How To Update The Source Columns'metadata Automatically?
Dec 14, 2006
Take a Dataflow Task, with an OLEDB Source Component and an OLEDB Destination Component in it. The Source component's Source is stored in a SQLQuery variable, and the Destination component's Destination is stored in a TableName variable. The Dataflow Task is put into an For Loop container.
I just want to do one thing:
In the For Loop, everytime it send a new value to the SQLQuery variable and the TableName variable, then I could use it to transfer many tables in a same logic.
My question is: Really, I could send new values to the variables and make it go. But everytime it says "The external metadata column collection is out of synchronization with the data source columns." Because the external metadata was recorded and not be change automatically everytime of Loop.
How to update the source columns'metadata automatically?

Hello,
I have a SSIS package with a Data Flow task. This task transfers the data from SQL Server 2000 to a table in SQL Server 2005.
I deployed and tested this package on the Test Server. Then put this package in a job and executed it - Works fine.
On the production server- If I execute the package through DTEXECUI, it works fine. But when I try executing it through a job- the job fails and it gives me following error:
Description: The external metadata column collection is out of synchronization with the data source columns. The "external metadata column "T_FieldName" (82)" needs to be removed from the external metadata column collection....
What I don't understand is, why are there no errors displayed when I execute the package through DTEXECUI.
Can anyone help me to resolve this issue.
Thanks.

I'd like to figure out how to use the @FieldDescription table below as an intermediate table between the @SourceData and @Stops data.
declare @Stop table (StopId int, UserField varchar(20))
declare @FieldDescription table (Label varchar(10), ColumnName varchar(10))
declare @UpdateSource table (HasPathway varchar(10))
insert into @Stop (StopId, UserField)
values (1, 'Yes')
[code]...
I want to update @Stop.UserField with thevalue from @UpdateSource where @UpdateSource.HasPathway=@Stop.UserField...but I need to use the @FieldDescription table to determine how to map the columns.

I have a got a package with source as sql table which has got 50 columns. We are using only 10 columns out of this. Recently one column name has changed and thus throws error invalid mapping. When I open the source to do the changes noticed that all the colums are prselected now and also the datatypes got changed to default ( I had changed the datatypes as per my requirement while i developed). So now I had to select required columns from source and redo the datatype changes in advanced editor.Is there any option which doesnt disturb this settings and we just need to correct the mapping alone.

Usually, the XML Source will refresh its metadata when I don't want it to, and will cause me to repair all downstream metadata when it does. This time, I actually want it to refresh, as the schema changes I've made are significant.
Yet, I don't see any "Refresh" button in the XML Source UI. Even clicking "Browse" and browsing to the schema doesn't force a refresh. I've had to change the schema name (it has to be to an existing schema!) then change it back in order to force a refresh.
Is there a "Right" way to do this?
And is there any way to "right-size" the amount of metadata disruption this causes? I was pleased to see that updating a database schema limits the SQL Server Destination to updating only the changed metadata. Yet, any change at all to the XML Schema or XML file will cause all of the XML Source metadata to be invalidated, a process that takes several minutes at 100% cpu usage!

I have an XML file that my XML Source component is accessing. I have noticed that is possible to set a column in the external metadata collection to a certain datatype and the matching output column to a different datatype and this doesn't not generate a warning like it does with other source components (e.g. Flat File Source Adapter).
Try it. Set a column in your external metadata to have a datatype of DT_WSTR. Set the matching output column to DT_UI8. You will NOT get a validation error. I think you should.
This behaviour was noticed on RTM (i.e. no service pack installed) by the way.
I think this is a bug. Anyone agree?

hi, I try to post a new question about metadata refresh...even if i see other thread that work on a similar problem.
I have a ssis package that import an xml huge file (500 mb); These are the main step:
1) generate a XSD file against xml using xsd.exe utility
2) using xml task, make a diff between the old xsd and the new
3) if there are no difference, I start the data flow task that import xml in sql server; otherwise I stop all the task, edit the data flow task, change the xsd reference in advanced editor and then make many "double clik / OK" on every single flow....
The underling idea is that xml file change because some columns are added but these columns are not interesting for my elaboration, so i can ignore this new column and work without mapping it.
What I'm looking for is a way for make, via SSIS, the "double clik / OK" steps....in other words, to update the metadata.
Could anybody suggest me a way? it's a sort of macro, or keyboard recorder...I'm trying to study xml package configuration; is this a good way ?
another way is to give to the end user the task to update metadata; for making this I need to open the package editor (visual studio..:!) in a more confortable environment....For example, is possible to edit the ssis package in ms access? probably i know the answer...
please, help me!
thank tou in advance

