ForEach Loop - Getting MD5 Hash Of File
Nov 11, 2006
Hi Guys,
I'm importing logs from multiple servers from CSV format into a table. Inside the loop the 1st thing I do is insert the FileName into a table to ensure that I never process the same file twice.
The problem is that multiple servers produce the same filename, so if server A produces Log20061110.csv - when I import the log from server B ( also called Log20061110.csv ) into the table, it of course runs into a problem.
If there was some way for me to get an MD5 Hash of the file as a variable that would be solve my problem.
Does anyone know how I could accomplish that?
Thanks

How do you sort files from the Foreach loop container?
I love this component, except I can't get it to sort by filename.
Nice to know how to sort by timestamps also.

Hi,
I have no "Foreach File Enumerator" oprtion in the Enumerator Property of the Foreach Loop Component.
I have this enumerator in the c:Program FilesMicrosoft SQL Server90DTSForEachEnumerators folder.
Also I check it in the GAC - it does not here. I try to execute gacutil.exe -iF ForEachFileEnumerator.dll, but it is failed with "Failure adding assembly to the cache: The module was expected to contain an assembly manifest." Seems it is not managed enumerator.
Please help me.
Also information on how to regeister unmanaged enumerators are welcome!

Hello,
I want to set up a Foreach loop container to loop through several flat files. I have a connection manager set up for individual flat files. The metadata for the files is all the same. They are fixed width files, and contain sixty five columns.
I didn't see a place in the container properties to configure the metadata of the files. How can a Foreach Loop Container 'know' the metadata of the flat files that I want to loop through?
Thank you for your help!

I have a Foreeach loop container that is looking for all the files in a specified directory. For each file in the directory I need to open the file, extract the contents, and pass the contents as a variable for a stored procedure call.
I was able to loop thru the files in the directory and see each file and store the name to a variable.
I was able to use an XML task to open one file via a file connection that connects to a specified file and store the contents in a variable and then execute the SQL task using the variable.
What I am unable to figure out is how to put the two processes together and get the XML task to open the file by using the variable that contains the filename. If anyone could help I would really appreciate it.
Thanks!

Hi,
I want to do the following with a ssis package:
INPUT:
A table contains 2 columns with data i need. column A=Filename and column B=FileContent
PROCESS:
I need to loop through ea record in the table and retrieve columns A and B. Then for ea column i need to write the Content hold in column B into File hold in column A.
I so far found out, that i need a Execute SQL Task in Control Flow querying the table and get columns A and B into 2 variables, plus a 3rd var holding the object. Then the output goes into a Foreach Loop Container. From this point i don't know how to continue. I tried to put a Data Flow Task inside the Foreach Loop, but couldn't find out how i now get the 2 variables to the Data Flow Task and use them to for the file to be written and the content to be placed in the file.
Is there any example similiar to that so i could learn how to start on that?
Thanks
Danny

Hello
I have a question
How is foreach loop container - foreach ADO enumerator performace in SSIS package compares to use of cursors in stored procedures
Is there any articles comparing them
I understand a lot of factors can affect the performance, however what is expected performance for the foreach ADO enumerator loop for large dataset. What is Microsoft recommendation for that - recommended - not recommended (using large datasets - over million records)
Thank you

I have two queries that seem to be the same, but perform very differently. The first query runs very fast (7000+ records returned in <1 sec.). The execution plan shows that it uses a nested loop with index seeks on both tables.
select *
from t_loadbasic
where ld_nbr in (select ld_nbr from t_tripcombined where comp_date between '11/1/07' and '11/05/07')
The second query is almost the same, save the fact that it uses date variables instead of hard dates. The execution plan shows that it uses a hash match instead of a nested loop with an index scan on the main table (t_loadbasic). This query takes about 12 seconds to run.
declare @startdate datetime
,@enddate datetime
set @startdate = '11/1/07'
set @enddate = '11/5/07'
select *
from t_loadbasic
where ld_nbr in (select ld_nbr from t_tripcombined where comp_date between @startdate and @enddate)
I'm trying to figure out why the database executes these two statements so differently. BTW, I've tried switching the order of the tables. I've tried using joins instead of a subquery. The execution plan seems completely dependant on the use of variables. I can attach the execution plans if necessary.
I apologize if this is too simple a question, but I couldn't find an answer on any forums, web searches or BOL. Thanks in adavance.

