Importing Only Latest Data
Jan 24, 2008
I've never worked with SSIS before, and I need to figure out how to import only the latest data from an Access table into a SQL Server table. I have a .dtsx file written by someone who no longer works at my company that simply truncates the SQL Server table and copies the entire Access table back into it. This is no longer effective simply because of the amount of data involved (it has become extremely slow over time).
Since each row includes a timestamp, ideally I would look at the latest timestamp in my SQL Server table and retrieve only those rows from Access that have a timestamp later than that. I have no idea how to do this in SSIS.
Logically, I think something like this is called for:select max(timestamp) as latest from SqlServerTablestore the result in a variable somehow and create a query to select * from AccessTable where timestamp > [latest]copying the results of that query into the SQL Server table. How do I do something like that? And if that isn't a feasible way to do it, what way would be better?
Thank you for indulging a newbie.

I need help in constructing SQL. I have the following table
Document
PKEY id varchar
DocumentRev
PKEY docID -> Document.id
PKEY rev int
TransmitDoc
PKEY transmitNo int
PKEY projectID varchar
PKEY documentID -> DocumentRev.docID
PKEY rev -> DocumentRev.rev
Given a transmitNo and projectID, what is the SQL can be used to get all document that have latest/largest rev that is not in TransmitDoc?
example I have 4 document.
documentA rev 1
documentA rev 2
documentB rev 1
documentB rev 2
if the given transmitNo and projectID have
documentA rev 2
The result should only show
documentB rev 2
documentA rev 1 and documentB rev 1 should not be shown because it is not the largest.
Thanks,
Max

Good day,
My report links to a SQL server and is not showing the latest information. If I open it now and look at the report, close it and open it again ina few hours it will show the same report as I looked at originally. When I push the reports refresh button then the data refreshes and shows all the information.
The execution for the report is already set to: Do not cache temporary copies of this report
Why does this happen? I have about 40 reports that work perfectly but this one is giving me problems, any one got any ideas for me? Please help.
Thanks

Hi,
I'm trying to write some SQL which will give me the following result from the table below..
Currently I can do each of the PRICEx fields in a seperate query then join the results together. I do this by getting the MAX(Date) WHERE PRICEx IS NOT NULL then using that date to get PRICEx, and then repeat until I've done all the PRICE fields.
This is acceptable for a small selection, but for a large selection this can get quite slow. I was just wondering if there is there a way to do this in one single SQL without having to join the table to itself 3 times (for all 3 PRICE fields)
Source Table:
ProductID
MarketID
Date
PRICE1
PRICE2
PRICE3
1
2
1/01/2006
2.45
3.4
2.97
1
2
2/01/2006
2.51
3.5
NULL
1
2
3/01/2006
NULL
3.6
NULL
1
2
4/01/2006
NULL
NULL
NULL
Result:
ProductID
MarketID
PRICE1
PRICE2
PRICE3
1
2
2.51
3.6
2.97
Thanks,
Victor.

I have two table, tblCharge and tblSentence, for each charge, there are one or more sentences, if I join the two tables together using ChargeID such as:
select * from tblCharge c join tblSentence s on c.ChargeID=s.ChargeID
, all the sentences for each charge are returned. There is a field called DateCreated in tblSentence, I only want the latest sentence for each charge returned, how can I do this?
I tried to create a function to get the latest sentence for a chargeID like the following:
select * from tblCharge c join tblSentence s on s.SentenceID=LatestSentenceID(c.ChargeID) but it runs very slow, any idea to improve it?
thanks,

In our Microsoft Dynamics Nav instance we have a Sales Header Archive table - into which copies of the Sales Header are placed, with 3 items forming the compound key:
Document Number
Version
Occurrence number
so if doc 1 is archived, then the records would be
Doc# | Version | Occurrence #
1 | 1 | 1
When a second copy is archived a new record is added:
Doc# | Version | Occurrence #
1 | 1 | 1
1 | 1 | 2
and then when maybe a 3rd version is archived a 3rd entry added
Doc# | Version | Occurrence #
1 | 1 | 1
1 | 1 | 2
1 | 2 | 2
This is for EACH document and I now need to retrieve the dataset which is the latest version of each document... but I'm drawing a blank!
If I
select [Doc#], max([Version]) as [V], max([Occurrence #]) from (table) group by [Doc#]
then I get the distinct list of docs, but I now need to use this list to select the records which match this criteria, from this table.
How do I select just these?
I thought (wrongly) that I could simply say:
Select * from Invoice Table where
Invoice.[Doc#], Invoice.[V], Invoice.[Occurrence #] in
(select [Doc#], max([Version]) as [V], max([Occurrence #]) from (table) group by [Doc#])

Let's say I have a table of data as per the below..
I'm trying to extract only the green highlighted items..
The rules applied are: Only the latest data concerning all cases, and only 1 line (the latest) per case.
As you can see in the image, I don't want the 2nd,3rd, and 4th record extracted cause they are all superseded by more recent records (identified as they are further in the table).
I've considered using either Distinct or Having? but can't get that to work.. If I could use Distinct but then ensure it's the latest record in the table that would be perfect.

