Is it possible to reference the data in another field within the same table?
Let's say that one column has a calculation, and a second column has a different calculation. Can the third column find the difference between the first two columns?
(I'm wondering if this is possible to do within the Layout View, not from the Data View)
Thank you!

I have a table that contains a Ref field and a TransactionDate field. For each Ref field there are mutliple Transactions. I am trying to put together a query that selects the Latest Transaction date for each Ref field in the table.
I tried:
SELECT *
FROM tabMediaTransaction
WHERE (TransactionDate =
(SELECT MAX(TransactionDate) AS Expr1
FROM tabMediaTransaction AS tabMediaTransaction_1))
But this only returns 1 record for 1 Ref field. I need 1 record for each Ref field

My question is simple, I'd like to do something I do in Jet ANSI-89 SQL. Mind you I'm just adding numbers here - they are not actual columns in 'SomeTable'
SELECT 1 AS A, 2 AS B, A+B AS C
FROM SomeTable
The Jet engine evaluates and does arithmetic on the Aliased column names - handy when they contain their own functions. The resultset would show:
A B C
1 2 3
However from what I can tell SQL Server 2005 is not picking this up. Is their an equivalent?

I am trying to eliminate a scalar function by rewriting a view. I currently have a structure similar to the following:
With FirstQuery as (SELECT Trial, SBOI, TBOI,
FROM TU
WHERE SBOI Between 22000 and 22999 and TBOI < 10000),
strt as (SELECT TOP 1 TimeOfEvent, Trial, SBOI, TBOI
From TU ORDER BY TimeOfEvent),
[Code] ....
What I trying to do is for the Trial, SBOI, and TBOI in FirstQuery, find the Start Time and Stop Time. TimeOfEvent is an integer in milliseconds. Say I have the following data:
TrialID SBOI TBOI TimeOfEvent
A 22000 5000 5
A 22000 5000 10
B 22000 5000 8
B 22000 5000 15
So the DISTINCT output would be:
Trial SBOI TBOI StartTime StopTime
A 22000 5000 5 10
B 22000 5000 8 15
The problem I am having is that strt is selecting the smallest time period. It doesn't seem to care what the current record in cte is. I thought that by using my joins, it would make it select smallest TimeOfEvent for the Trial, SBOI, and TBOI that are selected in cte. Obviously that is not the case. So, I was trying to add a WHERE to the strt Select Statement such as
WHERE TrialID = FirstQuery.TrialID and SBOI = FirstQuery.SBOI and TBOI = FirstQuery.TBOI but it isn't working either.
What can I do?

I am using vs 2010 to write my dtsx import scripts.I use a script component as a source to create a flat file destination file.Everything have been working fine,but then my development machine crashed and we have to install everything again.Now when i use the execute package utility to test my scripts i get the following error:
Error system.NullReferenceException: Object refrence not set to an instance reference.
In PreExecute section
TextReader = new system.io.streamreader(" file name")
In the CreateNewOutputRows:

I'm new to SQL and I'm trying to write a statement to satisfy the following:
If [Field1] contains text from [Field2] then return [Field3] as [Field4].
I had two tables where there were no matching keys. I did a cross apply and am now trying to parse out the description to build the key.

I need to pass in null/blank value in the date field or declare the field as string and convert date back to string.
I tried the 2nd option but I am having trouble converting the two digits of the recordset (rs_get_msp_info(2), 1, 2))) into a four digit yr. But it will only the yr in two digits.
The mfg_start_date is delcared as a string variable
mfg_start_date = CStr(CDate(Mid(rs_get_msp_info(2), 3, 2) & "/" & Mid(rs_get_msp_info(2), 5, 2) & "/" & Mid(rs_get_msp_info(2), 1, 2)))
option 1
I will have to declare the mfg_start_date as date but I need to send in a blank value for this variable in the stored procedure. It won't accept a null or blank value.
With refresh_shipping_sched
.ActiveConnection = CurrentProject.Connection
.CommandText = "spRefresh_shipping_sched"
.CommandType = adCmdStoredProc
.Parameters.Append .CreateParameter("ret_val", adInteger, adParamReturnValue)
.Parameters.Append .CreateParameter("@option", adInteger, adParamInput, 4, update_option)
.Parameters.Append .CreateParameter("@mfg_ord_num", adChar, adParamInput, mfg_ord_num_length, "")
.Parameters.Append .CreateParameter("@mfg_start_date", adChar, adParamInput, 10, "")
Set rs_refresh_shipping_sched = .Execute
End
Please help

