Is There A Way To Set A Variable In A Data Flow From A SQL Statement (like In Control Flow)
Jan 12, 2006
I'm currently setting variables at the package level with an ExecuteSQL task. This works fine. However, I'm now starting to think about restartability midway through a package. It would be nice to have the variable(s) needed in a data flow set within the data flow so that I only have to restart that task.
Is there a way to do that using an SQL statement as the source of the value in a data flow?
OR, when using checkpoints will it save variable settings so that they are available when the package is restarted? This would make my issue a moot point.

Hi, All,
I need to pass a parameter from control flow to data flow. The data flow will use this parameter to get data from a Oracle source.
I have an Execute SQL task in control flow to assign value to the Parameter, next step is a data flow which will need take a parameter in the SQL statement to query the Oracle source,
The SQL Looks like this:
select * from ccst_acctsys_account
where to_char(LAST_MODIFIED_DATE, 'YYYYMMDD') >?
THe problem is the OLE DB source Edit doesn€™t have anything for mapping parameter.
Thanks in Advance

I have an Execute SQL Task that returns a Full Rowset from a SQL Server table and assigns it to a variable objRecs. I connect that to a foreach container with an ADO enumerator using objRecs variable and Rows in first table mode. I defined variables and mapped them to the columns.
I tested this by placing a Script task inside the foreach container and displaying the variables in a messagebox.
Now, for each row, I want to write a record to an MS Access table and then update a column back in the original SQL Server table where I retreived data in the Execute SQL task (i have the primary key). If I drop a Data Flow Task inside my foreach container, how do I pass the variables as input to an OLE DB Destination on the Data Flow?
Also, how would I update the original source table where source.id = objRects.id?
Thank you for your assistance. I have spent the day trying to figure this out (and thought it would be simple), but I am just not getting SSIS. Sorry if this has been covered.
Thanks,
Steve

Dear All!
My package has a Data Flow Task. In Data Flow Task, I use a Script Component and a OLE BD Destination to transform data from txt file to database.
Within Data Flow Task, I want to call File System Task to move file to a folder or any Task of "Control Flow" Tab. So, Does SSIS support this task? Please show me if any
Thanks

Hi everyone,
Primary platform is 64 bit cluster.
How to move information allocated in SSIS variables from Data Flow to Control Flow layers??
We've got a SSIS package which load a value into a variable inside a Data Flow. Going back to Control Flow how could we retrive that value again????
Thanks in advance and regards,

Hi all! I recently started working with SSIS and one of the things that is puzzling me the most is what's the best way to go:
A small control flow, with large data flow tasks
A control flow with more, but smaller, data flow tasksAny help will be greatly appreciated.
Thanks,

I want to get the start time of data load and end time after data load and store it in a table which has mapping_id , mapping_name,start_time,end_time.
i use ActiveXScript task to get the start time before data load and store the mapping_id in a global variable,then data flow transformation occurs.
i want to use a global variable to store the mapping id ,so that i can update the end time after data load with that variable.how to do this?
is there any other way, i can get the start and end time of data load (other than the logging information)?

Greetings,
I have run into a problem while creating a simple UDF on SQL Server 2000.
Code Snippet
CREATE FUNCTION [dbo].[GetSectionNum] (@section varchar(4))
RETURNS varchar(2)
AS
BEGIN
DECLARE @sTemp varchar(2),@s char
DECLARE @count int
DECLARE @length int
set @length = LEN(@section)
set @count = 1
WHILE (@count <= @length)
BEGIN
SET @s = SUBSTRING(@section,@count,1)
IF(ISNUMERIC(@s))
BEGIN
SET @sTemp = @sTemp + @s
END
SET @count = @count + 1
END
IF(LEN(@sTemp) = 1)
BEGIN
SET @sTemp = '0' + @sTemp
END
RETURN @sTemp
ENDWhen I perform a syntax check I receive and error about "Error 156: incorrect syntax near keyword 'BEGIN'. I have narrowed the problem to the IF statement inside the While block. If I remove the IF statement the syntax check is successful. This is the first UDF I have written so I'm swimming in uncharted water. Thanks ahead of time for your help.

