I have a need to create a SQL database and a table and Insert data into the table from another SQL database . And also to use this newly created database as a oledb source in another dataflow in the same SSIS package. The table and database name are fixed.
I tried using script task to create database and tables. But when I have to insert data , I am not able to give database name in the connection manager as the database is created only in runtime.
I have tried setting ValidExternalMetaData to false, but that doesnt seems to help as well.
Any idea or suggestions on how to accomplish this will be of great help. Thanks
I think you just need two things to make this work:
While developing the package, the database and table will need to exist.
Set DelayValidation to true on the connection manager and dataflow tasks in order to avoid failures with connection tests before they are created.
use a variable to hold the new table name create and populate the using the variable then use the variable name in the source object.

I'm trying to automatically update tables in Azure SQL Database from another SQLDB with Azure Data Factory. At the moment, the only way to update the table Azure SQL Database is to physically select the table you want to update in Azure SQL Database, as shown here:
My configuration to automatically select a table the SQLDB that I want to copy to Azure SQL Database is as follows:
The parameters are as follows:
#concat('SELECT * FROM ',pipeline().parameters.Domain,'.',pipeline().parameters.TableName)
Can someone let me know how to configure my SINK and/or connection to automatically insert the table selected from SOURCE.
My SINK looks like the following:
And my connection looks like the following:

You can use Edit option in the SQL dataset.
Create a dataset parameter for the sink table name. In the SQL sink dataset check the Edit checkbox in it and use the dataset parameter. If you want, you can use dataset parameter for the database name also. Here I have given directly (dbo).
Now in the copy activity sink, you can give the table name dynamically from any pipeline parameter (give your parameter in this case) or any variable using the dynamic content.
Also, enable the Auto create table which will create new table if the table with the given name not exists and if it exists it ignores creation and copies data to it.
My sample result:
I am trying to create a dataflow in SSIS where the source data originates from an excel file and reaches to a temporary staging table in a SQL server where I can add various stored procedures to the data.
The dataflow that I have created stores the data permanently on what is supposed to be the staging area.
I would like to get some ideas on creating the staging table in SQL with the SSIS dataflow.
your question is a bit confusing. I suppose that you are maybe trying to make the data loaded in the table of the staging area temporary without keeping the past loaded data.
If I'm right what you're trying to accomplish is a "full resfresh" data flow.
From your description I assume you alerady have the staging table (so no nedd to CREATE it) but you need to truncate it at every run. You can achive this by using a Execut SQL Task element to the control flow with a TRUNCATE TABLE <YOUR TABLE NAME> in it. The data flow loading the data must be in dependency of this task with the result of truncating your table at every run.
If you need to CREATE a table you can do it in the control flow with the Execute SQL Task (you can execute any kind of query with this task), rember to set correctly the connection manager of the task.
I am new to SSIS so the question might seem simple. What I'm trying to do is to extract data from a source and load it into a new database which should be created in the process (not beforehand). I create that DB using Execute SQL task. However I encounter a problem as I'm unable to connect to that DB using data destination because DB does not exist at that moment.
Can you please help me with ideas how to solve this problem? Or maybe there is any other way how to create the kind of package I described?
I think you need to create db first in your sql server and then point to that db in destination connection. And map the columns with your source query or table with your destination table.
In your requirement you are asking to extract data from suppose Database1 and copy that data in database2. And this should be done during execution of SSIS package.
For this you need to use Execute SQL Task for Destination also.
For example:
Create database Database2;
Insert into Database2.TableName
Select * from Database1.TableName
I was wondering if someone could help me with creating a while loop to iterate through multiple databases(100 databases) and drop/Truncate the tables(Around 60 tables in each database) within those databases.Thank you.
My task is to create an SSIS package to move the data from source database to target database.Data in the destination needs to be truncated as part of the process whenever I run that package the old data need to be truncated and the new data needs to be inserted.
Kindly help.
Thank you.
I am just explain how i would go about this problem.
Hoping the destination and source database,tables are of similar schema.
1) Try to create a table with all the database (Source and destination) details all 60 in a separate database.
2) You need get the database details using execute SQL task from the table and use For Each container for looping the logic of truncate the destination table and then move the data from source database to destination (The data is moved from source database one after other).
3) You will need to use Dynamic SQL and stored procedures for moving the data from source database to destination database (That you must be knowing). or You can use Data flow task too if you don't want to use Stored procedure or Dynamic Queries.
Hope it helps you! :)
In SSIS I have a SQL Task which drops and creates a table T. Then I have a Data Flow task which needs to use T as destination to write data.
The Destination Assistant and the fast-load option needs the table T already present in the database to show it as possible destination.
Maybe I could use SQL Command as data access mode but I don't know how to access the incoming data columns from the stream.
How can I use table T as destination in the data flow task?
Store the tablename inside a package variable, select destination type as Tablename from variable and use it, but make sure to set Delay Validation property to True (change this property in the dataflow task and destination)
Note: when designing package T table must be found in the database to read it's structure in the destination, also if tablename is fixed can achieve this without the use of a variable
instead of drop table T in first sql task, truncate table T and Table t will be a permanently available as destination assistant. Hope this helps
In the SQL Task instead of drop and create, can you just Delete or Truncate the data in table T?