I setup this package to import data from a Sharepoint list to a SQL Server data table. The primary key of my SQL table is mapped to the Title column of my Sharepoint list. There is a possibility that duplicate values will be entered in the Title field of the Sharepoint list. So when importing data into my table via SSIS, my package always error-out when there it comes across duplicate values. how you others have managed data integrity when importing from a Sharepoint list with the Title column being mapped to the primary key of a table.

I have created a simple package that uses a sql command to pull data from an oracle database and inserts the data into a sql 2005 table. Some of the data fields that i am pulling from contain two digits after the decimal point, however this data is lost when it gets into sql. I have even tried putting the data into a flat file, and still the data is lost.
In the package I have a ole db source connection which is the oracle database and when i do the preview i see all the data I need. I am very confused and tried a number of things to get the data into sql, but none work. Any ideas would be very helpful.
thanks

Hi all :)
I'm wondering if SSIS will be the solution to the problem I'm working on.
Some of our customers give us an Excel sheet with data they want to insert or update in the database.
I've created a package that will take an Excel sheet, do some data conversion so the data types match up and after that I use a Slowly Changing Data component to create the insert/update commands.
This works great. If a customer adds a new row to the Excel sheet or updates an existing row changes are nicely reflected in the database.
But now I€™ve got the following problem. The column names and the order of the columns in the Excel sheet are not standard and in the future it could happen a customer doesn't even use an Excel sheet but something totally different.
Can I use SSIS for this? Is it possible to let the user set the mappings trough some sort of user interface? I€™ve looked at programmatically creating the package but I€™ve got to say that€™s quit hard to do€¦ It would be easier to write the whole thing myself than to create the package trough code ;)
If not I thought about transforming the data in code before I pass it on to the SSIS package in something like XML. That way I can use standard column names and data types.
So how should I solve this problem? Use SSIS or not?
Thnx :)

I'm new to SQL and DTS packages. I am trying to import data from an excel spreadsheet to an SQL server table via DTS package. It seems that the excel task looks at the first few records in a column to determine the datatype for that column. If the first few records are text, the entire column is imported as text. If numeric, the entire column is imported as numeric.
There are about 25,000 records. In one field, the most important one, about half of the records begin with letters and the rest are all numbers. It is the subscriber ID field, and some subscriber IDs are all numbers, some are letters and numbers. The entire column should be imported as text. However, when I run the transform data task from the excel connection, none of the records that are all numbers are imported. I end up correctly importing only 13,000 of the 25,000 records. The rest are imported with the subscriberID field as <NULL>.
I tried using the CAST or CONVERT function in the SQL query, but get the error message "Undefined Function."
Can anyone give me some help? Thanks,
Jim

I am creating a DTS package that is combining several tables, converting one column of data to a new column removing all special characters, then exporting the unique data based on this column and another column, and the max of other duplicates to a new table.
Now that I have the data in this table, I want to import any data that is not in my main table.
This "CLEANED" table does not have a designated "key" column, but the table I want to import the unique items does have an ID column that is also a primary key column.
DTS seems to want me to have a Key column to reference when importing from the CLEANED table to the MAIN table.
How would I go about checking the MAIN table against the CLEANED table, having DTS import only the unique items from the CLEANED table that are not present in the MAIN table based on three columns? The rest of the columns I want to just extract the MAX data from the duplicates.
Now here is the query I use to extract the unique values from the "CLEANING" table to get the data to the "CLEANED" table, but do not know how to use this to import into the MAIN table using something similar.
Code:
select
partno2,
MAX (partno) as partno,
alt,
MAX (C_alt) as C_alt,
Max (cmpycd) as cmpycd,
MAX (type) as type,
compFN,
MAX (pndesc) as pndesc,
MAX (equipment) as equipment
into tbl_CLEANED
from tbl_CLEANING
group by partno2, alt, compFN
ORDER BY partno, compFN
The three main columns I need to check against are:
partno2
alt
compFN
I have named the columns the same in both tables.
partno2 is the column that has been copied from partno with all special characters & spaces removed. This is the main column I am using as a reference for unique values, then if no match, I have it check against the alt column, then the comFN column. If there are no matches in any of these columns, then I want to extract the data to the MAIN table.
How can I compare these tables and import only unique info to the MAIN table?
In addition, how can I also check items that are the same in both tables and update the MAX info for the other columns (not the three I use for reference - these I need to leave alone) and update those if there is more data in the CLEANED table then in the MAIN table?

