Meta Data Synchronization With Excel File Source Once We Update The File

Dec 28, 2007



hi all;

1. Excel file Source--> monthly Revenue details
2. Derived Colum Transoformations
3. Oledb Destination

its my flow in one of my packates (ETL job)
Excel file contains monthly revenue details, i wanna import the excel data to my database staging table, so i've created the package.
its working fine...

Problem
if we change the new data for the next month and running the package its not running;
the same file, same format, only we delete the contents, of the file except first row of the excel sheet,
and pasting the new data;
new data is coming from Oracle DataBase in the form of excel sheet ( manually they will copy the data and sending to us)

i open that package in design mode and while double clicking the excel file source it says <column name>'s Meta Data needs to be synchronized
Do you want to Fix this issue automatically with the available external column's meta data

Clearly noted that its a data type issue; i have changed the corresponding data types as it is in the previous Excel sheet which is equivalant to the Table its copying to.

now the package is running with validation warnings, External Column "Invoice Amount" needs to be updated...etc. some 2 or three warning messages i can able to see in the package Execution wizard,

ok, i'm ready to accept these warnings, and i want my package running from my server;( packages had been deployed in to the Centeralized server; every time if we want to run the package, we have the asp.net webpage, that is executing the package in an On_click event)

The package is not running from the server, its due to the meta data change in the Excel file( i guess)

please suggest me some guide lines to resolve this meta data issue, i want my excel sheet meta data should not change when we have new updates in it;

otherwise suggest me some solutions that i can validate the excel sheet before running the package and testing whether the data is in correct format or not? its a kind of Data Profiling activity;

i know its some what crazy, but i need to maintain the system with permanent solution, instead of facing this meta data mismatch issue!!!

some what lenthy explanation--> its needed for my dear powerful microsoft responders. i think i 've explained my problem clearly, if i don't let me know your queries, i'll try my level best.

Pipeline Error-excel Source-data Reader Does Not Read In Meta Data

Apr 16, 2008

Hi all, i got this error:


[DTS.Pipeline] Error: "component "Excel Source" (1)" failed validation and returned validation status "VS_NEEDSNEWMETADATA".

and also this:

[Excel Source [1]] Warning: The external metadata column collection is out of synchronization with the data source columns. The column "Fiscal Week" needs to be updated in the external metadata column collection. The column "Fiscal Year" needs to be updated in the external metadata column collection. The column "1st level" needs to be added to the external metadata column collection. The column "2nd level" needs to be added to the external metadata column collection. The column "3rd level" needs to be added to the external metadata column collection. The "external metadata column "1st Level" (16745)" needs to be removed from the external metadata column collection. The "external metadata column "3rd Level" (16609)" needs to be removed from the external metadata column collection. The "external metadata column "2nd Level" (16272)" needs to be removed from the external metadata column collection.


I tried going data flow->excel connection->advanced editor for excel source-> input and output properties and tried to refresh the columns affected.
It seems that somehow the 3 columns are not read in from the source file?
ans alslo fiscal year, fiscal week is not set up up properly in my data destination?
anyone faced such errors before?

Thanks

Certain Numeric Fields Not Read From The Excel File When Using A Excel File Source.

Jul 20, 2006

I have the Excel Connection Manager and Source to read the contents from an Excel file. For some reason couple of numeric fields from the Excel worksheet are brought over as nulls even though they have a value of 300 and 150. I am not sure why this is happening. I looked into the format of the fields and they are set to General in Excel, I tried setting them to numeric and that did not help.

All the other content from the excel file is coming thru except for the 2 numeric fields.

I tried to bring the contents from the excel source to a text file in csv format and for some reason the 2 numeric fields came out as blank.

Any inputs on getting this addressed will be much appreciated.

Thanks,

Manisha

How To Change Data Types In Excel Source File?

Mar 8, 2006

I'm getting a bit lost in SSIS. I've got an Excel source file that I'm trying to load into a table. I keep getting validation errors that warn about not being able to convert between unicode and non-unicode string data types.

I'm trying figure out where I have to change this and am frankly confused. It seems SSIS is selecting various columns as unicode/WSTR data types, but I want them to import as regular string types.

On the Data Flow tab in SSIS, I right-click on the source Data Flow component (the Excel file) and select Show Advanced Editor. Then on the last tab, Input and Output Properties, there's a tree view for the Excel output. There are "External Columns" and "Output Columns" containers in the tree view.

I tried setting some of these but they don't seem to "take". Do I need to change the data type for each column under both the External and Output columns?

That seems like a lot of work! And, as I say, I tried setting some, but I still got the same validation errors. So, then I go back to this spot (Advanced Editor -> Input and Output Properties tab) and my changes seem to have been lost.

