Dynamic Destination Table Issue - Can't Find Solution In Archives
Oct 11, 2007
I have searched the archives and haven't found a solution that works.
I started out with a package based on the Excel import wizard and have modified it to include a for each loop for processing more than one Excel source file and also modified it to do some dynamic SQL like dropping and creating the tables with names that are variable based. The package is cabable of processing more than one file, and each file has the same data elements or columns in it, but each file has to go in it's own table. The drop and preperation tasks use string variable SQL that does dynamically create the SQL and runs great. The data flow task and it's OLE destination task (which the wizard did intially create) does not perform as expected. There were some posts in the archives stating that for dynamic destination table names it can be done in the OLE destination but I can't get it to work. I tried using an access mode of table/view name variable and select a variable that is string expression based. But this variable isn't fully populated until run time and so when I'm trying to configure this I get a msg stating the table name object doesn't exist and I can't save the task.
Am I doing something wrong, or trying to do something that wrong way or trying to do something that isn't possible?

How to create a new table dynamically in OLE DB destination.
This is what i am doing
I am reading multiple flat files in loop and saving file name to a variable. Then i have a source script component which read and transforms data .Now how can I push the data to SQL table. I want to create a new table with name saved in a variable. I tried using OLE DB destination and assigning table name from variable. Does'nt work.
Thanks in advance for any insight on how to make this work.

I have a requirement to take xml file, in case the number of column changes, it should not fail the package, rather it should load the data in destination table. Destination table could be altered separately depending on xml schema by the DB team in production.

I have a requirment which i have partly accomplished , but could not get through completely
i have a file which comes in a standard format ending with date and seq number ,
suppose , the file name is abc_yyyymmdd_01 , for first copy , if it is copied more then once the sequence number changes to 02 and 03 and keep going on .
then i need to transform those in to new file comma delimited destination file with a name abc_yyyymmdd,txt and others counting file counting record abc_count_yyyymmdd.txt. and move it to a designated folder. and the source file is then moved to archived folder
what i have taken apprach is
script task select source file --------------------> data flow task------------------------------------------> script task to destination file
dataflow task -------------------------> does count and copy in delimited format
what is happening here is i can accomlish a regular source file convert it to delimited destination file --------> and move it to destination folder with script task .
but cannot work the dynamic pick of a source file.
please advise with your comments or solution you have

Hi all, I'm being driven to distraction by my inability to find a workable solution here, i'll try and lay out my problem as simple as possible:
My application analyses sentence structure, it stores hundreds of thousands of web pages, and stores all the words on those pages sequentially in a database with a primary id, the id of the page the word is from, and the word itself of course.
ie : id , parent_id , word
What i'm trying to do (which already works successfully in both SQL and MySQL) is to retrieve the word immediately before the one I specify and 3 words after the word I specify. Ideally in one union query but i'll accept it if that's too complex and go for two for now.
Because of the sheer size of the database ( millions of keywords ) I can't afford to retrieve every single record and feed off the top results in the application itself.
I've attempted to use subqueries:
SELECT yek FROM child_barrels A WHERE 3 > (SELECT COUNT(*) FROM child_barrels B WHERE A.yek < B.yek) AND id>'" + id + "' AND parent_id='" + parent_id[x] + "' ORDER BY id ASC
SELECT yek FROM child_barrels A WHERE 1 < (SELECT COUNT(*) FROM child_barrels B WHERE A.yek < B.yek) AND id>'" + id + "' AND parent_id='" + parent_id[x] + "' ORDER BY id ASC
These raise an error on the first select statement in the sub query.
(SELECT yek FROM child_barrels WHERE id>'" + id + "' AND parent_id='" + parent_id[x] + "' ORDER BY id ASC LIMIT 3) UNION (SELECT yek FROM child_barrels WHERE id<'" + id + "' AND parent_id='" + parent_id[x] + "' ORDER BY id DESC LIMIT 1)
Above directly is the original MySQL code.
I would appreciate any help available on this, thanks in advance.

