Get A Max Value From One Table Base On Date From Another.
Jul 20, 2006
I have a problem where I need to join multiple tables. Part of the query needs me to make the following relationship in a join.
Say I have a table with items, prices, and dates.
PriceTable
ITEM PRICE DATE
A 1.00 5/5/2000
B 3.00 1/1/2000
A 2.50 6/5/2004
....
This table represents an items price from the date on. So Item 'A' costed 1.00 from 5/5/2000 through 6/5/2004, then it costed 2.50 from that day on.
Now say I have a table of transactions with items, amount bought, and dates.
TransactionTable
ITEM AMOUNT DATE
A 5 6/6/2003
A 1 8/5/2003
A 2 8/5/2004
The total for A should come out to be 11.00. There are multiple Items and multiple price changes.
If someone could point out how a inner join of this nature would work it will help me in my query. I guess the reason i say inner join is because I am joining multiple other tables to do my query.
My current Price Table has a start date and an end date and my query looks something like this. "Select SUM(PriceTable.Price * TransactionTable.Amount) From PriceTable Inner Join TransactionTable ON TransactionTable.Date Between PriceTable.StartDate and PriceTable.EndDate AND PriceTable.Item = TransactionTable.Item".
I want something like this because the tables need to be in the format above "Select SUM(PriceTable.Price * TransactionTable.Amount) From PriceTable INNER JOIN TransactionTable ON Max(PriceTable.Date) WHERE PriceTable.Date <= TransactionTable.Date AND PriceTable.Item = TransactionTable.Item".
The following is a VB code which I use it to check the existence of the record before I insert a new record into my SQL 7.0 database. When I run the vb code, I got an error which is "-2147217913 [Microsoft][ODBC SQL Server Driver][SQL Server]The conversion of a char data type to a datetime data type resulted in an out-of-range datetime value." I couldn't figure out what's wrong with my code especially the WHERE clause. Please help me look into this problem. TQ.

Have a LOB error which provides the corrupt PageID and this recommends a DBCC CHECKDB. However I'm unable to identify what the base table for the PageID. DBCC PAGE does not provide base table info (I think), DBCC PGLINKAGE has been retired in SS2005 and DBCC READPAGE doesn't work either.
Does any know of a valid SS2005 command or technique which will allow my to identify the base table for a PageID???

This little handy algorithm provides a truth table for any range of numbers between 0 and 65535 of any base between 2 and 36! As a twist, you can either return the digits concatenated or as separate columns.CREATE PROCEDURE dbo.uspTruthTable ( @FromNumber SMALLINT = 0, @ToNumber INT = 255, @Step INT = 1, @Base TINYINT = 2, @Concat BIT = 0 ) AS
WHILE @Step <= @Diff BEGIN INSERT#Numbers SELECT@Step + Number FROM#Numbers WHERENumber <= @ToNumber - @Step
SET@Step = @Step * 2 END
IF @Concat = 1 SET @SQL = 'SELECT Number, ''''' + @SQL + ' AS Digits FROM #Numbers ORDER BY Number' ELSE SET @SQL = 'SELECT Number' + @SQL + ' FROM #Numbers ORDER BY Number'
EXEC (@SQL)
DROP TABLE #NumbersYou can use the algorithm like these examplesEXEC dbo.uspTruthTable EXEC dbo.uspTruthTable 0, 255, 1, 8 EXEC dbo.uspTruthTable DEFAULT, 15, 1, 2 E 12°55'05.76" N 56°04'39.42"
Is there any way to get the base table/column from a view by supplying the view name/column name_in_view? I know about INFORMATION_SCHEMA.VIEW_COLUMN_USAGE, but it doesn't always work. Try it on a regular database, not pubs. Any help is appreciated!
I get few records into a Record set using Select Command. Then I update one Col in the Recordset and Updates the database table. I open the recordset in
I am getting "Insufficient base table information for updating or refreshing" Error some times. This Code executes in a Multi user Environment.
I tried to recreate this error condition on my local system by Deleteing/Updating the Reocrds from the table and even locking the table.
I get this error "Row cannot be located for updating. Some values may have been changed since it was last read."
Are both of these errors connected? or is there any way i can get rid of this error
The Code is somethng like this
Set objRs = New ADODB.Recordset objRs.CursorLocation = adUseClient objRs.Open strSql, SQLCON, adOpenDynamic, adLockOptimistic If (Not objRs.BOF) And (Not objRs.EOF) Then objRs.Fields("FLAG") = 1 objRs.Update VAR1 = objRs.Fields("0") Else MsgBox ("No Reocrds exist") End If
I'm implementing row-level security in a SQL Server database that uses Microsoft Access for the front end. I'm using a UDF (a view behaves the same way) to restrict access to specific rows of a base table based on membership in a role. According to the reading I've done, if the base table has DENY ALL permissions for the role, and the UDF has GRANT ALL, members of the role should be able to update records in the base table via the UDF, without having direct access to the base table. However, I find that unless I grant appropriate permissions on the base table, the user is unable to update the table via the UDF.
Is this expected behavior? Nothing I've read suggests I should have to grant permissions on the columns of the base table.
I have converted a access database to sql server 2000 for some reason i keep getting this error base table not found. I know the sql database is there and i also know the table is there. I'm not sure why i keep getting this error..
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
I do not insert/update/delete on the view directly.
For every insert/update in table A /B the values should get insert/update in the view respectively. This insert/update on view should invoke the trigger.
And I am unable to see this trigger work on the view if any insert/update occurs on base table level.
Trigger is working only if any operation is done directly on the view.
I have a problem with inserting records into table when an indexed viewis based on it.Table has text field (without it there is no problem, but I need it).Here is a sample code:USE testGOCREATE TABLE dbo.aTable ([id] INT NOT NULL, [text] TEXT NOT NULL)GOCREATE VIEW dbo.aViewWITH SCHEMABINDING ASSELECT [id], CAST([text] AS VARCHAR(8000)) [text]FROM dbo.aTableGOCREATE TRIGGER dbo.aTrigger ON dbo.aView INSTEAD OF INSERTASBEGININSERT INTO aTableSELECT [id], [text]FROM insertedENDGODo the insert into aTable (also through aView).INSERT INTO dbo.aTable VALUES (1, 'a')INSERT INTO dbo.aView VALUES (2, 'b')Still do not have any problem. But when I need index on viewCREATE UNIQUE CLUSTERED INDEX [id] ON dbo.aView ([id])GOI get following error while inserting record into aTable:-- Server: Msg 8626, Level 16, State 1, Procedure aTrigger, Line 4-- Only text pointers are allowed in work tables, never text, ntext, orimage columns. The query processor produced a query plan that requireda text, ntext, or image column in a work table.Does anyone know what causes the error?

