Now, the developement in SqlServer Clr is obviously different from the develop in normal programs. there are many limitation in Clr develop, and it take many work to use dll alread exsits in Clr develop.
I do know that some limitation is reasonable, BUT much more limitation should be removed.
For example, now in order to use enum that exists in old dll in sqlServer, we have to create a new project and write many similar class to wrap the old enums, it's very troublesomely and slow!
so pls make the develop model consistent as possible.

So I have 2 options :

Is it possible to built a query like this,I mean assigning data as column?
Any help will be greatly appreciated.

Hi all.
we have a department that has an access database with a bunch of queries in it. They want us to convert it to sql server. One of the queries is a cross-tab query. Is there an easy way to create this in sql? the column headings are the value of column from a table. This could change each month that they run it. How do I make the column heading a variable? I'm guessing a stored procedure would be best. Does anyone have any suggestions?
Thanks so much.

Hi - I have what I think is a "simple problem".We currently have a database table that stores ItemProperties byItemID, PropertyID and Value. (The PropertyID references another tablefor property names and types.)This ItemProperties table is indexed and provides a flexible way ofstoring our item metadata. However, I would now like to returnrecordsets to the application layer that list these properties incolumn fashion, grouped by ItemIDI have seen that most cross-tab queries examples assume numerical dataand are based around using SUM and the GROUP BY phrase. But our datais a mixture of string and numbers (of various formats) and so GROUPBY is not an obvious solution. I have tried using CASE in the selectlist but this returns one row for each property with one column havingthe correct value, and all the other colums are NULL. I cannot thinkof how to combine these into one full record!!I could achieve the desired resultset by using a SELECT sub-statementfor every column, but I was hoping there was a more efficient method.Can anyone offer advice on this? It would be most appreciated.Best,Bill

Is there any simple cross tab query template, which can used by general user?
I need it so that I can provide it to our Power users, so that they can use it themselves, instead of coming back to the IT Department.
(something similar like the one found in the Access)

How do you write a SQL SELECT statement for a cross-database query in ASP.NET (ADO.NET). I understand the server.database.owner.table structure, but the command runs under a connection. How do I run a query under two connections?

I am trying run a select and insert in query analyzer on another database across servers. They are both running win 2003 one with SQL2003 Enterprise(the server name of this one is svr-sql-ams6401 and I am running this query while connected to this database in Analyzer) and one with SQL2k Standard(svr-amed-sql). Below is the query with results:
insert into s_msfreq (freqgroup, freqcode, descrip)
select freqgroup, freqcode, descrip
from [svr-amed-sql].ams.dbo.s_msfreq
where freqgroup = 'PRSERC'
I get
Server: Msg 7399, Level 16, State 1, Line 1
OLE DB provider 'SQLOLEDB' reported an error.
[OLE/DB provider returned message: Unspecified error]
[OLE/DB provider returned message: The stored procedure required to complete this operation could not be found on the server (they were supplied with the ODBC setup disk for the SQL Server driver). Please contact your system administrator.]
OLE DB error trace [OLE/DB Provider 'SQLOLEDB' IDBSchemaRowset::GetRowset returned 0x80004005: ].
I am pretty sure these servers are linked.... but how do I tell and how do I link the two if they are not? Or, is this not the problem?
Thanks guys!!

Hi all,
My support team inform me that my servers have been updated and rebooted on monday. Now I need to run some cross db queries today and I dont seem to be able to connect anymore. I am getting the (dreaded apparant but not surprisingly) Msg 17, Level 16, State 1, Line 1
[DBNETLIB][ConnectionOpen (Connect()).]SQL Server does not exist or access denied.
Now first thing I did was try to drop both linked servers and add again. I am thinking that the particular server has a dynamic ip which I have determined. Ive noticed a work around on MSFT but it say about using a connection string with IP.
Can anyone help me work this out? id appreciate it.

