Creating Datatypes In SQL SERVER 2005
Mar 14, 2008In oracle we create abstract datatypes using the command, for example,
CREATE TYPE address as object
(Street varchar2(50),
cuty varchar2(25));
Can this be done in SQL SERVER 2005? I am new to SQL SERVER 2005. Please help me out giving out the proper syntax alongwith an example.

May 24, 2007Hello,
Could someone give me the difference between "Sql Mobile 2005" and "Sql Compact 2005".
At first I thought they were the same, that this was just something of the change in naming the server has had the last months.
My first guess was that Mobile would be the new one, but I have 'accidently' downloaded the Compact and what seems the System.data.SqlServerCE.dll is newer.
So is there a difference?
If yes, what are they.
If not, is the "compact" then the latest version and the name to be used (since on the site only "mobile" is mentioned).

How To Tell Difference Between Sql 2005 Express

Howcan I tell which version I have installed ?
Strange Difference Between Sql 2002 And 2005.
Dec 5, 2007hi,
I just realized that this must be a difference between sql server 2000 and 2005.
For example, the query is like this:
declare @n int
set @n = -1
select @n = employeeid from employees where companyID=1 and idnumber='1-1'
--select @n
if(@n is null)
......
If there is no such employee, in 20002, @n will be null, but in 2005, @n is -1, not null. Am I right?
So, for this piece, I have to do twice on the same where, like
if(exists(select * from employees where companyID=1 and idnumber='1-1'))
select @n=employeeid from employees where companyID=1 and idnumber='1-1'
else
set @n = null
Any better way?
Thanks.

2000 To 2005 Query Processng Difference?
Mar 8, 2007I found an unusual problem between 2000 and 2005 I haven't been ableto decipher from any documentation.The query structure is as follows:select *fromtableA ajointableB b ON a.somekey = b.somekeywherea.type = 'A'and datediff(yyyy, b.someDateField, getdate()) betweena.lowboundary and a.highboundarySome basic facts about the elements and data. The low and high-boundary fields are varchar datatypes. In 2005 (regardless ofcompatibility type I run the database under), the query evaluates theBETWEEN and errors out due to the fact that it is evaluating theDATEDIFF as an integer and finds a non-integer entry in eitherlowboundary or highboundary. I understand and expect this behavior.Obviously, changing the result of the DATEDIFF function to varcharallows the operation to go forth.The odd thing is that there is no "a.type = 'A' " entry, thus thequery wouldn't return anything. In 2000, it seems as though theengine is evaluating the type = 'A' and short-circuiting and in 2005,it is trying to evaluate the entire query OR is there an implicitconversion occuring in 2000 and not in 2005?As I mentioned, the compatibility mode doesn't change how this reacts,but running this on a native 2000 server allows this to happen. Thisparticular code isn't the problem, it's what we might have to contendwith when we migrate this through. Sure, we're going to performregression testing, but I'm concerned about what we would miss.Thanks for any replies.

Find Difference In Month And Year In Sql Server 2005
Jun 17, 2008--find day,month,year

-- --for month select datediff(m,'01 jun 2006',getdate())
-- --for year select datediff(year,'01 jun 2006',getdate())
above working fine but suppose difference is 1 year 4 month and 2 month 15 days then It's giving 1 year and 2 month respectively.
but I want completely so I can use this in case of expired user in my project.
User can be expired in 1 month,3 month and 1 year. So I'm not able to recognize.

