Hello,
I'm trying to select the maximim value for certain zip codes, for example my table looks like this:
ZIP Category Value
90210 S1 5
90210 S2 10
90210 S3 2
90210 S4 3
10221 S1 24
10221 S2 3
And I want the end result to be each unique zip code with the category having the maximum value, for example 90210 S2, 10221 S1, etc
If I have a simple query like:
select * from bigtable
where product_code in ('abc','def','hij','klm')
I know that each of those product_codes will return a large data set. What I'd like to do is to run the same query but constrain the result set to a max rownum of 200.
Is this possible?
My team at work has spent the past week troubleshooting performance issues experienced by users of our asp.net 2.x web application. We've got a probe running on one of the web servers that has identified a frequently occuring error that no one has seen before and I can't find anywhere online. MSSQL error "system.data.oledb.oledbcommand.executenonquery(Maximum number of unique SQL exceeded) Has anyone here ever seen this error before?The web server, application, SQL servers and databases all seem to be configured properly, but users are experiencing latency and this frequently occurring error is a mystery to us.

I have a simple table:
Categories
----------
CategoryID
ParentID
Name
I want to associate my Products to a category so that I can search by category....ok. If I just have a simlpe table:
CategoryProducts
-------------------
CategoryId
ProductId
I can link a product to a category. Now, if I just link a product to a single category, such as the bottom leaf category:
Self Help / Personal Development / Spiritual / Meditation
I would link a product to the Meditation category. However if I
click on Self Help while browsing, I want to see all items underneath
Personal Development, Spiritual and Meditiation. So my question
is is this a good way to store the product-category relationships, or
should I put many entries into CategoryProducts to keep the queries
simlpe and faster? Are they faster doing it this way? In this way there
would be 4 entries for a product in meditation. My personal idea
is that adding all entries up a tree arm of a category path will be
cumbersome to manage, but it does solve the problem of clicking on Self
Help and seeing all products that exist within sub-categories. I
am sure an SQL query would be able to work this out, but I dont know if
performance would be something to consider on an ecommerce site? Are
there any patterns fo rthis stuff - seems a reasonably repeatable
pattern for business sites?
Thanks,
jr.

Hi Guys,
I am trying to insert a unique code, like a voucher code, into a table in MSSQL, 10 numbers (0-9) which obviously needs to be unique.
I can code this in ASP, but I think the process could be a bit long winded, i.e. create a key - run a stored procedure to see if it is free if not loop and check again. Surely there would be a way to do this in a stored procedure in one?
So the code would look like 3928492834.
1. Generate Key in SQL
2. Check if not used in column 'kcode' if it is, regenerate and check again.
Any advice would be greatly appreciated, I know how to do this in ASP but bit of a SQL newbie!
Thanks

Hi all,My program is a central data processing application built in ASP.We have different companies that use different web pages on another webapplication (from different countries) to load some inventory data(merchandise - clothes).Here is my requirement: Load different types of data (in differentformats) into a common set of tables, to do this I have to firstfilter, do lookup's, use cross-reference tables on this data and thenload it into a couple of tables.Since data is so different everytime, I want to have one main storedprocedure in which I can build the table (I know the format of thisdata so I know what columns/types to create) into which I will feed thedata.After this I will create other stored procs/udf's that reference thistable (probably from the same main stored proc) 'cleanse' the databefore loading into the actual tables.How feasible is my approach? (if you can call it one :-) I do not wantto have seperate tables for each country, that will be too many and sothis plan...If not any other ideas will be really helpful.thanks much

“The table "tbl_Intraday_Tmp" has been created, but its maximum row size exceeds the allowed maximum of 8060 bytes. INSERT or UPDATE to this table will fail if the resulting row exceeds the size limit” When I google this there seems to be a related to tables with vast numbers of columns.
My table tbl_Intraday_tmp is relatively small. It has 7 columns. 1 of varchar(5), 3 of decimal(9,3) and 2 of decimal(18,0). The bit I’m puzzled with is it was working and stopped.

Wondering if there is a physical or realistic limitation to the numberof UNION statements I can create in a query? I have a client withapprox 250 tables - the data needs to be kept in seperate tables, but Ineed to be filtering them to create single results sets. Each tableholds between 35,000 - 150,000 rows.

View 15 Replies View RelatedI am executing a SELECT statement that has about 500 characters of literal characters concatenated with the contents of a field from a table. I am then storing the result to be run as dynamic SQL. I am finding that when run this as select statement in query analyzer, the last part of the literal gets truncated. When I run it as a cursor and store it in a varchar(1000) variable and print the variable everything works fine. In addition when I put the select statement in a stored procedure and return this to a ADO recordset, the resultset is fine as well. But running the stored procedure in query analyzer truncates the results as well. The issue seems to be getting the results of the SELECT in query analyzer. Even running the stored procedure in the SQL area of Enterprise Manager returns a proper result. Has anyone heard of a maximum return from a select in query analyzer?

