Updating Based On A Select Iteration
Jan 8, 2001
Okay I'm going nuts.
I have a table with a max key value in it, and another table with a few rows in it. I'm trying to update the two new rows with key values that are iterative from the MAX value in the first table. Could anyone point me to some good LOOP...UPDATE, etc resources or pointers before I go postal?
::grins::
Example: first table has a key field, last value in it is say 1000. The second table has two records. They need keys too, and those keys need to start at the last value in the first table + 1, so 1001, and end on the last row of the second table, or, say 1002. I cannot figure out how to read the last value of the first table, and create an update loop to iteratively update the key value in the second table based on the max value of the first, and looping based on the number of records in the second, in this case 2.
Arrrg!

I have a table in SQL server which has two rows. One has an ID of 'Bag CL55412'. Another has an ID of 'Bag CL55412-Cpy'. The Price for the first one is $99.99. I want to make the price for the second one 2% more & $.99 more.
The data looks like this
IDChannelPriceCompanyID
Bag CL5541299.99111
Bag CL55412-Cpy102.99500
The SQL to select that formula looks like this.
SELECT [ID]
,[ChannelPrice]
,(CEILING([ChannelPrice]*1.02)+.99)
,CompanyID
FROM [SC].[dbo].[Product]
WHERE ID like '%CL55412%'
To Update, I can think of something like this, but it will update based on itself, not a different row in the table.
UPDATE [SC].[dbo].[Product] SET ChannelPrice=(CEILING([ChannelPrice]*1.02)+.99)
How would I get it to update as I want it to? The origin CompanyID will always be 111 & the destination company ID will always be 500 for all of the respective rows that need to be updated

Hi People,
hope someone can help me out here with a little problem.
Basically i've go a asp.net page which has a listbox on. This list box is populated from a SQL database table with the datetime of the a selected field. Thus in the list box you get a list of strings looking like this "24/09/07 12:58"
Also on the page is a submit button, and some other editing textboxes. The main issue here is the when the submit button is used i get the currently selected listbox timedate string and then pass this along with other items to update a record in the database based on the datetime in the listbox control.
Below is how i get the string from the listbox control
Dim except_time As DateTime
except_time = DropDownList1.SelectedValue
The expect_time is then passed to store procedure along with some other vars, which looks like this
-- =============================================-- Author: Lee Trueman-- Create date: 1st Sept 2007-- =============================================CREATE PROCEDURE [dbo].[spExcept_UpdateData] -- Add the parameters for the stored procedure here @validated bit, @update_time datetime, @except_time datetimeASBEGIN -- SET NOCOUNT ON added to prevent extra result sets from -- interfering with SELECT statements. SET NOCOUNT ON
-- Insert statements for procedure here UPDATE exceptions SET validated = @validated, update_time = @update_time WHERE (except_time = @except_time)END
So validated and update_time should be updated when except_time is equal to @except_time
My problem is that the database never updates. If i debug the asp.net page the watch var shows the datetime in US format (I.e "09/24/07 12:58"), if this is true then this would explain why when it is passed to the stored proc nothing gets updated, as there would not be a date match.
can anyone see any silly mistakes i'm doing here ????

I am trying to write a stored procedure that updates a value in a table based on the sort order. For example, my table has a field "OfferAmount". When this field is updated, I need to resort the records and update the "CurrRank" field with values 1 through whatever. As per my question marks below, I am not sure how to do this.
Update CurrRank = ??? from tblAppKitOffers
where appkitid = 3 AND (OfferStatusCode = 'O' OR OfferStatusCODE = 'D')
ORDER BY tblAppKitOffers.OfferAmount Desc
All help is greatly appreciated.

