Integration Services :: Add Only New Rows To A Destination Table
Jul 22, 2015How do I add only new rows to a destination table (when copying a table from another database every night) ?Every night I am copying a number of tables from one database to another.I only want to insert news rows (that are not in the destination table, but are in the source table) to the destination table.I might normally drop the destination table and just copy over the whole table, but in this case rows can be deleted from the source table, but I want to keep these old rows in the destination table (to maintain history). So I only want to add in rows to the destination table that have been added to the source table since last time.I guess I could copy the whole of the source table to a temporary table in the warehouse, then use a T-SQL merge command to compare and just add new rows to the destination table- but suspect that this is not the best way.

Integration Services :: SSIS Data Transfer Says Rows Copied But Count On Table Is Less?
Sep 18, 2015I've a SSIS 2008 parent/child package solution to manage data transfers between two different data sources, so we can copy multiple tables and capture how many rows were transferred and duration for each transfer. This solution was working fine up until last week, when I made some changes to allow the package to perform a source count using standard SQL determined by an expression, or SQL provided from configuration tables, I also changed the package to Truncate or not the destination table, again controlled by configuration settings in a table. The child packages which perform the data flows have not changed!
The day after the controlling package promotion to live, I saw the bizarre behaviour of the Package log stating all rows transferred, but the actual table counts were not what the log stated, see attached file. The package solution works ok on other servers and was ok in DEV, but there were less tables and rows transferred.Re-running the package gave the same errors, but on some of the same tables and some different ones.
As it is the child packages doing the transfers and nothing has changed in them. I cannot see how the log would be able to say all rows are transferred and yet not all of the rows are actually moved?
Process output - where you can see counts and log Table transfer controller (as txt not dtsx)
An example of the data transfer child packages (as txt not dtsx)When I set the ExecuteOutOfProcess = True the package worked fine, unfortunately, this is not a good solution as SSIS 2008 does not tidy up the Dtshost.exe processes it starts and I'd be left with a memory issue after a very short time, we transfer hundreds of tables each day. ( I could write a .net script in the controlling package to kill the child processes, but that would still have hundreds of processes running before I could end them, as we have three parallel streams to allow a bit better performance.
Integration Services :: Using Rows Returned In Object Variable And Email When Rows Exist
Sep 11, 2015I have a conditional split in an SSIS package - one split is where if rows are returned according to a specific rule, then insert those rows into to a Recordset Destinationm which points to a variable of Object type.
How I can use this variable to email fellow users. For example, what I would like is if ANY rows are returned to the Object variable (1 or more), then I would like to execute an email SP that we have on our server.

Moving Clustered Index On Half Billion Rows?
Feb 29, 2012So I just got an email from Production Support saying an hour and a half downtime is unacceptable to move a half billion rows between 2 partitions because I am moving a clustered index and space is a consideration.
I can not use partition switching because the clustered index is changing.
This is what I am doing...
1. I am creating a new table with the new cluster on a new partiton
2. I am moving the records in 5K set based batches by doing a range search on the existing clustered index on the existing table.
3. I then reapply all of the nonclustered index from the original table to the new one.
4. I do a sp_rename swap out.
The same way I have done this many times before. Is there some new secret special sauce (other than partition switching) I can use?

Integration Services :: Error When Updating MDX Query In Existing Old Package
Jul 21, 2015I have an existing old SSIS Solution that needs to be updated with MDX query. In the query I am using every thing as is but changing only the filter condition. When I try to Preview the data on data flow task, I am getting below error.
Outputs[OLE DB Source Output] references an external data type that cannot be mapped to a Data Flow task data type. The Data Flow task data type DT_WSTR will be used instead.
Package without MDX query update is running fine and no issues. I am using SQL Server 2014 and SSDT 12.0.50318.0 version for your info.
I tried updating SSAS connection string with "Format=Tabular" which was missing earlier and still didn't work.
Integration Services :: Updating SSIS Task Standard Properties Window
May 25, 2015If, in an SSIS package, you put an instance of an 'Execute SQL Task' task in the Control Flow, in the Properties window, you can see the properties of the task, for example CodePage.
If you double click on the task, the Execute SQL Task Editor appears, with several of the properties which are also in the Properties window, including CodePage.
If, in the Editor, you update the value of CodePage, then click OK, the value of CodePage in the Properties window is updated immediately.
I have written a custom SSIS task, which also has the same properties in the Properties window and in the Editor. The Editor also has an OK button. When OK is clicked, the values of the task properties are updated. An example property is FolderToArchive. If I open the Editor, change the value of FolderToArchive and click the OK button, the value of FolderToArchive in the Properties window is NOT immediately updated.
If, however, I select the FolderToArchive field in the Propertiesd window, it is then updated with the value I entered in the Editor.
How do I get my task to update the values in the Properties window, after changing a value in the Editor, when I click the OK button?
I would have thought I would need something like, in pseudo-code,
Task.Parent.PropertiesWindow.Refresh
where task is of type Microsoft.SqlServer.Dts.Runtime.Task and Task.Parent is of type Microsoft.SqlServer.Dts.Runtime.Package.

