DB Engine :: Double Row Added From A Source Table That Did Not Have Double Record
Aug 28, 2014
Every night we connect to a remote server using Linked Server and copy details from that database to a loading table, then load it into the 'real' table in our own environment. The remove database we load it from has indexes/primary keys that match the 'real', however the 'loading' table itself does not have any indexes or primary keys, both are SQL Server 2005 machines.
In the loading table we first of all truncate it then do a select insert statement from the remote server, then we then truncate the 'real' table and load iit from the 'loading' table.
The issue is when we attempted to load it into our 'real' table from our loading table there was a duplicate row, and our process failed with a Primary Key violation.
I checked the source with does have the same primary key's in, it did not contain a duplicate row and I checked the loading table and that did contain a duplicate row.
My question this is in what circumstances this could happen ?

I am performing a series of calculations where accuracy is very important, so have a quick question about single vs double precision variables in SQL 2008.
I'm assuming that there is an easy way to cast a variable that is currently stored as a FLOAT as a DOUBLE prior to these calculations for reduced rounding errors, but I can't seem to find it.
I've tried CAST and CONVERT, but get errors when I try to convert to DOUBLE.
For example...
SELECT CAST(1.0/7.0 AS FLOAT)
SELECT CONVERT(FLOAT, 1.0/7.0)
both give the same 6 decimal place approximation, and the 6 decimals make me think this is single precision.
But I get errors if I try to change the word FLOAT to DOUBLE in either one of those commands...
SELECT CAST(1.0/7.0 AS DOUBLE)
gives "Incorrect syntax near )"
SELECT CONVERT(DOUBLE, 1.0/7.0)
gives "Incorrect syntax near ,"

I am attempting to reach some Clipper tables through a 32-bit ODBC driver from a 64 bit SQL Server. As there is no 64 bit driver offered for Clipper, I am pursuing a solution similar to the one described here:
Creating a Linked Server with 64 bit SQL Server 2008 to MS Access
It involves using a SQL Express 32 bit instance as a bridge.
I have created a Linked Server on the 32 bit instance MTESTXPRESS as follows:
EXEC sp_addlinkedserver @server = N'ABDATA', @srvproduct=N'DataDirect 4.1', @provider=N'MSDASQL', @datasrc=N'ABServerCA'
On the 64 bit instance ALISTESTER I have another Linked Server as follow:
EXEC sp_addlinkedserver @server = N'ABACUS', @provider=N'SQLNCLI', @datasrc=N'ALISTESTERMTESTEXPRESS'
The suggestion is to then use a select statement such as:
SELECT * FROM OPENQUERY(ABACUS, 'SELECT COUNT(*) FROM ABDATA...ABBATCH')
Unfortunately, the DataDirect driver for MTESTEXPRESS will not recognize the 'ABDATA...ABBATCH' 3-part naming convention. The error message is:
An invalid schema or catalog was specified for the provider "MSDASQL" for linked server "ABDATA"
Is there some other way to select from the MTESTEXPRESS linked server?

In my asp.net page when I run a query against the database the datagrid get populated with only the records that starts with the first letter for example A good day. But none of the records that starts like this "A fine day" or "A nice day" displays in the datagrid. I tried to replace the Double Quote but it still returns only the records without " quotes. My query looks like this:
Dim queryString As String = "SELECT [Articles].[AN], [Articles].[Department], [Articles].[ArticleHeading], [Articles].[AccessLevel], [Articles].[Status] FROM [Articles] WHERE (([Articles].[AccessLevel] <> 'SysAdmin') AND ([Articles].[Status] = 'Enable') AND (REPLACE([Articles].[ArticleHeading], 'chr(34)', '')) like @ArticleHeading) ORDER BY [Articles].[ArticleHeading]"

Tables :
EmailUsers
ID int - PK
Email nvarchar(256)
ListsUsers
ListID int - FK to List Table - Combo PK
UserID int - FK to EmailUsers Table - Combo PK
When a person adds a user I need to:
A. insert them as a new entry into EmailUsers - no problem
B. insert their EmailUsers.ID from step A and ListID (passed in parameter) into ListsUsers - not so easy
C. if they're already in EmailUsers don't insert them but pass their existing EmailUsers.ID to part B
Any thoughts or examples I can follow? Maybe it's easier to do two seperate queries and control the if exists logic in asp.net?

