if i use varchar(max) instead of varchar(50), and use "chandra" only , then will both give the same performance.

I assume your question is 'will they give the same performance?' - if so the answer is yes.

well,
i use varchar(max) for very long strings, that i don´t know the size
i use varchar(50) if i know the string never goes of that border
var means variable, so is from 0 to 50.
if you know you only need 3 chars you use char(3)
if you need 0,1,2 or 3 chars you use varchar(3)

OK, so I have a table of businesses. Then I have a table of contacts. So, I have many contacts for the one business. I want to do a search, and use a contact name as a possible search. However, I don't ever want to return the same business more than once. So, I want to return each business that matches at least one contact, with any contact that matches. I've tried putting in a subquery so that I select the top 1 contact for a business, but I can't find a way to write SQL that works.
select
c.IDClient, c.Company, con.LastName + ', ' + con.FirstName as Contact, c.Phone, c.Fax
from tbl_client c
inner join tbl_client_contacts cc on cc.IDClient = c.IDClient
inner join tbl_contact con on con.IDContact = cc.IDContact
where con.IDContact = (select top 1 IDContact from tbl_client_contacts ccc where ccc.IDClient = c.IDClient)

SQL query seems ok.Your query don't return data or what?
Have you try to specify table name for column IDContact inside subquery?
<br />
select<br />
c.IDClient, c.Company, con.LastName + ', ' + con.FirstName as Contact, c.Phone, c.Fax<br />
from tbl_client c<br />
inner join tbl_client_contacts cc on cc.IDClient = c.IDClient<br />
inner join tbl_contact con on con.IDContact = cc.IDContact<br />
where con.IDContact = (select top 1 ccc.IDContact from tbl_client_contacts ccc where ccc.IDClient = c.IDClient)
Hope it will help.

Hi,
I am using sql server 2005 and ASP .Net 2.0, VS 2005.
When I increased a parameter in Stored Procedure and in application, and again running the application it throws an error that, Parameters does not match with the stored procedure parameters.
All i have to do is restart the machine and again run the application. Then it does not throw the error and it works fine with the extra parameter in application as well as in storedproc.
I am unable to understand what is the exact problem, that i have to restart the machine and then it accepts the changes

I think you'll find it has to do with the way you are running the ASP for development, sound like ASP is cacheing the footprint and rebooting clears out the chache.
Try asking in the ASP forum, they may be more helpful.

Hi,
I saved a data import task to a SSIS package in MSDB. SQL Server 2005.
Now how can I access that again??? I want to make an automatic task to upload files from a folder to tables??
Dont we have something easy and useful like DTS in SQL server 2005???

I can understand your angst, I knew DTS, it worked well and it was fairly simple. But they (MS) have moved on and inflicted us with SSIS, there is no going back.
Alternatively you can write your own ETL solution. This is what we did rather than use SSIS.

hi,
i made some procedures that ends in a edit process(edit,add,delete) or nothing, like this:
if not exists(select * from mytable where id = @whatever)
begin
...edit something
end
--else
--begin
--... do nothing here
--end
So, i trigger this stuff in c#(whatever event doesn´t matter) and i have to display info msg in label, like this:
OK: sale added
ERROR: can´t delete, client in sales table
OK, sometimes i don´t know where it enters/falls, i think on counting rows in datagridview to check a delete or add for exemple, on a edit i use a compare(C# datagridview)
i´m thinking on creating a trigger or an extra table to feed the info label, i don´t know really
(no need to place code, just ideas)
Thanks

Could you break this question to pieces, since there is mices t-sql and user interface components. I take it you want to achieve some kind of error handling, but I'm not sure

Ok I see,
Could you use output parameters in sp?
Assign the output parameter to something during the execution, based on what has happened inside the sp. Then after executing the sp from c# you should have a value in that parameter. Extract it and show it in the label.
I typically use enum types (mainly for localization reasons) in c# in similar situations (I just use the same numbers in sp than in c#) but if you just want to return text, there's no need to use numbers.

I'm not much of an SQL coder, but don't know where else to go. I have a small script that I would like to have modified. Right now it is a 'hard coded' date, meaning that I have to manually go in each time and make changes to it in order to pull the date range I want. I want to be able to have it run automatically (using additional software) for the previous month. Example: On Oct 1, 2008, I would produce a report, using this script, for the previous month, Sept 1 2008 - Sept 30 2008. Can it be done? I have copied the script below:
DECLARE @DateFrom VARCHAR(15)
DECLARE @DateTo VARCHAR(15)
--Date Selection
SET @DateFrom = '01/04/2008' --MM/DD/YYYY
SET @DateTo = '01/04/2008' --MM/DD/YYYY
select
Primary_InsPlanName AS [Plan Name],
DoctorName AS [Doctor Name],
CPTCode AS [CPT Code],
Modifier AS Modifier,
sum (ChargeCount) AS [Total Units],
SUM (ChargeAmount) AS [Total Billed Amount]
from vwIR_OBJ_stdCharges
--Insurance Plan Selection
where primary_insPlanNum IN ('300','303','449','455','473','497','504','530','2181','2303','10018','13422','13483','13671')
AND cast(CONVERT(VARCHAR(10),PostDate,101) as dateTime) >= cast(CONVERT(VARCHAR(10), @DateFrom, 101) as dateTime)
AND cast(CONVERT(VARCHAR(10),PostDate,101) as dateTime) <= cast(CONVERT(VARCHAR(10), @DateTo, 101) as dateTime)
group by
Primary_InsPlanName,
DoctorName,
CPTCode,
Modifier
Order by
Primary_InsPlanName,
DoctorName,
CPTCode,
Modifier
Any advice is appreciated. Thanks!!

hi,
forget the code, what do you want to do???
listen, don´t set date, use getdate(), datediff() or dateadd() function often

It's a report that right now I have to manually go in and set the dates. It's always run on the first day of the month and the data we are looking for is the previous month's data (i.e., October 1st, I will run it for 9/1/08-9/30/08).

You can calculate the From and To days in your sp.
First day of previous month:
SELECT DATEADD(MONTH, -1, DATEADD(DAY, - DAY(getdate()) + 1, cast(Floor(cast(GETDATE() AS float)) AS datetime)))
Last day of previous month:
SELECT DATEADD(s, -1 ,DATEADD(DAY, -DATEPART(DAY, getdate()) + 1, cast(Floor(cast(GETDATE() AS float)) AS datetime)))

Thanks for the info. My question would be where in the original script would your statement go? Sorry, I'm a SQL idiot. . .
|

|

DECLARE @DateFrom VARCHAR(15)
DECLARE @DateTo VARCHAR(15)
SELECT @DateFrom = DATEADD(MONTH, -1, DATEADD(DAY, - DAY(getdate()) + 1, cast(Floor(cast(GETDATE() AS float)) AS datetime)))
SELECT @DateTo = DATEADD(s, -1 ,DATEADD(DAY, -DATEPART(DAY, getdate()) + 1, cast(Floor(cast(GETDATE() AS float)) AS datetime)))
