Deadlock Problem? 3 Way Conditional Split Of Data From One Table To Another Never Completes
Feb 21, 2007
I have a source table which I'm splitting 3 ways based on a column value, but the target is the same OLE DB destination table. One conditional path is to a Multi-Cast two way split to same OLE DB gestination table. The default split is to a flat file for logging unknown record types. For a test I have data for only the 3 column values I want, but I'm having trouble with the process completing. If I pre-filter the data going into the source table by one or two values I can get the process to complete even if one split is to the multicast. If I include all three data types in the source table, I get different results depending on the order in which the conditions are specified - sometimes only two split paths are executed; other times all three are executed, but in some cases only one path of the multicast split is executed. In any case, when the three source data types are used in the test, the process never competes - the pathes are in a yellow condition and never complete.
Am I creating some kind of deadlock situation by having the source data directed to the same target table via 4 splits? Any help you can provide is appreciated. Thanks.

Hi everybody,
I want to load the conditions for a conditional split from a table, so that the bussiness logic can be changed with a simple user interface .
How can I do this?
Best regards

This is probably an easy question, and I just can't find the solution. I've searched extensively, but I am probably just not searching for exactly what I need.
Basically, I have a Conditional Split. What I need to do is for each row coming out of my split, I need to SELECT some data from another database based on one of the fields and then place the data from the DB into a file for later processing.
Seems pretty simple, considering the power of SSIS. Using tools such as OLE DB Command didn't help - the data that comes out of the OLE DB Command is the input data, not the data returned by the command.
How can I do this?
Thank you!

I'm encountering a very peculiar situation when I'm trying to compare source and target data using conditional split. Following is the Data Flow and how I'm trying to achieve this.
Source Data : Col_A (PK)Â Â Â Â Â Col_2
                      1                   100
                      8                   500
Target Data : Col_A (PK)Â Â Â Â Â Col_2
                      1                   100
                      3                   700
                      8                   500
Look-up Target on Col_A to check for existing records. Now we have four columns in Look-up match output: Col_A, Col_B, Lkp_Col_A (Target Col), Lkp_Col_B (Target Col).
Conditional Split: Compare Col_B with Lkp_Col_B
Update target if there is any change in the existing value of Col_B.When I'm running the package for every record in source, the conditional split fails and even when there is no change in Col_B, some of the records (Not all and quite randomly) get updated with the same value. If I run the package for few records, it works absolutely fine.

I am importing the values for field Atype from a .csv file as DT_STR, 13 and I need to fit them into a bit type CType field.
When I write the conditional split ((ISNULL(Atype)?"a":Atype)!=(ISNULL(CType)?"9":CType)) it says that the DT_WSTR and DT_I4 types are incompatible and that I need to explicitly cast with a cast operator. I haven't been able to make it work, how to explicitly cast?

Hello Group
Can somebody guide me on the prefered standards of doing this
I have a Colunm in a table having both NULLS and some data
Ex:
Table 1
Col1 Col2
--------------------------
1 MSDN
2 Forum
3 NULL
4 NULL
5 Condition
6 Split
7 NULL
I want to move the data from this tabel to two different table depending upon the value in Col2
Table2
Col1 Col2
--------------------------
1 MSDN
2 Forum
5 Condition
6 Split
Table 3
Col1 Col2
--------------------------
3 NULL
4 NULL
7 NULL
For doing this I used a simple Conditional Split Task after table 1
First Approach
Output Name; Null Data Condition: ISNULL(Col2)
I routed the output Null Data to Table3 and the default to Table2.
Strangely I see some data in Table3 which is not NULL. That is Table 3 is having a data which is not equal to null in Col2.
I have no clue why will it do that.
Second approach
Output Name: Data, Condition: !(ISNULL(Col2))
I routed the output: Data to Table2 and the default to Table3.
Strangely I see some data in Table3 which is not NULL. That is Table 3 is having a data which is not equal to null in Col2.

I am using a conditional split to evaluate the condition below. It should only send records to my SQL Server database if the PatientZip matches one of the eight below and the PatientCity is not Wichita Falls (you wouldn't believe how bad this is mispelled sometimes). I checked the output table and it has all records for the zipcodes below both matching and non-matching the cityname of Wichita Falls. The table should not have entries for records with the cityname of Wichita Falls. Do I have the code correct or could I have missed something?
LTRIM(PatientCity) != "Wichita Falls" && (PatientZip == "76301" || PatientZip == "76302" || PatientZip == "76305" || PatientZip == "76306" || PatientZip == "76307" || PatientZip == "76308" || PatientZip == "76309" || PatientZip == "76310")

I want to use conditional split on a column that has either a 0 or 1 in order to proceed with the workflow on my conditional split command i have ([colnam])==1 but the transformation still grabs all the data in the table whether the condition is 1 or 0. What could I be doing wrong?