Hi,I want to know the optimal solution, to find if all the data was entered. Lets say, Table A (date field) and for a given month, i need that all the days in the given month are present in the Table A. Right now i have different solutions, 1) a stored procedure which loops through all the days in the given month against a select statement on Table A2) a stored procedure, create a temp table which contains all the dates in the given month, and a single select statement using where condition (select * from.... where datefield not in (select * from...))I want to know what is the best solution of these two or any other solution.Thanks

Hi,
Is there anyway to dynamically change the Sql Server Destination? Let's imagine i want the data to go to a table based on a specific parameter like year for example...
Imagine tables like table1_2005, table1_2006 and i want to dinamically change the SQL Server Destination so it would insert 2005 or 2006 and so on....
I can't seem to find that option... It was really a good idea for microsoft to implement Expressions in such components... Dynamics it's all about it :)
Best Regards,

Hello,
I am a beginner for the SSIS and would like to know how to modify the OLDEB Destination connectionString property at run time like using "for each loop container".
My requirement is that I have a single source which would be Sql Server 2005 and my destination is in MS-Access database residing in 100 places. I do not want to manually design in the data flow to these 100 destinations.
I have all the destinations stored in a table and would like to pick these destinations from the table and loop through the same at run time by modifying destination connection string.
I have planned using dts but the for each loop container does not work through as it works with flat file connection manager , but does not go well with OLDEB connection.
Highly appreciate any help in this regard.
Regards

Hi,
I am trying to access from OLE DB source. And based on one of the columns, I need to write the data to a Flat File Destination.
For Example,
CustID, ProductID, Product Name, Product Description
Say I am going to write to a different Flat File for every product. So if there are 10 products in the data. There should be 10 Flat Files. Also the file name should include the Product Name And Product ID.
It is being done in a single Data Flow Task.
Right now the Property Expression for the File Name is which is not working)
Code Snippet@DestFolder + [Data Conversion].ProductID + @TodaysDate + ".txt"
The ProductIDs are in the ascending order. Any help or guidance?

Hello,
What I'm trying to accomplish is to have a variable names "SourceTable" and "DestinationTable". So for each SourceTable, the DestinationTable will have the same columns. All I need is to auto-map these columns between source and destination via code?
Is this possible?

I need to take 5 or 6 select statements to excel. Here are my limitations...
- each of the queries (thankfully) have the same data format
- each of the queries could return more than 65k, so a new worksheet needs to be generated dynamically.
- the names of the excel worksheets need to be custom, but a naming scheme would have to be developed for queries that ran over into multiple worksheets.
What's the smartest way to do this?
I'm having a hard time getting my head around this. I would love any help... I know I'm not breaking any new ground here. I've found pieces of what I'm doing on lots of forums, but never the exact thing. The complexities compound quickly when dealing with dynamic excel worksheets. =)

I have a database app, and we're implementing various data export features using SSIS.
Basically, it's a couple of straight extracts of various recordsets/views, etc. to CSV (flat files) from our SQL Server 2005 database, so I'm creating an SSIS package for each of these datasets.
So far, so good, but my problem comes here: My requirements call for users to select from a list of available columns the fields that they want to include in their exported file. Then, the package should run, but only output the columns specified by the user.
Does anyone have any idea as to the best way to accomplish this? To recap, at design time, I know which columns the users will have to choose from, but at run time, they will specify the columns to export to the flat file.
Any help or guidance here is greatly appreciated

So i need to migrate it in SSIS package compatible to SQL server 2005.
it is migrate also using Data Transformation migration wizard.
But i want to migrate my DTS package programically or by using stored procedure.

Here's what I want to do -
Dynamically load a flat file from a dynamic source table-
The source table metadata is known via the SYSOBJECTS and SYSCOLUMNS tables- I can pull the column names, type and lengths from these tables based on the table name. (my goal is pretty simple- pull data from a table in our database, and save it down to a flat file)
Would this be enough to dynamically create the destination flat file? If so, how do I do it?
Thanks

I recently upgraded to SQL 2005 and after the upgrade, my emailed reports didn't show formating. The email method was Web Archive (MHTML). Embedded images do show up, but inside tables, my bold, background colors, text alignment, table borders are being ignored.
I created a brand new report (VS 2005) and while it works great in the GUI and it works fine running the report from the webserver and exporting as Web Archieve, I still have the same issue that when it is emailed via a subscription, it comes back without formating.
Even more confusing is that the formating of a text box will work as long as it is before the table. If it is along side or below the table, than its formating won't work either.

I created a data flow with complaicated SQL. There is "type" field in the output column.
I would like to created excel files for each "type" value
E.g. If there is 3 "type" values (A, B, C), I would like to create 3 excel files to store type A, type B, and type C data respectively.
Since the number of possibe value of "type" field is various, how can I create the xls destination dynamic and move the correct type to the corresponding excel file?
The conditional split has fixed conditions, it is not suitable for by dynamic number of value
For Loop condition is not a good choice because I need to run the complicated SQL for many time.
Thanks.