1 Billion Row Table (Loan Performance)
Mar 28, 2008I will be receiving data from a company called Loan Performance, that has one file/table that will hold 1 billion rows. They send data by period, and I plan to load the data via BCP via NT/DOS scripts. The 1 billion rows represents data for 200+ periods.Are the following design plans feasible1. Partition table by period value, I'm not sure of the max number of partitions per table in 2005, but I think we have periods data back to 1992 and a new one gets created every month, so the possibility of having > 1000 partitions exists. I plan on just pre-creating partitions for future data, instead of dynamically creating when a new period is sent.2. Load data via BCP in DOS shell scripts that will drop index (by partition), BCP in data, and they re-create indexes by partition, is this possible ? and will I see a performance increase as opposed to one huge table (I'm pretty much sure I will). There is usually one periods data present per day, but sometimes the vendor resends all data (would get loaded on weekend).I'm a bit unsure of where to start being I never worked with this amount of data. I worked with partitioning in Oracle a long time ago.I plan on having an 2XQuadCore 2.66Ghz CPU with 32GB of RAM and SQL2005EE 64Bit connected to 1 Terabyte SAN Disk.Thanks all,PMA

Updating Multiple Rows At Once In To SQlServer2005 Table
Sep 25, 2007Hi,
I have a table called "tblProducts" with following fields:-
ProductID(Pk, AutoIncrement), ProductCode(FK), ProdDescr.
So to the above table I have added a new field/column named "ProdLongDescr(varchar, Null)"
So, I need to populate this newly added column with specific values for each row depending on "ProductCode" which is different forevery row. The problem is that I have 25 rows.So instead of Writing 25 individual update scripts, is there a way in which single query will do the same job instead of writing one update query for each row ?. If so can some one guide me how to achieve that OR point to me a good resource.
Below are a couple of Individual update scripts I Wrote. "ProductCode" is different for all 25 rows.
Update tblValAdPackageElement SET ProdLongDescr = 'Slideshows' WHERE ProductCode = 'SLID'
And szElementDescr='Slideshow'
if @@error <> 0
begin
goto ErrPos
end
Update tblValAdPackageElement SET ProdLongDescr = 'CategorySlideshows' WHERE ProductCode = 'SLDC'
And szElementDescr='CategorySlideshow'
if @@error <> 0
begin
goto ErrPos
end

The PrimeOutput method on Flat File Source returned error code 0xC0202091. The component returned a failure code when the pipeline engine called PrimeOutput(). The meaning of the failure code is defined by the component, but the error is fatal and the pipeline stopped executing. There may be error messages posted before this with more information about the failure.
I've tried multiple things to resolve this.. Changing the OutputColumnWidth in the flat file connection manager, checking the file for any irregularites in notepad++ (each line ends as it should with CRLF), the file is encoded in UTF-8 without BOM .

Integration Services :: Generate CSV File Dynamically With A Fixed Amount Of Rows
Jun 5, 2015I need to generate a csv file from another csv file, seems to be simple but let's go the trick thing:
Needs to have maximum 1000 lines, if I reach to this, I need to create another csv and fill that new one.
Exemplifying:
I have a csv file called fileA and this has 2000 lines and another csv called fileB with 1500 lines.
I need to loop a folder and get the fileA, create an output called FileAOutput and start to fill that, if I reach to 1000 lines, I need to create a FileAOutput_2 and fill the other 1000 lines...so I'll go to fileB and do the same thing, but in the second case, I'll have 500 lines in the second output.
Integration Services :: Merge Join Transformation - No Output Rows Redux
Aug 4, 2009I am using SSIS in SQL Server Enterprise 2005. I have two OLE DB data sources from two disparate databases (IBM DB2 and Microsoft SQL Server), some columns from each of which are to be included in the merged output results. I have noted the various requirements in the forum postings with regard to sorting the OLE DB sources and specifying the output source columns as being sorted, as well as the requirement that the join fields in the two sources be close/exact matches. Yet, when I run this in VS, while the work area reflects the expected number of rows being input into the Merge Join transformation, no count is reflected as output from that transformation into the final destination table.Specifically, my two data sources (IBM DB2 and MS SQL) are configured as follows:
IBM DB2 contains an SQL statement that uses Cast operations to create the result columns.and an ORDER BY clause to ensure that the output is sorted by the desired two columns.. The OLE DB source property setting for IsSorted is set to true; the Output Columns folder column definitions for "key_ source_dtsy" and "key_source_dtrt" have their SortKeyPosition properties set to 1 and 2, respectively. Those field are both defined as data type DT_STR, with lengths of 4 and 2, respectively. Below is the Path metadata from the Data Flow Path editor from the path from this source:
IBM DB2 source"Name" "Data Type" "Precision" "Scale" "Length" "Code Page" "Sort Key Position" "Comparison Flags" "Source
Component""ID_CODE" "DT_STR" "0" "0" "10" "1252" "0" "" "Source F0005 User Defined Codes""CODE_DESCR_1" "DT_STR" "0" "0" "30" "1252" "0" "" "Source F0005 User Defined Codes""CODE_DESCR_2" "DT_STR" "0" "0" "30" "1252" "0" "" "Source F0005 User Defined Codes""key_source_dtsy" "DT_STR" "0" "0" "4" "1252" "1" "" "Source F0005 User Defined Codes""key_source_dtrt" "DT_STR" "0" "0" "2" "1252" "2" "" "Source F0005
User Defined Codes:
MS SQL contains an SQL statement that takes the columns as they are in the MS SQL table (no Cast operations needed); it also uses an ORDER BY clause to ensure the output is sorted by the join columns. The OLE DB source property setting for IsSorted is set to true; the Output Columns folder columns for "key_source_dtsy" and "key_source_dtrt" have their SortKeyPosition properties set to 1 and 2, respectively. Those field are both defined as data type DT_STR, with lengths of 4 and 2, respectively. Below is the Path metadata from the Data Flow Path editor from the path from this source:
MS SQL source"Name" "Data Type" "Precision" "Scale" "Length" "Code Page" "Sort Key Position" "Comparison Flags" "Source Component""id_code_name" "DT_I2" "0" "0" "0" "0" "0" "" "Source CodeName in db dwVdFY""key_source_dtsy" "DT_STR" "0" "0" "4" "1252" "1" "" "Source CodeName in db dwVdFY""key_source_dtrt" "DT_STR" "0" "0" "2" "1252" "2" "" "Source CodeName in db dwVdFY"
The Merge Join transformation specifies an INNER JOIN using the columns named "key_source_dtsy" and "key_source_dtrt" from the respective data sources.I know there are alternative ways of accomplishing my intent (Lookup, port MS SQL table to IBM DB2 so join can occur in SELECT statement, etc.; however, I'd like to use this functionality and assume that it should work.

