatype.

You need to store the date as a date.
Why people store dates in a character field is totally beyond me.
|
|
|
|

As Jamie said, mistake 1 STORE YOUR DATES AS DATE TIME.
So now that your have screwed your data you have 2 choices.
Convert the dates from varchar to datetime - this is the recommended solution
Make all the date values into datetime in your query.
Select * from table name where convert(datetime,Stupiddate) between thisdate and thathdate

Thanks for your response that query is working for my condition.
Select * from tbl_ticketinfo where convert(datetime,issuedate) between '" 02/05/2009' and '02/09/2009'
|
|
|
|
|
select * from table where issueDate BETWEEN CONVERT(varchar, '2009-02-04', 111) AND CONVERT(varchar, '2009-02-11', 111)

I tried with this query
select * from table where issueDate BETWEEN CONVERT(varchar, '2009-02-04', 111) AND CONVERT(varchar, '2009-02-11', 111)
but when i execute that query i am getting zero results but there are records in my table with that dates. I stored date value in varchar is it correct or i have to use only datetime datatype.

Wrong way - you are converting to varchar and comparing strings, you need to convert to datetime to use between!

That's a big reason not to use stored procedures.
If it's your client's system, you can't lock them out from doing silly things to it, yet you will likely be responsible for repairing any damage they do.
At best you could have a written agreement that clearly states what happens when they screw up the system.
I've was only required to write stored procedures for one client, and it as dreadful.

Not really. The user can just as easily go in and update the tables without.

Thats a more common way.
At the end of the day, if the database is on your clients server, there is very little you can do to stop them screwing it up, so having a good, watertight, written agreement of responsibilities is probably the best way - if they are fully aware of the consequences then they probably won't.

Don't give database to the users. Keep it in a secured server. Create a web service/WCF service which provides access to this database from your application. This helps to keep database isolated and prevent users from modifying the SPs.
Another alternative(worst) what I think is to create the stored procedure with WITH ENCRYPTION clause. This will make the SPs encrypted, but there is no easy way to decrypt it back. Again, this will not prevent users from dropping it.

If you use standard SQL format, I think you can copy and paste the queries. But creating views and tables in oracle and SQL server may have slightly different syntaxes. This will not work if your query has SQL server specific keywords (like top). Best way is to try it out.

Program to interfaces, always. It makes database switching easier. Read about the design patterns like provider model, etc.

I have the perfomance problem with my query, it executes every time I click on grid paging.
Here is my ms sql query(its output of Nhibernate query):
WITH query AS (SELECT TOP 235800 ROW_NUMBER() OVER (order by
cast(upper((employee0_.lastname+' '+employee0_.firstname))as nvarchar)ASC ,
cast(upper((employee0_.lastname+', '+employee0_.firstname))as nvarchar)ASC) as __hibernate_row_nr__,
employee0_.primkey as x0_0_, employee0_.firstname as x1_0_, employee0_.lastname as x2_0_,
department1_.name as x3_0_, jobtitle2_.job_title as x4_0_, workarea3_.name as x5_0_,
position4_.position_ as x6_0_, employee0_.active as x7_0_ from otis.cs_employee_ employee0_
left outer join otis.cs_department department1_ on employee0_.dept_key=department1_.primkey
left outer join otis.cs_jobtitle jobtitle2_ on employee0_.job_key=jobtitle2_.primkey
left outer join otis.cs_workarea workarea3_ on employee0_.work_key=workarea3_.primkey
left outer join otis.cs_position position4_ on employee0_.pos_key=position4_.primkey
where (employee0_.site_code!='00' )
order by cast(upper((employee0_.lastname+' '+employee0_.firstname))as nvarchar)ASC ,
cast(upper((employee0_.lastname+', '+employee0_.firstname))as nvarchar)ASC)
SELECT * FROM query WHERE __hibernate_row_nr__ > 235780 ORDER BY __hibernate_row_nr__
SELECT * FROM query WHERE __hibernate_row_nr__ > 235780 ORDER BY __hibernate_row_nr__
I have many rows in this table( more than 200 000), it executes very slow...
Would it help me if I create a stored procedure for this...or is there any other way?

Hi,
I'm not an SQL expert, however looking at your code I would add a field that holds
upper((employee0_.lastname+' '+employee0_.firstname))as nvarchar)ASC so it does not need recomputing all the time; and I would index it.
BTW: You may want to add some code to your app to make sure the new field tracks any changes to the fields it depends on.

If you can rewrite the SQL (is that permitted?). It seems that you're fetching 20 rows by scanning massive amount of rows.
dasha_pl wrote: is there any other way
As Luc pointed out, indexing will also help. It would require a bit more info about the tables (amount of rows in each table, how many rows in otis.cs_employee_ have site_code != '00' etc.)
You could try adding indexes like:
- otis.cs_employee_ (site_code, dept_key)
- all primkey columns unless they are already created as primary keys or indexed in another way
- otis.cs_employee_ (lastname)
- otis.cs_employee_ (firstname)
But as a personal opinion, the query is so twisted that if you can, you should rewrite it.
