Using An Array To Determine Query Order??
Oct 17, 2006
Hi.
I have a VB.NET function that returns an array of Integers.
Say, FunArray = [2, 3, 5, 8, 6, 23, 1, 10, 20 , 4, 54]
One characteristic of the array is that no two numbers
repeat - it reflects the IDs of my Users table. And, that
it is not ascending or descending.
What I would like to know is how do I sort my query in
the order of the integers in this array? Ideally, I
would like to use ORDER BY for this query.
thanks in advance.

I am trying to determine the next available order id using the method below. It works provided the table has a record in it. If it doesn't I get the error "Input string was not in a correct format." I am certain that it is because the query is returning a value of NULL. How can get around that or check for the NULL value?' Establish data connection...Dim sqlConn As New SqlConnection(ConfigurationSettings.AppSettings("connectionstring"))'Determine order id number...Dim order_id As IntegerDim strSQL As StringstrSQL = "Select MAX(order_id) from mkt_order"Dim sqlCmd As New SqlCommand(strSQL, sqlConn)Dim sqlDA As New SqlDataAdapter(sqlCmd)Dim sqlDS As New DataSetsqlDA.Fill(sqlDS, "item")If sqlDS.Tables(0).Rows.Count <> 0 Thenorder_id = Convert.ToInt32(sqlDS.Tables(0).Rows(0)(0).ToString()) + 1Elseorder_id = 1End If

I'm working on a sproc that determines the next order id for a specified customer. The table has
custid int,
ordernum varchar(10)
Data is:
1000, 1000-001
1000, 1000-002
1001, 1001-001
1000, 1000-003
I need to know the next ordernum for the specified custid. For example, GetNextOrderNum(1000) should return 1000-004. GetNextOrderNum(1002) should return 1002-001 (since there aren't any orders yet).
I honestly don't know where to begin.
Can someone please help?

Does anyone have a script that analyzes primary and foreign key relationships of tables and produces a suggested load order based upon dependancies?
Thanks,

I am trying to order by the field and direction as provided by input parameters @COLTOSORTBY and @DIR while using a CTE and assigning Row_Number, but am running into syntax errors.
Say I have a table called myTable with columns col1,col2,col3,
Here's what I'm trying to do
with myCTE AS
(
Select
col1
,col2
,col3
,row_number() over (order by
case when(@DIR = 'ASC') then
case when @COLTOSORTBY='col1' then col1 asc
when @COLTOSORTBY='col2' then col2 asc
else col3 asc
end
else
case when @COLTOSORTBY='col1' then col1 desc
when @COLTOSORTBY='col2' then col2 desc
else col3 desc
end
end
from myTable
)
Please let me know what i can do with minimal code repetition and achive my goal of dynamically sorting column and direction. I do not want to use dynamic SQL under any circumstance.
Thanks.

All,
I am using Reporting Services 2005. One of my reports is getting the following error when I try to export to Excel. It will export to .CSV though.
"Destination array was not long enough. Check destIndex and length, and the array's lower bounds."
Any suggestions would be greatly appreciated. Please copy me at machelle.a.chandler@intel.com.

I am trying to determine which of three stored procedure designs arefastest in the Query Analyzer:One query is a straight SELECT query with all desired rows and a dozen(tblName.RowName = @param or @param = Null) filters in the WHEREstatement.One query populates a #Temp table with the UniqueIDs from the resultsof the SELECT query in the above example, then joins that #Temp tableto get the desired rows.One query users EXEC sp_executesql @sql, @paramlist, @paramin which the @param has the dozen filters.What I'm trying to determine is which is the fastest.Each time I run the query in Query Analyzer it returns the samerecordset (duh!) but with much different Time Statistics.Are the Time Statisticts THE HOLY QRAIL as far as determining which isfastest, and what so I want to look at, the Vale or the Average? Inotice there are different numbers of bytse sen and bytes received foreach of the three queries.Any illumination on this is appreciated.lq

I have a stored procedure that has a paramter that accepts a string of values. At the user interface, I use a StringBuilder to concatenate the values (2,4,34,35,etc.) I would send these value to the stored procedure. The problem is that the stored procedure doesn't allow it to be query with the parameter because the Fieldname, "Officer_UID" is an integer data type, which can't be query against parameter string type.
What would I need to do to convert it to an Integer array?
@OfficerIDs as varchar(200)
Select Officer_UID From Officers Where Officer_UID in (@OfficerIDs)
Thanks

Hi, I'm sorry if this is the wrong place to ask this question. These forums are overwhelming and I couldn't find the appropriate place to post.
I am wondering if there is some way to determine when a query has completed. What I want to do is use a PleaseWaitButton in asp.net when the user clicks to run a query and have the button reactivate after the query has completed. I know how to set a specific wait time but I do not want the user to have to wait a default time for the query to complete. Any help you may provide would be greatly appreciated.
Thanks!

