Hello,
Could anybody tell me if it's possible to named the result of this query?
SELECT User_Id, Name, Surname, Age, Nationality
FROM [Basic Data] FOR XML PATH, TYPE, elements, root('AllPrimaryData')
The result of this query is an XML Document in a column without a name and I'm trying to name it but I can't.
Could anybody help me with that?
Thanks a lot.
Hi everyone In my SqlServer Management Studio Express, on start up it shows the server type option, but greyed.So that value is fixed to database engine. ( I'm trying to work on an SqlServer Compact Edition database through the SSMStudiothat's why I'm trying to get this to change.)Besides, after I connect i go to the Object Explorer, expand the server node, and go to Replication.When i expand replication, i get the "Local Subscription" option, but nothng for Publication.( I want to work on Merge Replication, that's why I desparately need Publication to work)Am i missing something here? I did not install SqlServer separately, I only have what comes bundled with the Visual Studio 2005 Setup.

I need to expand resursion level for resursive CTE expression within CREATE FUNCTION statement for inline table function to a value greater than default. It turns out that OPTION clause for MAXRECURSION hint perfectly works if I use it outside CREATE FUNCTION (as well as CREATE VIEW for non-parametrized queries), but it does not within CREATE FUNCTION statement - I'm getting error:

So I started a new job recently and have noticed a few strange configurations. Typically I would never mess with min memory per query option and index create memory option configuration because i just haven't seen any need to. My typical thought is that if it isn't broke... They have been modified on every single server in my environment.
From Books Online:
• This option is an advanced option and should be changed only by an experienced database administrator or certified SQL Server technician.
• The index create memory option is self-configuring and usually works without requiring adjustment. However, if you experience difficulties creating indexes, consider increasing the value of this option from its run value.
I have a quite big SQL query which would be nice to be used using UNION betweern two Select and Where clauses. I noticed that if both Select clauses have Where part between UNION other is ignored. How can I prevent this?
I found a article in StackOverflow saying that if UNION has e.g. two Selects with Where conditions other one will not work. [URL] ....
I have installed SQL Server 2014 and I tried to use tricks mentioned in StackOverflow's article but couldn't succeeded.
Any example how to write two Selects with own Where clauses and those Selects are joined with UNION?
Hi, can anyone shed some light on this issue?SELECT Status from lupStatuswith a normal query it returns the correct recordcountSELECT Status from lupStatus GROUP BY Statusbut with a GROUP By clause or DISTINCT clause it return the recordcount= -1
View 3 Replies View RelatedI am working with a vendor on upgrading their application from SQL2K to SQL2K5 and am running into the following.
When on SQL Server 2000 the following statement ran without issue:
UPDATE dbo.Track_ID
SET dbo.Track_ID.Processed = 4 --Regular 1 leg call thats been completed
WHERE Processed = 0 AND LegNum = 1
AND TrackID IN
(
SELECT TrackID
FROM dbo.Track_ID
GROUP BY TrackID
HAVING MAX(LegNum) = 1 AND
TrackID + 'x1' IN
(
SELECT
dbo.Track_ID.TrackID + 'x' + CONVERT(NVARCHAR(2), COUNT(dbo.Track_ID.TrackID))
FROM dbo.Track_ID INNER JOIN dbo.transactions
ON dbo.Track_ID.SM_ID = dbo.transactions.sm_session_id
GROUP BY dbo.Track_ID.TrackID
)
)
Once moved to SQL Server 2005 the statement would not return and showed SOS_SCHEDULER_YIELD to be the waittype when executed. This machine is SP1 and needs to be upgraded to SP2, something that is not going to happen near time.
I changed the SQL to the following, SQL Server now runs it in under a second, but now the app is not functioning correctly. Are the above and the following semantically the same?
UPDATE dbo.Track_ID
SET dbo.Track_ID.Processed = 4 --Regular 1 leg call thats been completed
WHERE Processed = 0 AND LegNum = 1
AND TrackID IN
(
SELECT TrackID
FROM dbo.Track_ID
WHERE TrackID + 'x1' IN
(
SELECT dbo.Track_ID.TrackID + 'x' + CONVERT(NVARCHAR(2), COUNT(dbo.Track_ID.TrackID))
FROM dbo.Track_ID INNER JOIN dbo.transactions
ON dbo.Track_ID.SM_ID = dbo.transactions.sm_session_id
GROUP BY dbo.Track_ID.TrackID
)
GROUP BY TrackID
HAVING MAX(LegNum) = 1
)
2 examples:
1) Rows ordered using textual id rather than numeric id
Code Snippet
select
cast(v.id as nvarchar(2)) id
from
(
select 1 id
union select 2 id
union select 11 id
) v
order by
v.id
Result set is ordered as: 1, 11, 2
I expect: 1,2,11
if renamed or removed alias for "cast(v.id as nvarchar(2))" expression then all works fine.
2) SQL server reject query below with next message
Server: Msg 169, Level 15, State 3, Line 16
A column has been specified more than once in the order by list. Columns in the order by list must be unique.
Code Snippet
select
cast(v.id as nvarchar(2)) id
from
(
select 1 id
union select 2 id
union select 11 id
) v
cross join (
select 1 id
union select 2 id
union select 11 id
) u
order by
v.id
,u.id
Again, if renamed or removed alias for "cast(v.id as nvarchar(2))" expression then all works fine.
It reproducible on