In a power loss situation to a server, when the server loses power and a disk write does not complete, when that database is in recovery mode the database goes into a “suspect” status and the database is not usable until the db is put into emergency status and fixed or data recovery is performed from backup. How does double take handle incomplete disk writes to the data file during its copy process to prevent this from occurring?Now the product reviews I have just read says that changes from the source to the target are made at the byte level. So if a byte is changed, that byte is moved to your target server. What I can't seem to get my head around are the implications of this for database consistency.Anyone have any light to shed for me?

Hello all!
I have three columns of data... Test Name, Test Parameter, Test Result.
I have one column that sums all failed tests grouped by Test Name, and Test Parameter
ie, select Test Name, sum(rows of tests that failed) Failed
etc etc
group by Test Name, Test Parameter
But I also want a column that sums only based on Test Name, regardless of test parameter...so should I try to do something like "sum(Failed)" group by Test Name....in some kind of sub query, or what would you suggest? I know there will be duplicate entries.
Thanks for any help

I have 2 tables ZIPCROSS and HOUSEHOLDS. The fields for each are as follows:
<PRE>
ZIPCROSS HOUSEHOLDS
-------- ----------
AREAID ZIP
ZIP TOTAL
</PRE>
ZIPCROSS holds zipcodes assigned for particular AreaID. HOUSEHOLDS contains TOTAL number of household in each zipcode.
Now, I need to build a query that returns SUM of TOTAL for a given AREAID grouped by SCF (first 3 numbers of the zipcode) and SUM of TOTAL for a given SCF. Thus the results should look something like this:
<PRE>
AREAID SCF TOTAL SCFTOTAL
------ --- ------- ---------
1 900 1234 43210
1 901 2345 54321
</PRE>
etc... I can write a query that can get the right TOTAL or the right SCFTOTAL but not both on one query. The following query gives me the right SCFTOTAL but not TOTAL.
SELECT A.AREAID, LEFT(C.ZIP,3) AS SCF, SUM(D.TOTAL) AS TOTAL, SUM(E.TOTAL) AS SCFTOTAL
FROM AREAORDER A JOIN ZIPCROSS C ON A.AREAID=C.AREAID
JOIN HOUSEHOLDDATA D ON C.ZIP=D.ZIP
JOIN HOUSEHOLDDATA E ON LEFT(C.ZIP,3)=LEFT(E.ZIP,3)
WHERE A.MAILINGORDERID=133
GROUP BY A.AREAID, LEFT(C.ZIP,3)
ORDER BY A.AREAID, SCF
I'm aware of why this doesn't work but I can't seem to find the right approach. Any solutions? TIA.

I have some data -- counts ID'd by location and grid East like this --Loc East NCA 100 3CA 103 5CA 109 2CA 110 3I'm interested in the total of N on either side of the largest gap inEastings.In this case the largest gap is 6 (between 103 and 109), and the sum ofN for the 2 rows below the gap is 8, and for the 2 above the gap it's5.The problem is to locate the largest gap, and compute the sum of N forthe cases on either side. There are multiple locations, multipleEastingsper location, but only one largest gap. (If there are two largestgaps, itdoes't matter which one is used for the sums.)I can do this with multiple passes -- first locate the largest gap,then goback and locate the Eastings on either side, then sum up the Ns.That'srealy clumsy, I can't figure out how to do it more quickly, and I'm notsurewhat I'm doing is right. Any help would be appreciated.Thanks,Jim Geissman

