Hi,
I forgot the syntax to to a self-join to find all rows that have
duplicate values. Could someone post the answer to the following example:
Column1
-----
x
y
z
x
After the select statment runs "x" would be the output.
Thanks,
Ken
I need to find all tables which has a join (either inside an sp, view, etc) with my given table in a db.
sys.dm_sql_referencing_entities doesn't work here.
Note: i dont want to identify by FK References, for 2 reasons:
1) tables might not met with a join (just FK was defined)
2) sometimes, a join happened between tables, without an FK defined
Hi Frinds,
How can i find out the no of rows in each table. if the no of table are more than thousands(i.e. 1000+,2000+ etc..) are there. Certainly 'select count(0) from <table>' is not the good idea. Egarly awaiting for the solution.
thanks

Yesterday, I had an occurence where someone (one of our developers :) ) deleted many vital rows in a database. I was able to recover via a backup but I'd like to see what was run to delete those rows, when and who if possible? I have the transaction log and the _log.ldf.
Can I read those somehow to find out this information? I have since added auditing to said tables, but I'd really like to go back and see what happened?
I do know about Lumigent, but is there a different production/solution?
Thoughts?
Thank you

I have this data as below. I need to find out the combination from the data and take a count of them
CREATE TABLE A
( nRef INT,
nOrd INT,
Token INT,
nML INT,
nNode INT,
sSymbol VARCHAR(50),
[code].....
if you can see, the rows with column nRefNo 1 and 3 are same i.e. with same combination of Symbol viz. Silver and Castorseed.
Hence the desired output will be
Symbol Count
Castorseed-Silver 8
How to get this combination together and then take count of them. Please note i will be dealing with more than 5 million rows.
I'm using this to find duplicates where a person has the same email but varying firstname and lastnames:
select distinct t1.booking_id, t1.first_name, t1.last_name, t1.email_add, t1.booking_status_id
from [aren1002].[BOOKING]
as t1 inner join [aren1002].[BOOKING]
as t2
on t1.last_name=t2.last_name and t1.booking_id<>t2.booking_id
where t1.booking_status_id = 330
order by last_name asc
Sample data:
3927 Greg Smith greg@emailno1.com 303
5012 John Smith greg@emailno1.com 303
6233 John Smith greg@emailno1.com 303
4880 Dulcie Abuud dulcie@theiremail.com 303
However it is listing the non duplicate rows, For example: The record with Abuud as the last name, doesn't have any duplicates in the table, so I don't want it listed.
The data should be like this:
3927 Greg Smith greg@emailno1.com 303
5012 John Smith greg@emailno1.com 303
6233 John Smith greg@emailno1.com 303
Given an ID (column B), I need to find which IDs have identical data.That is, given '200', I want the desired result to be:100The idea is that the system sees that id=200 has 5 records with theindicated data in cols C and D.It should then find any other ids with the exact same data for thosecolumns.Note, in this case, both 200 and 100 have (30:1, 30:2, 30:3, 40:4,40:5) so they match. 300 and 400 should NOT be returned.Any bright ideas out there?

Hi, I would appreciate help on the following query I got stuck with;
I've got 2 tables "AccountList" and "PeriodBalance";
I need to return all the accounts form "AccountList" and their balance form "PeriodBalance";
The user will select a period for which the balances should be returned, if there is no balance for the period... 0 should be returned. "PeriodBalance" would not have an entry if there is no balance for the period.
There is only 3 possible periods (1, 2 or 3)
And there is only one balance per period per account;
TABEL 1: AccountList:
AccNo
100
200
300
TABLE 2: PeriodBalance:
AccNo PerID PerBal
100 1 1000
100 2 1750
100 3 1800
300 1 3200
300 3 3500
This is what is what I need returned by the query, assuming we are selecting PerID 2: (WHERE PerID=2)
AccNo PerID PerBal
100 2 1750
200 2 0
300 2 0
I've included ISNULL(PerID,4) = 4 in my WHERE clause...this worked for returning AccNo 200.
My problem is AccNo 300 in not NULL....it has values, just not for the selected PerID...so how do I get AccNo 300 to be included in my Query result?
This is my SQL Query:
SELECT AccountList.AccNo, PeriodBalance.PerID, PeriodBalance.PerBal
FROM AccountList LEFT OUTER JOIN
PeriodBalance ON AccountList.AccNo = PeriodBalance.AccNo
WHERE PeriodBalance.PerID = 2 OR ISNULL(PerID,4) = 4
Thanks in advance;

What would be the most economy solution for this WHERE, I see the code where we have covnert to 101 type on both sides of equation, which I tnink is not right.
So I'm thinking to put it on the left like this, just curiouse is this the best solution, I also heard that TSQL interpret between even better , here I'm really care abour performance.