I embedded a SQL query in excel that gets some datetime fields like "TASK_FINISH_DATE" .
How can I convert a datetime field to a date field in SQL in a way that excel will recognize it as a date type and not a text type?
I tried:
CONVERT(varchar(8),TASK_FINISH_DATE ,3)
CONVERT(Date,TASK_FINISH_DATE ,3)
CAST(TASK_FINISH_DATE as date)
**all of the above returned text objectes in excel and not date objects.

I am trying to drag data from Informix to Sql Server. When I kick off the package
using an OLE DB Source and a SQL Server Destination, I get DT_DBDATE to DT_DBTIMESTAMP
errors on two fields from Informix which are date data ....no timestamp part
I tried a couple of things:
Created a view of the Informix table where I cast the date fields as datetime year to fraction(5), which failed.
Altered the view to convert the date fields to char(10) with the hopes that SQL Server would implicitly cast them
as datetime but it failed.
What options do I have that will work?

DECLARE @datetimeoffset datetimeoffset(3)
DECLARE @datetime datetime
SELECT @datetimeoffset = '2012-11-08T17:22:13.575+00:00'
SELECT @datetime = @datetimeoffset
SELECT @datetimeoffset AS '@datetimeoffset ', @datetime AS 'datetime'
__________________________________________________ ___________
Result of above SQL is
@datetimeoffset datetime
2012-11-08 17:22:13.575 +00:002012-11-08 17:22:13.577
__________________________________________________ ____________
The result should be '2012-11-08 17:22:13.575', why the milliseconds value is incorrect

I have a very strange situation. I've increased the size of an NVARCHAR field from 8 to 9 in a database table. The format of the data that I enter will either be an 8 character field (123456-8) or a 9 character field (1234567-9). The '-' is critical.
It used to only accept the 8 character version, but after increasing the field size, if I try to insert the 9 character field version, it gets truncated after the '-', as though it's still only allowing 8 characters. But that only occurs when I include the '-' or other such characters like '#'. If I try to insert 1234567a9, it works. The following explains the outcomes:
Inserted Value -> Result in table
123456-8 -> 123456-8 *Correct
1234567-9 -> 1234567- *Wrong
123456789 -> 123456789 *Correct
1234567#9 -> 1234567# *Wrong
1234567a9 -> 1234567a9 *Correct
Why is it that characters such as '-' and '#' are truncating the value, but only if the string is 9 chars long?
I'm currently using a direct t-sql insert statement in SQLExpress. The field is a simple NVARCHAR(9) field.

DECLARE Loan_cursor CURSOR FOR
SELECT Loan_No,store
FROM loan
WHERE maturity_date > '2001-04-30' and loan_no like 'ABL%'
OPEN Loan_cursor
-- Perform the first fetch.
FETCH NEXT FROM Loan_cursor
-- Check @@FETCH_STATUS to see if there are any more rows to fetch.
WHILE @@FETCH_STATUS = 0
BEGIN
Declare @LoanNo varchar(12)
** Set @LoanNo = Loan_No
-- This is executed as long as the previous fetch succeeds.
FETCH NEXT FROM Loan_cursor
END
CLOSE Loan_cursor
DEALLOCATE Loan_cursor
when l run the cursor l get the error
Server: Msg 207, Level 16, State 3, Line 15
Invalid column name 'Loan_No'.
.
If l reference it as Set @LoanNo = LoanTable.Loan_No l get the error
Server: Msg 107, Level 16, State 3, Line 15
The column prefix 'loan' does not match with a table name or alias name used in the query.
All l'm trying to do is to compare the loan number that l get from the cursor to the value in the loans table. Maybe reference is a better word