SSIS Newbie Question:
I have a simple Control Flow setup that checks to see if a particular table exists. If the table does not exists, the table is created in an alternate path, if it does exist, the table is truncated before moving to a file import Data Flow that uses an OLE DB Destination to output the imported data.
My problem is, that I get OLE DB package errors if the table the OLE DB Destination Container references does not exist when I load the package.
How can I over come this issue? I need to be able to dynamically create the table in an earlier step, then use that table to import data into in a later step in the workflow.
Is there a switch I can use to turn off checking in the OLE DB Destination Container so that it will allow me to hook up the table creation step?
Seems like this would be a common task...
Steps:
1. Execute SQL Task to see if the required table exists
2. Use expresions to test a variable to check the results of step 1
3. If table exists, truncate the table and reload it from file in Data Flow using OLE DB Destination
4. If table does not exist, 1st create it, then follow the normal Data Flow
Can someone help me with this?
Signed: Clueless with a deadline approaching...

I recently upgraded to on 2012 SP1 CU5 and have found the SSDT gui for SSIS to be almost unusable. I can't drag or resize items. Any time i try they either automagically shrink to the tiniest possible size, shoot off to some extreme or just shake uncontrollably I didn't have these problems on previous versions (dont remember what It was).
Is there a fix for this?

Hello There:
I am running a data flow within a ForEach loop wherein I am computing a value called QuotaGap. When it is 0 I do not want any further execution of the loop. I am using a Conditional Transform within this dataflow that writes a record to a table only when the QuotaGap is NOT 0. However, I am unable to terminate the execution of the loop as I am still within the dataflow.
Now, the computation of the gap requires a value from another variable called NetPurchases. I tried using an ExecuteSQL task in the control flow but could not figure out how to pass the value of the variable NetPurchases into the select statement to compute the gap. For example, the select statement would read:
select (QuotaUpperLimit - ?) As QuotaGap from <<tablename>>
I tried setting the parameter as an input as well as an output and it did not work.
Then I tried passing the entire SQL as a string within a variable. This does not work either because in order to compute the math QuotaUpperLimit - NetPurchases, both variables need to be integers but then you cannot concatenate integres together, which is what we need to do to create the SQL.
The other reason I am going through these hoops I guess is that I have not figured out a way to set the value of a variable within a data flow. I compute the value for QuotaGap within the dataflow in a ForEach loop but I have no way to pass this result to a variable called QuotaGap without using an ExecuteSQL task or another ForEach Loop.
I have spent hours on this simple issue and so have given up and looking to the good friends in this forum for help.
If what I have stated is not clear please let me know and I will try to clarify things a bit.
Thanks!

hi,
I have an aggregate transformation in a dataflow task.
It has only 1 output value.
I'm trying to assign this value to a user variable, but I can't figure out how to do that.
i can hack something silly together - like write the value to the db, and then get it out, but I there has to be an easier way..
Thanks a lot.!

My package sets a variable in an ExecSQL task. This variable is then used as a parameter in a DataFlow task that follows. Normally everything works just fine. However, sometimes if the package fails inbetween the step that sets the variable and the DataFlow, the default value of the variable is stored in the checkpoint file. (It is not failing in the step that sets the variable) When the package is restarted I can see that the variable is not set to the data value in the database, but rather it has its default (design time) value.
Anyone else see this bug?

I am able to use a custom script task to receive a MSMQ package and save the package contents to a flat file.
I can also use the bulk load task to push the flat file contents into a SQL table.
However, I would like to save the package contents to a variable (done, it works), and then pass that string variable to a data flow task for SQL upload. In other words, I don't see any reason to persist the msmq package contents to disk.
My question is: Which data flow source can I use that will accept a string variable? The string variable will then need to be processed with bulk load or an execute sql task.
Btw, the content of the string variable is a csv style string:
"01001","11/21/2006",15
"01001","11/21/2006",1
"01001","11/21/2006",25
"01001","11/21/2006",3
Thanks,

Hello All,
I have a user variable , say max_id, which retrieves the max id from a primary key column of a table.
now in Data Flow Task, I have a Derived Column where I am creating a new column which will have the values max_id + 1 for the first record, then max_id + 2 for the second record of the derived column and so on..
and then I am mapping this derived column with that primary key column of the table, so that the new id's are different than the old ones which are already in the table, so there wont be any primary key violation.
I cannot make that primary key column as an Identity column.
my question is how do I increment this max_id user variable everytime ?

Hi:
In the derived column transformation editor, I have a Derived column name called FileGroupID. I would like to pass in a value for this column from a variable that I have set earlier in the scope. Can someone let me know, how to write the expression that does that and where do I specifiy that expression. I am thinking its the expression field in the derived column transformation editor. My main question is how to actually write the expression, what is the syntax to pull the variable value? Thanks.

