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.

Integration Services :: Component OLE DB Source Has No Inputs
Nov 12, 2015I have a Data Flow Task. I have one "OLE DB Source" which gets my data from a SQL Server Database. I have a second "OLE DB Source" which uses DATEADD to derive a date qualifier that I would like to use as a date qualifier in my subsequent Excel spreadsheet...opting to use SQL Server and DATEADD rather than messing around with VB syntax to get the previous week date qualifier.I am trying to connect the flow from one OLE DB Source to the next OLE DB Source and get the error..Component OLE DB Source has no inputs, or all of its inputs are already connected to other outputs. You may be able to edit the component to add new inputs to it.Can't I connect two completely different and independent SQL Server queries using "OLE DB Source" within my Data Flow?
Is there any way to store my derived date from my second "OLE DB Source" to a variable so that I cana then use that as my date qualifier within my Excel destination?

May 16, 2008Hi,
I've created my own custom data flow transformation task (using C#) that
will parse a fullname and output the various name parts. In the
ProvideComponentProperties method, I create 5 output columns (prefix, first, middle,
last, and suffix). In the ProcessInput method, I parse the input and add the
name parts to the buffer. The bad thing is that Im making an assumption on
the position of the Full Name input column within the buffer.
I would like the user? to be able to map their "full name" input column to a known Full Name column so I dont have to make any assumptions. This is the first
SSIS task Ive tried to create and I havent been able to find very many
examples online.
Any help is greatly appreciated!
Thank you,

Integration Services :: Data Transformation MMDDYYYY To YYYY-MM-DD
Jul 14, 2015I am working on a SSIS Package and I have to do a data transformation but this one is a but tricky. For example
7/6/2015 is my date and when I apply
SUBSTRING(ColumnName,5,4) + "-" + SUBSTRING(ColumnName,3,1) + "-" + SUBSTRING(ColumnName, 1,1)
I get 2015-6-7 which is good
But then when the date is like 10/12/2015 I would have to modify my code
My question is, Is their anything I can add to the code to make the single digits have a zero before them so I can use the same code throughout. My updated code would then be
SUBSTRING(ColumnName,7,4) + "-" + SUBSTRING(ColumnName,4,2) + "-" + SUBSTRING(ColumnName, 2,1)

Integration Services :: DQS Cleansing Transformation - Can't Deselect Input Columns
Apr 14, 2015In SSIS I use the DQS Cleansing transformation component. I've got a knowledge base (KB) in place and this KB holds various domains and my data source has more input columns than would like to use for a particular clean up operation. I want to use some of the input columns to map against some domains in the KB. It is my understanding that it should be possible to select only the required input columns, but all i can do is select all input columns.

Merge Join With Empty Inputs
May 25, 2006Hi all,
Does anyone have suggestions for ways to deal with the chance that a merge join might receive empty inputs?
I've noticed that when this happens the transformation seems to hang. I changed the MaxBuffersPerInput to zero and this seems to cure the problem but I'm not sure it's the best way to deal with it.
Would it be a good idea to test the row counts with a conditional split before such a join?
Cheers,
Andrew
Multiple Inputs In Merge Join?
Nov 16, 2007hi guys,
just wondering if there's a SSIS component out there some what similar to Merge join but can take up more than two inputs to join.
basically i have a big package with data sources coming from everywhere, they all have a unique column i can join on, so right now, i use merge join for every two sources, then join the output of that to another source so on and so forth. it would be easier if i can just join all of the sources in one component rather than putting a merge join for every single join. is there such a component out there, custom built maybe?
cheers

Nov 3, 2007
I'm doing a data conversion with one of my fields (SUMDWK) from one of the tables that will be used in a merge join. With the new, converted field, I do a look up. From this look up, I want to take a new field FiscalWeekOfYear, and replace the original field, SUMDWK. This is necessary because SUMDWK is one of the sorted fields. In the look up, it is not possible to change the Output Alias. Does anybody know a way around this? Thanks.

