Aggregate Concatenation In SQL 2000 Vs 2005
Dec 10, 2007
I have created a UDF in SQL 2000 to implement a String Concatenation in an aggregate query. It works fine, but with the large data set I am using this against, it is very SLOW. (I also tried using a Cursor in a SP but that was even slower!)
I have seen several articles on the web about performing aggregate concatenation in SQL Server 2005 using either the PIVOT function, XML, or the Common Language Runtime (CLR).
Does anyone know how much better these statements perform in SQL 2005 over the method I am using in SQL 2000? If it is significantly higher performing in 2005 this may push us to upgrade our system to use it.
Thanks,
Mike

Are we actually going to get a string concatenation aggregate in SQL Server 2008?? I am so sick of having to write a UDF for every concatenation I want to do. I am well aware of all the methods available to do it now, and they are all junk, and the performance is horrible. I'm sure it is a challenging problem, and there are known pitfalls, but its time to address these.
The notion that it is the responsibility of the front end to do the concatenation is pure bs. You don't dump 10,000 rows to your report server when you only need to display 1000, just so you can concatenate one lousy column.
I want to be able to write:
SELECT CustName, SUM(ProductPrice), CONCAT(ProductName, [my separator], ORDER OVER ProductName ASC)
FROM Orders
And I'm not going to stop complaining til I get it! (-;

How do I aggregate a column by concatenation?
/*
SQL Server 2000 datbase
I have 3 tables.
A "client" table.
A "call history" table.
And a "call detail" table.
The "client" table contains data about individual clients.
The "call history" table contains data about calls to or from the clients in the "client" table. (This is a one-to-many relationship of client-to-history interactions.)
The "call detail" table contains detail data about a particular "call history" entry. (This is also a one-to-many relationship of history-to-detail entries.)
*/
Code:
DECLARE @Client TABLE (ClientID INT PRIMARY KEY, ClientName VARCHAR(100))
INSERT INTO @Client
SELECT 1 [ClientID], 'Client A' [ClientName]
UNION ALL SELECT 2, 'Client B'
UNION ALL SELECT 3, 'Client C'
UNION ALL SELECT 4, 'Client D'
SELECT c.ClientID, c.ClientName
[Code]....

Is there a limit to how much text you can concatenate (other than datatype limits, of course)? For example, if you write:SELECT 'This is some text from: ' + Convert(char(15), SomeFieldName01)+ 'some more text' + Convert(char(25), SomeFieldName02) + 'yet moretext.' As BigNoteFROM TableIs there a limit on how much you can concatenate into that big notefield, meaning is there a limit other than the size of the data type?

Is it possible to define your own function? If so could you give me an example.
Keep in mind that I said in SQL Server 2000. I want no CLR SQL Server 2005 solutions.

I have 2 Dimensions in SSAS (see below end), I want to create a calculated member, named
This_Year_Billable_Objective_Count, with its formula = BillableLastYear*(100+ BillableObjective)/100.
The first factor, BillableLastYear is a number, aggregated (sum) from child units.
The second factor, BillableObjective is a percent number (for example 28 means 28%), it's not aggregate. It's an dependent value for each unit.
How can I calculate This_Year_Billable_Objective_Count for each unit?

Hi
We would like to install Sql 2005 Enterprise Edition (including database engine, reporting service, integration service and analysis service) as a sepearte instance on a server which already has Sql 2000 with reporting services and analysis services. We do not want to disturb the existing sql 2000 setup.
If we do that then what will happen to my earlier sql 2000 reporting service? Will it be upgraded to sql 2005 reporting service? I heard that reporting services are instance unaware application. Where will be the default reporting service database available?
Please help us.
Regards,

