How To Get Prices From Table Where Date Not Exists
Feb 17, 2013
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...
-- Create Test Table (not sure if dates USA or UK format on your machine...
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.
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";
This is on Sybase but I'm guessing that the same situation would happen on SQL Server. (Please confirm if you know).
I'm looking at these new databases and I'm seeing code similar to this all over the place:
if not exists (select 1 from dbo.t1 where f1 = @p1) begin select @errno = @errno | 1 end
There's a unique clustered in dex on t1.f1.
The execution plan shows this for this statement:
FROM TABLE dbo.t1 EXISTS TABLE : nested iteration. Table Scan. Forward scan. Positioning at start of table.
It's not using my index!!!!!
It seems to be the case with EXISTS statements. Can anybody confirm?
I also hinted to use the index but it still didn't use it.
If the existence check really doesn't use the index, what's a good code alternative to this check?
I did this and it's working great but I wonder if there's a better alternative. I don't really like doing the SET ROWCOUNT 1 and then SET ROWCOUNT 0 thing. SELECT TOP 1 won't work on Sybase, :-(.
SET ROWCOUNT 1 SELECT @cnt = (SELECT 1 FROM dbo.t1 (index ix01) WHERE f1 = @p1 ) SET ROWCOUNT 0
This is my query, from my nonono table I need to return the most recent date from attempted (column name) Â How could I modify this to do such
Select * FROM [nonono] td WHERE (NOT EXISTS (SELECT [First], [second] FROM [yesyesyes] AS d WHERE ([First] = td.[First]) AND ([second] = td.[second]) AND ([Worksite] = td.[Worksite])))

Now, suppose a employee applies leave on 26/01/2015 to 26/01/2015 then it should not insert into table and return a value "Not updated"
How to handle the scenario if a employee applies leave between the range 23/01/2015 to 27/01/2015, since 26/01/2015 is a holiday in between. how the data can still be inserted excluding 26/01/2015
Can we exclude a non-working day or a sunday.
Leavedetails table to insert leaves applied by employee is as follows
LeaveDetailID int LeaveTypeId int FromDate datetime EndDate datetime Remarks nvarchar

I need to find out if a Transaction ID exists in Table A that does not exist in Table B. Â If that is the case, then I need to insert into Table B all of the Transaction IDs and Descriptions that are not already in. Seems to me this would involve If Not Exists and then an insert into Table B. Â This would work easily if there were only one row. Â What is the best way to handle it if there are a bunch of rows? Â Should there be some type of looping?
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)?
I would like to return the nearest date of Table B in my table like for
ID W001 in table B should return ID A002 CreatedDatetime: 2014-06-03 20:05:48.000 ID W002 in table B should return ID A004 CreatedDatetime: 2014-06-04 01:05:48.000
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.
select product.type, pc.price as pcprice, laptop.price lapprice, pc.model as pcmod, laptop.model as lapmod from product join pc on product.model=pc.model join laptop on laptop.model=product.model where maker = 'B'
the syntex runs but its not displaying any results + I know that I have some extra columns there but its for some thing else I was trying