I need a query that gets all of the databases on a server and determines if a backup has been taken. I would normally use the jobs query I currently have, but it wouldn't tell me when the last backup was taken for a new database. I think I should be able to use sp_helpdb or some table from the msdb database. Also, this has to work on SQL Server 2000/2005. If anyone has anything I'd be very grateful. Thanks in advance.

I'm looking for a way to pass an array of values as a parameter to a query in a table adapter. For example I want to run a query something like:SELECT * FROM menu WHERE menu_role IN (@roles)And I could pass something like 'RegisteredUser, SuperUser, OtherUser' to the @roles parameter.For some reason I can't figure out a way to do this. Any help would be greatly appericated.Thanks,Ryan.

I am trying to create a "Loan Ledger Card" in SSRS which does the calculation up to report extracting time. I was able to create it on Excel (Click to download the Excel file) as we can calculate amounts for each installment based on Row and Column name. You can test it by putting any amount (Here it should be below 62000 as it is the total balance of loan) in "Amount Paid" yellow cell and see the effect.
I have made a selection in SQL (attached query and result in screenshot). It calculates the total paid amount by now on the first row, and all due amounts in other rows. Basically, It should first deduct the interest from first row, then principle, same process for second row and so on until it covers the whole paid amount.
SELECT
'0' As RN
,memrepay.lnr
,'Repayment' AS Type
,SYSDATETIME() AS NOW
,SUM(memrepay.mprinc) As PrincPaid
,SUM(memrepay.mint) As IntPaid
[Code] .....
How can I do the similar calculation of Excel file in "SQL query" or "SSRS custom code"?

Is there any T-SQL Script or SP that would determine what tables public users have access to? I only ask because I would like to make sure that any users with public rights do not have access to SYSXLOGINS, SYSDATABASES, SYSOBJECTS, SYSCOLUMNS and mswebtasks tables. Thanks

Hey there.
I must write a stored procedure to update a table and want to make sure the ID used in both Acceptance and Production will have the necessary access. The ID will inherit it's access to the resource though a ROLE.
Wondering if there are queries out there that can traverse for example, the roles/id's that have access to it... Thx!

Given the data below, I have a couple needs:
1) Query to determine if any date ranges overlap (regardless of category, e.g., row ids 6 & 7 below)
2) Query to determine if any date ranges of the same category overlap
declare @t1 table (id int primary key, category int, start_date datetime, end_date datetime)
insert @t1 select 1, 1, '1/1/2015 12:00:00 AM', '1/15/2015 12:59:59 PM'
insert @t1 select 2, 1, '1/16/2015 12:00:00 AM', '1/31/2015 12:59:59 PM'

I'm using an SqlDependency so I'll get an alert when the data under a query changes. When the query does not meet the criteria spelled out here http://msdn2.microsoft.com/en-us/library/aewzkxxh.aspx then I immediately get a SqlNotificationEventArgs event with the "Invalid" note. This is good.
I would like to know that a query is invalid before I try it with my ASP.NET application. Is there a sproc I can give to my SQL developers so they can test that they haven't used any stuff that would invalidate SqlDependency? What I'm hoping is that there's already a system sproc which could be called...
exec sp_QueryInvalidForNotification "exec myTestSproc 99"
Does such a sproc exist? Or does anyone know how to write one?