I am attempting to move some SQL 2000 databases to SQL 2005. My main production database does not seem to want to move. When I use the SQL 2005 GUI the .bak backup file is marked 'Incomplete'. When I attempt to restore the backup file I get a 'RESTORE detected an error on page (0:0) in database' message. I saw a thread in the SQL Express forum suggesting trying to restore from the T-SQL level to get the GUI out of the picture and I get the same 'error on page (0:0)' message. However when I take the same file and use SQL 2000 Enterprise Manager it restores with no problems.
Any ideas?
Thanks

Hi, I am trying to edit some data from a SQL2000-datasource in ASP.NET 2.0 and have a problem with a column that has bit-data and is used for selection. SQL2005 works fine when declaring <SelectParameters> <asp:Parameter DefaultValue="TRUE" Name="APL" Type="boolean" /> </SelectParameters>When running this code with SQL2000, there are no error-msgs, but after editing a record the "APL"-column looses its value of 1 and is set to 0. Looks like an issue with type-conversion, we've hit incompatibilities between SQL200 and 2005 with bit/boolean several times before. So, how is this done correctly with SQL2000? (I've tried setting the Type to "int16" -> err. Also setting Defval="1" gave an err) ThanksMichael

I have to merge the data from two databases, one is in SQL Server 2005 format, one is in 2000. The merged data will then reside on a SQL Server 2000 platform. Is there an easy way to do this through Management Studio or Enterprise Manager? Or will we have to export the data from the 2005 database to a flat file and import it into a new 2000 database. And then do the merge?
TIA

I am in the process of migrating from Sql Server 2000 to 2005. Part of my plan is to move some database's to 2005, but use the 2000 compatibility mode for the short term. My issue is this, our DR boxes are still on SQL Server 2000, would I still be able to use our log shipping processes? Or would I be better off in starting with migrating the DR boxes to 2005 first?
Thanks in advance.

I need to concatenate two date fields so they appear in a drop-down list like this: 8:00 AM - 10:00 AM
I'm using MS SQL 2005 and my query looks like this: SELECT ClinicTimesID, ClinicID, (CTStartTime + ' - ' + CTEndTime) AS TimeSlot FROM Clinics_Times WHERE (ClinicID = 1) and I get this error: Msg 242, Level 16, State 3, Line 1
The conversion of a char data type to a datetime data type resulted in an out-of-range datetime value.
Can I strip out the date so that only the time appears or is it even possible to concatenate these fields? If so, how?
Thanks!

I am completely new to SQL and I have some syntax questions. I am trying to concatenate 4 fields and some padded constants to form a new key field to perform joins. The result should be a twelve character field without spaces. My problem is that the current fields use spaces as place holders and I need to replace the spaces with ‘0’.
[RD_ID] nvarchar length 5
[RDWY_ID] nvarchar length 1
[MLGE_TYPE] nvarchar length 1
[OVLAP_MLGE_CD] nvarchar length 1
Concatenate 12 characters
1st ‘0’ (constant)
2nd, 3rd, and 4th, from [RD_ID] (without the suffix)
5th and 6th from [RD_ID] suffix or replace spaces with ‘00’
7th 1 or 2 from [RDWY_ID]
8th Z from [MLGE_TYPE] or replace space with ‘0’
9th 1 – 9 from [OVLAP_MLGE_CD] or replace space with ‘0’
10th ‘S’ (constant)
11th ‘0’ (constant)
12th ‘0’ (constant)
Results should resemble
0001CQ100S00 or 000100100S00
This is the query I used in Access.
LRS: "0" & IIf((Len(LTrim(RTrim([HITIS2_TVCLEAR2]![RD_ID])))=3),LTrim(RTrim([HITIS2_TVCLEAR2]![RD_ID])) & "00",LTrim(RTrim([HITIS2_TVCLEAR2]![RD_ID]))) & [HITIS2_TVCLEAR2]![DIR_RDWY_ID] & IIf([HITIS2_TVCLEAR2]![MLGE_TYPE]=" ",0,[HITIS2_TVCLEAR2]![MLGE_TYPE]) & IIf([HITIS2_TVCLEAR2]![OVLAP_MLGE_CD]=" ",0,[HITIS2_TVCLEAR2]![OVLAP_MLGE_CD]) & "S00"