I have a foreach loop that is supposed to loop through a recordset, however it doesn't loop. It just repeats the same row, row after row.
I would like to look into the recordset variable but I can't because it is a COM object and the ADODB namespace is not available in the script task.
Any solution to this? anyone experienced anything similar

I need to execute about dozen packages from another package... how do I dynamically pass the dozen package names to the package and execute using foreach loop...?
idea is to store the names of packages in a text file and set the file connection property reading each package names from the text file... in this way I can just configure/edit the text file from time to time, the packages and the units that I want to execute...
Someone please provide me steps to make it work.
Thanks in adv.

Hi,
I'm looping through some query data and doing a Script Task check inside the loop on a datetime field.
If the datetime happens before 10 o'clock:
- Store the data row in Table1
If the datetime happens after 10 o'clock:
- Store the data row in Table2
How can I store the datarow inside the loop without inserting it into a database table?
I need to access the data in the next step after the loop. How can I do this?
Thank you very much!

The foreach loop below runs fine and it sends emails as expected but the SP does not update the Companies table. Any thoughts? How do I cause the SP to execute?
PROCEDURE newdawn.EmailSentDate @CID intAS UPDATE Companies SET Companies.LastEmailDate = (GetDate()) WHERE tblCompanies.C_ID = @CID RETURN
foreach (GridViewRow row in GridView3.Rows) { pstrTo = row.Cells[2].Text; CEmail = row.Cells[2].Text; CName = row.Cells[3].Text; CID = row.Cells[1].Text; CState = TextBox1.Text; CCity = row.Cells[5].Text; CCat = row.Cells[4].Text; CCID = row.Cells[0].Text;
SqlConnection con = new SqlConnection(ConfigurationManager.ConnectionStrings["localhomeexpoConnectionString2"].ConnectionString); SqlCommand cmd = new SqlCommand("EmailSentDate", con); cmd.CommandType = CommandType.StoredProcedure; cmd.Parameters.AddWithValue("@CID", CCID); try { System.String mailServerName = "mail.domain.com";
REST of code sends email to email address found in each row ....it all works find but SP above does not fire.

Help with Looping in a SSIS Package
Scenario:
We have a web app that lets our existing clients insert new locations into a table (Clients) in a SQL Server DB. This table has an Identity column as the PK. This table also has another ID field HBID that is the PK for another table (HLocation) in another Database system (Sybase). The HBID field is given a Default value of €˜1€™ during an insert operation in our (SQL Server) table, Clients. The Sybase database uses a Sequence table for inserting a PK into the table. Whenever our clients insert a new record in Clients (SQL Server), I need to generate a new HBID from the Sequence table in (Sybase), update the HBID in the Clients table (SQL Server) and then finally insert the record with the new HBID into table HLocation (Sybase).
I have devised a SSIS package for this as following: Note all variables are scoped at the Package Level.
Execute SQL Task #1 that drives a For Each Loop with the following properties:
General:
Connection Type: OLE DB
Connection: SQL Server DB
SQL SourceType: Direct Input
SQLStatement:
SELECT COID, HBID, Name, DateCreated
FROM Client
WHERE HBID = '1'
ResultSet: = Full Resultset
Result Set:
Result Name = 0
VariableName = USER::rsClient Variable Type = Object
ForEachLoop with the follwing properties:
Collection:
Foreach ADO Enumerator
ADO Object Source Variable = USER::rsClient
Enumeration Mode = Rows in first table
Variable Mappings:
Variable: Index:
COID 0
HBID 1
Name 2
DateCreated 3
Inside of the ForEachLoop I have another Execute SQL Task to generate a new HBID from Sybase set up as following.
Execute SQL Task #2
Connection Type: OLE DB
Connection: Sybase
SQL SourceType: Direct Input
SQLStatement:
UPDATE Autoinc SET INC_LAST = (INC_LAST+1) WHERE INC_KEY ='HBID';
SELECT INC_LAST AS NewHBID FROM Autoinc WHERE INC_KEY ='HBID'
ResultSet = SingleRow
Result Set:
Result Name = NewHBID
VariableName = USER::NewHBID, VariableType = Int32
Also Inside the ForEachLoop is a Script Task that has all of my variables as ReadWrite = COID, HBID, Name, DateCreated and NewHBID. I concatenate the values in a string a pass the string into a Message Box to make sure they are looping correctly and they are.For example the results might look like the following:
12698, 1, John Doe Trucking, 10/1/2007, 14550
13974, 1, Joe Smith Trucking, 10/1/2007, 14551
10542, 1, Dave Jones Trucking, 10/1/2007, 14552
Etc.
The values 14550 -14552 are the new HBID being generated in the loop.
The problem is that when I try to Update the HBID in the Client table (SQL Server) with another Execute SQL Task I keep getting the same NewHBID number.
In this case 14550 would be updated for every record instead of the next number in the loop.
I have set up Execute SQL Task #3 as follows:
General:
Connection Type: OLE DB
Connection: SQL Server DB
SQL SourceType: Direct Input
SQLStatement:
UPDATE Client
SET HBID = ?
WHERE HBID = '1'(SELECT COID, HBID, Name, DateCreated FROM Client)
ResultSet: = Full ResultSet
Result Set:
Result Name = 0
VariableName = USER::rsNewClient, VariableType = Object
Parameter Mapping:
VariableName USER::NewHBID, Direction = INPUT, DataType = Long
ParameterName = 0
I€™ve tried putting Execute SQL Task #3 inside of the ForEachLoop, connecting it to the output of the ForEachLoop. I€™ve tried setting up a dataflow with a Derived Column using the USER::NewHBID as the Expression.
I still get the same results, 14550 added to every row.
Can any one help or shed some light?
Any and all suggestion will be deeply appreciated!
Thanks !!!