1. PhoneID is nothing but the participant in the call. PhoneID = 1 is twice from above. Which means 2 particpants (Same call )with 2 numbers with their callstarttime and callendtime. Similarly for PhoneID =2, there are 4 participants. And the list goes on for a day and then for a month.
2. For example a phone call P1 with 2 participants is going on for a particular day. We should not consider the same phone call having 2 participants involved. So that the concurrency would be 2. We have to ignore that here.
3. Only to be considered is other Phone calls for that day. Lets say P1 having call with 2 participants, P2 having some 4 participants which fall in the time period of P1. Then we should consider P1 and P2 the common period
4. In order to find number of concurrent calls happened for a day basing on callstarttime and callendtime. What would be the query?
5. Should consider the Timeperiod or the bucket with 1 hour as the period.
6. A Phone Call P1, Phone Call P2, should have matching (common) time ( keeping all the scenarios) is required for this query.
Result for Concurrent calls for a day should be like below. Should get all the concurrent connections happened for a particular day.
Date|TimePeriod/Bucket(hr part)|Concurrentconnections|
Jan-01-2015|01 to 02|3
Jan-01-2015|11 to 12|2
Jan-02-2015|04 to 05|5
Jan-02-2015|12 to 13|13
........
ii) So once the above is achieved.
Have to find the Maximum concurrent connections for day from the above.
For below Maximum Concurrent connections are '3'
Date|TimePeriod/Bucket(hr part)|Concurrentconnections|
Jan-01-2015|01 to 02|3
Jan-01-2015|11 to 12|2
Hence the Result for Maximum Concurrent Connections would be
Date|TimePeriod/Bucket(hr part)|MaxConcurrentconnections|
Jan-01-2015|01 to 02|3
Jan-02-2015|12 to 13|13

I have a problem with a SQL SELECT query. As far as my research goes i figured out that UNIQUE is used when you have one column that you whant unique and DISTINCT is used when you have more than one column that you want to all be unique. But i have a query where i want just some of the columns to be unique and some not. Here is the full query (It's in a stored procedure):
set ANSI_NULLS ON
set QUOTED_IDENTIFIER ON

SUM(dbo.Bond.LoanAmount) AS SumOfBondValue, COUNT(dbo.Bond.BondID) AS CountOfBond, dbo.ProgressStepType.ProgressStepType

dbo.TransactionTable ON dbo.BondGroup.BondGroupID = dbo.TransactionTable.BondGroupID INNER JOIN
dbo.Bond ON dbo.TransactionTable.TransactionID = dbo.Bond.TransactionID INNER JOIN
dbo.ProgressStep ON dbo.TransactionTable.TransactionID = dbo.ProgressStep.TransactionID INNER JOIN
dbo.ProgressStepType ON dbo.ProgressStep.ProgressStepTypeID = dbo.ProgressStepType.ProgressStepTypeID
WHERE (dbo.BondGroup.BondGroupID = @BondGroupID)

(dbo.ProgressStepType.ProgressStepType = 'Attorney') OR
(dbo.ProgressStepType.ProgressStepType = 'Feedback received from bank')
ORDER BY dbo.ProgressStepType.ProgressStepType
*********
With the DISTINCT it gives me a full set of unique values but what i want is this: Every CountOfBond may have more than one SumOfBondValue and they may be the same, but if there is more than one dbo.ProgressStepType.ProgressStepType the query should only read it once. In other words the dbo.ProgressStepType.ProgressStepType is a unique value and the rest not...

Hi, I have been asked to write some code that can check a large table for duplicate values in a non pk column. The table may have up to 1000000 rows. The PK column is an auto increment field. For performance reasons the column in question could not be set to unique values only for inserts, an algorithm is used to create unique no's before the insert but what I am doing is double checking that their have been no duplicates created accidently. If their are duplicates I need to know what rows they occurred on.
Thanks

View 5 Replies View RelatedHI all,
I am having a bit of difficulty trying to work how to write a query. I am normally only used to doing SELECT, UPDATE and DELETE queries ... the simple ones.
However I have come across a query whereby things get a lot more complex.
My company has an employee table with a way to store data that I have not been used to.
EMPLID, NAME, DATELASTMODIFIED, EmployeeStatus. (There are lots more but N/A)
The problem that I have is that there can be more than one row for an employee id. Therefore I cannot uniquely identify an employee id. Instead what I have discovered I have to use is to find an employee with the last modified date higher than the other rows with the same employee id.
The query I am trying to achieve is:
Code:
Count all employees that have an employee status of 'Employed'.
(Therefore counting only one employee per id rather than counting the same employee more than once)
The trouble is, translating this into a SQL query. I have tried to have a go but don't know how to query:
Code:
SELECT COUNT (DISTINCT EmplId)[
FROM Employeetable AS e
WHERE e.LASTDATEMODIFIED <And Stuck>
AND EmployeeStatus = 'Employed'
So I thought hmm lets pseudo code this, but then I get stuck into compelixty:
Code:
SELECT * FROM EmployeeTable WHERE EmployeeStatus = 'Employed'
int counter = 0;
ForLoop (EmplId)
{
LastDate Date
if(LASTMODIFIEDDATE > LastDate)
{
LastDate = LASTMODIFIEDDATE
}
//How do I return the value? Do I count the value?
}
Has anyone come across this issue before? Can anyone help it quite fundemental to what I have to query so help on this is highly appreciative.