I have created a DTS package for SQL Server, saved this as a VB file and upgraded this to the .NET framework.
It is now saved in a file called Shortages.vb.
What I want to do now is add this to an existing ASP.NET project and be able to call this DTS function by the click of a button.
Is this possible and how can I go about it? Can I just add it to the Click event of a button?

Hallo every one,
I', working for a school project.
The setuation is an old database that has to be repaird.
All the data from each table of the old data base are stored in different tabdelimited text files.
I designed a new database, but the tables are a little different.
When I try to import the data I get some errors, because of the changed tables.
An example of my new setuation is a new table thas as colums from 2 different tabdelimited text files.
My question is, how do I solve thos problem!
Do I have to use DTS?
What do I have to do.
tnx

I have a process that calls a proc that BCP's a delimited file into a table. Well the SOX police say a header and footer must be added to the file. Needless to say this screws my BCP process. Does anyone know how to strip a header and footer record from a text file using transact sql or have any other suggestions to strip the records?

we are trying to import data from a flat file using an uptick (`) as a column separator and {CR/LF} as a record terminator. There is a variable number of columns for each record. The initial record in the flat file has 3 columns. Upon processing this record, the import sets all records to 3 columns and does not read the column separators past the second column (even though there may be up to 7 columns in the record).
This method worked ok in DTS2000 and it works with Excel. Any suggestions?
Thank You

There's alot of discussion in this Forum concerning the importation of data into SSE.
I recently discovered that you can quite easily export tables directly from MSAccess to SSE. Simply 1) select the desired MSAccess table, 2) choose 'Export' from the file menu, 3) in the 'Save as Type' drop down, select ODBC databases(), 4) at this point, an 'Export' dialog with the name of the selected table appears, 5) click 'OK', 6) the Data Source Manager appears - go to 'Machine Data Source' and select a DSN that connects to SSE (you need to have set this DSN up before), 7) click 'OK' and and your table will be exported from MSAccess to SSE.
For whatever reason, the table you exported will always end up in SSEs 'Master' database tables. There is probably some work-around to correct this, but I havnt spent much time fooling with it.
Now, MSAccess has a very good parser for importing several types of external data, including Excel worksheets, CSV files, and text data. However, to get a satisfactory into MSAccess, you may need to edit your data files. Then, to import the data, from MSAccess select 'Get External Data' -> 'Import' from the File menu and just follow the instructions.
BTW, there is alot of confusing discussion concerning the ability of SSE to use DTS. Some have said that it is not supported, only in the full-blown version. Others have suggested you can download the DTS application from Microsoft and use it with SSE although it does not show up in the SSEMS directory tree.
I downloaded the file 'SQLServer2005_DTS.msi' and tried to install it. It appeared to install OK but I cannot find it anywhere on my machine. Weird, eh.
While most of this thread is in the way of a comment, I have a couple of questions:
1 - Is there some way to connect a machine DSN to a database in SSE that is other than 'Master' ?
2 - Are there better ways to import data into SSE ?
3 - Is there some way to move or copy a table from one SSE database to another ?
BTW, please do not respond to this thread by posting some link. Many of the links I have attempted to follow from this Forum are either irrelevant to the posted problem or are no longer available. If I wanted that kind of help, I could use Google or go to the library. Try to answer the question(s) directly. If you don't know the answer, say so, or at least, don't answer at all.

Here is the scenario: I have an excel spreadsheet that contains 182 columns, and I need to move this data into a semi-normalized database for reporting. The SQL Server database schema has 11 tables. Some of the tables are going to use identity columns for their PK, other tables are using a value that comes from this spreadsheet for their PK values.Anyway, I have never done a DTS package of any significance before, and know I most likely need to write some VBScript to handle sticking data into the proper data tables, etc.I am just hoping someone can point me at a good resource, give me an alternative means of doing this (this is a process that will need to happen whenever a new Excel spreadsheet is dropped into a folder or on a schedule, either one). I would love to write some C# code to handle these things, but a DTS package would probably be the best, I just don't know where to start.Thanks,

Hi All,I'm coming from using MySQL, and in their dialect you could pull data from one table to another using the following: INSERT INTO Table1 (fname, lname)VALUES( SELECT fname, lname FROM Table2 )Let's assume Table1 is a simple table with the fields ID (PK/Identity), fname, and lname. This query would grab all the first and last names out of Table2 (fname and lname fields) and insert them into Table1, generating the ID for each new row.How would I do this in T-SQL?

The source file for the import is a text file , CSV format. I want the users to click on the "Import" button placed on my webform and supply the souce file and the data should get imported into the SQL Server 2000 database table.
I want to know the various ways to implement this. Is it possible to invoke the DTS and then DTS will itself guide the users do the import? or if i need to write a SQL query , what would that be like??