Need to know how I can get the dynamic filename created in the FlatFile destination for insert into a package audit table?
Scenario: Have created a package that successfully outputs Dynamiclly named flat files { Format: C:Test’Comms_File_’ + ‘User::FileNumber’+’_’+Date +’.txt’
E.g.: Comms_File_1_20150724.txt, Comms_File_2_20150724.txt etc} using Foreach Loop Container :
* Enumerator Set to: “Foreach ADO Enumerator” with the ADO object source variable selected to identify how many total loop iterations there are i.e. Let’s say 4 thus 4 files to be created
*Variable Mappings : added the User::FileNumber – indicates which file number current loop iteration is i.e. 1,2,3,4
For the DataFlow task have a OLDBSource and a FlatFile Destination where Flat File ConnectionString is set up as:
@[User::Output_Path] + "Comms_File"+ @[User:: FileNumber] +"_" + replace((DT_WSTR, 10) (DT_DBDATE) GETDATE(),"-","")+ ".txt"
All this successfully creates these 4 files:
Comms_File_1_20150724.txt, Comms_File_2_20150724.txt, Comms_File_3_20150724.txt, Comms_File_4_20150724.txt
Now the QUESTION is how do I get these filenames as I need to insert them into a DB Audittable. The audit table looks like this:
CREATE TABLE dbo.MMMAudit
(
AuditID INT IDENTITY(1, 1) NOT NULL,
PackageName VARCHAR(100) NULL,
FileName VARCHAR(100) NULL,
LoadTime DATETIME NULL,
NumberofRecords INT NULL
)
To save the Filename & how many records in each file in our Audit Table, am using an Execute SQL Task and configuring it as this:
Execute SQL Task
Parameter mapping - Mapped the User Variable (RecordsInserted) and System Variable( PackageName) to Insert statement as shown below
SQLStatement: INSERT INTO [dbo].[MMMAudit] (
PackageName,NumerofRecords,LoadTime)
(?,?.GETDATE)
Again this all works terrific & populates the dbo.MMMAudit table as shown below BUT I also need to insert the respsctive file name – How do I do that?
AuditID PackageName FileName NumberOfRecords
1 MMM NULL 12
2 MMM NULL 23
3 MMM NULL 14
4 MMM NULL 1

I am having an issue with the File System Task.
I was wondering if there is a way to 'Move File' with the File System Task inside of a For Each Loop container but to dynamically set the Destination path variable.
Currently, this is what I have:
FileDestinationPath variable - set to C:TestFiles
FileSourcePath variable - set to C:TestFiles
FileNameAndLocation variable - set to blank
For Each Loop Container Iterates through a folder C:TestFiles that has .txt files in it with dates in the file name. Ex: Test_09142006.txt. Sets the file path (fully qualified) to the Variable Mapping FileNameAndLocation.
Script Task (within For Each Loop, first step) Sets the FileDestinationPath to the correct dated folder within C:TestFiles. For example, if the text files I want to move are for the 14th of September, it takes FileDestinationPath and appends the date folder to the end of it. The text files have a date in the file name (test_09142006.txt) and I am picking this apart (from FileNameAndLocation in the For Each Loop) to get the folder date. (dts.Variables(User::FileDestinationPath?).Value = dts.Variables(User::FileDestinationPath?).Value & ? Month & _? & Day & _? & Year & ?) which gives me C:TestFiles 9_14_2006?.
File System Task (within For Each Loop, second step) This is where the action is supposed to occur. I want it to take the FileDestinationPath and move the FileNameAndLocation file (from the For Loop) into this folder for each run.
Now as for my problem. I want this package to run everyday but it has to set the FileDestinationPath variable dynamically according to that days date. Basically, how do I get this to work since I cant hard code the destination path variable from the start? I have the DestinationVariable on the File System Task set to the FileDestinationPath variable, after the script task builds it. However, using FileNameAndLocation as the SourceVariable on my File System Task tells me that the Variable FileNameAndLocation? is used as a source or destination and is empty.?
Let me know if I need to clarify further...I may be missing something very simple. Any help would be greatly appreciated!

Dear all,
i need to design a database table which will store supplier's demand information. 1 supplier will probably have 10000 records and there are posibility that there are 10,000 suppliers. So, in total, the number of records will be 10000 * 10000 = XXXXA LOT XXXX which will be very large number of record to be inserted into a table. So, how can i design an table and structure to cater this scenario? Thanks.