I have three tables:tblBook has the fields bookID, bookRangeID, bookSubjectID, bookCodetblBookRange has the fields bookRangeID, bookRangeDescriptiontblBookSubject has the fields bookSubjectID, bookSubjectDescriptionso some typical data in tblBook might be:1, 1, 1, B1HBSCI2, 1, 2, B2HBFRE13, 1, 3, B3HBGER4, 2, 1, B4PBSCI5, 2, 2, B5PBFRE6, 2, 3, B6PBGER7, 3, 1, B7CDSCI8, 3, 2, B8CDFRE9, 3, 3, B9CDGER110, 3, 3, B10CDGER211, 1, 2, B11HBFRE2tblBookRange would be:1, HardBack2, PaperBack3, CD RomtblBookSubject would be:1, Science2, French3, GermanI'd like to create a query which will return me the subjects along thetop, the book range down the side, and the bookcodes in the cells, abit like this:BookRange , Science, French, GermanHardBack , B1HBSCI, B2HBFRE1 B11HBFRE2, B3HBGERPaperBack , B4PBSCI, B5PBFRE, B6PBGERCD Rom , B7CDSCI, B8CDFRE, B9CDGER1 B10CDGER2Does that make any sense? So basically I'd like to get some kind ofdynamic SQL working which will do this kind of thing. I don't want tohard code the subjects in or the book ranges. I get the feeling thatdynamic SQL is the way forward with this and possibly using a cursor ortwo too, but it got quite nasty and convoluted when I tried variousattempts to get it working. (one of the ways I tried included workingout each result in a dynamic script, but it ran out of characters asthere were too many "subjects".)If anyone has any nice but quite dynamic solutions, I'd be delighted tohear.(and I know some of you have already told me you don't like tablesbeginnig with tbl, but I'm not hear for a lecture on namingconventions, I'm hear to learn and share ideas :o) )

I dontknow how to generate this query.Can anybody give me a solution for this to be used in Sqlserver 2000 aswell as Sqlserver 2005.Thanks in advance

I have a table with results from several inspection tests. The Pass/Fail parameter in the cross-tab output would be Pass if all tests for that serial number are Pass, and Fail if any of the results for that serial number are Fail.
How would I create a cross-tab query in SQL Server?
Table for input to cross-tab query: [Inspection Data]
SerialNumber ParamName Result Pass/Fail
001 Test1 3.43 Pass
001 Test2 3.27 Pass
001 Test3 2.97 Pass
002 Test1 2.88 Pass

002 Test3 4.22 Fail
003 Test1 3.11 Pass
003 Test2 2.91 Pass
003 Test3 3.28 Pass
Cross-tab Query Output:
Test1 Test2 Test3 Pass/Fail
001 3.43 3.27 2.97 Pass
002 2.88 3.01 4.22 Fail
003 3.11 2.91 3.28 Pass

I have the following tables:members--------------member_idmember_tpc_id ( = tpc.tpc_id)tpc------tpc_idcourse------------course_idtpc_assignment---------------------------tpc_assignment_idcourse_idenrollment-------------------member_idcourse_idenrollment_status Now I want to select all members where member_tpc_id>0 and get the enrollment_status of each member in each course where course_id IN (Select course_id From tpc_assignment)Now what i did was get all the members and then all the courses and did a cross join between them. There are about 1900 members and 80 courses and when I do a cross join I get 1900*80 rows (152000) and the status of each member for all the 80 courses. If not enrolled it returns Not Enrolled (i have a UDF which takes a member_id and a course_id and returns the status). The BIG problem is that its taking about 6-8 mins to run the query and as a result its timing out on the aspx page. Can someone please tell me how I can do what i am trying to do without using the cross join because I suspect its the culprit here. The query I came up with is Select
*, dbo.returnStatus(temp1.user_id, temp2.course_id) As Status,
(Select tpc_title From tpc Where tpc_id = temp1.member_tpc_id) As Tpc_Title
From
(Select member_id As user_id, member_name, member_tpc_id
From members Where member_tpc_id> 0 And organization_id = '1'
)temp1
cross join
(Select course_id As course_id, course_title As course_title
From course Where course_id IN
(Select course_id From tpc_assignment Where tpc_requirement_id IN
(Select tpc_requirement_id From tpc_requirement) And course_id<>0 And organization_id = '1')
)temp2
Order By member_name, Tpc_TitlePlease help. Thank you.

