Converting From Ora To SQL Server
Dec 29, 2005
I'm new to SQL server.
I've been working with oracle and now need to convert this sentence to SQL Server but I get this error:
Server: Msg 170, Level 15, State 1, Line 1
Line 1: Incorrect syntax near 'A'.
Server: Msg 156, Level 15, State 1, Line 6
Incorrect syntax near the keyword 'where'.m_proceso;
My sentence is:
/*****************
update data_grup A
set
new_grup_code =( select cod_grup_2
from data_grup_new B
where A.cod_grup = B.cod_grup )
where zone = '001' ;
/*****************
Can anyone help me to convert this to SQL server, I don't know why I get this error.
Thanks.

So where I work is thinking about one day moving to SQL server. Right now they have indexed files that aren't normalized with repeating fields in them and lots of repeat data and blank space (so a customer number in one file may be stored literally in 10 other files that are easily realted). In the intrest of saving time and money I think that they will not normalize, index, or anything to any of these files. From what I hear it will be a straight field by field creation for the most part and preserving the primary keys.
My question: I keep thinking this is going to be massive hit on performance and maintaince. How much would converting in such a manner hurt the performance of their database and how much could it potentially add to maintaince?

Hi Folks!
I have the following sql script I wrote using Explicit Option to convert data from SQL Server tables into a single XML file. I am aware of the tedious nature of the select statements, but this seems to the only option I have to depict parent-child nature of the data in XML format and also to schedule it as a job to run via SQL Server Agent.
My problem is that as I run this using the following command, I get "There is insufficient system memory to run this query" error.
I am using the following commnd:
exec master..xp_cmdshell 'bcp "EXEC swr_cv2..sproc_BuildXMLTree" queryout "C: est.xml" -U -P -c -r -t'
Is there any way I can tune my query to fix that error?
Thanks so much for your help!

I'm currently using Management Studio 2008 R2 and struggling as I am very raw to SQL full stop eg a complete newbie to it.
WHERE (((dbo_ED_ATTENDANCE.AttendDateTime)>=Date()-IIf(Weekday(Date(),2)<2,4,2) And (dbo_ED_ATTENDANCE.AttendDateTime)<=Date()-1)
The above criteria is cut from an existing Access query which I am trying to replicate in SQL Management Studio 2008 R2.

Hope this makes sense.
I am trying to convert an Access based blog app to SQL Server but I'm having some trouble with some SQL.
The sql is as follows:
SELECT *, (SELECT COUNT(*) FROM tblComment WHERE tblComment.blogID = tblBlog.BlogID AND tblComment.commentInclude <> 0) AS TOTAL_LINKS
FROM joinBlog
WHERE BlogIncluded <> 0
ORDER BY BlogID DESC
The access version returns blog entries & the number of comments posted to each entry.
joinBlog is an Access query:
SELECT tblBlog.BlogID, tblBlog.CatID AS tblBlog_CatID, tblBlog.BlogHeadline, tblBlog.BlogHTML, tblBlog.BlogDate, tblBlog.BlogIncluded, tblCategory.catID AS tblCategory_catID, tblCategory.catName
FROM tblCategory RIGHT JOIN tblBlog ON tblCategory.catID = tblBlog.CatID;
I assume I need to make a view out of the Access query, I have done this & that appears to work.
The problem I have is when I try the 1st sql that is in my page with sql server I get the following error:
The column prefix 'tblBlog' does not match with a table name or alias name used in the query.
I can make the following change which returns data but does not attach the blog comment counts to the proper blog entry, instead it returns the total comments in the query:
SELECT *, (SELECT COUNT(*) FROM tblComment,tblBlog WHERE tblComment.blogID = tblBlog.BlogID AND tblComment.commentInclude <> 0) AS TOTAL_LINKS
FROM joinBlog
WHERE BlogIncluded <> 0
ORDER BY BlogID DESC
Can anyone tell me how to convert this for SQL Server? This is my 1st access to sql server attempt.
Thanks.