I am trying to build a association table (t2) to store a list of users
have viewed an item in my records table (t1). My goal is to send the
UserID parameter to the query and return to the user a read / not read
marker from the query so I can handle the read ones differently in my
.net code. The problem is that I cannot work out how to return anything
but the read data to the client. So far my stored proc looks like this
DECLARE @UserID AS Int -- FOR TESTING
SET @UserID = 219 -- FOR TESTING
SELECT t1.strTitle, t1.MemoID, Count(t2.UserID) AS ReadCount,t2.UserID
FROM t1
LEFT OUTER JOIN

WHERE t2.UserID = @UserID
GROUP BY t1.MemoID, t1.strTitle,t2.UserID
It works fine but only returns those records from t1 that are read. I
need to return the records with null values also! I may have built the
assoc table wrong and would really appreciate some pointers on what I
am doing wrong. (assoc table has rID, MemoID and UserID columns)
Please help!

Shouldn't it should still get me the fields from the row in tblSections that matches the ID I'm passing it?
How can I make it so that it does?

I have the following query:
select sq.*, p.numero, p.nombre
from paf p right outer join dbo.GetListOfSquaresForShippingLot(@lot) sq on sq.number = p.numero and sq.version = p.numero
The @lot parameter is declared at the top ( declare @lot int; set @lot = 1; ). GetListOfSquaresForShippingLot is a CLR TVF coded in C#. The TVF queries a XML field in the database and returns nodes as rows, and this is completed with information from a table.
If I run a query with the TVF only, it returns data; but if I try to join the TVF with a table, it returns empty, even when I'm expecting matches. I thought the problem was the data from the TVF was been streamed and that's why it could not be joined with the data from the table.
I tried to solve that problem by creating a T-SQL multiline TVF that is supposed to generate a temporary table. This didn't fix the problem.
What can I do? Does anybody know if I can force the TVF to render its data somewhere so the JOIN works? I was thinking a rowset function could help, but I just can't figure out how.
PLEASE HELP!!!!
Let me know if you want the code for the CLR TVF. This is the code for the T-SQL TVF:
CREATE FUNCTION [dbo].[GetTabListOfSquaresForShippingLot]
(
@ShippingLot int
)
RETURNS
@result TABLE
(
Number int, Version int, Position smallint,
SubModel smallint, Quantity smallint,
SquareId nvarchar(5),
ParentSquareId nvarchar(5),
IsSash smallint,
IsGlazingBead smallint,
Width float,
Height float,
GlassNumber smallint,
GlassWidth float,
GlassHeight float
)
AS
BEGIN
INSERT INTO @result
SELECT *
FROM dbo.GetListOfSquaresForShippingLot(@ShippingLot)
RETURN
END
Hi,
I have a problem with a Merge Join providing no output (when it should have 1890 rows). My Data Flow Task has 4 OLE Data Sources, 3 Multicasts, and 1 OLE Data Destination. I am experiencing the problem near the end of my data flow where two Multicasts create two parallel flows of data (see Level 1 below). I have two Merge Joins which join one leg from each multicast with a leg from the other multicast (see Level 2 below). Then the two remaining legs use a Merge to get my destination output (see Level 3 below).
I am experiencing my problem with the Merge Join (input A2, B2) --> (output C2) transformation. The Merge Join providing output C1 appropriately outputs 1890 rows, but C2 outputs 0 rows. Both Merge Joins are identical. The data is identically sorted prior to entering the problematic Merge Join and a DataViewer (Grid) verified that the data is appropriately entering in. Merge Join (input A2, B2) --> (output C2) has 667 rows as input A2 and 1890 rows as input B2 (using an inner join, just like the other merge join), but C2 baffles me with 0 rows of output (when it too should have 1890). I receive no Ouput errors and the execution completes showing all green.
Level 1
Multicast (output A1, A2) [667 rows]
Multicast (ouput B1, B2) [1890 rows]
Level 2
Merge Join (input A1, B1) --> (output C1) [1890 rows]
Merge Join (input A2, B2) --> (output C2) [0 rows]
Level 3
Merge (input C1, C2) --> (output D1) [1890 rows]*
I read about mysterious behavior with Merge Joins and have attempted modifying my EngineThreads property to values between 2 and 10, with no luck. Any help/ideas would be appreciated.
Thanks,
Devin
* Should be 3780 rows
I have a DB with some tables and, on certain tables, i've a column named "ID_COMPUTER".
I need to find all the rows where id_computer=<specific_value> from all the tables of my database, when column "ID_COMPUTER" exists.
Pseudo-code would be: select * from db.* where id_computer=<specific_value>
how to write this ?
write a query which retrieves only unique rows excluding some columns.

In the above table project number and id shouldn't be considered and I should get the unique rows considering rest of columns and sorted based on date. Expected result is