I'm having a tad bit of trouble getting output from an asynchronous component that I've written and am looking for some insight.
This component takes in a name string passed from upstream and parses the name components into standardized output fields. I'm using an asynchronous component because if the name string contains two names ("Fred & Wilma Flintstone") I'm outputting one row for Fred and one for Wilma. I've gotten it to run and with debugging have observed what appeared to me to be proper execution, but zero rows are flowing out of it.
In my ProvideComponentProperties method, I add the three fields and there associated metadata to the OutputColumnCollection. Is this method where this should occur? It's before the PrimeOutput method, so I didn't know if I should be creating the output columns in ProcessInput (i.e., after the output buffer is provided by PrimeOutput.)
In ProcessInput, I'm using AddRow for each input row and another if it contains a second name, setting the value for each index using the buffer's SetString method, to no avail. I can observe it to this point, but then don't know what's in that output buffer (if I'm using the wrong buffer index value, etc)
Thanks.

Scenario:
I have 2 identical Analytics cubes, Cube 1 & 2, my reports point to Cube 1, when Cube 2 is refreshed the reports data source is manually repointed to the updated Cube 2. The following day the Cube 1 is refreshed and again the reports data source is edited and repointed back to Cube 1.
This ensures that if a cube build failes the reports aren't down.
To modify the data source I connect to Reporting Services using SSMS go to the Data source folder and manually edit the Data source.
I have looked through the Reporting database in SQL Server but didn't see anything that resembled the connection string for me to edit.
Are the connection strings for the Data sources stored in the Reporting Database ? Where can I find them?
Here is a Microsoft document that gave me the idea. http://www.microsoft.com/technet/prodtechnol/sql/bestpractice/scoqryas.mspx
It talks about changing the connections strings in the Web UI? But doesn't tell you how or point to any docs that do.
Is there a way to automate this and is anyone else running a similar setup.
I appreciate you help
Thanks

SSIS seems to automatically set the metadata type and for "typed" sources like database and XML connections it seems to take whatever the source column datatype is. If you use a cast or convert in the your source SQL query, it will not change the datatype of the metadata. This becomes an issue when doing things like merge joins on data from different sources and the join columns are different types (e.g. a ZipCode in one system is a varchar and it is an int in another system). I've been working around the issue by editing the XML code and changing the datatype there. Is there any way to do this through the GUI?

we run 2008 std edition (I believe r2 on this server, will double check) and I need to find a needle in a haystack.
I am looking at two tables and would like to learn which, if any objects on same db updates these tables. I'd even live with any references to these tables. I already know sql agent is out of the picture. I'm looking for a static approach, not a monitoring one because its possible updates don't occur till month end.
Is there a way in sql server to query the answer to such a question using dmvs or something like dmvs? What if I get bold and want to search all db's on this server for objects that update my two tables even across dbs?
In the mean time, i'll look at scripting all triggers and procs , and doing a search on these table names in the scripts.
I don't know that I've ever seen a way to script all triggers before. Procs I can easily script from the object explorer details. But I'm not sure if in explorer details--> server objects --> triggers does what I hope it does.

New to SSIS...
I created a new package with a source and destination and manually created the output column with data type, etc. Works. The issue is say the table has 200 columns to export.. I dont want to create these by hand. How can I just say export them all to csv format and not have to specify and map each and every column?

I need to perform this task. say I have a table that the columns are dates.
Table months:
[02-2015],[03-2015], [04-2015],[04-2015]....[02-2016].
When the new month comes I want the table to alter the columns automatically instead of manual how we do it now. The new Month table should delete [02-2015] and replace it with [03-2015].
table months:
[03-2015],[04-2015],[05-2015],[06-2015]....[03-2016].