I need to switch from MS Access to SQL Server for my database. To set
up a development environment I downloaded the free Microsoft SQL Server
Express (February CTP version). I installed the required .NET Framework
v2, and then SQLExpress. The install was done using all the defaults,
and was done successfully. I also downloaded and installed the SQL
Express Manager Tool.
The SQL Server was installed on the same machine as my VS.NET
development environment. The SQL Server process is now running, and I
can connect to the server using the SQL Express Manager Tool. This
allows me to view and query the sample databases, but not much else.
To convert my Access .MDB database to SQL Server, I am trying to use
the MS Access Upsizing Wizard. The version of Access I am using is
Access 2002 on a Windows XP-Professional system. The problem is that
Access cannot get a connection to the SQL Server. I tried using the
default server name "(local)" and "Use Trusted Connection", but I
receive the following error:
Connection failed:
SQLState: '01000'
SQL Server Error: 2
[Microsoft][ODBC SQL Server Driver[]Shared Memory]ConnectionOpen (Connect()).
Connection failed:
SQLState: '08001'
SQL Server Error: 17
[Microsoft][ODBC SQL Server Driver[]Shared Memory]SQL Server does not exist or access denied.
Curiously, I get this exact same error message even if the SQL service
is stopped. So I'm pretty sure the problem is that it is not finding
the SQL server, and not a security issue.
In order to connect to the SQL server using the SQL Server Manager
Tool, you have to provide the actual instance name for the server
"COMPNAMESQLExpress". So I tried using this server name in the Access
Upsizing Wizard, but this returns the same error message as above
except the first SQL Server Error is 53. I also tried using a Login ID
and password (using the Windows administrator ID and password, and also
the "sa" ID and password) to no avail.
I am at wits end, and can't figure out why Access can't find the SQL Server. Any ideas would be appreciated.
Thanks.

Hi There, I'm new to the .Net environment, and I am currently trying to convert an xml document and its appropriate schema, to a dataset then with this Dataset I would like to load it into the database. This XML file is generated from the Access 2000 format. Then sent over the internet where it is received by an HttpFileCollection object, then the schema and xml file are loaded into a dataset. I have created a new SQL database in which I imported the table required from Access, so in theory the table that the xml is generated from should be the same as the table that the xml is destined for. I am getting the data loaded into the dataset however, when I try to execute the data adapter update command
oda.Update(myDS, "MSGLOBAL") it is throwing an Exception, in this exception the message is telling me that there is a problem near the key word 'on'. Now I have added a watch window to monitor the sql statements, now the oda has an insert statement generated from a query builder, however this same query builder will not create either an update or delete command. I hope this is a good enough explanation to get a few answers, or a possible example, it seems to be a topic that is quite difficult to research. Thank you, and if you require more info please indicate this. Damon Http://www.ezywiz.biz

OK, I have some SQL Server 2000 databases that I want to convert to 2005. My question: how do I do that?
I tried importing the data, but it only picked up 3 tables out of 7 user tables in one of my SS2K databases. Plus, it did not pick up any stored procedures or any other kind of objects.
So I tried restoring from a backup, but predictably it could not do that because the original backup was on a different server.
I also tried the upgrade advisor utility that comes with SS2K5, but it could not seem to connect to my SS2K server -- it said it could not find any SQL Server objects on the server, even though I am connected using Enterprise Manager and have been using this server for a long time. Is it looking for 2005 databases? That wouldn't make a lot of sense.
Anyway, I am stumped... can anyone provide help on this?
Thanks!

I'm trying to convert a 6.5 compatible db from SQL Server 2000 to SQL Server 2005. The issue I'm encountering is that:
1. I cannot simply convert the 6.5 compatible db to SQL Server 2005. I tried restoring from a backup - no success.
2. I tried creating the structure in SQL Server 2005 and then importing the data from SQL Server 2000. Problem is - after importing the data, I then tried creating the primary key and indexes - get a time-out error (which I never got with SQL Server 2000.) I also tried creating the primary key and indexes in SQL Server 2005 FIRST before importing - got errors when trying to import and import failed.
I know this sounds like a data problem but I have no problems working with this 3 gig database in SQL Server 2000.
Can anyone please help? This is a pretty serious problem I need to overcome with the SQL Server 2005 conversion.

