I have a company that sells fruit and vegetables to the catering industry. I take orders in the evening for the next day, and buy my fruit and vegetables from wholesale market to deliver to my customers on the next day. I have sage simply accounting. I have to enter invoices day before I print them, so I can get a list of items i should buy next day (and also sort them into different routes) My question is, is there a way to update all the prices on the active invoices (i.e. not printed or posted) for the previous day, after I enter new prices for the fruit and vegetables??? I need this as at the moment I hava to go into individual invoices and enter the products and quantities again.
SELECT BillDate, (SELECT SUM( Price) FROM Table1 ) AS SumDaylyPrice FROM Table1 WHERE BillDate BETWEEN (SELECT Min(BillDate) FROM Table1) AND (SELECT Max(BillDate) FROM Table1) GROUP BY BillDate
but this doesn’t work- summing everityng
I don’t know how to indicate in first row of query SELECT BillDate, (SELECT SUM( Price) FROM Table1 WHERE DATE = ????) AS SumPrice a WHERE clause for every day separately.
I have 2 test tables one for stock and one for prices.
I need to select all the rows from Stock but also the price on the stock but the price table doesn't always have the date, so I can not do stock date = price date.
What it needs to do is if the Stoc Date isn't in the price table use the price before... this would also have to be able to run on my rows...

I have a SQL2005 db for tracking the prices of products at multiple retailers. The basic structure is, 'products' table lists individual products, 'retailer_products' table lists current prices of the products at multiple retailers, and 'price_history' table records when the price of a product changes at any retailer. The prices are checked from each retailer daily, but a row is added to the 'price_history' only when the price at the retailer changes.
I have the following query to retrieve the price history of a given product at multiple retailers:
SELECT price_history.datetimeofchange, retailer.name, price_history.price FROM product, retailer, retailer_product, price_history WHERE product.id = 'b486ed47-4de4-417d-b77b-89819bc728cd' AND retailer_product.retailerid = retailer.id AND retailer_product.associatedproductid = product.id AND price_history.retailer_productid = retailer_product.id
This gives the following results:
2008-03-08 Example Retailer 22.3 2008-03-28 Example Retailer 11.8 2008-03-30 Example Retailer 22.1 2008-04-01 Example Retailer 11.43 2008-04-03 Example Retailer 11.4
The question(s) I have are how can I:
1 - Get the price of a product at a given retailer at a given date/time For example, get the price of the product at Retailer 2 on 03/28/2008. Table only contains data for Retailer 1 for this date, the behaviour I want is when there is no data available for the query to find the last data at which there was data from that retailer, and use the price from that point - i.e. so for this example the query should result in 2.3 as the price, given that was the last recorded price change from that retailer (03/08/2008).
2 - Get the average price of a product at a given retailer at a given date/time In this case we would need to perform (1) across all retailers, then average the results
I would like to use analysis services to analyze stock prices.
I want to find conditional probabilities: P (YpriceChg >= 10% s.t. Ydate between A and B| X Price Chg >= 20%)?
€¦ Like given a price change of X percent or greater, predict the probability of a price change of Y percent or greater, within a specified time window (like 2 days, 3 months etc.).
I also want to add a support filter, like:
N > 30 cases (i.e., there have been at least 10 instances of a 10% or greater price change, for the chosen time window)
I have a database of prices, monthly, daily, etc. I also have a number of cols that compute statistics such as pChg1M, pChg-1M, vChg1d. Like price chg 1 month forward, price change 1 month backward, volumeChg1d forward. Ideally, I would like to minimize the column flags necessary for the experiment. Can you offer some hints, as far as setting up appropriate columns/flags and choosing a algorithm (maybe decision trees, association rules, or NB)?