Hi all,
I am creating a customer data flow component for SSIS for use in a package. I've got some custom properties that I am exposing using the supplied advanced editor (no custom property editor here).
Some of my properties are enumerated types, and I have deciphered how to get those properties to show as dropdown lists of their respective enumerations. (For those of you who may be looking as hard as I did as to how to accomplish this, see the end of this post.)
I also have a few properties which request SSIS package variable names - such as an file name variable. However, I can't figure out how to tell the advanced editor that the property is looking for an SSIS variable, so that it can show a dropdown list of package variables, much like virtually any other Microsoft supplied Data Flow component can.
Is there a Type Converter I could specify for those custom properties? Is there another way to instruct SSIS that my custom property is expecting a variable? Or do I need to code a custom UI for editing my Data Flow Task?
To create a dropdown list of values for a custom property that represents an enum, do the following:
1. Create your enum definition, such as "public enum ThisIsMyEnum { one, two }"
2. Create a new class that inherits from TypeConverter, such as "public class MyEnumConverter : TypeConverter"
3. Override "CanConvertFrom", and return true if "sourceType == typeof(string)"
4. Override "CanConvertTo", and return true if "destinationType == typeof(string)"
5. Override "ConvertFrom", and return the enum value (such as "one" or "two" in my example) that corresponds to the string passed in the parameter "value"
6. Override "ConvertTo", and return a string that corresponds to the enum value passed in the parameter "value"
7. Override "GetStandardValuesSupported" and return true
8. Override "GetStandarValuesExclusive" and return true to indicate that ONLY the enum values should be accepted
9. Override "GetStandardValues", and return a new StandardValuesCollection constructed with Enum.GetValues() of your enum, such as "return new StandardValuesCollection(Enum.GetValues(typeof(ThisIsMyEnum)));"
10. Just above your "public enum" declaration, add a "TypeConverter" attribute to link your type converter to your enum, such as "[TypeConverter(typeof(MyEnumConverter))]"
11. In "ProvideComponentProperties", after you've created your custom property like this: "IDTSCustomProperty90 propEnum = ComponentMetaData.CustomPropertyCollection.New()", add another line to specify the TypeConverter property of the property to the full assembly name of your type converter, like so: "propEnum.TypeConverter = typeof(MyEnumConverter).AssemblyQualifiedName;"

Using SSIS to import from Excel to SQL Server.
In Excel they are showing Sale as -ve quantity and purchase as +ve quantity.
The database has quantity always as +ve figure and a separate column "isPurchase" set to true or false depending on whether purchase or sale.
So I need Derived Column to return a bolean (or int) depending whether quantity is positive or negative. I tried each of the following in the Expression but all of them were invalid expressions.
CASE WHEN [TotalQuantity] > 0 THEN 0 ELSE 1 END
If [TotalQuantity] > 0 THEN 1 ELSE 0 END
IIF ([TotalQuantity] > 0, 1,0)
Can anyone help me with correct syntax, or correct Data Flow Transformation if Derived column is wrong.
Thanks

I have following requirement. From OLE-DB source I am getting IDS. Then lookup with some master data. Now I have only matching IDs. Now I need find some filed(say Frequency from some table for each above id). I already write stored procedure for same where I am passing ID as parameter.Which is working fine when I run it SQL server management studio.
Query is sort of
Select field1,fiel2... from table 1 where id = @id
@id is each ID from lookup
Now I want to call this stored procedure in Data flow. I tried it using OLE DB command but it did not return output of stored procudre. I am getting output same what ever I am passing input.
Is there way to do this? In short my requirement is execute parametrized select statement using data flow trasformation component.

The SQL computed is complex enough that I can't see a way to make it a parameterized query. The obvious approach seems to be to compute the SQL in a CONTROL FLOW SCRIPT TASK and then use it to load a variable to set the VARIABLE SOURCE of a CONTROL FLOW EXECUTE SQL TASK.
I see that I can return a resultset to a variable.
But getting the rows of the results into a dataflow is not obvious. I have heard mentione that a Derived Column can do this. I can see using a dummy SCRIPT COMPONENT as DATA SOURCE with nothing in it to then drop into DERIVED COLUMN. But when setting up DERIVED COLUMN I don't see how to pull the columns out of the RESULTSET variable.
If it makes a difference I think the columns of the resultset will always be the same in this scenario.
Maybe this is totally the wrong approach? Any clues would be appreciated.