Hi All ...
WITH myCTE (x,y,z) AS (SELECT x,y,z, from myTable)
SELECT x,y,sum(z) from myCTE
SELECT y,z,sum(x) from myCTE
the second SELECT fails, and says invalid object name. does the CTE go out of scope after i reference it once?
never mind the semantics of what I am SELECTing, I just want to be able to reference the CTE more than once in my SP
am I trying to use the CTE in a way that was not intended?

Hi,
I'm importing an Access database to SQL Server 2000.
The issue I ran into is pretty frustrating... All Memo fields that get copied over (as Text fields) appear to be fine and visible in SQL Server Enterprise Manager... except when I display them on the web via ASP - everything is blank (no content at all).
I didn't have that problem with Access, so I ruled out the possibility that there's something wrong with the original data.
Is this some sort of an encoding problem that arose during database import?
I would appreciate any pointers.

I have a table called BidItem which has another table calledBidAddendum related to it by foreign key. I have another table calledBidFolder which is related to both BidItem and BidAddendum, based on acolumn called RefId and one called Type, i.e. type 1 is a relationshipto BidItem and type 2 is a relationship to BidAddendum.Is there any way to specify a foreign key that will allow for thedifferent types indicating which table the relationship should existon? Or do I have to have two separate tables with identical columns(and remove the type column) ?? I would prefer not to have multipleidentical tables.

I am trying to populate a field in a SQL table based on the valuesreturned from using substring on a text field.Example:Field Name = RecNumField Value = 024071023The 7th and 8th character of this number is the year. I am able toget those digits by saying substring(recnum,7,2) and I get '02'. Nowwhat I need to do is determine if this is >= 50 then concatenate a'19' to the front of it or if it is less that '50' concatenate a '20'.This particular example should return '2002'. Then I want to take theresult of this and populate a field called TaxYear.Any help would be greatly apprecaietd.Mark

I know there has to be a way to do this, but I've gone brain dead. Thescenario..a varchar field in a table contains a date range (i.e. June 1,2004 - June 15, 2004 or September 1, 2004 - September 30, 2004 or...). Theusers have decided thats a bad way to do this (!) so they want to split thatfield into two new fields. Everything before the space/dash ( -) goes intoa 'FromDate' field, everything after the dash/space goes into the 'ToDate'field. I've played around with STRING commands, but haven't stumbled on ityet. Any help at all would be appreciated! DTS?

Hi all,
i've a reasonable amount of experience with MS Access and less
experience with SQL Server. I've just written an .NET application that
uses an SQL Server database. I need to collate lots of data from around
the company in the simplest way, that can then be loaded into the SQL
Server database.
I decided to collect the info in Excel because that's what most people
know best and is the quickest to use. The idea being i could just copy
and paste the records directly into the SQL Server database table (in
the same format) using the SQL Server Management Studio, for
example.
Trouble is, i have a problem with line feed characters. If an Excel
cell contains a chunk of text with line breaks (Chr(10) or Chr(13))
then the copy'n'paste doesn't work - only the text up to the first line
break is pasted into the SQL Server database cell. The rest is not
pasted for some reason.
I've tried with MS Access too, copying and pasting the contents of a
memo field into SQL Server database, but with exactly the same problem.
I've tried with 'text' or 'varchar' SQL Server database field formats.
Since i've no experience of using different types of databases
interacting together, can someone suggest the simplest way of
transferring the data without getting this problem with the line feeds?
I don't want to spend hours writing scripts/programs when it's just
this linefeed problem that is preventing the whole lot just being
cut'n'pasted in 5 seconds!
cheers
Dominic