Hi,I would like to change my select to generate table that will resultsThat will haveService, Room, Season A, Season BWhere season names are saved in database and in their colums I would like to have pricing for rooms.How can I accomplish this - I dont know how to clearly explain - hope SQL will help: String selectCommandBookings = "SELECT dbo.Service.Name AS Service, dbo.Room.Name AS Room, dbo.Season.Name AS Season, dbo.HSRSeason.Price"; selectCommandBookings += " FROM dbo.Season INNER JOIN"; selectCommandBookings += " dbo.HSRSeason ON dbo.Season.SeasonID = dbo.HSRSeason.SeasonID INNER JOIN"; selectCommandBookings += " dbo.HSR ON dbo.HSRSeason.HSRID = dbo.HSR.HSRID INNER JOIN"; selectCommandBookings += " dbo.Room ON dbo.HSR.RoomID = dbo.Room.RoomID INNER JOIN"; selectCommandBookings += " dbo.Service ON dbo.HSR.ServiceID = dbo.Service.ServiceID"; selectCommandBookings += " WHERE (dbo.HSR.HotelID = '" + hotelID + "')"; selectCommandBookings += " ORDER BY dbo.Service.Name, dbo.Room.Name, dbo.HSRSeason.Price";
Assume you have a table called Tick with 2 columns ( tickId bigint IDENTITY(1,1) , price int -- usually money data type, making it int for simplicity )
I am tasked with creating bars that are 10 units long.
Now the catch is I'm not looking for the tickId where price is >= t1(price) + 10 where t1(price) is the price for the first row where tickId = 1. (it could also be where price <= t1(price) - 10)
Code: DECLARE @tickDiff int SET @tickDiff = 10 DECLARE @r1TickId bigint
[Code].....
This seems to work but it is taking multiple minutes to run for about 50k rows of data (which I created off of the 24 million row table I have just looking at data from today). So it takes ~5 minutes to create the first bar which is not acceptible.
If my logic above seems acceptable are there any indexes you could recommend. Database engine tuning advisor didn't find any.

I am working on a stock price analysis project. Stock prices are stored in SQL Server as tick by tick data (that means in a high frequency) and need to be grouped by minutes in order to display them as as high, low, open and close prices in a candlestick or similar chart.
The fields in the table are:
Time (for every stock price tick) Price (stock price) Symbol (of the stock)
I am trying to copy an entire column of pricing into another price column.
Basically we use item_prc_1, item_prc_2, item_prc_3 to set different pricing structures. There are 52000+ SKUs in this table and I want to copy all item_prc_1 data to item_prc_2.
I also want to be able to constrain the data copied based on item_cat which contains the items category marker.

What settings or whatever would cause this to take so much longer from the linked server?
Edit: Note) Other queries from the linked server do not have this behavior. From the stored procedure where we have examined how long each query/update takes... this particular query is the culprit for the time eating. I thought it was to do specefically with this table. However as stated when a query window is opened directly onto that server the update takes no time at all.
2nd Edit: Could it be to do with this linked server setting? Collation Compatible right now it is set to false? I also asked this question in a message below, but figured I should put it up here.
I am hoping someone can shed light on this odd behavior I am seeing running a simple UPDATE statement on a table in SQL Server 2000. I have 2 tables - call them Table1 and Table2 for now (among many) that need to have certain columns updated as part of a single transaction process. Each of the tables has many columns. I have purposely limited the target column for updating to only ONE of the columns in trying to isolate the issue. In one case the UPDATE runs fine against Table1... at runtime in code and as a manual query when run in QueryAnalyzer or in the Query window of SSManagementStudio - either way it works fine. However, when I run the UPDATE statement against Table2 - at runtime I get rowsaffected = 0 which of course forces the code to throw an Exception (logically). When I take out the SQL stmt and run it manually in Query Analyzer, it runs BUT this is the output seen in the results pane... (0 row(s) affected) (1 row(s) affected) How does on get 2 answers for one query like this...I have never seen such behavior and it is a real frustration ... makes no sense. There is only ONE row in the table that contains the key field passed in and it is the same key field value on the other table Table1 where the SQL returns only ONE message (the one you expect) (1 row(s) affected) If anyone has any ideas where to look next, I'd appreciate it. Thanks