HI, having a problem with a data loading from 2005 to 2000. Im using export & import wizard. But the problem comes when the user drops a table on 2005. Anyway to check if table exista then use the E&I to load the data. I cant use the BCP as xp_shellcmd is disable.
Hi all,I am in the process of creating a page that checks to see if a particular user exists in the database and if it does then send to welcome.aspx if not then accessdenied.aspx. The userid is requested from the query string.I have done some research and cannot find anything directly related, I have tried to add bits of code into what i think is the right place but I dont think what i am doing is correct. Can someone help and show me where my code is going wrong? Also is there a better/more efficient way to do what I am doing?Thanks in advance. default.aspx.csusing System;using System.Data;using System.Data.SqlClient;using System.Configuration;using System.Web;using System.Web.Security;using System.Web.UI;using System.Web.UI.WebControls;using System.Web.UI.WebControls.WebParts;using System.Web.UI.HtmlControls;public partial class _Default : System.Web.UI.Page{ protected void Page_Load(object sender, EventArgs e) { string UserID = Request.QueryString["uid"]; //string TransferPage; if (UserID != null) { //initiate connection to db SqlConnection objConnect = new SqlConnection(System.Configuration.ConfigurationManager.ConnectionStrings["MyConnection"].ConnectionString); string sql = "SELECT COUNT(*) FROM members WHERE UserID = '" + UserID + "'"; SqlCommand query = new SqlCommand(cmd, test); int count = (int)query.ExecuteScalar(); int aantal = -1; // some default value if can't insert record if (count == 0) // no existing record for username { Server.Transfer("accessdenied.aspx"); } else { Session["UID"] = UserID; Server.Transfer("welcome.aspx"); } } }}
i am using vb.net and ms sql server 2005 express.....what is the syntax for dropping a table if existsi have used this but it says incorrect syntax near if Dim cmda As New SqlCommand("drop table " + test + " if exists", New SqlConnection(strdb)) cmda.Connection.Open() cmda.ExecuteNonQuery() cmda.Connection.Close()any solutions???? plz only answer in vb.net and sql server express
What is the best way to programmatically determine if a temp table exists? In 6.5, I would use
IF EXISTS(SELECT * from tempdb..sysobjects where id = object_id('tempdb..#MyTable') and type = 'U')
But now that it is strongly discouraged to code against system tables, how could I re-write this statement?
The proper way to check the existence of a table would be:
IF OBJECTPROPERTY(object_id('tablename'), 'IsTable') = 1
However, to get this to run for a temp table, I think you'd have to change the database context to tempdb and then back to your database. That doesn't seem efficient.
I could use
IF object_id('tempdb..#MyTable') IS NOT NULL
But that's not guarenteeing that it's a table, right?
How do I find out if a temporary table named '##test' exists? I have a stored procedure that creates this table and if it exists another stored procedure should do one thing, if it does not exist I want the SP to do something else. Any help as to how I can determine if this table exists at the current time would be greatly appreciated.
This my first time using the link server to read the files directly from within SQL2005, so issues the following link:-
EXEC sp_addlinkedserver @server = N'MYVFPSERVER', -- Your linked server name here @srvproduct=N'Visual FoxPro 9', -- can be anything @provider=N'VFPOLEDB', @datasrc=N'"C:PROGRAM FILESMICROSOFT VISUAL FOXPRO 9Samplesdata estdata.dbc"'
After that i can open query and do the import issues, but how can check if the table exists before issues the query.
Hi,I am trying to create a script that deletes transaction tables and leavesmaster data like customer, vendors, inventory items, etc. How can I useTRUNCATE TABLE with an Exists? My problem is I have 200+ tables, if Isimply use a list like:truncate table01truncate table02truncate table03....I get errors if the table does not exist and have to manually run thetruncate statements. Some tables may not exist if that part of the app isnever used. I'm trying to make a list of all tables that could existwithout it erroring out 50+ times.Thanks in advance.
What’s the easiest way to check if a single value exists in a table column? I’m building a simple login page, and I want to get the username and check if it exists in my Users table. Here’s my SQL: SELECT UserID FROM UsersWHERE UserID = "admin" Could someone give me code to check for “admin” in my UserID column? Here’s some code I tried, using my SqlDataSource, but it returns an error “Could not load type 'System.Data.OleDb'” protected void Button1_Click(object sender, EventArgs e) { // Retreive the results from the SqlDataSource as a DataReader OleDbDataReader reader = (OleDbDataReader) SqlDataSource1.Select(DataSourceSelectArguments.Empty); // Read in the value if (reader.Read()) { } // Close the reader reader.Close(); } I don’t have to use the SqlDataSource, but originally thought it might be easier. I know how to use SqlDataSource to fill a whole GridView but this is different.
Basically, i am still relatively new to ASP.net and SQL. And i have the following query. I have a skills table to which the user enters their skills using the following fields: Skillcatagory, SKill, Current Level, Target Level, target date and comments and the serial of the user. I need to check via our staff table, which people have had a skill entered for them. And then produce a report on who has not had a skill entered for them. This table has a serial of the user column aswell which is unique. If there is more information that i can give you to assist me, please ask me. You help would be greatly appreciated.
I need to do some processing but only if a specific table 'table1' exists in the SQL Server database. How can I check if this 'table1' exists using either ADO.Net code or SQL Server query?
I've got two tables, one containing a list of company names(approx 10,000 records), the other containing a list of company employees (approx 30,000 records) joined by the CompanyID column.
I have a third table (approx 700 records) containing new employees to be added to the employee table. Each record in this table has the employees details plus the name of their company.
I want to write a query that will check each row in the third table to see if a) the employee exists in the Employees table b) the company exists in the Companies table and c) the employee is listed under the correct company
The query should also handle any combination of the above. So if the company doesn't exist but the employee does, create the company on the companies table and update the appropriate record on the employees table with the new CompanyID etc. etc.
Oh, forgot to mention. The company names in the third table won't be exactly the same as the ones in the Company table so will need to use CharIndex.