Hi,
In my Excel file I have the columns Col1, Col2. I want to send those records to Sqlserver table only if the Col1 and Col2 is not null.
For this I am using the Conditional Split expression like this: (!ISNULL([Col1])) && (!ISNULL([Col2])). And sending this result to Sqlserver table. But I am not getting any records into the table. But the records col1 and col2 not null exist in Excel file. Is there any thing wrong in my expression?
Thanks in advance

Hello,
I am have an ID column that sometimes contains all numeric characters and sometimes contains all digits. I would like to the records with all digits (0-9) to continue downstream in my Data Flow. I would like the records that contain characters other than digits to be logged to a table.
This sounds like a job for the Conditional Split transformation, but I don't see a way to easily test for a numeric value. For example, I would like to use something like ISNUMERIC([MyIDField]) for testing the values in my Conditional Split, but I don't see a way to do this.
Do I have to create a Derived Column transformation prior to my conditional split that populates a "numeric" ID column for each of my records then test this Derived Column in my Conditional Split? Seems like more work than I would to see for something as simple as testing for a numeric...
TIA...
Brian

In the conditional split transformation,
I am trying to pass the expression like below.
ISNULL(DT_STR(10,1252) [Visit_Date] ) ? "01/01/1990" : [Visit_Date] ! = ISNULL( DT_STR(10,1252)[Visit_Date_Original] ) ? "01/01/1990" : [Visit_Date_original]
but it keeps giving me a syntax error.. what am i doing wrong here?

Hi
Can any one please tell me how do I give multiple conditions in Conditional Split Transformation.
Exp:
I have few columns as
ReturnSUK
TimeSUK
EntitySUK
PeriodSUK
Now the condition should be :
! ISNULL (ReturnSUK) & ! ISNULL (TimeSUK) & ! ISNULL (EntitySUK) &! ISNULL (PeriodSUK)
Please provide me the proper condition for the above mentioned requirement.
Thank you

Hello,
When you´re comparing values in the Condition of the Conditional split, can you assign a value to a variable?
If so, how can you accomplish this?
Thank you.

I have setup a SSIS package that takes a flat file fixed width input, and stores it to two SQL server tables in the same database. The flat file contains two types of records, lets call them Type1 and Type2. The two types of records are formatted differently, and the first character determines what type the record is. I used a conditional split to send record type1 down one path, and type2 down the other. On each of those I use a derived column task to build all the fields and then store to the table with the OLE destination. I put any errors that occur (like truncation) into an error table by setting the "redirected row" feature vs "Fail Component". This all works well and I have no issues.
The dilema is as follows. Type1 is essentially a parent record and the Type2 record is a child. There is a shared primary key / foreign key relationship field. I want errors when processing type1 to cause the associated type2 to also be redirected to the error table vs being inserted.
If anyone has suggestions on how this could be done, reference articles, etc... please let me know.
Thanks.

I have been transfering data from text file to sql databases.
I have a conditional split where i check to if the address has changed for a particular person.If yes i direct to update else i direct to default output which means no change.
when i connect error output of conditional split to a database or union all couple of rows are directed to error output.But i dont understand the reason.How would i be able to know why they r directed to error.
Please let me know.

Good Day All,
I have an interesting situation that I cannot believe is unique. I have a flat file (ragged right) that contains 5 different record types. Each row in the file identifies the record type in the first character. The layout is something like this:
File Header
Group Header (Contains group id number)
Data Item (Contains group id number)
.
.
.
Group Footer (DOES NOT CONTAIN GROUP ID NUMBER)
Group Header (Contains group id number)
Data Item (Contains group id number)
.
.
.
Group Footer (DOES NOT CONTAIN GROUP ID NUMBER)
File Footer
Now I only want to extract data for ONE of the aforementioned groups, however I need the group footer as well because it contains some control totals for the group. The real problem is that the footers do not contain the group id number it goes with. It is a completely positional thing. Silly, yes I know but this particular file layout is an industry standard.
I thought the conditional split would be the way to go. Unfortuately, it seems the conditional split wants to split the entire data set before passing the results down stream rather than processing a single row at a time and passing that row down stream before processing the next one. (Blocking versus streaming I think its called) I could do it in a single god-awful script but I would rather try not to have to code the entire thing.
Any suggestions would be very helpful..
TIA,
Don

If I have 2 input fields to my conditional split, how can I do a compare based on if they are alike. Example, I have 2 IDs, I want to see if the IDs match for a PK/FK relationship, if they match, then output those rows to the conditional's output stream. Do I literally do this or is this not right for the expression? Is there a like statement I should be using instead?
[IDName] == [IDName]
Basically I have 2 OLE DB sources coming in, 2 sets of columns, and both tables behind each OLE DB souce have an ID field to determine the PK/FK relationship. Out of all the records going through from the OLE DB source to the conditional split, I want to output each set of records where the IDs are equal...thuse after my conditional split, I could then take those records and input them into another txt file....and then the process would repeat for the next records in the pipe where IDs are the same...