Hi SQL fans,I realized that I often encounter the same situation in a relationdatabase context, where I really don't know what to do. Here is anexample, where I have 2 tables as follow:__________________________________________ | PortfolioTitle|| Portfolio |+----------------------------------------++-----------------------------+ | tfolio_id (int)|| folio_id (int) |<<-PK----FK--| tfolio_idfolio (int)|| folio_name (varchar) | | tfolio_idtitle (int)|--FK----PK->>[ Titles]+-----------------------------+ | tfolio_weight(decimal(6,5)) |+-----------------------------------------+Note that I also have a "Titles" tables (hence the tfolio_idtitlelink).My problem is : When I update a portfolio, I must update all theassociated titles in it. That means that titles can be either removedfrom the portfolio (a folio does not support the title anymore), addedto it (a new title is supported by the folio) or simply updated (atitle stays in the portfolio, but has its weight changed)For example, if the portfolio #2 would contain :[ PortfolioTitle ]id | idFolio | idTitre | poids1 2 1 102 2 2 203 2 3 30and I must update the PortfolioTitle based on these values :idFolio | idTitre | poids2 2 202 3 352 4 40then I should1 ) remove the title #1 from the folio by deleting its entry in thePortfolioTitle table2 ) update the title #2 (weight from 30 to 35)3 ) add the title #4 to the folioFor now, the only way I've found to do this is delete all the entriesof the related folio (e.g.: DELETE TitrePortefeuille WHERE idFolio =2), and then insert new values for each entry based on the new givenvalues.Is there a way to better manage this by detecting which value has to beinserted/updated/deleted?And this applies to many situation :(If you need other examples, I can give you.thanks a lot!ibiza

If I have a table with 1 or more Nullable fields and I want to make sure that when an INSERT or UPDATE occurs and one or more of these fields are left to NULL either explicitly or implicitly is there I can set these to non-null values without interfering with the INSERT or UPDATE in as far as the other fields in the table?
EXAMPLE:
CREATE TABLE dbo.MYTABLE( ID NUMERIC(18,0) IDENTITY(1,1) NOT NULL, FirstName VARCHAR(50) NULL, LastName VARCHAR(50) NULL,
[Code] ....
If an INSERT looks like any of the following what can I do to change the NULL being assigned to DateAdded to a real date, preferable the value of GetDate() at the time of the insert? I've heard of INSTEAD of Triggers but I'm not trying tto over rise the entire INSERT or update just the on (maybe 2) fields that are being left as null or explicitly set to null. The same would apply for any UPDATE where DateModified is not specified or explicitly set to NULL. I would want to change it so that DateModified is not null on any UPDATE.
INSERT INTO dbo.MYTABLE( FirstName, LastName, DateAdded) VALUES('John','Smith',NULL)
INSERT INTO dbo.MYTABLE( FirstName, LastName) VALUES('John','Smith')
INSERT INTO dbo.MYTABLE( FirstName, LastName, DateAdded) SELECT FirstName, LastName, NULL FROM MYOTHERTABLE

It appears to update only the first qualifying row. The trace shows a row count of one when there are multiple qualifying rows in the table. This problem does not exist in JDBC 2000.
I'm having a strange problem that I can't figure out. I have an SQL stored procedure that updates a small database table. When testing the Stored Procedure from the Server Explorer, it works fine. However, when I run the C# code that's supposed to use it, the data doesn't get saved. The C# code seems to run correctly and the parameters that are passed to the SP seem to be okay. No exceptions are thrown. The C# code: SqlConnection conn = new SqlConnection(ConfigurationManager.ConnectionStrings["touristsConnectionString"].ConnectionString); SqlCommand cmd = new SqlCommand("fort_SaveRedirectURL", conn); cmd.CommandType = CommandType.StoredProcedure; Label accomIdLabel = (Label)DetailsView1.FindControl("lblID"); int accomId = Convert.ToInt32(accomIdLabel.Text); cmd.Parameters.Add("@accomId", SqlDbType.Int).Value = accomId; cmd.Parameters.Add("@path", SqlDbType.VarChar, 250).Value = GeneratePath(); try { conn.Open(); cmd.ExecuteNonQuery(); } catch(Exception ex) { throw ex; } finally { conn.Close(); } The Stored Procedure: ALTER PROCEDURE developers.fort_SaveRedirectURL ( @accomId int, @path varchar(250) ) AS DECLARE @enabled bit, @oldpath varchar(250)
/* Ensure that the accommodation has been enabled */ SELECT @enabled = enabled FROM Experimental_Accommodation WHERE Experimental_Accommodation.id = @accomId
IF (@enabled = 1) BEGIN /* Now check if a path already exists */ SELECT @oldpath = oldpath FROM Experimental_Adpages_Redirect WHERE Experimental_Adpages_Redirect.accom_id = @accomId
IF @oldpath IS NULL BEGIN /* If Path already exists then we should keep the existing URL */ /* Otherwise, we need to insert a new one */ INSERT INTO Experimental_Adpages_Redirect (oldpath, accom_id) VALUES (@path,@accomId) END END RETURN
I'm new to this forum. This 'problem' has occured many times, but I've always found a way around it. I have pages with datagrids, in which a user can edit a certain fields and then update the tables with new data. Lets say when a user edit a Name field and a money field. If he/she left those two fields blank, the table is automatically updated with a <null> (for the name field) and a 0 (for the money field.) Both these columns were set up to allow Null values. Anyone has an idea why they were updated that way? And is there like a standard on how the data types are updated if a field is left blank? Thank you very much.