Any help would be appreciated!

Import Excel Data From User-selected Source File

Dec 4, 2007

Is it possible to import data from an Excel spreadsheet using OPENROWSET or OPENDATASOURCE without having to explicitly define the filepath of the source file? Currently, I have this piece of code within a sproc:


INSERT INTO [dbo].[ProductionRequirementDetail]

([ProductionRequirementHeaderID], [SKU], [Quantity])

SELECT @ProductionRequirementHeaderID,

[SKU],

[LAMPS]

FROM OPENROWSET ('Microsoft.Jet.OLEDB.4.0','Excel 8.0; Database=C:WeeklySchedule.xls', 'SELECT * FROM [Master$C5:Q65536]') AS XL

LEFT JOIN [dbo].[PartMaster] ON (RIGHT([XL].[CODE], 7) = [PartMaster].[SKU])

WHERE [SKU] IS NOT NULL

AND [CODE] IS NOT NULL

AND [LAMPS] IS NOT NULL

AND [LAMPS] > 0

AND [LampTypeID] = @LampTypeID




I would like to remove the hardcoded reference 'Database=C:WeeklySchedule.xls' and replace it with a parameter for the filepath. Is this possible? This is in SQL Server 2000. Also, if there is a way to do this with DTS I'd be open to doing it that way too.

DTS With Excel File As Source

Feb 3, 1999

I'm trying to write a DTS package that reads data from an excel spreadsheet. I'm having a problem getting all the data from the spreadsheet, seems that OLE DB is "too" smart. There is one column that has either numeric values or text values in its row cells. When I browse the spreadsheet in DTS (transform properties, browse button) I only see the text values. OLE DB has placed nulls or blanks into the cells with the numeric values. If I edit the spreadsheet to change the column header to contain a number, then the browse window shows only the numeric values and blanks out the text values. Any suggestion on how to get OLE DB/DTS to treat the numeric values as text? In the spreadsheet, I've tried changing the cell formats to text and to general. This had no effect.

Dynamic Source For Excel File At Runtime

Aug 23, 2006

Hi,

I've seen a number of posts similar to this but i still cannot figure out what i need to do to get it working. So here goes with a couple of newbie questions.

Question 1:
Once created how do i go about executing a SSIS package. I want to be able to call it from a C# application from which i pass in a couple of parameters?

Question 2:
How do i go about setting the file path of my Excel source to a dynamic value passed at runtime. I want to be able to loop through a number of Excel files and do some processing on them. I've set up a variable (which i think i need to do) after that i get stuck however. Some other posts suggest configuration packages but i cannot get my head around how they work?

Any help on this matter would be gratefully recieved.

Thanks in advance,

Grant

Cannot Import Excel Source File With Empty Last Column

Oct 23, 2007

Hi All,

I have a particular issue that has been causing me some problems for a while. I have an SSIS package that imports an excel file into my database, and then performs various data manipulation that I won't go into. The problem I am having is at the import end. The excel source file I am working on is provided to me by my client. It is a fixed format and doesn't change, it contains a header row and there are 32 headings. The trouble I am having is that quite often, the last column is empty, i.e. it contains no data. The header is still there, but theres no data underneath. When I try to import this file using my SSIS package it fails, and complains about needing to remove the metadata for this final column from the External Columns list (VS_NEEDSNEWMETADATA). When I try to preview this file in the properties of the Excel Data Source, the last column does not exist. It's as if it's determining that as there is no data in that final column, that it's unnecessary and not part of the data set, even though it has a header.

Now I've done a bit of research, and found cases that a sort of like mine, I know that the excel file has the first 8 records sampled to determine the data format. This problem suggested to use the IMEX=1 extension in the connection string, which didn't help. I also discovered that when using flat files, if you have odd numbers of columns in your comma seperated list there can be problems. But neither of these issues seem to match the issue I'm facing.

Has ANYONE had a similar problem to me, and can anyone offer any kind of assistance regarding what I need to do to import an excel file that may or may not have data in the final column?

Thanks in advance,

Paul

Update Table From Flat File Source

Aug 31, 2006



Hi all,

I'm trying to work out how to update a table from a flat file source.

I could use the simple way of using OLE DB Command with

UPDATE <tblName> SET Column1 = ?, Column2 = ?, <etc> WHERE ID = ?

then using the mapping to join the parameter fields.

However, this (maybe!) a slow process when you have potential 500k+ records in the source file (and approx 150 files to process!)

What I would like to do is the following statement but I'm not sure if this is possible?

UPDATE <tblName> SET Column1 = sourceColumn1, Column2 = sourceColumn1, <etc> FROM <sourcefile> WHERE ID = sourceID

I've also thought about importing the sourcefile into a Recordset Destination and trying to use the variable in the SQLCommand but I'm not sure how to do this...