I am stuck on finding a solution to transpose source data from a system via a metadata look-up table into a destination table. I need a method to transpose/pivot the source data into columns (which are by various data-types). The datatypes for each column are listed in a metadata table.
Source Data Table:
Table Name: Source
SrcID AGE City Date
01 32 London 01-01-2013
02 35 Lagos 02-01-2013
03 36 NY 03-01-2013
Metadata Table:
Table Name:Metadata
MetaID Column_Name Column_type
11 AGE col_integer
22 City col_character
33 Date col_date
Destination table:
The source data to be loaded into the destination table(as shown below):
Table Name: Destination
SrcID MetaID col_int col_char col_date
01 11 32 - -
01 22 - London -
01 33 - - 01-01-2013
02 11 35 - -
02 22 - Lagos -
02 33 - - 02-01-2013
03 11 36 - -
03 22 - NY -
03 33 - - 03-01-2013

Hi,
I am trying to create a program that transfers tables to flat files.
At this point in time, I have suceeded in created one that creates delimited files.
However, I am now trying to create fixed-width files as you can do with the SSIS designer, but programatically.
Is there a way to programatically determine the width of a column from the source table? I can not seem to find any kind of function or member that stores this information or allows me to retrieve it.
I know what I need to change in order to set a width for a column, but I just don't know how to find the width without just asking the user to provide one.

Hi guys,
I am new to SQL server, but I need to develop a "big" application with it. Here's my application requirements:
1)Create a table, say TableA, in SQL server 7 or 2000 database,say DB1, based on another Oracle database,say DB2, on a remote server. Update TableA based on DB2 every day in some specific time.
2) If new records are inserted into the TableA,some other tables needed to update in DB1. At the same time, an e-mail will send to three receipts.
I have no idea of which function or method I can use to fulfill the requirements. Can any experts here give me some advice, detail explanation would be grateful.
I appreciate any help you provide.

Sql is not a strong point with me so I'm just going to throw this out there. I have a stored procedure that updates the quantity in my 'CartItems' table. Is there a way to have something else happen within the stored procedure that will update another field based on other parts of the record? There is a 'lineTotal' field that I need to equal the 'pounds * itemSell' fields which are both fields within this record.
CREATE PROCEDURE UpdateCartItem(@cartItemID Int,@newQuantity numeric(9))ASUPDATE CartItems Set quantity = @newQuantityWHERE cartItemID = @cartItemIDGO

I'm trying to update (increment)
Company.SumtotalLogons
from CompanyUsers.NumberOfLogons
where CompanyUsers.CompanyID = Company.CompanyID
I'd like to either write a formula (if it is even possible to fire a formula from one table update/insert to increment a field in another table), or a stored procedure that triggers an auto update/append into Company.SumTotalLogons
I know this is possible in access, so i'm wondering how to go about it in ms-sql?
any ideas?

hi e'body:
I have some database tables, and each one of them have a creation_date and modified_date in them. I was trying to figure out a way where when a row in one of these tables is changed using Enterprise Manager (Database -> Tables -> select table -> right click -> select all rows -> change a field in a row inside a table), is there a way apart from triggers, such that the "modified_date" column for that row get changed to 'getdate()' (rather picks up the current datetime).
thanks in advance.

On Sql Server 2005 Standard if I insert a new row into SomeTable that has a full-text index:
insert SomeTable(keywords)values('this is a test')
and then query:
SELECT * FROM Message WHERE Contains(keywords, ' "test" ');
I get the expected rows all rows that have "test" in the keyword.
On Sql Server 2005 Express new rows are not returned unless I rebuild the catalog.
Is this a known limitation of Express?

I need to create an Bulk upload utility using ASP.Net and SQL Server. Below is the process for the uploads -
Excel Template wherein user will enter the details. A Tab-delimited output file will be generated using the VBA.
There are 2 tables - one is Temp Table which is replica of the the final table and second is the final table
Using File.OpenText(filePath).ReadLine() - All the Rows from the tab delimited data file will be inserted into DataTable.
using SQLBulkCopy the tab-delimited data file data will be inserted into the Temp Table.
Data will be validated based on the data inserted in the temp table. If the data as errors then the temp table will be cleared else the data will be inserted from the temp table to the final table.
My Issue is that in both the tables there is a column (Name : PeopleKey (Int PrimaryKey)). If the user enters Alphabetic value then the Bulk Utility is failing. Below are the two options in my mind -
1. I can change the DataType in Temp table from int to VARCHAR. So, the data can be inserted at first and then I can validate and get the data corrected. But i am not sure whether it is the right way to fix issue as the source and target tables columns are different.
2. When the data in inserted into the Datatable by following Step 3. So, once the data in inserted into DataTable then i can validate there. Thus the source and target tables Datatype will be same.

Hi:
I use a SSIS package to loop thro a folder and load data from multiple excel files to a SQL2005 table. Works fine except when an excel has a missing col.
Col names in xls are always a subset of col names in the table. The missing cols are random, else I would just have made another package:-)
Once a missing column is found, I get runtime and design time errors, and metadata problems. How can a get SSIS to ignore missing columns?
TIA