I am trying to upsize a database to SQL server (on which I am a novice). InAccess as part of a much more complex query I had the following (from sqlview)SELECTIIf(InStr([ItemName],"*")>0,Left([ItemName],InStr([ItemName],"*")-1),[ItemName]) AS ShortName FROM corp_infoWhich gives a return value for the whole of ItemName if there is no star init, or the portion up to the star if there is a starI am having a nightmare trying to get an equivalent in SQL server. I'veworked out that Instr is charindex in sql and can adjust for that, but can'twork out how to get a conditional select statement working.It may well be obvious, but any help much appreciated.

Hello,
Finally making the move to ASP.NET! I've been advised that to begin with it is probably best to start using SQL Server 2005 with ASP.NET. All my sites are currently using MySQL. Can anyone advise a way for me to import all the data from a MySQL database to a SQL Server 2005 database. Apologies if this isn't directly related to ASP.NET but any help would be greatly appreciated.

I'm trying to go deeper into SQL Server's XML support. When looking at a recent forum post, I got curious to see if I could achieve the same result with XPath and FLOWR. Here's the data I'm working with:
create table #data (myXMLData xml)
insert into #data(myXMLData) values (
'<?xml version="1.0" encoding="utf-8"?>
<order>
<Product Index="e1e2c499-f9...etc...." ProductID="12" >
<Attribute Name="Paper...etc..." />
[Code] ....
Here's the working XPath query and results:
select data.mynodes.value('@Name', 'varchar(50)') Name
from #data
cross apply myXMLData.nodes('/order/Product/Drops/Drop[@Number="1"]/Area') data(mynodes)
Results:
Name
43001PBOX
[Code] .....
Here's my first attempt at a FLWOR expression. Note that doesn't produce the same results.
select myXmlData.query('
for $drop in /order/Product/Drops/Drop
for $Name in $drop/Area/@Name
where $drop/@Number=1
return data($Name)
')
from #data
Results:
43001PBOX 43001R001 43001R002 43023PBOX 43023R001 43023R002 43031PBOX 43031R001
How to build a FLOWR-based query that produces the same result as the pure XPath one?

I'm leaning toward detaching the data on my 2000 box, duplicating it, copying it to my new 2005 machine, and attaching it. Is it possible that it could be that simple? If not, how is it done?

difference between
SELECT ROUND ('6.465',2) --- result 6.46
and
SELECT ROUND (6.465,2) --- result 6.47
with
It's because you're relying on an implicit conversion from a string to a decimal data type which SQL server will do to 2 decimal places by default...
Alright:
SELECT ROUND (CONVERT(DECIMAL(3,2),'6.465'),2) --- result 6.47 Now please explain this:
SELECT ROUND('0.285',2) -- 0.28
SELECT ROUND(0.285,2) -- 0.29
SELECT ROUND (CONVERT(DECIMAL(3,2),'0.285'),2) --- result 0.29 The string value does not seem to be converted to decimal with 2 decimal places.
MS is on the safe side with mentioning the last digit is always an estimate But because the result of the estimate is always the same, I would like to know:
* how is a string value exactly implicitly converted?
* how exactly does the estimation work, that in case of doubt rounds a value up or off?

I have a lot of rows of hours, set up like this: 0745, 0800, 2200, 1145 and so on (varchar(5), for some reason).
These are converted into a smalldatetime like this:
CONVERT(smalldatetime, STUFF(timestarted, 3, 0, ':')) [this would give output like this - 1900-01-01 11:45:00]
This code has been in place for years...and we stick the date on later from another column.
But recently, it's started to fail for some rows, with "The conversion of a varchar data type to a smalldatetime data type resulted in an out-of-range value".
My assumption is that new data being added in is junk. If I query for these values and just list them (rather than adding a column to convert them also) that's fine, of course. I've checked all the stuffed (but not yet converted - so 11:45 rather than 1145) output to see if it ISDATE(), and it is. There are no times with hours > 23 or minutes greater than 59 either.
If I add the CONVERT in, we see the error message. But here's the oddity, if I place all of the rows into a holding table, and retry the conversion, there is no error. It's this last bit that is puzzling me. Plus I can't see any errors in the hours data that would cause a conversion problem.
I've put the whole of this into a cursor to try to trap the error rows too, but all processes fine. Why would it fail if NOT in a cursor?
