Updating Existing Table With Result Of Data Flow

Dec 4, 2007

Hi,

I could use some help on how to save the result of my data-flow in an existing table.

I have created a data flow. I have no trouble storing the result of the flow in a new table. But I'm trying to store the result of my data flow in an existing table. (The flow involves fuzzy grouping, and i would like to store the result in the original table on which the fuzzy grouping was performed). But I cannot get it to work.

I can select the existing table as OLE DB destination. I can write an SQL to manipulate this table, but how do i address the result of the flow in the SQL?

Help is welcome here!

Updating A Table By Both Inserting And Updating In The Data Flow

Sep 21, 2006

I am very new to SQL Server 2005. I have created a package to load data from a flat delimited file to a database table. The initial load has worked. However, in the future, I will have flat files used to update the table. Some of the records will need to be inserted and some will need to update existing rows. I am trying to do this from SSIS. However, I am very lost as to how to do this.

Any suggestions?

Updating A Permanent Table From A Dataset Within The Data Flow

Feb 14, 2007

I have a dataset that was created via a source + lookups + derived columns.

I wish to take this dataset and treat is as a table within a sql statement so that I can update a permanent table with the a specific value within the temp dataset.

In sql this is what I am trying to do:

SELECT COUNT(*) AS Count_of_Employees, DEPT
FROM Employees
GROUP BY DEPT

UPDATE Departments
SET Number_of_Employees = Count_of_Employees
WHERE Dept = dept.

Integration Services :: Check Table For Existing Record Before Data Flow Task

Jun 1, 2015

Using SSIS 2012 (within Visual Studio) on Windows 7.

Before allowing my Data Flow task to fire, I'd like to check the target table (OLE DB Destination) for a specific date value in a specific field. I've seen how the Lookup Task is commonly used to check for dupes before inserting, but I'm not able to use that method because the data value I want to search the table for is contained in a Global Variable (let's say "MyVariableDate").

Is there any way to check for any records in a target table where Date1 = MyVariableDate (i.e. scanning the entire table for any occurrence of MyVariableDate in the Date1 field)?

Metadata On Data Flow Path Not Updating

Jun 18, 2007

I have a data flow task with a single source and destination task. I'm having the source task creating a table from a variable expression and the destination table also created from a variable expression. I'm running this under 3 scenarios in which each scenario has a different source and destination table. They are different in name but close in table structure with the exception of one column being different. The Metadata for the source flow path seems to be "sticky" in that it is not modifying the source table structure in the flow to account for this different column. I'm not sure how to adjust this. Any ideas? I've modified several properties in the task and data flow but nothing seems to make this adjustment in run-time.

Interview Question-How To Identity Existing Data For Updating In SSIS?

Feb 26, 2008

I have met the interview question, I provide answer like the following from my experience. I don't know it is correct or need to supplement. Thank you for help.

Question: How to identity existing data for updating in SSIS?

Answer:
If you have the same key columns such as primary key or business key, you just use them to identify existing records from data source to destination.

If you use different key columns between data source and destination, you can create permanent link table which will store business key for data source and destination, and you can compare records from linking table when you update data.

Updating Of Existing Records

Sep 4, 2007

I have a following problem: I��m importing records from an Access table into a SQL Server Table. I��m using lookup to determine if a record already exists in the SQL Server table and in that case I should update the record if it was modified.

I thought of using OLE DB Destination for new records (done, works fine) and OLE DB Command Transformation to update the modified records. It all works but the thing that bothers me is that my table has approx. 40 columns so my OLE DB Command is very long (update table set col1 = ?, col2 = ?, col3 = ? ��). The other problem is that I��m always updating all the columns even if only one column was modified.

Is there a better way to update the existing records?

Any help is appreciated.

Thanx
Sara

Can I Pull The Data To An Existing Table?

Oct 7, 2005

I am building RDA process between SQL server and SQL server CE. Since when we use the method 'SqlCeRemoteDataAccess.pull()', the data will be pulled down from SQL server to CE server and a new table is created with some addtional columns. As I only intend to pull the data and never push it back to SQL server, if I pull the data down for the second time, there will be an error saying that table is already existing. I wonder whether I can pull the data to an existing table everytime I do the RDA?

How Can Data Flow Destination Be A Temp Table?

Sep 26, 2007

I have a series of data flow tasks that I want to output to a temp table. I've set the data source for RetainSameConnection and the Data Flows are DelayValidation. The OLE DB data source inside the Data Flow works fine, but the data destinations don't offer a # or ## as a target. I've tried every destination that sounds logical, without success.

Any pointers? ... Thanks!

Data Flow OLE DB Command And Table Locking

Jan 7, 2008

Hi all,

I'm just testing an SSIS package and am having issues with dealing with locked records.

my situation is as follows:

my source table is oracle, my destination table is in SQL server. my data flow is a very simple update with a lookup transformation and then two OLEDB commands for update and insert.

On each of the OLEDB commands I have set the "command timeout" to 5 seconds (just for testing purposes). also each OLE DB command has a failure path that outputs to a flat file. I'm expecting that if the destination table/records is/are locked then after 5 seconds the record will be output to the flat file.

so to test this I begin a transaction on the destination table and don't commit it. then I start the SSIS job. it doesn't appear to even get to the OLE DB commands. it appears to stop at the beginning of the data flow task. the output window shows this:

"Information: 0x40043007 at Import from Phoenix, DTS.Pipeline: Pre-Execute phase is beginning."

but it just hangs there indefinately. the progress tab tells me that it get's from the validating stage and past the prepare for execute stage but hangs on pre-execute - 0 percent.

I've put the command timeout = 5 on everything that I can find. I've mucked arround with all the possible "validateExternalMetadata" properties even though I only guessed that it may be the cause. is there anything that I'm missing? where should I look next?

(yes it does work perfectly when there is no transaction locking the target table)

Cheers,
Andrew

Use Newly Created Table In Data Flow Task

Jul 20, 2006

Hello dear Forum,

I guess this should be rather simple to answer but i just don't get how to do this. I just want to import some data from an Access mdb file into a SQL Server 2005 Database.

As I dont want to create all tables in Sql Server 2005 beforehand i'd like to create them out of my SSIS Package. Therefore i use the 'Execute SQL Task' in the control flow before stepping into the dataflow where only a oledb-source and an oledb-destination exist...

VERY simple... My problem is, that i can't select the table from the selectionlist in the oledb-destination because it does not exist before executing the package...

If i create the table by hand just to be able to select it, that does not help. because if everything is set up and then i delete the table (because it will be created by the package anyway) an error occurs before executing the package - in the validation phase:

Package Validation Error: "Invalid object name 'myToBeCreatedTable'".

Can't i create tables on the fly which i use then in my dataflow tasks?

Kind regards,

Wolfgang

Problem Updating Existing Records With Newid()

Apr 23, 2008

I currently have a table called stores. I've just added a uniqueidentifier column called store_guid to the stores table. The table currently has about 500 records in it and now i'm trying to set each store_guid = to a newid(). I've tried using UPDATE stores SET store_guid = newid() . however, that doesn't work because i think it's trying to set each record equal to the same guid using that approach. All i need to do is fill in my new column with new guids. any ideas?