In both cases database collation is SQL_Latin1_General_CP1251_CS_AS
If I check quieries above on database with SQL_Latin1_General_CP1_CI_AS collation then it works fine again.
Could someone clarify - is it bug or expected behaviour?

Happy Friday!
A while since I have posted a question, and this one is probably real easy.
I am trying to store numeric values from a php form in MSSQL 2000 database. However, the columns are set to float and if the value is 1.00, when entered into the table it is saved as 1
If I change the column type to money, the query fails, with an error message of conversion of datatype varchar to datatype money statement terminated.
anybody know what I need to do? do I need to do something in my query to specify that this is NOT varchar data?
I like to define my procedure parameter type to match a referenced table colum type,
similar to PL/SQL "table.column%type" notation.
That way, when the table column is changes, I would not have to change my stored proc.
Any suggestion?
Hi,

we need to store values as is

Implement time interval type in the form of a user defined type in SS2k8r2? Specifically an interval type described in the book Temporal Data and the Relational Model by C. J. Date at all. As an example, an interval is below:
1/4/2006:1/10/2006
which would mean the time period from 1/4 to 1/10.
I am trying to use the Bulk Insert Task to load from a csv file. My final column is a bit that is nullable. My file is an ID column that is int, a date column that is mm/dd/yyy, then 20 columns that are real, and a final column that is bit. I've tried various combinations of codepage and datafiletype on my task component. When I have RAW with Char, I get the error included below. If I change to RAW/Native or codepage 1252, I don't have an issue with the bit; however, errors start generating on the ID and date columns.
I have tried various data type settings on my flat file connection, too. I have tried DT_BOOL and the integer datatypes. Nothing seems to work.
I hope someone can help me work through this.
Thanks in advance,

Hi all,
I am developing ASP.NET 1.1 application using VB.NET & SQL Server, on my machine I am using SQL Server 2000, and everything is working just fine.
The problem appears when I uploaded the site to the Host, they are using SQL Server 2005, is there any reason for this, I am using casting in the code, and I am sure there is something wrong with the hosting settings.
Any suggestions.
Best Regards

Hello Friends
How are you?? Friends i am getting problem in SQL Server 2005. I am deployng web application on production server as well as Databse also. In production server i inserted new field in all tables which is rowguid and its type is uniqueidentifier. The default binding for this field is newsequentialid(). In some pages it works ok but in some places it generates error like 'Conversion from type 'DBNull' to type 'String' is not valid'. Can anybody help me to solve this problem. Its urgent so plz reply me as soon as possible. I'll be very thankfull to you. Thanks in Advance.
Regards,
I have extensively revied both of the design methodologies and I cannot come up with a single clear reason to use one over the other!
Type - Attributes is where you have a table holding the type categories, type, a table holding the type attributes expected and then a table holding the type attribute value:
tbAutombbileCategories
CategoryID | Category
-------------------------------
1 | Car
2 | Truck
3 | Motorcycle
tbAutomobileAttributes
AttributeID | fkCategoryID | Attribute
-------------------------------------------
1 | 1 (car) | Doors
2 | 2 (truck) | Cab
3 | 2 (truck) | Capacity
tbAutomobile
VIN | Category | Make | Model
-------------------------------------
1 | 1 | Honda | Accord
2 | 2 | Ford | F150
tbAutomobileAttributeValues
fkVIN | fkAttributeID | Value
---------------------------------
1 | 1 | 2
2 | 1 | 0
2 | 2 | 1000
Now the above sure is flexible in the sence that a type of automobile can be added without affecting the database schema, but was if some attributes do not take a numeric value? How do you handle computations on attributes specific attributes? Why would I use this structure as opposed to the super type - sub type as shown below?
tbCategories
CategoryID | Category
--------------------------
1 | Cars
2 | Trucks
tbAutomobile (Super Type)
VIN | fkCategoryID | Make | Model
-------------------------------------
1 | 1 |Honda | Accord
tbCars
fkVIN | Doors |
-----------------
1 | 2
tbTrucks
fkVIN | Cab | Capacity
---------------------------
2 | 0 | 1000
Now, adding new sub types probably isn't very flexible but, now you can specify data types for each attribute instead of using sql_variant, which by the documentation cannot be used in aggregate functions and may render poor result when used with ADO.
Regardless of the method used, alot of back end coding is required for computations, what table to send the attributes, etc...
Can anyone please help me clarify. What method is best and why. So far I am leaning for option 2. More work but seems to be more flexible in the sence of customization of each datatype.
E.G., what if you wanted to specify attributes about the cap that can be supplied to trucks?
tbTrucks
fkVIN | Cab | Capacity | fkCapID
--------------------------------------
2 | Y | 1000 | 1
tbCaps
CapID | Vendor | Price | et....
Any thoughts at all? I thought this would have been a pretty damn hot topic!