Hi,
DONT KNOW IF IT IS POSSIBLE.. PLEASE SUGGEST.
Currently working on a upload module where in the data from excel file is imported to the destination tables. Data in the excel sheet comes in phases. All excel sheet columns data don't come at first shot. The excel sheet's data is dumped into temporary tables which inturn is looped using cursor's and gets finally updated to the actual tables.
Now, the problem I am facing is how do I update columns of the actual table with the data (i.e NON NULL values) available in the temporary table without tampering the data allready present in actual table.
Ideally what required is, update the actual table column values with the corresponding columns of temporary table ONLY for Non NUll column values of temporary table.
Temporary and Destination tables have 85 columns each. I don't want to write 85 update queries.
The scenario which I am facing is given below with 2 columns as an example.
1. Table 1 :- tbl_source (Temporary Table) has two columns src_Col1 & src_Col2
2. Table 2 :- tbl_destination (Actual Table) has two columns dest_Col1 & des_Col2
Scenario -1
---------------
tbl_Source Sample Data (after excel import to the temporary table)
------------------------
src_Col1 src_Col2
------------------
50 NULL
tbl_Destination Sample Data
------------------------
dest_Col1 dest_Col2
------------------
50 NULL
Scenario -2
---------------
tbl_Source Sample Data
------------------------
src_Col1 src_Col2
------------------
NULL 100
tbl_Destination Sample Data
------------------------
dest_Col1 dest_Col2
------------------
50 100
One update query which handles both scenarios.
Thanking you in anticipation.
Regards

Hello All
I am trying to figure out if what i am attempting to do is possible and whether or not my approach is wrong to begin with.
I am trying to build a custom report for our accounting system which is Traverse from Open systems. This is what i have done in the stored procedure thus far
SET QUOTED_IDENTIFIER ON
GO
SET ANSI_NULLS ON
GO
ALTER PROCEDURE rptArFLSalesByCustItemized_sp
@custId pCustID,
@dateFrom datetime,
@dateThru datetime,
@itemIdFrom pItemId,
@itemIdThru pItemId
as
set nocount on
-- define some variables for previous year
declare @LYqty int, @LyAmt money, @LYfrom datetime, @LYthru datetime
-- set defaults
SET @itemIdFrom=ISNULL(@itemIdFrom,(SELECT MIN(itemId) FROM tblInItem))
SET @itemIdThru=ISNULL(@itemIdThru,(SELECT MAX(itemId) FROM tblInItem))
SET @LYfrom=DATEADD(YEAR,-1,@dateFrom)
SET @LYthru=DATEADD(YEAR, -1, @dateThru)
-- create small temp table to hold customer info
Create Table #tmpArCustInfo
(
custId pCustID,
custName VARCHAR (30),
)
-- populate customer temp table with info
Insert into #tmpArCustInfo
select custId, custName
from tblArCust
WHERE custId = @custId
-- create a temp table to hold the Data for each Item
Create Table #tmpArSalesItemized
(
itemId pItemId,
productLine VARCHAR (12),
pLineDesc VARCHAR (35),
descr VARCHAR (35),
LYQtySold int,
LYTDQtySold int,
QtySold int,
LYTDsales money,
totalSales money,
LastInvDate datetime,
)
-- populate the temp table with all of the inventory items
insert into #tmpArSalesItemized
select ii.itemId, ii.productLine, ip.Descr, ii.Descr, 0,0,0,0,0, NULL
from tblInItem ii, tblInProductLine ip
where ip.productLine = ii.productLine
AND ii.itemId BETWEEN @itemIdFrom AND @itemIdThru
-- update table with this years quantities
update #tmpArSalesItemized
SET QtySold = (select SUM(QtyOrdSell) from tblArHistDetail hd
where TransId IN (select TransId from tblArHistHeader where custId = @custId)
AND orderDate IN (select OrderDate from tblArHistHeader where OrderDate BETWEEN @dateFrom AND @dateThru)
AND hd.partId BETWEEN @itemIdFrom AND @itemIdThru
GROUP BY hd.partId
)
-- Return the temp tables results
select * from #tmpArSalesItemized, #tmpArCustInfo
drop table #tmpArSalesItemized, #tmpArCustInfo
return
GO
SET QUOTED_IDENTIFIER OFF
GO
SET ANSI_NULLS ON
GO
My problems begin where i want to start updating all of the Qty's of the QtySold field. I have managed to get it to write the same sum in every field but i cannot figure out how to update each row based on the sum of the qty found for that item in the tblArHistDetails table, trouble is too that there is no reference to the custId in that table either. The custId resides in tblArHistHeader and is linked to the details table via the TransId column. So really i need to update many rows based on criteria from 2 other tables.
Can anyone please help? I dont have a clue how to make this work, and most of what i have learned about sql thus far has been from opening other stored procs etc in the accounting system and just reading to see how the developers have done things.
Thanks
Jamie

I am trying to update records based on the results of a query with a subquery.
The result set being produced shows the record of an item number. This result produces the correct ItemNo which I need to update. The field I am looking to update is an integer named Block.
When I run the update statement all records are updated and not the result set when I run the query by itself.
Below you will find the code I am running:
create table #Items
(
ItemNovarchar (50),
SearchNo varchar (50),
Historical int,
Blocked int
[Code] ....
Below is the code I am using in an attempt to update the block column but it updates all records and not the ones which I need to have the Blocked field set to 1.
Update #items set Blocked = 1
Where Exists
(
SELECT ItemNo=MAX(CASE rn WHEN 1 THEN ItemNo END)
--,SearchNo
--,COUNT(*)
[Code] ...
Why is the update changing each record? How can I change the update to choose the correct records?

