I have a varchar field which holds IDs like (1, 3, 5, 19, 23) when I order it, i get it ordered in ASCII order like (1, 19, 23, 3, 5) rather than (1, 3, 5, 19, 23) Even if I convert it to int, I won't be able to order it.
is there any way I can order a varchar field numerically?
Angel

Hi group,
I've got a table with two columns named [Year] and [Month]. They are both defined as VarChar.
Question:
Is it possible to ORDER THEM as if they where of type DateTime?
EG
select [year], [month]
from tbl_WeightedAverageGenerated
where [Year] = 2006
ORDER BY [Month]
Returns:
2006, 10
2006, 11
2006, 12
2006, 5
2006, 6
etc...
I need it to return:
2006 5
2006 6
2006 7
2006 8
2006 9
2006 10
2006 11
2006 12
Is this possible....and how??
TIA

What are some good strategic approaches to using freeform text fields fordata that needs to be queried? We have a product whose tables we can'tchange, and I need to count on a "description" field for storing a value.Two, actually. I'm thinking of adopting this convention:InvoiceNumber@VendorAcronymThere'd be a lot of vendors.Additional issue: sometimes these values would be referred to in thedescription field, and I'd need to distinguish them as referrals ratherthan as original recorded instances of the values. For that, I imaginedeither:InvoiceNumber@@VendorAcronymorInvoiceNumber&VendorAcronymInvoiceNumber//VendorAcronymetc. -- something like that.I'm just wondering if there's best practice for doing anything this stupid(hey, I'm stuck with this as our only option just now; hopefully it's onlytemporary). How to parse out whatever I end up implementing -- well, itneeds to be tractable.Thoughts?--Scott

I'm trying to CONVERT some DateTime column to VarChar in the SELECT part but still do a DateTime ORDER BY while using a UNION.
In other words, does anyone know how to make this work:
create table #temp1 (
d datetime
)
create table #temp2 (
d datetime
)
insert into #temp1(d)
select '2001-12-12' union
select '2002-11-11'
insert into #temp2(d)
select '2003-10-10' union
select '2004-09-09'
--works fine-------------------------------
select convert(varchar, d, 101) dd from #temp1
order by d
-------------------------------------------
--but can't make this work-------------------
select convert(varchar, d, 101) dd from #temp1
union select convert(varchar, d, 101) dd from #temp2
order by dd -- wrong type of sorting
--order by d-- error
--order by cast(dd as datetime) -- error
-------------------------------------------
drop table #temp1
drop table #temp2
I would really appreciate your help.

Hi, I'm starting a new application in java using JTDS jdbc driver(http://jtds.sourceforge.net) and SQLServer 2005 Express.I have to design the database from scratch and my doubt is if I have to usevarchar or nvarchar fields to store string data.Any experience about performance issues using nvarchar instead of varchar(considering that Java internally works in unicode too)?Thanks in advance,Davide.

Hi everyone.
I know, I know, it should have been a datetime from the start...but here's the problem.
I'm trying to sort by my date field but because it looks like: "04/03/2004 12:14:21 PM" it's not ordering it properly using:
ORDER BY [Date]
Are there any work arounds for this? Is there some way of doing:
ORDER BY covert(datetime, [Date], 103) or something?
Cheers
Andrew
how do you get it to sort correctly for the date? at the minute its sorting on the characters rather than actual date value
Code Snippet
INSERT INTO @TempItems (OrderID)
SELECT OrderID
FROM Orders o
INNER JOIN Customers c ON c.CustomerID = o.CustomerID
INNER JOIN Employees e ON e.EmployeeID = o.EmployeeID
ORDER BY
CASE @SortOrder --Order ASC
WHEN 0 THEN cast(OrderID as varchar(100))
WHEN 1 THEN cast(c.CompanyName as varchar(100))
WHEN 2 THEN cast(e.FirstName as varchar(100))
WHEN 3 THEN cast(o.OrderDate as varchar(100))
WHEN 4 THEN cast(o.RequiredDate as varchar(100))
WHEN 5 THEN cast(o.ShippedDate as varchar(100))
ELSE '1'
END,

I've two tables that I've made from some query subsets. Each table has a varchar field with notes/memos and I want to concatenate the fields into one long field.
The problem I'm running into is that when I run the query to check the concatenation, the field is truncated maybe 256 chars in.
I tried converting and casting the field as nvarchar 4000, and I've also done the same for the fields in the two tables, but that doesn't seem to help.
I can query for the fields from each table and none of them are truncated by themselves. It only happens after I concatenate them.
I've created a new table and inserted the results into it, but the field in it is also truncated.
Am I missing something obvious here?
I'm archiving some data. In a 2 step process.
1. Copy old data from each table in LiveDB to same table in ArchiveDB.
2. Delete the data from each table in LiveDB which is in ArchiveDB
Both DBs SIMPLE recovery mode.
Each table has a clustered PK on a single int value. In both DBs
The tables with varchar(max) columns are taking a v.long time to copy over.
IS there anything I can change in the ArchiveDB to make it run faster.
It is the insert that is taking the time. I've tried dropping the clustered PKs in ArchiveDB tables and then rebuilding afterwards but it has not made any difference. After all I am adding data to the ArchiveDB in clustered index order, so wouldn't have expected it to.
How I can change the Archive DB but cannot touch the schema/settings of Live DB.
I'm using SSIS to import data from a table (SQL) containing varchar fields. The problem is, that those varchar fields are changing over time (sometimes shrinking and sometimes expanding). I.e. from varchar(16) to varchar(20).
When I create my SSIS package, the package seem to store information about the length of each source-field. At runtime, if the field-length is larger then what the package expects an error is thown.
Is there anyway around this problem?
Oh, yeah... My destination fields are a lot wider then the source fields, so the problem is not that the varchar values doesn't fit in my destination table, but that the package expects the source to be smaller...