Integration Services :: Merge Inner Join Gives Different Output Based On Sort Key?
Sep 23, 2015In the first image as can be seens i have 2 different data sources and then they are being joined using "Merge Inner Join". The "sort" is on BusinessEntityID column of Person table and "Sort1" is on "PersonID" of Customer table. The merge join of these 2 result in 19,119 rows.
On the other hand, if i use single data source and use a query with inner join on tables used in the first image (ie. 2 tables being used in 2 different data sources) as depicted in second image. Also, since merge cannot operate without SortKey i have defined TerritoryID as sort key in the advanced editor. The number of rows i get after this is "10,274". My select query was :
SELECT
P.BusinessEntityID,
P.PersonType,
P.Title,
P.FirstName,
P.MiddleName,
P.LastName,
P.Suffix,
C.TerritoryID
FROM stg.Person AS P
INNER JOIN stg.Customer AS C ON C.CustomerID = P.BusinessEntityID
ORDER BY C.TerritoryID;
According to me, it should have been the same as in first case i am using merge inner join and in second case i am using SELECT query with inner join. Upon drilling down i found that in the first case , my sort keys are BusinessEntityID and PersonID, if i modify this to CustomerID and BusinessEntityID as this is my join condition (in ithe inner join query shown above), i get the desired output. What i was wondering was, how the sort order change the Join Condition?
Integration Services :: Implementing SCD Type 2 Using Merge - Having Both Changing And Historic Attribute

May 7, 2015How do I pass a single column of values from a successful merge join to an EXECUTE SQL statement so it can be used with an "IN" criteria of the WHERE clause? Here's an example of my update statement with two random key values:

Is this even possible in SSIS, or am I better off using a loop and running the update EXECUTE SQL Statement for each individual key value, as in the following example?

UPDATE dbo.MyTable SET MyStatus = 1 WHERE MyPK = "DEF890"
A Custom Component For Use As A VIEW In SSIS- Is It Possible To Create One MERGE Like Component With More Than 2 Inputs
Aug 13, 2007Hi all
I'm into a project which uses a lot of views for joining 2 or more tables. Using the MERGE component in SSIS will be a huge effort coz it only has 2 inputs and I gotta SORT the input too.
Isnt it possible to have a VIEW like component that joins more than 2 tables and DOESNT need sorting??
(I've thought about creating views in database engine but it breaks my data floe in SSIS and is'nt a practical solution)

Reporting Services :: Report Builder 3.0 - Additional Columns Sorted After Values
May 12, 2014I'm somewhat new to report builder and have been trying to recreate a report previously created in an Excel Pivot Table. I'm encountering an issue arranging the data the way it's arranged in Excel.
Specifically, I would like the values column to precede an additional column.
Until I can post pictures I'll have to try and mock it:
COLUMNS
Values
Results (my data I want as a 2nd column)
I can't figure out how to get report builder to do it the same way. Whenever I add the 'Result' data as a column it always appears on top. I'm guessing what I need to do is somehow get result set as a child of the first Static group, but I'm unsure how to do that.
Merge Join Transformation Hangs
Nov 10, 2006I have serached through this forum, and I could not find the solution.
My SSIS data flow is a simple one. Extracting two tables from Oracle using OLE DB Source , join them together using merge join and loading into a table in SQL server by SQL Server Destination.
I haven't gone through this simple procedure because Merge join always hangs there. Down to further investigation, I found one input (randomly one of two inputs) is always stuck. Sometimes the input is empty, sometimes is about half way.
Is there workround to see what is happening there and to fix this problem?

Problem Using Merge Join Transformation In Sql Server 2005(SSIS)
Aug 10, 2006Hi,
I am pretty new to SSIS. I am transferring some rows from 2 source tables to 1 destination table.
The 2 source tables have 1000 rows.They act as the 2 inputs to a merge join transformation where i perform the join between the 2 tables based on a couple of fields. But for some reason the output of the merge join gives me about 1018 rows .Shouldnt the destination also have only 1000 rows?
How do i solve tis problem?
Thanks in advance