I do realize that his could be posted in a few spots but I think the answer is in the SQL. I have a ASP.NET page, with a SqlDataSource, Text Box and Calendar Controls. I have the textbox and calendar controls eval'ed to the same sql data source DateTime Field. The text box is formatted eval to small time and the calendars eval has no formatting. ex: <asp:TextBox ID="START_TIME" Text='<%# Eval("EVENT_START","{0:t}") %>' runat=server Width=200></asp:TextBox> I want to merge the two controls; one has the date the other has the time when I update the pages data to the SqlDataSource field EVENT_START. I've tried a couple of methods, but I would like some other opinions. As Sql server only supports date and time together I am storing the two together. I could merge the two together in the code behind on the update button's event handler or merge the two during the update query using parameters. Not that I could get an illegal date for the calendar control, but I could get garbage from the textfield time. So I still would have to do validation on the text field before the SQL server could do the update. There's a few ways to go about this, so I was wondering if anyone else has figured out an elegant way to handle it. wbochar
I want to update two tables in one page. So I created two FormView bound on two SqlDataSource controls, and I create a Update button on the bottom of page. And I writen some codes as below: btnUpate_Click(object sender, EventArgs e){ sqlDataSource1.Update(); sqlDateSource2.Update();} But, the records haven't updated. In SqlDataSource2_Updating() function, I found all the parameters is null. So, how to modify my code to do it.
I want to retrieve the last update time of database. Whenever any update or delete or insert happend to my database i want to store and retrieve that time.
I know one way is that i have to make a table that will store the datetime field and system trigger / trigger that can update this field record whenever any update insert or deletion occur in database.
But i don't know exactly how to do the coding for this?
I have a table where table row gets updated multiple times(each column will be filled) based on telephone call in data.  Initially, I have implemented after insert trigger on ROW level thinking that the whole row is inserted into table will all column values at a time. But the issue is all columns are values are not filled at once, but observed that while telephone call in data, there are multiple updates to the row (i.e multiple updates in the sense - column data in row is updated step by step),
I thought to implement after update trigger , but when it comes to the performance will be decreased for each and every hit while row update.
I need to implement after update trigger that should be fired on column level instead of Row level to improve the performance?
I'm writing a fairly involved stored procedure. In this Stored Procedure, I have an update statement, followed by a select statement. The results of the select statement should be effected by the previous update statement, but its not. When the stored procedure is finish, the update statement seemed to have worked though, so it is working.
I suspect I need something, like a GO statement, but that doesnt seem to work for a stored procedure. Can anyone offer some assistance?
Hi! Select gets all records that contains illegal chars... Ok, to replace '[' { and some other chars I will make AND '% .. %' and place other intervals, that is not the problem.The problem is: How to replace not allowed chars ( ! @ # $ % ^ & * ( ) etc. ) with '_' ?I have seen that there is a function REPLACE, but can't figure out how to use it. 1 SELECT user_username 2 FROM users 3 WHERE user_username LIKE '%[!-)]%';

I'm looking for a query that can "batch" update one table from another. For example, say there are fields on both tables like this: KeyField Value1 Value2 Value3 The two tables will match on "KeyField". I would like to write one SQL query that will update the "Value" fields in Table1 with the data from Table2 when there is a match.
