I am working with a database containing time series data. In many, cases there is missing data. For example, while there might be a value for 2001-01-01T23:00:00, there is none for 2001-01-01T23:0100 (one minute later). I would like to replace the missing data with data from the previous record (if the previous record is the same date). Is that possible with T-SQL?

I am working with a database containing time series data. In many, cases there is missing dates. For example, while there might be a value for 2001-01-01, 2001-02-01, 2001-03-01, there is none for 2001-04-01 and 2001-07-01.

Any help much appreciated!
I need to create a function that replaces the data in a column with an 'X' based on the LEN of the data in the column. I created one that does a replacement, but it fills the column based on the max data length, and not the current length of the string or integer. An example of what I'm trying to accomplish.
Original data in a varchar(30) column:
thisisavalue
thisisanothervalue
thisisanothervalueagain
shortval
replaced with
xxxxxxxxxx
xxxxxxxxxxxxxxxx
xxxxxxxxxxxxxxxxxxxx
xxxxxxx
My current function is replacing the data like this:
xxxxxxxxxxxxxxxxxxxxxxxxxxxxxx
xxxxxxxxxxxxxxxxxxxxxxxxxxxxxx
xxxxxxxxxxxxxxxxxxxxxxxxxxxxxx
xxxxxxxxxxxxxxxxxxxxxxxxxxxxxx
I have a database of about 300,000 records.
The records were imported from a csv file.
One of the fields is duration.
The data in duration are like ths:
1 second: 0:01
26 minutes: 26:00
If i put the format of the field as time, the data are messed up.
0:01 becomes 1 minute.
26:00 becomes 1 day 2 hours.
I currently have duration as text.
How can i use sql or visual basic to replace all the data so that they can have the format "00:00:00"?
(0:01 becomes 00:00:01, 26:00 becomes 00:26:00)
I need the duration in time format in order to be able to make sum calculations.
I will be doing the same calculations every month so i need the above procedure to be able to execute it every time i need to.
Thank you in advace

View 4 Replies View RelatedI've got a report that is using a cube as a data source and I can't get the report to show all the data. Only data at the lowest level of the cube is displayed. The problem is that most of the data I'm concerned with is at higher levels. There's no problem with the MDX. I get the correct results when I run the query.
I'm using a table to show the results. I've also tried a matrix, but I get the same results. I'm using SSRS 2005 and SSAS 2000.
Anyone have experience with this? Am I missing something simple?

Hi, Experts
The project is a C/S data analysis system built with .Net 2.0 in windows environment, OS: Microsoft Windows 2003 R2 standard Edition Service Pack2, Database used in this project is: Sql server 2005. As a data analysis system, we need to load large amount of data from file to database, we do it by create a dts package and then do data loading by execute "m_Package.Execute(null, variables, m_PackageEvents, null, null)".
The problem is, we fount that DTS miss some data randomly sometimes, we can't find the rule till now. for example we've data as follows in data file, all data field splited by '|'

Hi, I was wondering if it is posible as in derived columns to replace an input column with the output one in Data Conversion?
What I can see that when a data conversion is done, only we can do it in a new column and not in the same one we are using as input.
Do you know if this it is posible?}
Thanks for your help!