CREATE TABLE EDI_data_proc_log(
ID int IDENTITY(1,1),
comment VARCHAR(3000),
time_recorded DATETIME DEFAULT GETDATE(),
run_by varchar(100),
duration int );
When a record is inserted I like the duration column to be computed.This should happen only after the first record to the table has gotten inserted.You might say a trigger would be the best.. Ok then, show me the syntax.
Or I am thinking can we write a user defined function that will compute the value for the duration column.
--By default, I would like to update the duration column as follows:
--It should record the number of seconds between the last insertion ( You can get that time from the time_recorded column from the previous record and the current time can be obtained from the getdate() function )

I have a report that uses different datasets based on the year selected by a user.
I have a year_id parameter that sets a report variable named dataset_chosen. I have varified that these are working correctly together.
I have attempted populating table cell data to display from the chosen dataset. As yet to no avail.
How could I display data from the dataset a user selects via the year_id options?

Here is a requirement. Need to update the columns in the tables with the latest values available in CSV.
The file is based on department so the list of tables which is under this department all the corresponding tables needs to updated.
The CSV file which is dynamic in nature the number of columns changes it has header of the columns that needs to be updated.
The destination tables are listed under department table for each department. So I have to update the columns in the tables with the values in csv.

I have an application that needs to create invoices on a daily basis to multiple clients based on orders shipped that day. This is easy to do on the front-end. But how can I do this on the back end in SQL Server.
I want to sort orders by Client ID and put all orders belonging to one customer on one invoice. When customer id changes, I change the Invoice ID. Is this possible in SQL?

Hi there,
I need to create a stored procedure that I can pass in an arbitrarily long list of record IDs and have an SQL statement executed for each one.
For instance, I want to be able to pass in 1, 2, 5, 78, 100, 216 and have it automatically execute:
UPDATE table SET value='blah' WHERE id=1; UPDATE table SET value='blah' WHERE id=2; UPDATE table SET value='blah' WHERE id=5; UPDATE table SET value='blah' WHERE id=78; UPDATE table SET value='blah' WHERE id=100; UPDATE table SET value='blah' WHERE id=216
Can anyone please show me how I would structure a stored procedure like this? Specifically, how would I pass the list of IDs in as a parameter, and how would I iterate through them.
Much appreciated!!

A Stored Procedure inserts a record in a base table. I want to add n records (n=1 to 5) into a related table. Another SP (tdAuthorityInsert) is already set up to insert one record into the related table.
So, two questions
1. What is the form of an iterative loop in a Stored Procedure?
2. How do you call a Stored Procedure from inside another?
Thanks, td

I am having a mental fart...
I have two tables:
DECLARE @store_options TABLE(store_option_id INT IDENTITY(1,1), store_id INT)
DECLARE @vendor_options TABLE(vendor_option_id INT IDENTITY(1,1), store_option_id INT, item_id INT, vendor_id INT, price NUMERIC(18,4))
I populate the first table with a litst of stores that offer all desired items.
I populate the second table with a list of vendors, the item is, and cost avaiable at each of the stores in the first table.
What I would like is to output all possible the store and vendor combos ordered by combined price.
So, for instance, I have 3 products, A B and C. Store X has A and B by vendor G, and A B and C by vendor H. I want the output to have all iterations of (Store, Product, Vendor, Price) grouped in order of total price. So...
X A G
X B G
X C H
X A G
X B H
X C H
X A H
X B G
X C H
X A H
X B H
X C H
ordered by each group's combined price.
For some reason, I can't get this straight in my head. Must need more coffee.

How can I force a Next Iteration in a ForEach Loop container?
I am looping through a folder(ForEach Loop Container) looking for a specific File Name ( Child 'Script Task') to evaluate name).
If the current file is not the File Name I need, get the next file, other wise drop down to a Exec Proc task.
Is it possible to force "Next Interation' on the parent container?

