It does not work like this here.
Here is what is expected of enquirers:
1. TRY first what you want to do! You may find that it's not that hard.
2. Formulate what was done by you that looks like an issue/not working.
Try them and tell if you face issues.
Members will be more than happy to help like this.

declare @i int
set @i=1
select Holiday_Name from Holiday where Holiday_On = DATEADD(day,@i,CONVERT(date,GETDATE()))
i am trying to retrieve holidays list from db.but i am unable to retrieve ....can anyone tell me pls what is the error in my query
|

Assuming you are using SQL Server - take your code to SSMS and test it, then tell us that the error is.
If there is no error then check there is a record to get.
Never underestimate the power of human stupidity

i don't know how to use if...exists
i am new to asp.net & database as well
my requirement is to get 3 consecutive working days
declare @i int
declare @count int
set @i=0
set @count=0
while(@count <= 3)
begin
1) select Holiday_Name from Holiday where Holiday_On = DATEADD(day,@i,CONVERT(date,GETDATE()))
the above statement is to check whether holiday exists
2) IF DATEPART(day, DATEADD(day,@i,CONVERT(date,GETDATE()))) = 7 OR DATEPART(dw, DATEADD(day,@i,CONVERT(date,GETDATE()))) = 1
the 2nd statement is to check whether weekend or not
set @i = @i + 1
if there no holiday and not weekend then only the following code is executed
set @count = @count + 1
here i have to retrieve the date...i don't know how to get the date...because i vil get 3 dates...
end
actually i no need to select holiday name in 1)statement...there i am checking for holiday..

Hi,
I am using the below bcp command to export the binary files from the filestream db and all other files are seems to be exported fine (i.e. txt, pdf, rtf, image files & etc) except docx, xlsx & pptx files. I am able to export these files (i.e. docx, xlsx & pptx) but I am getting a warning/error message when opening those files and then it opens the file properly.
BCP "SELECT content FROM [dbo].[Contents] WHERE ID=1" queryout "C:\Temp\" -T -S (local) -f C:\Temp\files.fmt
I am getting the below message when opening docx, xlsx & pptx files:
XLSX - Excel found unreadable content and Do you want to recover the contents of this document? DOCX - The file test.docx cannot be opened bcos there are problems with the content and then Excel found unreadable content and Do you want to recover the contents of this document?
Also, I have this in my files.fmt file:
10.0
1
1 SQLBINARY 0 0 "\t" 1 content ""
Any help will be much appreciated.

Your project is in deep trouble.

I don't know how you managed to get this job, but I hope your boss does not belong to CodeProject. I would suggest you spend the rest of the weekend using Google to research "e-commerce solutions".
Use the best guess

You are in trouble.
You need a basic understanding of the following skills
- Reading and understanding requirements.
- Creating designs
- Creating data models
- Creating databases
And I expect that you are going to also need the following skills
- Internet Security
- Web design
- Basic SQL
- Intermediate Database management and SQL
- Basic user security
- Basic business retail knowledge
You could probably start by learning how to create databases, create tables and use SQL to access them. That would probably take a week.
Then learn about business retail and improve your requirement reading skills. No idea how long that will take you.
The two above together can then be used to create some tables that are at least something like what is needed for the project.

OK, so as I understand it the db_accessadmin role got merged into db_securityadmin in recent versions of SQL server? This is fine, it's better this way.
My question is, when did it happen? I try to cater for all reasonable flavours of SQL server in my system, I recently took great joy in removing support for SQL 7 (The last client using it paid me to migrate their data to 2008r2 via 2005).
Now I'm trying to set up a login with both db_accessadmin & db_securityadmin rights. Or just db_securityadmin, if appropriate. So I need to know which release they merge in. Google is useless on this, so is MSDN.
I could just try to grant the right and suppress the error if it fails, On Error resume next anyone 
One day we'll look back on this and plow into a parked car.

 well now I feel suitably daft, this is ancient history.

I have a SQL Server project that I'm currently adding code to using SSMSE2k8 and beside the fact that this is all TSQL, there's this creep that's occuring in the facility. Namely the .xml. Now, here's the more technical side of TSQL as related to XML, using a FOR XML PATH juncture. I can do a basic SELECT query and get output of xml (pseudo output really because ... this is the creep; in ssmse that's as far as development WENT) but I'm constrained by all these substitutions in he editor:
<?xml version="1.0" encoding="UTF-8"?> <kml xmlns="http://www.opengis.net/kml/2.2"> <Document>
Control characters!
What's the purpose of eliminating right & left arrows ... anyway?
And how might I preserve them and keep the phantom formatter from invading my ... "style" (if you could call it that)?
[Edit]
And wouldn't you know it? This phantom has got me here in a paste! That tagged string up there in the midst of my paragraph is suposed to be:
<?xml version="1.0" encoding="UTF-8"?> <kml xmlns="http://www.opengis.net/kml/2.2"> <Document>
[End edit]

Wow,
Could have knocked me over with a feather ... the reason that my editor (was) going south was because of the type I had used to reassign parsed lines of singleline .xml while striking it up as data in a table!.
[nvarchar](MAX) throws (bad use of an alliteration) the phantom formatter into overdrive, while [xml] is silently overlooked. Thus arrows are preserved.
|
|
|
|
|
To avoid XML Escape Characters (" ",' '< <> >& &)
Use this:
FOR XML PATH(''), TYPE).value('.', 'VARCHAR(MAX)')
|
|
|
|
|
Have you got the result...
|
|
|
|
|
My bad,
The original code that I used as the query:
SELECT [xmliform] AS 'data()' FROM [database].[xml].[tblXMLAsTypeNvarchar] FOR XML PATH('')
So, as you can see, an editor will try to format anything from a table where the type is [nvarchar] using it's xml parser when I specify "FOR XML PATH" regardless of how bad I "want" it as xml. And that is with substituted control characters.

hi to all
i lock a table in sql with belwo query
begin tran
select * from BML.LoanApplication with(TABLOCKX)
now i want to unlock this table but i cant
.
i can read from this table by nolock but i want to unlock this table
any help can be usefule
|

First of all, locking has little use when selecting. Second, the lock is released as soon as the statement completes.
What did you think it does?

If you can't read my code, try converting it here[^]