I am working with a database named €œDocuments€? that contains 4 categories of text documents, each having its own number designation in an integer datatype column named SectionTypeId:
1 = Text
2 = Report
3 = Background
4 = Index
I would like to create a new column named €œDocType€? in which the integer data type for each document is replaced with a varchar data type letter (1 = T, 2 = R, 3 = B, 4 = I). I was able to easily create the new column and cast the data type from integer to varchar:
--CREATE NEW COLUMN €œDocType€? WITH VARCHAR DATATYPE
ALTER TABLE FullDocuments ADD DocType VARCHAR(1) NULL
Go
--UPDATE NEW COLUMN WITH CAST STRING
UPDATE FullDocuments SET DocType = CAST(SectionTypeID AS VARCHAR(1))
Go
But I have problems with the REPLACE method for replacing the numbers with letters. First I tried this based on the examples in MSDN Library:
--REPLACE NUMBERS WITH LETTERS
UPDATE Fulldocuments REPLACE (DocType,"1","T")
Which produced an error message: €œIncorrect syntax near 'REPLACE'.€?
Thinking that the datatype may be the problem, I tried this to convert to DT_WSTR data type prior to replace:
UPDATE Fulldocuments REPLACE ((DT_WSTR,1)DocType,"1","T")
Which produced the same error message: €œIncorrect syntax near 'REPLACE'.€?
I have never done a REPLACE before, so any suggestions for accomplishing this would be appreciated.
What is the correct syntax to replace a field data nvarchar(50)
Current data = 0020-10-02
Change = 2003-10-02
Thank you in advance.
Hello all, I am using the Import Wizard to pull in data from an Excel spreadsheet. One column in particular SQL Server sees as a float data type but it contains varchar data. So I change this in the wizard but some of these values are missing when I select * from Sheet1$ in SQL Server 2005. Any ideas why this would happen? I have formatted the particular column as text in Excel.
View 6 Replies View RelatedI currently have a LoginStatus and LoginName control on my asp.net 2.0 master page. When successfully logged in a message displays "You are logged in as" LoginName. Since I am using the user's e-mail address as the UserName the message will display as "You are logged in as johndoe@foo.com".
What I want to do is have the message display as "You are logged in as " FirstName LastName. FirstName and LastName are two new fields that I added to the table, aspnet_Users.
What I have done is to use the FormView control to display FirstName and LastName; however this always displays the first record in the aspnetdb database.
Is there a cleaner way (than the FormView control) to display the requested data, using the currently logged in user? I have access to Microsoft Expression Web and Visual Studio 2005, but I prefer Expression Web.
Thank you in advance

View 5 Replies View RelatedUsing Business Inteligence I have created a report that runs off a stored procedure. This report has three parameters. For this example we will say the parameters are A, B and C. parameters B and C can be passed a NULL. The Stored procedure when run on the SQL Server 2005 runs fine and gives me the expected data. I then created a report based off this Stored procedure. If I run the report and pass it parameter A and either Parameter B or C it works fine. If I run the report and only pass it parameter A then I do not get any data. I know the Stored procedure works because as I saind when I run it on the Server it runs fine. So the problem must be in the Report somewher, but I can't figure out where. I have other reports that use stored procedure and some with parameters that I pass a null value to and they work fine. But this one report is not pulling the data.
Has anybody heard of this before or have any ideas?
Any help would be greatly appreciated

I found a big problem. When we do a report it seems to be missing records. I am sure they should not be getting filtered out, given the filter in the report. I ran profiler on the SQL box it was pulling the data from, and it seems that they are all there. If I sort by the ID number of the records, then find the place it should be several are missing. But If I change the filter so that it filters everything but those records they show up. How could adding a filter cause more records to show up?

I faced a problem. I found all data/records of tables in a few databases were missing yesterday. I don't know what had happened. Can anyone tell me why? Can anyone tell me how to trace the root of the problem. Any log files I can trace? I fear it will happen again. My server is sql2000 and run on win server 2000.

Hello,
I have a sql 2000 database in which reports are generated on a monthly basis from the data inside on of my tables. The reports have been working fine, until some of the rows seemed to have disappered!
I know the data use to be in the table, since it is showing on the old reports, however, when I try to pull that same data, it is not in the database at all.
Does anyone have any ideas on what could have caused this or how I can resolve??
Thxs!!