So my data column [EODPosting].[MatchDate] is defined as a DATE column. I am trying to SELECT from my table where [EODPosting].[MatchDate] is today's date.
Is this not working because GETDATE() is like a timestamp format? How can I get this to work to return those rows where [EODPosting].[MatchDate] is equal to today's date?

can someone help me with th best way to look up a date in date dimension and populate the date id in fact. in the source date is dd/mm/yyyy and in date dimension columns are date id , year , quarter , month, day
I cannot create a measure that returns results for dates that do not exist in the fact table despite the fact that the components included in the measure contain valid results for these same dates.Creature a measure that counts the number of days where the "stock qty" is below the "avg monthly sales qty for the last 12 months" (rolling measure).Here is the DAX code I have tried for the measure (note that filter explicitly refers to the date table (called Calendar) and not the fact table):
Below you can see the sub measures (circled in red) are giving results for all days in the calendar.Highlighted in yellow are dates for which the StkOutCnt measure is not returning a result. Having investigated these blank dates, I am pretty confident that they are dates for which there are no transactions in the fact table (weekends, public holidays etc...).why I am getting an "inner join" with my fact table dates despite the fact that this is not requested anywhere in the dax code and that the two sub measures are behaving normally?
SO when i try to load from Master table to parent and child table i am using using expresssion like
select B.ID,A.* FROM FLATFILE_INVENTORY AS A JOIN DMS_INVENTORY AS B ON A.ACDealerID=B.DMSDEALERID AND A.StockNumber=B.STOCKNUMBER AND A.InventoryDate=B.INVENTORYDATE AND A.VehicleVIN=B.VEHICLEVIN WHERE convert(date,A.[FtpDate]) = convert(date,GETDATE()) and convert(date,B.Ftpdate) = convert(date,getdate()) ;
If i use this Expression i am getting the current system date data's only from Master table to parent and child tables.
My Problem is If i do this in my local sserver using the above Expression if i loaded today date and if need to load yesterday date i can change my system date to yesterday date and i can run this Expression.so that yeserday date data alone will get loaded from Master to parent and child tables.
If i run this expression to remote server i cannot change the system date in server.
while using this Expression for current date its loads perfectly but when i try to load yesterday data it takes current date date only not the yesterday date data.
What is the Expression on which ever date i am trying load in the master table same date need to loaded in Parent and child table without changing the system Date.
I have a scenario where I have to Update a table with date when there are new records in another table
For example:
I load ODS table with the data from a file in SSIS. the file has CustomerID and other columns.
Now, when there is new record for any customerID in Ods, then Update the dbo table with the most recent record for every CustomerID(i.e. update the date column in dbo for that customerID). Also Include an Identifier that relates back to the ODS table. How do I do this?