I have a Data Flow Script Component(Destination Type) and in the properties I have a read/write variable called User::giRowCount
User::giRowCount is populated by a Row Count Component previously in the Data Flow.
After reading http://forums.microsoft.com/MSDN/ShowPost.aspx?PostID=97494&SiteID=1 it is very clear that you can actually only use variables in the PostExecute of a Data Flow Script Component or you will get an error
"Microsoft.SqlServer.Dts.Pipeline.ReadWriteVariablesNotAvailableException: The collection of variables locked for read and write access is not available outside of PostExecute."
What I need to do is actually create a file in the PreExecute and write the number of records = User::giRowCount as second line as part of the header, I also need to parse a read/write variable such as gsFilename to save me hardcoding the path
(Me.Variables.gsFilename.ToString),(Me.Variables.giRowCount.ToString)
-they must go in the PreExecute sub --workarounds please-here is the complete script component that creates a file with header, data and trailer --Is there any workaround

Hi,
I'm trying to implement an incremental data pull (Oracle to SQL) based on Andy's blog:
http://sqlblog.com/blogs/andy_leonard/archive/2007/07/09/ssis-design-pattern-incremental-loads.aspx
My development machine is decent: 1.86 GHz, Intel core 2 CPU, 3 GB of RAM.
However it seems the data flow task gets hung whenever I test the package against the ~6 million row source, as can be seen from these screenshots. I have no memory limitations on the lookup transformation. After the rows have been cached nothing happens. Memory for the dtsdebug process hovers around 1.8 GB and it uses 1-6 percent of CPU resources continuously. I am not using fast load to insert new records into my sql target table. (I am right clicking Sequence Container 3 and executing this container NOT the entire package in the screenshots)

The same package works fine against a similar test table with 150k rows.
http://i248.photobucket.com/albums/gg168/boston_sql92/7.jpg
http://i248.photobucket.com/albums/gg168/boston_sql92/8.jpg
The weird thing is it only takes 24 minutes for a full refresh of the entire source table from Oracle to the SQL target table.
Any hints,advice would be appreciated.

I know I can do this with counters.
However, I was wondering if anyone knows of a SQL equivalent of
"WHILE NOT EOF" as in "do this until you hit the end of the table".
Thanks in advance for any input.

I am having a hard time with what appears to be something simple. I want to import an excel spreadsheet into a table on a daily basis from a command line. I created a package from the Import Wizzard in the SQL Management Studio and saved it. Since I want a clean table each day, my process needs to be create a temp table, import from the Excel file into the temp table. If that is successful, delete the original table and rename the temp table the original name. The point of this process is to provide for a fail-safe if there is some unforseen problem downloading the data on a particular day.
When I run the package, the first thing it does is delete the original table. I know this because the process shows the time that it finished is before anything else has started or finished. The time shown for the completion of the data flow task is about 2 minutes after that time.
This is maddening!!! The one thing I do not want to happen I can not seem to prevent. I have my control flow set on success. Why does it do this?

Is it possible to setup a Control Flow at the solution level rather than at the package level? I'd like to setup a Control Flow that truncates multiple tables in a staging database then runs multiple packages that reloads those tables. Each package has a Control Flow tab that seems to be specific to the package. Is it possible to set something up that governs the execution of multiple packages?
Thanks.

I'm writing my first serious stored procedure.
Essentially I have an incoming file, each line in the file is a record.
The records share the same initial key fields for the first 10 columns, then the field structure varies depending on a rectype and sequence number.
My initial plan was load the keys into fields, and load the remaining data into a long varchar field.
Then the stored procedure would evaluate the Rectype and Seqno of each record and chop up the Varchar accordingly.
So I set up a cursor to read the temporary table, do a fetch into variables, and go to evaluate the variables.
I want to be able to use a CASE statement to evaluate the fields and then perform various logic, but it's giving me fits because it seems like CASE only really works in Select statements, and won't really allow you to do any sort of GOTO logic.
I chopped the following SQL up and put in a rough cut of what I thought I was doing.
DROP TABLE #FOO
GO
CREATE TABLE #FOO (
[planno] [char] (6) COLLATE SQL_Latin1_General_CP1_CI_AS NULL ,