I need some help with a double pivot problem. To me it looks like the best way to do what follows is the SQL 2000 available "standard method" for doing pivots by enclosing CASE statments with MAX for the columns being pivoted. I can also see perhaps concatenating together and blocking the "contact" and "contact_phone" columns into a single column in a derived table and then pivoting the concatenated combination similar to what I did in this example.
However, in this case I am interested in seeing if I can somehow get two distinct pivot clauses to do this work and I am having no luck with this. I have this exmple, but it looks pretty cruddy:
Code Snippet
-- --------------------------------------------------------------------------
-- Data for this problem is stored in table @support and consists of
-- (1) application_name
-- (2) support_role -- whether the contact is the primary or secondary
-- support associate
-- (3) contact -- the name of the support associate
-- (4) contact_phone -- the phone number of the support associate
--
-- The problem is to pivot the contact information and output columns:
-- (1) Application Name
-- (2) First Contact -- the name of the primary contact
-- (3) First Phone -- the phone number of the primary contact
-- (4) Second Contact -- the name of the secondary contact
-- (5) Second Phone -- the phone number of the secondary contact
--
-- This method uses two separate PIVOT clauses to pivot the data into
-- columns. This looks pretty cruddy.
-- --------------------------------------------------------------------------
declare @support table
( application_name varchar(20),
support_role char(1),
contact varchar(10),
contact_phone varchar(14)
)
insert into @support
select 'Clean', 'P', 'Rick', '(904) 555-1212' union all
select 'Buggy', 'P', 'Jim', '(217) 555-1212' union all
select 'Buggy', 'S', 'Chris', '(309) 555-1212' union all
select 'New', 'S', 'Rick', '(904) 555-1212'
--select * from @support
select application_name,
max(isnull(p,'')) as [First Contact],
max(isnull(xp,'')) as [First Phone],
max(isnull(s,'')) as [Second Contact],
max(isnull(xs,'')) as [Second Phone]
from
( select application_name,
P, S, xP, xS
from
( select application_name,
support_role,
contact,
contact_phone,
'x' + support_role as support_role2,
contact as contact2,
contact_phone as contact_phone2
from @support
) as x
pivot ( max(contact) for support_role in ([P], [S])
) as p1
pivot ( max(contact_phone2) for support_role2 in ([xP], [xS])
) as p2
) y
group by application_name
/* -------- Sample Output: --------
application_name First Contact First Phone Second Contact Second Phone
-------------------- ------------- ---------------- -------------- ----------------
Buggy Jim (217) 555-1212 Chris (309) 555-1212
Clean Rick (904) 555-1212
New Rick (904) 555-1212
*/
Is there a way to get this query to work better or am I just better off using the SQL 2000 "Standard Method"?

I have run into a somewhat pain in the posterior situation.
We have an app that currently uses SQL Server authentication. The application also uses a linked server. Now, we would like to move to a Windows authentication type of set up, but from what my network guys tell me is that AD doesn't support a "double hop".
In reading what's out here, I'm getting the impression that Kerberos needs to be enabled or delegation?
Does anyone know of somewhere I can find some good instructions on how to configure my SQL Server(s) to support the double hop?
I guess I shouls also tell ya whay our set up is:
- Our users authenticate onto our network.
- They then authenticate into Citrix.
- From Citrix they authenticate into SQL Server.
- Then there's the linked server.
So essnetially the hops woulg look like this:
Citrix to Database1 is HOP 1
Database1 to Database2 is HOP2
Thanks!!

Experts,
i have trouble while insert/update a field which contains double-byte characters (Chinese Traditional).
NO PROBLEM if i m using Enterprise Manager to view/edit the data. They are retrieved properly in the following:
(1) Enterprise Manager
(2) Query Analyzer
(3) Visual Basic
(4) Command prompt isql
EACH of the Chinese words are become a qustion mark '?' if the UPDATE SQL or stored procedure executed in the following:
(2) Query Analyzer
(3) Visual Basic
WHILE (4) Command prompt isql does not have the problem for the same UPDATE SQL and stored procedure.
Do you have any idea?

Hello all,
I am using SQL Server 6.5 SP5a.
I have to use bcp to import two text files everyday for database update. The problem is that some of the character fields that are being imported have double-quotes and/or commas in them. When these are imported into the SQL Server tables additional double quotes are being added into these strings.
Example:
INCOMING STRING = a"a
IMPORTED STRING = "a""a"
INCOMING STRING = b,b
IMPORTED STRING = "b,b"
I have searched through BOL and have not been able to find any information.
Does anyone know what is causing this and if so how to correct it?
Thanks,
Bryan Ziel

Over some time now, I've been developing a fairly hefty stored procedure, that does a lot of computations, and fairly few table lookups.
When I look at the performance on my server (a dual Xeon HT) I can see that it only uses 1 out of 4 possible "cpus" to work on the calculations, while the three others idle out, and was wondering if I can somehow force it to use max available CPU power?