I have a test database that contains a varbinary(max) field and a varchar(max) field.
when I do a
Select * from test where id = xx
I get the expected results if my connection string uses
'driver=SQL Server;Server'
but these two fields return no data if I use
'driver=SQL Native Client'
the other fields in the record come back with no problems.
Is there anything special I need to do to retrieve these types of fields?

Hi, I'm trying to improve performance for a db that stores messages. The message is currently stored in an ntext field, but when I look at all the records from the past 3 months, I found that 88% are less than 1000 characters, and 97% are less than 3000 characters. I don't want to actually limit the message size, but it seems like I might get much better performance using a varchar(3000) field to hold most of the messages, and a separate text field just used for those 3% that really are long. Is this a good idea? If so, is it better to put the Message and LongMessage fields in the same table; or, have a separate table to hold the long messages? If it is in a separate table, it would need to be left joined with the message table each time messages are retrieved.Also -- I am getting about 700 new messages daily, and right now have over 150,000 messages stored. The vast majority of activity involves new messages. Is this a good situation to look at using horizontal partitioning?Thanks for any help, I don't really have anyone to discuss this with and it is really helpful to get some other views!!

I need immediate help with a query that I am trying to write. I want to sum the values in a query but the field has a type of varchar and it has decimal numbers too. So if I do the query something like that, that converts the field to int, I get the error message.
I tried converting it into real or float but I get error message on that too. I need help with adding the calculatedValues and getting there sum. I would appreciate any help with that.
Thanks

Select SUM(Convert(int, calculatedValue))

Hi, i'm new to SSIS and trying to import some csv files (comma delimited) into SQL Server. A NULL value for a CHAR column is correctly regonized as NULl in SQL Server, but a NULL value for of a mapping to a VARCHAR column in SQL Server is not recognized correctly and i get the value "'NULL'" in SQL Server (including the single comma.
Sample:
CSV file contains columns A and B. A and B contains the Text NULL.
Column A is mapped to a CHAR field, and column B is mapped to a VARCHAR field in SQL Server.
After the import, SQL has the following value: A = NULL as NULL, B 'NULL' as text.
did anyone else had this problem?
thanks so much for any help.
Hi all. I have been going round and round for the past 2 days on this and would appreciate any help. In a view select statement, I need to concat 2 varchar fields with a text field.

I'm not sure what to do. Can someone please offer some assistance? Thanks in advance! Steve

Hi.
Current development setup: Visual Studio 2005 (C# language), SQL Server 2005 Express Edition.
I am at this point changing some of my application. It stores a lot of information for times of trains. I decode a file which is text based and my times are stored in varchar(4) columns with the format "HHmm".
I am now at a stage where I need to add values to these times and perform a search based on two time values (a minimum time and maximum time).
I really need to be able to add another varchar(4) value to the times stored in my database (also varchar(4) - may look at this again in future). I have absolutely no interest in storing seconds, modifying the database to include the time colon, nor am I interested in the date portion of a time string, only the 4 digits representing the hours and minutes.
Can this be done easily in SQL server? For example:
varchar(4) of 0445 + varchar(4) of 0027 should result in the time 0512.
Similarly a varchar(4) of 2358 + varchar(4) of 0015 should result in the time 0013.
This has to be very quick to execute.
Thanks for any help you can offer!

I have a problem with ordering and I am hoping that someone is able to help.
In my table I have two fields, "requestdate" and "sentdate", and when I display the records I would like to sort by BOTH fields. I want to do this so that the full query is in order by date.
I tried:
ORDER BY requestdate, sentdate DESC
But obviously all that does is order by requestdate (which is NULL or a date) and than it will order by sentdate.
Can somebody tell me how to order by both as if they were the same field?
Thanks!

I am currently working on a PHP based website that needs to be able to drawfrom Oracle, MS SQL Server, MySQL and given time and demand other RDBMS. Itook a lot of time and care creating a flexible and solid wrapper and amdeep into coding. The only problem is a noticed VARCHAR fields being drawnfrom SQL Server 2000 are being truncated to 255 characters.I searched around php.net and found the following :Note to Win32 Users: Due to a limitation in the underlying API used by PHP(MS DbLib C API), the length of VARCHAR fields is limited to 255. If youneed to store more data, use a TEXT field instead.(http://www.php.net/manual/en/functi...ield-length.php)The only problem with this advice is Text fields seem to be limited to 16characters in length, and I am having similar results in terms of truncationwith other character based fields that can store more than 255 characters.I am using PHP 4.3.3 running on IIS using the php_mssql.dll extensions andthe functions referenced here http://www.php.net/manual/en/ref.mssql.php.What are my options here?