Hi,
I have the following table in MsAccess
EmployeesA
empId integer,
empName varchar(60),
empAge integer,
empStatus char(1) - can be N,D or S - New, Deleted or Shifted
and the following in Sql2005
EmployeesB
Id smallint,
Name varchar(60),
Age int,
Status char(1) - Bydefault 'N'
I have written a Foreach File package that populates the sql server tables (EmployeesB) from Access(EmployeesA). However i want to check for a condition now.
If empStatus = N in EmployeesA, then insert a new record in EmployeesB
If empStatus = D in EmployeesA, then search for that field in the EmployeesB by passing empname and age and if found, mark the Status field in EmployeesB as 'D'
If empStatus = S in EmployeesA, then search for that field in the EmployeesB by passing empname and age and if found, mark the Status as 'S' in EmployeesB and insert a new row.
How do I do it for each table each row in EmployeesA using a foreach file loop?
Thanks,

Hi All
I am trying to do a simple thing using Conditional Split Task. But I get this error everytime.
[Conditional Split [462]] Error: The expression "ColName1 == "AWM"" on "output "Case 1" (506)" evaluated to NULL, but the "component "Conditional Split" (462)" requires a Boolean results. Modify the error row disposition on the output to treat this result as False (Ignore Failure) or to redirect this row to the error output (Redirect Row). The expression results must be Boolean for a Conditional Split. A NULL expression result is an error.
What I wanted to do is. Split the result result set accoring tro data in Colunm "ColName1". and if the data is AWM then pull that row.
Currently I have NO row for ColName1 that has AWM in it. But still if it didn't find any then all the row must go to default.
Also, when I give a valid name instead of AWM it works.
Please let me know where I am wrong!!!!

I have a package which has a conditional task which directs rows to its respective OLEDB command. The records are sorted from the source system in chronological order. The problem I am experiencing is that some of the operations do not seem to be occurring in the same order. An example of this would be someone inserts a record, deletes the record and reinserts in the record in that order. When we run the package we can see the records are coming down in chronological order but the delete from the split seems to occur after the inserts. Has anyone else experienced this? Is there anything I might be missing to ensure things happen in the order they should? Any advice would be greatly appreciated. Thank you.

Hi,
I have a Conditional Split to FlatFile Destination.
How can I put the result, that goes in the FlatFile Destination, in a variable also (like in Recordset Destination).
Do I have to runs this thing twise (and put the first time in FlatFile Destination and the second time in Recordset Destination)?
Thank you.

Hi,
I'm exporting data to different text files depending on a condition.
My "conditional split" looks like
@[User::Variable0] == 0
@[User::Variable1] == 1
@[User::Variable2] == 2...........etc...
I've about 8 output files from the "conditional split".
For each run, only one condition is valid.
When I run the package with value 0, I need to get only one output file with condition 0's data.
That's working fine but I'm getting all other output files with 0KB, which I don't want.
I'm getting like:
Var0.txt ---------------> 2KB
Var1.txt ---------------> 0KB
Var2.txt ---------------> 0KB
Var3.txt ---------------> 0KB
........... etc.
How can we eliminate those 0 KB files?
Thanks..
Siva.

Hi,
I have a DT_DATE column. I'd like to achieve a conditional split to ignore all records for which the date is below a specific hardcoded date (eg: 2007-03-01).
I'm having a hard time trying to express this using the conditional split transform.
What is the correct syntax to express a DT_DATE literal ?
eg:
[date] < (DT_DATE) "2007-03-01"

Hi all,
I have set up a conditional split task which i want to use with a flat file data source. The flat file consists of multiple rows of data where the first column is an ID. The conditional split is based on the first column value.
What i'd like to know is if in the conditional split once it splits the data can the output be transformed. e.g. If one of the values coming from the flat file requires to be either split up into two values or requires to be passed into a stored procedure to manipulate it, can this be done?
Hope that makes sense.
All help is greatly appreciated, TIA.
Cheers,
Grant

I have a Variable called - UpdateIDs.
I would like to create a conditional split on id's that have no responses and id's that have responses.
The idea is. There is a whole bunch of tables that can be updated if the foreign key is in the no responses id's.
So I have created a data flow. The conditional split is there, but I do not have a "Update Global Variable" Destination source.
Is there away to achieve this.
Basically this is the logic that I am trying to use
Dataflow --> Store Id's into Global Variable --> Data Flow update/insert Tables and Rows where Id in Gloabl Variable.
Is there another way this can be done?
Sorry I am very new to this, and would appreciate any help
Thanks