I'm trying to use the SSIS Execute SQL Task to pull XML from a SQL 2005 database table. The SQL is of the following form:
SELECT
(
SELECT
MT.MessageId 'MessageId',
MT.MessageType 'MessageType',
FROM MessageTable MT
ORDER BY MT.messageid desc
FOR XML PATH('MessageStatus'), TYPE
)
FOR XML PATH('Report'), TYPE
For some reason I can only get this query to work if I use an ADO.NET connection type. If I try to use something like the OLEDB connection I get the following error:
<ROOT><?MSSQLError HResult="0x80004005" Source="Microsoft XML Extensions to SQL Server" Description="No description provided"?></ROOT>
Can anyone tell me why the SELECT ... FOR XML PATH... seems only to work with ADO.NET connections?
Thanks

How i can fetch the lotus notes data in my asp.net pages.
Hello --
I am having a UDT problem. When I run the Create Type command. I receive the "could not find type" error. I have seen other posts on here related to the default namespace in VB.NET. When I add the namespace I receive "Incorrect syntax near '.'." What is the format of the EXTERNAL NAME parameter. Thanks for any help. Code below...
Incorrect Syntax Error:
DROP ASSEMBLY CadSqlUdtsCREATE ASSEMBLY CadSqlUdtsAUTHORIZATION [dbo]FROM 'E:CAD.NETCADUDTsReleaseCadSqlUdts.dll'WITH PERMISSION_SET = SAFEGOCREATE TYPE dbo.ReportingAreaUDTEXTERNAL NAME CadSqlUdts.[CadSqlUdts.CadSqlUdts].ReportingAreaUDT;GO
Could Not Find Type Error:
DROP ASSEMBLY CadSqlUdtsCREATE ASSEMBLY CadSqlUdtsAUTHORIZATION [dbo]FROM 'E:CAD.NETCADUDTsReleaseCadSqlUdts.dll'WITH PERMISSION_SET = SAFEGOCREATE TYPE dbo.ReportingAreaUDTEXTERNAL NAME CadSqlUdts.ReportingAreaUDT;GO
What's up??
Hi,
What is HAVING clause equivalent in the following oracle query, without the combination of "GROUP BY" clause ?
eg :
SELECT SUM(col1) from test HAVING col2 < 5
SELECT SUM(col1) from test WHERE x=y AND HAVING col2 < 5
I want the equivalent query in MSSQLServer for the above Oracle query.
Also, does the aggregate function in Select column(here the SUM(col1)) affect in anyway the presence of HAVING clause?.
Thanks,
Gopi.

hi..
i have basic question like
what is differance between conditions put in ON clause and in WHERE clause in JOINS????
see conditions that shown in brown color
select d1.SourceID, d1.PID, d1.SummaryID, d1.EffectiveDate,
d1.Audit, d1.ExpirationDate, d1.Indicator
from[DB1].[dbo].[Implicit] d1 inner join [DB2].[dbo].[Implicit] d2
on d1.SummaryID=d2.SummaryID
AND d1.ListType = d2.ListType
AND (d1.EffectiveDate <= d2.ExpirationDate or d2.ExpirationDate is null)
AND (d1.ExpirationDate >= d2.EffectiveDate or d1.ExpirationDate is null)
whered1.ImplicitID >= d2.ImplicitID AND
(d1.SourceID<>d2.SourceID
OR (d1.SourceID IS NULL AND d2.SourceID IS NOT NULL)
OR (d1.SourceID IS NOT NULL AND d2.SourceID IS NULL)
)
select d1.SourceID, d1.PID, d1.SummaryID, d1.EffectiveDate,
d1.Audit, d1.ExpirationDate, d1.Indicator
from[DB1].[dbo].[Implicit] d1 inner join [DB2].[dbo].[Implicit] d2
on d1.SummaryID=d2.SummaryID
AND d1.ImplicitID = d1.ImplicitIDAND d1.ListType = d2.ListType
AND (d1.EffectiveDate <= d2.ExpirationDate or d2.ExpirationDate is null)
AND (d1.ExpirationDate >= d2.EffectiveDate or d1.ExpirationDate is null)
whered1.ImplicitID >= d2.ImplicitID AND
(d1.SourceID<>d2.SourceID
OR (d1.SourceID IS NULL AND d2.SourceID IS NOT NULL)
OR (d1.SourceID IS NOT NULL AND d2.SourceID IS NULL)
)
another thing...
if we put AND d1.ImplicitID = d1.ImplicitID condition in second query then shall we remove
d1.ImplicitID >= d2.ImplicitID from WHERE clause????
Hi everyone,
I saw some queries where SQL inner join clause and the where clause is used at the same time. I knew that "on" is used instead of the "where" clause. Would anyone please exaplin me why both "where" and "on" clause is used in some sql Select queries ?
Thanks