I have loaded the text into an Excel Spreadsheet to work with it.
I was able to query our patient profile data base to get people with this insurance plan...but of course the data is never an ideal match.
For instance, some of the roster patients above have Middle Initials Concatenated to the First Name. In my database it is a mixed bag of missing initials, initials concatenated to first name or initials in separate Middle field. Thus a strict match on name is not going to work.
Date of Birth should hopefully be valid between both data sources.
Probably the best source of data to validate on would be the VW Acct# as I trust this to be the same in both sets of data. However in my patient data base it is buried in a note field preceded by a "Vital Works ID: " and then the number 602659-02. Generally it is the first part of the note field, but there could be additional notes preceding or trailing this Vital Works ID info.
An example of the query I was able to pull from the patient data base is as follows:

How could I now construct a query that would tell me what patients were in the eligibility roster that didnt have a match in the patient database?
I would like to then save that to Excel or somewhere that I could print it out from so I can have someone up date the database.
Thanks for your help.
Hi all,
I found problem with my database and was wondering if anyone here could shed some light on the issue.
I have two tables, Absences and AbsenceDates. The first one records the absence of an employee and the second one records a record for each day of the occurance. I do a full select on the second table and I see primary keys that do NOT exist in the select of the second table. so I dug further and here is what I found.
Select * from Absences (rowcount in Query Analyser is: 20883)
Select * from Absences Order By AbsenceID Desc (rowcount is 443)
The second select contains the data that I am missing in the first select. So, I called a friend and they said to run DBCC CHECKDB and I did. The data came back as follows...
DBCC results for 'Absences '.
There are 21337 rows in 243 pages for object 'Absences'.
CHECKDB found 0 allocation errors and 0 consistency errors in database 'EmployeeAbsenteeism'.
DBCC execution completed. If DBCC printed error messages, contact your system administrator.
now if you add up the rows that the other two selects return it comes to 21326, not 21337. I am assuming that the value that DBCC gets is from sysobjects and that some sort of update would need to be run for it be accurate. This I don't care about too much, what I really need is for my main select statement to return ALL of the data, not just what it feels like returning.
My experience is with programming mainly (6 years in .net) and not DBA, so any help would be greatly appreciated.
Cheers,
Brent

**** UPDATE *****
I tried running the following sql
select * Into Absences1 From Absences
the results were: (21337 row(s) affected)
now, I did a select * from Absences1
returned 20883 rows.. :(
****** UPDATE *******
I ended up fixing the following way.
Select * Into AbsencesFix WHERE PrimaryKey < 110577
GO
INSERT INTO AbsencesFix ({allfields}) (Select {allfields} FROM
Absences WHERE PrimaryKey > 110577)
Go
sp_rename 'Absences', 'Absences_oldCorrupt'
GO
sp_rename 'AbsencesFix', 'Absences'
Go
This little script did the trick, I can now select all the data in the table.
Hope the fix that was given to me by another DBA friend of mine can help someone out who has a similar problem.
After loading the BCP files that are created during the trigger/reporting events I've noticed that the data in the table is missingrecords. I've also noticed that the missing records (records in thetable but not in the BCP out files) seem to occur in contiguousblocks. Since the complete set of records exists in the table, Iassume this points to an issue in the way the TableUpdate script/Triggers interact with the system. But i tried to take out the bcpprocedure, do test on trigger, then no data missing, So, I think theproblem is still on bcp part. Could you help me with that?CREATE TABLE [EventUpdate] ([id] [int] NOT NULL ,[eventid] [int] NOT NULL ,[sequenceid] [int] NOT NULL ,[UpdatePass] [int] NULL) ON [PRIMARY]GOcreate trigger trgEventUpdate on EventLog For Insert,Update asinsert into EventUpdate (id,eventid,sequenceid) select ins.id,ins.eventid,ins.sequenceid from inserted insbcp script:bcp "select a.* from w..eventlog a, w..eventupdate b wherea.eventid=b.eventid and a.sequenceid=b.sequenceid and b.eventid<>-1and b.sequenceid<>-1 and b.updatepass=1" queryout 30sec-%TFN_NOW%.wrk -U <userwithaccess-P <password-S doserver -f EventLog.fmtThanks in advance for your reply!

I don't understand that message. I suspect the problem is that Excel is NOT installed on the box where I'm running the package. Does that seem right to you? Also, if Excel is needed on the box, how can I develop such a package on a laptop (in the airport) that doesn't have Excel?
Confused, but good!