Does anybody have any ideas on how this could work or an alternative solution?

Thanks in advance....

Integration Services :: Source Excel File Causing Failure In Agent

Aug 13, 2015

I have a package from SQL Server 2008 R2, that loads data from .xlsx file to database table.There are total 15 columns and 14000 rows in the .xlsx. The package runs fine in BIDS. But the same package in SQL Agent fails with error "omponent "Excel Source" (1)" failed validation and returned validation status "VS_ISBROKEN".

When I tried to run the package by deleting the half of the records for first 7000 rows it ran successfully in agent. Then the second half (last 7000 rows) also succeed from agent job. So, there is no issue with the data/datatypes.The agent job is able to run with record upyo 11000 rows in .xlsx. When I am running for 12000 rows it is failing.Is there any problem with the number of records in .xlsx or size through SQL Agent?

I am running the package from a Proxy account in sql agent job.

File System Task - Dynamic Source File Name

Feb 27, 2008



Hi All,

I have a source files folder where the files generated everyday.
My goal is pick the latest file and copy this single file to another folder.
I used the Foreach loop container and got the latest file and stored the file name to a varible i.e. LatestFile
Then i want to use the File System Task to copy this to the destination.
On the beginning, I could not setup the Latestfile since I don't its name then, so when I setup the Source Connection property of the File system task, it is not allowed to leave the SourceVarible as blank!

Any suggestion?


Thanks

Regarding The Dynamic File Change Within Flat File Source.

Mar 28, 2006

Hi,

we have one requirement to run the package daily basis.

The package should run at specific time on that day.

we are using windows schedular for that.

we will have one new flatfile everyday.

Is there any process to attach this file to flat file source dynamically?

The requirement is,

The flat file should be able to read the new flatfile everyday.

we have no option change it manually, the flatfile source should have to take the file automatically at that time.

So that it can take that flatfile and load it into database table.

Redirect Bad Data From Flat File Source

Apr 17, 2008

Hi, all,

I have this SSIS data flow ( Flat file to sql server) that I want to add a step to redirect any "bad" data instead of fail out.

I had the red arrow hocked up to a sql new table to dump the bad data, but the flow still failed.

Here is the first error, and I knew what was wrong. A description field in that line has pipe(|) character in it, which also happen to be the column delimiter in this case.

[Flat File Source [1]] Error: Data conversion failed. The data conversion for column "Column 22" returned status value 4 and status text "Text was truncated or one or more characters had no match in the target code page.".

I knew if I fixed the data, every thing will be fine, but I just want to use this redirect feature of SSIS. Is there a place where I can turn off validation, or do something to make it work?

Thanks!

Restore To New Db Restores Less Data Than What Is In The Source Backup File

Jan 25, 2006

I am trying to create sql code that restores a backup of a master database to a new database on the same server. It “seems” to run correctly as no errors are produced. However, the most recent updates to the master database are not present in the new databases. All databases are using the Full recovery model. What is really strange is that if I do (what I think is) the same function in Enterprise Administrator, the restore works fine! For both methods I used the same backup file!



Any and all help is sincerely appreciated.


The master databases from which the backups are made start with “MODTRNMaster”

The databases which are created from the restores start with “M1_” and “M2_”. (We call them training room databases.)



My script for backing up the master databases:



-- Backup the master training database

backup database MODTRNMaster
to disk = 'f:kupMODTRNMaster.bak'

backup database MODTRNMaster_IMG
to disk = 'f:kupMODTRNMaster_IMG.bak'

backup database MODTRNMaster_MNC
to disk = 'f:kupMODTRNMaster_MNC.bak'

backup database MODTRNMaster_VM
to disk = 'f:kupMODTRNMaster_VM.bak'

go


This is the restore script for restoring the first training room databases. I’m hoping that there is just something simple that I’m overlooking in these restore statements! J



-- Restore the backup of the master training database into the

-- training room #1 database.

use master
go

drop database M1_MSLH
go


restore database M1_MSLH
from disk = 'f:kupMODTRNMaster.bak'
with move 'DEV5_Data' to 'f:mssqldataM1_MLSH.mdf',
move 'MM' to 'f:mssqldataM1_MLSH_1.mdf',
move 'AMB' to 'f:mssqldataM1_MLSH_2.mdf',
move 'DM' to 'f:mssqldataM1_MLSH_3.mdf',
move 'IMM' to 'f:mssqldataM1_MLSH_4.mdf',
move 'ED' to 'f:mssqldataM1_MLSH_5.mdf',
move 'DEV5_Log' to 'f:mssqllogM1_MLSH_log.ldf',
recovery

go



Thanks in advance