I have a synchronous script component and have added 5 fields to the output (field1, field2... field5). Can I iterate those fields?
In sudo language, I'd like to do:
Code Snippet
Public Overrides Sub Input0_ProcessInputRow(ByVal Row As Input0Buffer)
dim i as integer = 1
while i < 6
row.field[i] = "somevalue: " + i.ToString
end while

Somehow, I'd like to be able to do that without specifying each field individually:
row.field1 = "somevalue: " + "1"
row.field2 = "somevalue: " + "2"

Hey guys, wonder if you could help.
I have a flow which is within a foreach loop. The first box in the flow is a scrip component which makes some check in a database.
Is there a way to say, inside that script component: 'stop the flow here, don't bother going onto the next box, and go on to the next iteration'?
thanks!

I 've have a stored procedure that compares fields across databases.In order to do so it requires 2 values it acquires from 2 tables. Thesearch is based on the ID of the data owner and a subject:proc_evaluate_results @StudentId = '222222', Course = 'PSY101'In order to obtain those values I run a cursor accross my records andSELECT THEM INTO 2 @variables, which then replace 222222 and PSY101with dynamic values eg.--define a cursor etc.etc.WHILE @@cursor_fetch = 0BEGIN--do the cursor call INTO @varsEXEC proc_evaluate_results @StudentId = @studentID, @Course =@CourseCodeENDNow,the vars are being passed to the stored procedure and executed OK,but the cursor gets stuck on the last record and continues to evaluateit until stopped manually.If I comment out the EXEC and replace it with eg. PRINT @Course + ' |' + @CourseCode it runs fine, exiting after the last record.ThanksR>

Hi,
I'm very new to stored procedures and I've been searching on google to find a way to custom page my results using SQL Server 2005. I'm trying to use Row_Number() and a CTE to keep things efficient and scaleable but I keep getting an error next to my UPDATE statement.
I get the following error: "[Microsoft][ODBC SQL Server Driver][SQL Server]Incorrect syntax near the keyword 'UPDATE'."
The sproc works without the UPDATE statement. Does anyone know where I need to put the UPDATE statement to update the "searched" field for each record selected?
CREATE PROCEDURE [zk_update_request_england](@property_type tinyint,@market_status tinyint,@price int,@bedrooms tinyint,@search_location varchar(30),@search_district varchar(30),@PageSize int,@PageIndex int)
AS
BEGIN
WITH SearchResults AS(
UPDATE dbo.zk_request_england SET searched = searched + 1 WHERE property_type = @property_type AND market_status = @market_status AND bedrooms = @bedrooms AND search_location = @search_location AND search_district = @search_district AND min_price <= @price AND max_price >= @price
SELECT user_id, min_price, max_price, property_description, searched, ROW_NUMBER() OVER (ORDER BY max_price DESC) AS RowNumber FROM dbo.zk_request_england WHERE property_type = @property_type AND market_status = @market_status AND bedrooms = @bedrooms AND search_location = @search_location AND search_district = @search_district AND min_price <= @price AND max_price >= @price
)
SELECT user_id, min_price, max_price, property_description FROM SearchResults WHERE RowNumber BETWEEN (@PageIndex - 1) * @PageSize + 1 and @PageIndex*@PageSize
END

Hey all, I'm having an interesting problem, but also keep in mind I am certainly a newbie with DB's and SQL but here's what I got:
I'm making an application that creates quotes for our customers. I want to create a Quote Number that is based on the largest of the last number in the DB but only based on that company. For example:
CoID QuoteNum
123 1
123 2
666 1
123 3
666 2
666 3
so if I created a new quote for CoID: 666, the QuoteNum would be 4. Easy enough. But the problem arises when I create a new quote for a NEW COMPANY, one who's CoID is not already present in the DB. So what I have so far is this:
SELECT QuoteNum FROM Quote
WHERE QuoteNum = (SELECT MAX(QuoteNum) FROM Quote
WHERE CoID='222')
but since 222 does not yet exist I get an error: "Either BOF or EOF is True, or the current record has been deleted. Requested operation requires a current record."
So how do I tell the DB to ignore that error and perform another task should it arise? Any help would greatly be appreciated. THANKS!

In Oracle I would use:
select * from foo where TIMESTAMP >= trunc(sysdate - 1) + 8/24 AND TIMESTAMP < trunc(sysdate) + 8/24.
This would start at 8am yesterday and end at 7:59am today.
How would I do this with T-SQL?