Problem: Performance Difference Between MSDE And SQL Express 2005
Feb 4, 2007Hello, all, I started out thinking my problems were elsewhere but as Ihave worked through this I have isolated my problem, currently, as adifference between MSDE and SQL Express 2005 (I'll just call itExpress for simplicity).I have, to try to simplify things, put the exact same DB on twosystems, one running MSDE and one running Express. Both have 2 Ghzprocessors (one Intel, one AMD), both have a decent amount of RAM(Intel system has 1 GB, AMD system has 512 MB), and plenty of GB offree disk space. MSDE is running on the Intel system, Express isrunning on the AMD system. To keep things fair I use the exact sameDB's and query on both systems. The DB's were created on MSDE so Isp_detach_db'd them from MSDE and then sp_attach_db'd them to Express(this is how MS says to do a "side-by-side" upgrade, so it'sacceptable to do so). After fighting problems in performancedifferences in different situations I have narrowed the problem downto this:Executing a simple select statement with join clause on the databasesyields a difference in execution time that is quite great. Using theExpress Management program I can run the query against either system(MSDE or Express, the two systems are connected via crossover cable toeliminate any network problems/issues). When running the queryagainst the MSDE system (which is over the network) I consistently get<20 ms response times on the query. When running the query againstthe Express installation (which is in shared memory) I consistentlyget 700 ms or longer response times. Both times are for the TotalExecution Time.The query is simply this: select db1.* from db1.owner.tablename as db1inner join db2.owner.tablename as db2 on db1.pkey = db2.someid wheredb1.criteria = 3So, gimme all the columns from one table in one DB (local to theinstallation), matching the records in another DB (also local to theinstallation), where one field in the first db matches a field in thesecond db and where, in the first db, one column value = 3.The first table has a total record count of 630 records of which only12 match the where clause. The second table has a total record countof about 2,700 of which only 12 match up on the 12 out of 630.Even though the data is the same and I've done the detach and attach,and even done the sp_updatestats, the difference in execution time isremarkable, in a bad way.Checking the Execution Plan reveals that both queries have the samesteps, but, on the MSDE system the largest consumer in the process isthe Clustered Index Scan of the 630 record table (DB1 in my queryexample), using 85%. The next big consumer is a Clustered Index Seekagainst the other table (2,700 rows), using 15%.The Execution Plan against the Express system reveals basically theexact opposite: 27% going to the Clustered Index Scan of the 630record DB1, and 72% going to the Clustered Index Seek of the 2,700record DB2.I'm sorry to be stupid but I have this information but I don't knowwhat to do with it. The best that I can tell from this is that thisis the source of my problems. My problems are that on my currentsystems that my clients use the data is returned to them faster thanthey can click the mouse and that the new system (that is, when theychose (or are forced by attrition) to move to Vista and thus Express2005) the screen pop is like 1.5 seconds. This creates poor userexperience. Worse, one process I allow the users to do goes fromtaking 14-30 seconds to over 4 minutes (all on the same machine withthe same OS and version of my program, so it's not a machine or OS ormy app problem).Anyway, I hope someone can shed some light on this now that I've paredit down some.Thanks in advance.--HC

Aug 1, 2007Hi,
I'm having an issue with a query I'm running on Sql Server 2005. It's a semi-complex query involving an in-line table function and several left outer joins which are joined on to the results of the function call. Two of the left outer joins are then qualified in a where clause of the form where table.Col is not null; the idea is that the final result set contains data that has no match in those two tables.
The problem revolves around a where clause in the function and the last left outer join (ie, one of the ones qualified with where not null). When I alter the where clause of the function to further restrict the result set the function returns, the query times shoots up from 1 second to roughly 2-3 minutes. Note that the time the function takes to complete is not affected. The difference in time is purely down to what the query does with the results the function provides. Also note that the change to the where clause provides a subset of the original data; it does not add any more data (it actually restricts the original resultset by roughly 1000 rows).
I can bring the query speed back down again by removing the last left outer join - this join takes one of the columns from the function, and joins it to a small table - 924 rows. So it appears that this particular join is the cause of the issue, but only when using the resultset generated from the modified function query.
Now, as the thread title alludes, Sql Server 2000 and 2005 handle this differently, or appear to. When I execute this same query on a Sql 2000 machine, there's no apparent time differences, and the data that is returned is as expected. Does anyone have any suggestions as to what might be causing this and how I can fix it? I could simply return the larger resultset and use managed code to filter out the rows I don't want; however, I would like to get to the bottom of this, especially if it's going to effect future queries.
Cheers,
Chris

Sep 13, 2000I am designing my first SQL database and need some insight on datatypes.
What datatype is equivalent to autonumber like in MS Access.
When I convert an auto number field to to SQL it comes as int with a length of 4, Does this mean it will only auto increment to 9999?
I need the field to increment forever.
Also what datatypes should be used for phone number with area code and
zip code.
Thanks

Nov 20, 2000Hi i'm using the FileSystemObject to loop through a file and read out all the data within it (it's an html page, so loads of tags and free text) and then put it in a field in a table. I am using the nText datatype but i don't think i use Full-Text Searching with this, is there any other i can use that produces the same result?