Hi,
Recently the powers-that-be migrated the largest databases from one server to another, more powerful server while keeping some support data on the original server. My problem: I need to run queries on tables spanning both database servers. Unfortunately, I can't find any documentation on how to do this. Does anyone have any ideas?

I am currently building a website to deal with different product information and sales with php. I am using SQL to sort the database and pull out information.
The final thing i need to do is work out the total revenue of each product however the problem i am having is that the 'Price' column and 'SalesVolume' column are in two different tables and they need to be multiplied together.
The two tables and column headings are as follows:
Product
ID
Name
Price
MonthlySales
ID
ProductCode
Month
Year
SalesVolume
(ID and ProductCode are linked together in a relationship)
I cannot see anything wrong with the syntax in my query however i believe there is.
Here is the query I am using:
Code:
"SELECT SUM(Products.Price * SUM(MonthlySales.SalesVolume)) as revenue FROM Products
INNER JOIN MonthlySales ON(Products.ProductCode = MonthlySales.id) GROUP BY Products.ProductCode";

I am using the Dynamic Cross-Tab code supplied in an article from SQLServer Magazine (http://www.winnetmag.com/SQLServer/...608/15608.html).I modified the script to generate a temp table inside the storedprocedure, and then use this temp table as the source for thecross-tab. However, the problem seems to be that the dynamic SQLstring generated by the script is longer than what can be stored inthe @SQL variable. The Cross-tab works great, so long as the amount ofdata to be pivoted is small.Is there any way around this? E.g. a User defined type, or anotherdata type which can store more characters?Thanks,TimCREATE procedure CBN_CrossTab@StudyID varchar(100), --Model ID passed from web app - Only one modelcan be selected@Level int --The level to which the taxonomy should be rolled upAsDECLARE@Table as sysname, --Table to crosstab@OnRows as nvarchar(128), --Groupuing key values (on rows)@OnRowsAlias as sysname, --Alias for grouping cloumn@OnCols as nvarchar(128), --destination columns (on columns)@SumCol as sysname, --data cels@SQL AS varchar(8000), -- String to hold generated SQL String@NEWLINE as char(1) --Holds the New Line Character for the codeSET @OnRowsAlias = NullSET @SumCol = NullSET @NEWLINE = CHAR(10)-- Generate the Temp table for the taxa and countsCREATE TABLE #RefOrganisms (sampleid int, txtTaxa varchar(75),fltCount float)INSERT INTO #RefOrganisms(sampleid, txtTaxa, fltCount)SELECT dbo.tblsampledata.sampleid,dbo.CBN_RecursTaxa(dbo.tblbenthic.organism_tsn, @Level, " ") AS Taxa,SUM(dbo.tblbenthic.[count] /dbo.tblsitedetail.numberofreps) AS SumCountFROM dbo.tblstudylist INNER JOINdbo.tblsite ON dbo.tblstudylist.studyid =dbo.tblsite.study_id INNER JOINdbo.tblsitedetail ON dbo.tblsite.siteid =dbo.tblsitedetail.site_id INNER JOINdbo.tblsampledata ONdbo.tblsitedetail.sitedetailsid = dbo.tblsampledata.sitedetails_idINNER JOINdbo.tblbenthic ON dbo.tblsampledata.sampleid =dbo.tblbenthic.sample_id INNER JOINdbo.iter_intlist_to_table(@StudyID) i ONdbo.tblstudylist.studyid = i.number INNER JOINdbo.tblbenthictaxa ON dbo.tblbenthic.organism_tsn =dbo.tblbenthictaxa.tsnWHERE (dbo.tblsampledata.qaqc = 0) AND (dbo.tblsampledata.status =2) AND (dbo.tblbenthictaxa.rank_id >= @Level)GROUP BYdbo.tblsampledata.sampleid,dbo.CBN_RecursTaxa(dbo.tblbenthic.organism_tsn, @Level, " ")-- Identify the Temp table info for the CrossTabSELECT @Table = '#RefOrganisms'SELECT @OnRows = 'sampleid'SELECT @OnCols = 'txtTaxa'SELECT @OnRowsAlias = NullSELECT @SumCol = 'fltCount'--STEP1 BEGININNING OF SQL STRINGSET @sql = 'SELECT'+ @newline +' '+ @onrows +CASEWHEN @ONROWSALIAS IS NOT NULL THEN ' AS ' + @ONROWSALIASELSE ''ENDCREATE TABLE #KEYS(KEYVALUE NVARCHAR(100)NOT NULL PRIMARY KEY)DECLARE @KEYSSQL AS VARCHAR (1000)SET @KEYSSQL = 'INSERT INTO #KEYS ' + 'SELECT DISTINCT CAST(' +@ONCOLS + 'AS NVARCHAR(100)) ' + 'FROM ' + @TABLEEXEC (@KEYSSQL)DECLARE @KEY AS NVARCHAR(100)SELECT @KEY = MIN(KEYVALUE) FROM #KEYSWHILE @KEY IS NOT NULLBEGINSET @SQL = @SQL + ' ,'+ @NEWLINE +' SUM(CASE CAST(' + @ONCOLS +' AS NVARCHAR(100))' + @NEWLINE +' WHEN N''' + @KEY +''' THEN '+ CASEWHEN @SUMCOL IS NULL THEN '1'ELSE @SUMCOLEND + @NEWLINE +' ELSE 0' + @NEWLINE +' END) AS [' + @KEY + ']'SELECT @KEY = MIN(KEYVALUE) FROM #KEYSWHERE KEYVALUE > @KEYENDSET @SQL = @SQL + @NEWLINE +'FROM ' + @TABLE + @NEWLINE +'GROUP BY ' + @ONROWS + @NEWLINE +'ORDER BY ' + @ONROWSPRINT @SQL --+ @NEWLINE --FOR DEBUGEXEC (@SQL)GO