I need to find all uses of special characters in a database. I used the following code to do this:
USE dbName
GO
IF OBJECT_ID('tempdb.dbo.#Results') IS NOT NULL DROP TABLE #Results
GO
[code]...
This will check all tables in the database, but if you want to check specific tables you can uncomment the line in the where clause and specify tables to be checked. The query will return any text fields that have any characters other than letters, numbers or spaces.
This code works fine for me because all the tables in my database have single column primary keys. However I know how much Jeff Moden hates cursors or RBAR queries, so my question is could this have been done by any method other than using a cursor?

VB.NET 2005 Express and SQL Server 2005 Express - NOT saving updates to DB - SOLUTION!
-----------------------------------
The following article is bogus and confusing:
How to: Manage Local Data Files - Setting 'Copy to Output Directory' to 'Do not copy'
http://msdn2.microsoft.com/en-us/library/ms246989.aspx
You must manually copy the database file to the output directory
AFTER setting 'Copy to Output Directory' to 'Do not copy'.
Do not copy
The file is never copied or overwritten by the project system. Because your application creates a dynamic connection string that points to the database file in the output directory, this setting only works for local database files when you manually copy the file yourself.
You must manually copy the database file to the output directory
AFTER setting 'Copy to Output Directory' to 'Do not copy'.
-----------------------------------
The above article is bogus and confusing.
This is rediculous!
This is the most vague and convoluted bunch of nonsince I've ever come accross!
Getting caught out on this issue for the 10th time!
And not being able to find an exact step-by-step solution.
--------------------------
I've tried it and it doesn't work for me.
Please don't try what the article eludes to as I'm still sorting out exactly what is supposed to be happening.
If you have a step-by-step procedure that can be reproduced this properly please PM me.
I would like to test its validity then update this exact post as a solution rather than just another dicussion thread.
Many thanks.
This is the exact procedure I have come up with:
NOTE 1: DO NOT allow VB.net to copy the database into its folders/directorys.
NOTE 2: DO NOT hand copy the database to a folder/directory in your project.
Yes, I know its hard not to do it because you want your project nice and tidy.
I just simply could NOT get it to work.
You should NOT have myData.mdf listed in the Solution Explorer. Ever.
Create a folder for your data following NOTE 2.
Copy your data to that folder. * mine was C:mydatamyData.mdf
Create a NEW project.
Remove any Data Connections. ( no matter what)
Save it.
Data | View Data Sources
Add New Data Source
select NEW CONNECTION ( No Matter what, do it!
Select the database. * again mine was C:mydatamyData.mdf
Answer NO to the question:
Would you like to copy the file to your project and modify the connection?
- NO ( no matter what - ANSWER NO ! - Absolutely NO )
Then select the tables you want in the DataSet.
and Finish.
To Test ----------
From the Solution Explorer | click the table name drop down arrow | select details
Now Drag the table name onto the form.
The form is then populated with a Navigation control
and matching Labels with corresponding Textboxes for each field in the table.
Save it.
1) Run the app.
Add one database record to the database by pressing the Add(+) icon
Just add some quick junk data that you don't mind getting lost if it doesn't save.
YOU MUST CLICK THE SAVE ICON to save the data you just entered.
Now exit the application.
2) Run the app again.
And verify there is one record already there.
Now add a second database record to the database by pressing the Add (+) icon.
NOW add some quick junk data that you WILL intentionally loose.
*** DO NOT *** press the save icon.
Just Exit the app.
3) Again, Run the app.
Verify that the first record is still there.
Verify that the Second record is NOT there.
Its NOT there because you didn't save the data before exiting the app.
Proving that YOU MUST CLICK THE SAVE ICON to save the data you just entered.
Also proving you must add your own code to catch the changes
and ask the user to save the data before exitiing or moving to another record.
As a side note, since vb.net uses detached datasets,
(a copy/snapshot of the dataset in memory and NOT directly linked to the database)
the dataset will reflect all changes made when moving around the detached datasets.
YOU MUT REMEMBER TO SUBMIT YOUR CHANGES TO THE DATABASE TO SAVE THEM.
Otherwise, they will simply be discarded without notice.
Whewh!
I hope this saves me some time the next time I want to start a new database project.
Oh, and uh, for anyone else reading this post.
Thanks,

Hi
My DTS package does nothing special it just pulls in an data from another server (specifying the SQL in a Global V).
This data is then altered using various Stored Procedures.
What would be nice is if the data's destination table could be a #temp table (within tempdb) and then my sps could access it and perform their various operations.
At the moment i cannot get this to work and instead all i can think of is to Create a table within the main working db and insert the data into that and then insert the data into a #temp table and DROP the table i created in the working database.
There must be a better way to achieve this.
Is there any way to copy the data straight to the #temp table i have created?