Apr 10, 2002Hello,
I'm 17 years old and I'm from Belgium, and I have to make a school project. I have to make a program in Visual Basic and my database is SQL Server 2000. I've already made my tables but I dont know excactly what all the datatypes in SQL Server are. They are a little bit different then Access datatypes and I dont know what to use, ntext, text, nvar, ... I can't find a list of the meaning of the datatypes on the net, maybe I'm searching with the wrong keywords(+"sql server" +datatypes in yahoo), but could please someone give me a link of a site where there is that kind of information?
thanks a lot :)

Aug 4, 2004I'm new to SQLServer and I'm creating some tables. In Oracle I always used varchar as this was the default and also recommended. The default in SQLServer seems to be char. Am I right in thinking that varchar is still best to use, as the field can then be of variable length rather than fixed?

Apr 1, 2007I have a SQL 2005 database that's created by a survey data collectionsystem. Users of this system are fairly non-technical and have littleto no conscious control over the datatypes. As a result, the data ismostly stored quite inefficiently as varchars. For example, there isdata that could be stored in a column of bits and it's stored as avarchar value of 0 or 1. (Yuck, I know.)I am building a reporting system using this raw data and have a newtable structure designed that is much more efficient (and better forreporting). Does anyone have any suggestions for getting this datainto my new structure? Specifically, how would you recommend checkingthat varchar field and determining it could be stored as a bit?

Jun 9, 2000Two datatype problems: (1) Datetime conversion (2) Foreign Currency format.
The first problem is that I am trying to convert source data from varchar to datetime. The source data is in CSV format and is displayed as follows - '1111999052349' to represent 1-Nov-1999 05:23:49. Have converted to a numeric value and then tried to convert to datetime but this just returns the following message 'Server: Msg 8115, Level 16, State 2, Line 3
Arithmetic overflow error converting expression to data type datetime.' However you can convert to a timestamp but the value returned is not meaningful (e.g. 0x0E0000013DFA4EE8).
Problem 2 concerns the French currency. The source data is in CSV format and is displayed as follows - '00000001,9700' to represent Fr1.97. Need to convert this to a numeric field or alternatively get SQL 7 to recognise it as a money field.
Any suggestions would be musch appreciated.
Many Thanks.

Exporting BIT Datatypes?
Jun 24, 2004Hi all. Im tryin to export (DTS) my some SQL server tables, many of which contain 'bit' datatypes. However, when DTS/SQL Serv. moves these bit datatypes out, it changes bit values to True/False values - which makes sense - however these are all going to plugin to web frontends where the SQL specifies condtions like: "if column1 = 0 then" etc..
Is there anyway to get SQL server to export bit datatypes as just numeric values of 0/1?
Converting Datatypes, Not Sure If This Is Right?
Sep 28, 2007New to developing. We are working on a project using asp.net and c# where data is pulled out of an sql database via multiple tables and displayed via a details view. The user can then update the information and submit it back to the database.
The problem we are encountering is:
Within the database there are multiple tables joined by a FK for example there is a Service Group ID column with the Records main table linked to the Service Group table which holds an ID column and a Service Group column so ID1 = Service Group A. Any records within the main table which has an ID of 1, is shows as Service Group A in the details view.
What we wold like to do is when a user updates the Service Group via a drop down, the ID goes into the main table rather than the Service Group name so if they select Service Group B, an ID of 2 goes into the Records main table. We aren't sure how to go about doing the conversion of Service Group B to an ID 2? We have been looking at converting datatypes but don't think it is right for what we are trying to do,
Any suggestions would be gratefully recieved Apologies if this is in the wrong forum.