Hi, have configured an ODBC linked server for an Adaptive Server Anywhere (ASA6.0) database.
I have to write a function (not a procedure) that receives a number (@Code) and returns 1 if it was found on a table in the linked server, or 0 if not. Looks very simple...
One problem, is that the queries on a linked-server must be made through the OPENQUERY statement, which doesen't support dynamic parameters. I've solved this making the whole query a string, and executing it, something like this:
SET @SQL='SELECT * FROM OPENQUERY(CAT_ASA, ''SELECT code FROM countries WHERE code=' + @Code + ''')'
EXEC sp_executesql @SQL
(CAT_ASA is the linked-server's name)
Then, i would use @@ROWCOUNT to determine if the code exists or not. But before this, a problem appears: sp_executesql is not allowed within a function (only extended procedures are allowed).
Does somebody know how to make what i want?? I prefer to avoid using temporary tables.
Thanks!

Hi, This is a diffcult issue to explain. I hope to make my problemclear to you.SITUATIONI'm building A SLA Query for a customer. This customer has an awkwardway to determine the SLA results ;-) Depending on a category which isstored in a headertable (Requests) a field and logic is determined howto get a proper Close_Date. This Close_date can be the closedate ofthe request. It is also possible that the close_date is a certaindetail record (Request_lines). Also It is possible that thisclose_date is the ordered_date of a certain line_item.DONE SO FARI have created a metatable with rules per category. With this rule iwould like to determine a close_date. This close_date will be used asparameter in a function from which i determine the total minutes howlong this request has endured.GOALI want to create something like this:SELECT id, getdiffSLA(@StartDate, GetCloseDate(some parameters))FROM...I've created the function 'GetCloseDate()' in which i want todetermine the closedate. In this function i want to determine therule. Execute the proper logic and get the date.This is what i'm trying to do in a function (this is one rule of many):......ELSE IF @iRuleNo = 2 --SAD_A_REQUEST_LINE.CLOSE_DATEBEGIN............SET @vcSQL = N' SELECT @max = MAX(Close_date)FROM samis.dbo.SAD_A_REQUEST_LINESWHERE Parent_Quote = ''' + @vcNumberPRGN + ''' AND Part_No In ('+@vcIN_String + ')'Exec sp_executesql @vcsql, N'@Max datetime OUTPUT', @max OUTPUTSET @dCloseDate = @maxELSE IF.........THE PROBLEMThis doesn't work and yeah i know i can't use exec /sp_executesql in afunction. But if i try this in a stored procedure i can't use this ina Query.SELECT id, storedprocedure FROM ... Doesn't work, also.An option is that i could create a cursor, loop every record and callthe stored procedure, get the close_date, execute my SLA calculationfunction, store the result in a temptable, use this temptable in thequery <pffff>.But the table consists of 200000 records (with a detailtable) andperformance is a issue. It's used for loading a datawarehouse and notin a OLTP system so a bit slow performance is allowed but not to much.SO how do i do this without using a cursor???GreetzHennie

Hi all,
Been having a good root around the forums and the site here and there's some real smart people on here, i'm hoping one or more of them can help me out. I'm expecting this to be a simple question for some of you, however it's way beyond me at this point!
Table Structure (abridged, relevant columns):
Orders:
Code:
[Orders](
[OrderID] [int] IDENTITY(1,1)
[OrderDateTime] [datetime]
[OrderSiteID] [nvarchar](255)
[OrderOffline] [bit]
[OrderSentToWP] [bit]
[OrderReceivedFromWP] [bit]
[OrderAuthorised] [bit]
[OrderCancelled] [bit]
[OrderApproved] [bit]
[OrderFraud] [bit]
[OrderDispatched] [bit]
OrderItems:
Code:
[OrderItems](
[OrderID] [int]
[ProductID] [nvarchar](255)
[Quantity] [int]
[Price] [real]
[Weight] [real]
Products:
Code:
[Products](
[ProductID] [uniqueidentifier]
[ProductCode] [nvarchar](255)
[ProductTitle] [nvarchar](255)
Product price is captured at time of order, so that reports aren't affected by discounts or promotions, and stored with the productid in orderitems.
I want to get a report between a set of dates and with certain flags set (see below example) and then get a list of unique products, quantity sold and sales values for that products. Results table would have 4 columns; ProductCode, ProductTitle, QuantitySold, Sales Value.
So far I have this:
Code:
SELECT Products.ProductCode, Products.ProductTitle, SUM(OrderItems.Quantity) AS QuantitySold
FROM Orders INNER JOIN
OrderItems ON Orders.OrderID = OrderItems.OrderID INNER JOIN
Products ON OrderItems.ProductID = Products.ProductID
WHERE (Orders.OrderDateTime BETWEEN '2007/01/01' AND '2007/12/31') AND
(Orders.OrderSentToWP = 1) AND (Orders.OrderReceivedFromWP = 1) AND (Orders.OrderAuthorised = 1) AND (Orders.OrderCancelled = 0) AND
(Orders.OrderDispatched = 1) AND (Orders.OrderApproved = 1) AND (Orders.OrderFraud = 0) AND Orders.OrderSiteID= 'someguid'
GROUP BY Products.ProductCode, Products.ProductTitle
Which gets my summed quantities, and I guess I could use ASP to multiply that by the current price, but that defeats the point of setting the database up properly in the first place! I know how to design data, i just don't know how to get it back out again
I could most likely just do the whole thing in ASP and get it to output the correct answer, so if it's impossible/very difficult to do it in pure SQL then I'll go that route. Ideal situation would be a stored proc or saved query that I can pass a start date, an end date and a siteid to and that will get me the answers I want!
Thanks in advance to anyone that looks at this for me.
Also, any recommended books/sites to learn this kind of query?