Hey guys. This is one of the queries pasted from BOL. I'm having problems excuting this query. The problem lies in the CROSS APPLY part. When I copy this query and run it in SSMS, it gives me an error saying 'Incorrect syntax near .' It doesn't like the qs.sql_handle part. If I remove that and pass the actual handle in for some query, it works. Can someone please tell me what I'm doing wrong?????? Also, I've sp1 installed on my SQL Server 2005 Enterprise, just in case if this matters. Below is the query pasted which is giving me problems. Thank you.
SELECT TOP 5 total_worker_time/execution_count AS [Avg CPU Time],
SUBSTRING(st.text, (qs.statement_start_offset/2)+1,
((CASE qs.statement_end_offset
WHEN -1 THEN DATALENGTH(st.text)
ELSE qs.statement_end_offset
END - qs.statement_start_offset)/2) + 1) AS statement_text

Hello All,
I have an issue where my SQL query is taking an exceedingly long time to execute. It joins tables in 2 different databases. When I import the tables from both my databases into a single database and execute the query, it executes instantly!
I had a look at the execution plans of the same query when executed within a single database and the query when executed with tables across databases and there were differences in the execution plan. The single database query had parallelism whereas the query for cross database joins didnt have any parallelism.
Both the databases are in the same server.
I havent seen a case where cross database joins impact query performance so much. Any pointers?
Thanks

I have information on clothes in a table that I want to select out to a result set in a different structure - I suspect that this will include some kind of pivot (or cross-join?) but as I've never done this before I'd appreciate any kind of help possible.
Current structure is:

writing a cross join query with one table:
Cities(City_name, X_coordinate, Y_coordinate)
the result should be all combinations without reverse column returns
SELECT * FROM [dbo].[Cities] as P1
Cross JOIN [dbo].[cities] as p2
where (p1.City_name != p2.City_name) and ???
for example if there are three Cities as A,B,C the result should be: A->B, A->C, B->C (without the returns B->A, C->A, C->B)