I get the following message in the vs2005 querybuilder when i do a preview:
***********************************
SQL Execution Error.
Executed SQL statement: SELECT Schoolindex, Variant, VVSchool, [index], indincl, VVRuimtes, School FROM School WHERE (Schoolindex = @PARAM1)
Error Source: SQL Server Compact Edition ADO.NET Data Provider
Error Message: @PARAM1 : Unable to cast object of type 'System.Data.SqlTypes.SqlInt32 to type System.IConvertable'.
****************************************
The same querypreview works fine without the parameter:
SELECT Schoolindex, Variant, VVSchool, [index], indincl, VVRuimtes, School FROM School WHERE (Schoolindex = 186)
Can anybody tell me why this is?
And tell me a way to get the tableadapter working?

Hi all,I have a table called PTRANS with few columns (see create script below).I have created a view on top that this table VwTransaction (See below)I can now run this query without a problem:select * from dbo.VwTransactionwhereAssetNumber = '101001' andTransactionDate <= '7/1/2003'But when I create an index on the PTRANS table using the command below:CREATE INDEX IDX_PTRANS_CHL# ON PTRANS(CHL#)The same query that ran fine before, fails with the error:Server: Msg 242, Level 16, State 3, Line 1The conversion of a char data type to a datetime data type resulted inan out-of-range datetime value.I can run the same query by commeting out the AssetNumber clause and itworks fine. I can also run the query commenting out the TransactionDatecolumn and it works fine. But when I have both the conditions in theWHERE clause, it gives me this error. Dropping the index solves theproblem.Can anyone tell me why an index would cause a query to fail?Thanks a lot in advance,AmirCREATE TABLE [PTRANS] ([CHL#] [varchar] (100) COLLATE SQL_Latin1_General_CP1_CI_AS NULL ,[CHCENT] [numeric](2, 0) NOT NULL ,[CHYYMM] [numeric](4, 0) NOT NULL ,[CHDAY] [numeric](2, 0) NOT NULL ,[CHTC] [char] (2) COLLATE SQL_Latin1_General_CP1_CI_AS NOT NULL) ON [PRIMARY]GOCREATE VIEW dbo.vwTransactionsASSELECT CONVERT(datetime, dbo.udf_AddDashes(REPLICATE('0', 2 -LEN(CHCENT)) + CONVERT(varchar, CHCENT) + REPLICATE('0', 4 -LEN(CHYYMM))+ CONVERT(varchar, CHYYMM) + REPLICATE('0', 2 -LEN(CHDAY)) + CONVERT(varchar, CHDAY)), 20) AS TransactionDate,CHL# AS AssetNumber,CHTC AS TransactionCodeFROM dbo.PTRANSWHERE (CHCENT <> 0) AND (CHTC <> 'RA')*** Sent via Developersdex http://www.developersdex.com ***Don't just participate in USENET...get rewarded for it!
View 1 Replies View RelatedI have a ntext column which stores rows of xml data. Ive decided that the best way to query the xml data is to Convert the ntext data into xml data type and use Sql Server 2005 builtin Xml Query tools to perform FLWOR expressions. The problem Im having is getting the ntext data Converted to xml.When I try to convert the ntext text, I of course get an error that local variables of ntext type are invalid.Any suggestions on a way I might accomplish this?Thanks, -lance
View 1 Replies View RelatedHi
Is it possibly in SqlDataSource's SelectCommad to convert a text-type value to a date-type value (11/1/2008 (text) -> 11/1/2008 (date) ) , so that order by can be used. Or is the other ways to use order by correctly with text-type (date)values
Thanks.