Greatful for any help....
Have the query below which is taking delimited address information from _Venue column. This works well apart from the order it is returned, for example, the output below has the address tittle displayed in a different column for each row
Queen Elizabeth's Hunting Lodge is in Address1
All Saints' Church is in Address2
Audley End House is in Address3
As I need to reference from the query the correct part of the address from the same location each time, is there anyway to get around this?
Thanks in advance
SELECT coalesce (PARSENAME(REPLACE(_Venue,',', '.'),4), '-') address1
,coalesce(PARSENAME(REPLACE(_Venue, ',', '.'),3), '-') address2
,coalesce(PARSENAME(REPLACE(_Venue, ',', '.'),2), '-') address3
,coalesce(PARSENAME(REPLACE(_Venue, ',', '.'),1), '-') address4
FROM table

SELECT Column1,Column2,Column3 ....
FROM vwMyView
ORDER BY CreatedDT
View has about 10000 rows, If I remove order by query runs faster but adding an order by cause query to timeout..
All tables have clustered index based on the primary key of the table..
(a) Should I create an index view with CreatedDT as non clustered index?
(b) Or create a non clustered index on CreatedDT column on the underlying table?
I can provide DDL but if something obvious I am missing

I have a query with many (approximately, 30) conditions, such as:
select ....... from table1 join table2 on ( (table1.field1 = table2.field1 OR table1.filed1 IS NULL) AND (table1.field2 = table2.field2 OR table1.filed2 IS NULL) )
My question is:
In C++ or C#, when I write a condition like this, say, in an IF or WHILE, I know that I would be better off specifying the IS NULL (well, == null, to be precise) first, and use | instead of ||. In that case, the first condition (equality to null) is checked first, it's fast, and if it's not satisfied, the control flow goes to the next statement.
The question is, is there the same rule in T-SQL?
I mean, if I put the "... IS NULL" first, and then "OR ... = ...", will the query run faster than if I write it the other way around (that is, "... = ... OR ... IS NULL")?
This is very important to me, because most of those fields are VARCHAR, and due to some business rules, I can't change them to numerics etc, which would be compared much faster than text. So, even if I use full text search, I still need to find a way to optimize the query for performance...
By the way, I know that I can put those conditions in the WHERE clause, but as far as I know it won't make much of a difference for performance. So, my question is primarily about the order of conditions, in which SQL Server constructs its query plan.
[Edited:] In other words, what runs faster: comparing varchar to null or comparing varchars? And does it make a difference if I switch their places in my sql script?
We are using SQL Server 2000 SP4, Standard Edition. [Dev edition on the dev machine.]
Could someone kindly advise me on this, please?
Thank you ever so much.

I have some data that I'd like to order by a certain attribute.. but if there is a tie, then it should order by a secondary attribute.. and if there's still a tie.. then a 3rd attribute.
Currently the query looks like this:
SELECT * FROM Players WHERE ORDER BY Points
But I want it to look something like this (I know this doesn't work.. but it's just to give an idea):
SELECT * FROM Players WHERE ORDER BY (Points desc AND Games asc AND Goals desc)
Does anyone know the proper syntax for a multiple ORDER BY query like I described above?