Hi,
Let's say you have a Data Flow Task that connects to a Foreach Loop, looping through the data.
Somewhere inside the Foreach Loop, you set an int variable MyInt to a value.
My question:
Is it possable when each iteration begins to set MyInt to 0?
Thanks in advance.

I'm having a problem where I'm using a Execute SQL Task to retrieve a dataset and storing that in an object variable. Then on success of that execute sql task I use a foreach loop task to go through the dataset and do 2 tasks inside the foreach loop. When I execute this package I have ~12 records in the dataset however when I get to the foreach loop in the 2nd iteration it keeps repeating it. It acts like it is stuck on the second record (tuple) and never goes on. I'm using an ForEach ADO Enumerator in the foreach. I've even set a breakpoint on each iteration and no task fails in side the foreach loop. I'm completely perplexed why it will iterate to the 2nd record but get stuck there in an endless loop. I've tried this on 2 different computers (with different data values) and the same thing happens. Does anyone have any suggestions?

Help,
Trying to through a process together and using the "ForEach Loop" task. When configuring the task and using the ForEach Loop Editor I do not have the "ForEach File Enumerator" in the drop down. Anyone know whats going on or what I need to do to make this appear. I only see 5 selections: ADO, ADO.Net Schema Rowset, Variable, NodeList, and SMO Enumerators. I am also using the SQL 2005 eval with SP1.
Thanks,

Here is what I am attempting to get accomplished. I have an SSIS package that contains a Foreach loop container. This container executes a number of SQL tasks in order: SQL Task 1, SQL Task 2, SQL Task 3.
if the SQL task 1 succeeds it should flow on to SQL Task 2 and 3. This works fine when the SQL tasks do not fail...
In the event of any SQL Task failing control should flow to a send mail task to alert about the failure. Next the Foreach loop container should go to the next enumeration in the Foreach loop container and start the next new SQL task 1. So far I have been able to get the control to flow to the send mail task when a SQL Task fails. What does not work is when one SQL Task fails the entire Foreach loop fails and does not move to the next enumeration. It should only fail the package and move on.
Any help would be appreciated....

All,
I€™m new to SSIS and have a question about foreach loop container.
Basically, I have 4 data flows and each of them has a variable that need be pass on to the next step, each of the variables will call a same stored procedure.
What should I use here? I guess I can use foreach loop container with the stored procedure inside of it, is that right? I tried all day yesterday and cannot make it work.
The foreach loop container did not call the procedure at all. Could someone kindly tell me how to do it?

I have a foreach loop that is processing files in a directory. One of the tasks is the execute sql task that calls a stored proc. If this stored proc returns a certain value then I need to exit the loop and not process any more files. But I have been unable to figure out how to make this happen.
Any help would be greatly appreciated.

I would like your help with the Foreach loop container. Boy, am I having issues with using it for looping through an ADO.NET dataset or what!?!? My control flow has a data flow task that is executing a Data Reader task (creating a .NET dataset for me). Now I go back to the control flow and add a Foreach loop container to loop through each record in my dataset. But which type of the Foreach loop container should I be using? I see an option to use Foreach ADO.NET schema enumerator but not sure how to configure it. Also I used the Foreach ADO option, but setting up variables to go through every column is an absolute pain in the you know what!!?!! I have about 200 columns and I want an easier way to refer to those columns in my transformation phase.
Hope you are able to help me out here.