Hi All,
I've been trying to create a dynamic query using the 'Like' clause and '%'.
my code snippet looks like this:
while (@@FETCH_STATUS = 0)begin set @likeString = @likeString + ' item_Text LIKE ''%'+@word+'%'' OR ' fetch next from theLike into @word end
-- strip off last ORset @likeString = ltrim(rtrim(substring(@likeString, 0, (len(@likeString) - 3))))-- ================================================-- create query to find keywords in the index and store in temp table-- ================================================set @query = 'INSERT into #resulttable (itemcount, item_id) SELECT COUNT(d.item_id), d.item_id FROM tp_index_details AS d INNER JOIN tp_index ON d.idx_id = tp_index.idx_id 'set @query = @query +' WHERE (d.idx_id IN (SELECT idx_id FROM tp_index AS i WHERE ( 'set @query = rtrim(@query) + @likeStringset @query = @query + ' ) AND (subscription_id = 1000))) GROUP BY d.item_id ORDER BY d.item_id DESC'
The problem is the @query string gets truncated. My question is how to get the quotes around '%' variables to work in a string?
Thanks for any help!

Hi all - I have posted inquiries on this rather vexing issue before, so I apologize in advance for revisting this. I am trying to create the code to add the parameters for two CheckBoxLists together. One CheckBoxList allows users to choose a group of Customers by Area Code, the other "CBL" allows users to select Customers by a type of Category that these Customers are grouped into. When a user selects Customers via one or the other CBL, I have no problems. If, however, the user wants to get all the Customers from one or more Area Codes who ALSO may or may not be members of one or more Categories; I have had trouble trying to create the proper SQL. What I have so far:Protected Sub btn_CustomerSearchCombined_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles btn_CustomerSearchCombined.Click Dim CSC_SqlString As String = "SELECT Customers.CustomerID, Customers.CustomerName, Customers.CategoryID, Customers.EstHours, Customers.Locality, Category.Category FROM Customers INNER JOIN Category ON Customers.CategoryID = Category.CategoryID WHERE " Dim ACItem As ListItem Dim CATItem As ListItem For Each ACItem In cbl_CustomersearchAREA.Items If ACItem.Selected Then CSC_SqlString &= "Customers.AreaCodeID = '" & ACItem.Value & "' OR " End If Next CSC_SqlString &= "' AND " <-- this is the heart of my problem, I believe For Each CATItem In cbl_CustomersearchCAT.Items If CATItem.Selected Then CSC_SqlString &= "Customers.CategoryID = '" & CATItem.Value & "' OR " End If Next CSC_SqlString = Left(CSC_SqlString, Len(CSC_SqlString) - 4) CSC_SqlString &= "ORDER By Categories.Category" sql_CustomersearchGrid.SelectCommand = CSC_SqlString End SubAny help on this is much appreciated, many thanks --

I'm trying to implement a system where I want to use something like a group by with a concatenation clause.
e.g.
Table 1.
ID Field
1 null
2 null
Table 2.
ID Value
1 AAA
1 BBB
2 CCC
2 DDD
2 EEE
Using one query I would like to transform Table 1 to
ID Field
1 AAABBB
2 CCCDDDEEE
Is there any way of doing this ? At the moment I'm using two cursors to accomplish this task, but this is not really efficient.

I am using the following sql statement to concatenate fields from a sql server in my query.
SELECT RTRIM(title) + ' ' + RTRIM(fname) + ' ' + RTRIM(lname) AS name, id FROM contact
2 questions:
1. How can I avoid a Null name field resulting from either fname or lname being Null? One Null field in the contatenation yields a Null field, even though the other field is not Null.
2. Does concatentation in the sql statement reduce performance significanlty?