Now, I have final list of records which needs to be delete from access database and new records which are to be inserted into access database.
What do I need to do if I want to delete those duplicate records directly from access database using SSIS. I cannot truncate whole access database and reload. I just have to delete duplicate rows from access db and add new records.
Transact SQL :: Updating Table Rows With Overlapping Dates (extend)
Dec 2, 2015This question is extension from the topic Updating table Rows with overlapping dates: [URL] .....
I am actually having a table as following:
Table Name: PromotionList
Note that the NULL in endDate means no end date or infinite end date.
ID PromotionID StartDate EndDate Flag
1 1 2015-04-05 2015-05-28 0
2 1 2015-04-23 NULL 0
3 2 2015-03-03 2015-05-04 0
4 1 2015-04-23 2015-05-29 0
5 1 2015-01-01 2015-02-02 0
And I would like to produce the following outcome to the same table (using update statement): As what you all observe, it merge all overlapping dates based on same promotion ID by taking the minimum start date and maximum end date. Only the first row of overlapping date is updated to the desired value and the flag value change to 1. For other overlapping value, it will be set to NULL and the flag becomes 2.
Flag = 1, success merge row. Flag = 2, fail row
ID PromotionID StartDate EndDate Flag
1 1 2015-04-05 NULL 1
2 1 NULL NULL 2
3 2 2015-03-03 2015-05-04 1
4 1 NULL NULL 2
5 1 2015-01-01 2015-02-02 1
The second part that I would like to acheive is based on the first table as well. However, this time I would like to merge the date which results in the minimum start date and End Date of the last overlapping rows. Since the End date of the last overlapping rows of promotion ID 1 is row with ID 4 with End Date 2015-05-29, the table will result as follow after update.
ID PromotionID StartDate EndDate Flag
1 1 2015-04-05 2015-05-29 1
2 1 NULL NULL 2
3 2 2015-03-03 2015-05-04 1
4 1 NULL NULL 2
5 1 2015-01-01 2015-02-02 1
Note that above is just sample Data. Actual data might contain thousands of records and hopefully it can be done in single update statement.
Extending from the above question, now two extra columns has been added to the table, which is ShouldDelete and PromotionCategoryID respectively.
Original table:
ID PromotionID StartDate EndDate Flag ShouldDelete PromotionCategoryID
1 1 2015-04-05 2015-05-28 0 Y 1
2 1 2015-04-23 2015-05-29 0 NULL NULL
3 2 2015-03-03 2015-05-04 0 N NULL
4 1 2015-04-23 NULL 0 Y 1
5 1 2015-01-01 2015-02-02 0 NULL NULL
Should Delete can take Y, N and NULL
PromotionCategoryID can take any integer and NULL
Now it should be partition according with promotionid, shoulddelete and promotioncategoryID (these 3 should be same).
By taking the min date and max date of the same group, the following table should be achieve after the table is updated.
Final outcome:
ID PromotionID StartDate EndDate Flag ShouldDelete PromotionCategoryID
1 1 2015-04-05 NULL 1 Y 1
2 1 2015-04-23 2015-05-29 1 NULL NULL
3 2 2015-03-03 2015-05-04 1 N NULL
4 1 NULL NULL 2 Y 1
5 1 2015-01-01 2015-02-02 1 NULL NULL
