Execute Sql Task Into A ADO Loop

Jul 10, 2007

Hi all,

I got this problem and before post I've read many post similar in the forum (sorry for my english I try to do my best....i'm italian)

This is my scenario.

1) SQL

SELECT

UPPER(SUBSTRING(FileImportazione, 7, 50)) AS str,

Id

FROM Sources

WHERE (TipoImportazione = 0)



This is an SQL task and from this I create a Object variable "ObjDs" on scope package1





2) I introduce a loop (Foreach ADO Enumerator) on my object variable "ObjDs".

Here I mapping two variables "IDsources" and "str" (as you caqn see from my first sql)



Now I set a breakpoint into the beginning of my cicle and really see the dinamic change of the values from "watch" windows.



Now start my problem.

Into this loop I must do "X" operation....but first of all I must Update a table...so I simple SQL TASK...on the dinamic ID of my variable.



Ok, I put a SQL tast into the loop, set SQLsourceType = Variabile, resulset = none, and create an expression like this (SQLstatementsource):

"UPDATE New_pangea.dbo.Sources SET InAggiornamento = "+ (DT_WSTR, 4) @[Utente::IDsources]



If I don't cast (DT_WSTR, 4) I got always an error...

The data types "DT_WSTR" and "DT_I4" are incompatible for binary operator "+". The operand types could not be implicitly cast into compatible types for the operation. To perform this operation, one or both operands need to be explicitly cast with a cast operator.

Attempt to set the result type of binary operation ""UPDATE New_pangea.dbo.Sources SET InAggiornamento = " + @[Utente::IDsources]" failed with error code 0xC0047080.

so I put and validate myexpression.



before my global variable @[Utente::IDsources] change the value to true of EvalutateAsExpression.



Something goes always wrong...When I try debug...this is the error

Errore in Execute SQL Task: Failed to lock variable "UPDATE New_pangea.dbo.Sources SET InAggiornamento = 0" for read access with error 0xC0010001 "The variable cannot be found. This occurs when an attempt is made to retrieve a variable from the Variables collection on a container during execution of the package, and the variable is not there. The variable name may have changed or the variable is not being created.".

Errore in Execute SQL Task: There were errors during task validation.

Hope someone can help me, thanks Alen

Send Mail Task Problem Using A Combination Of ForEach Loop, Recordset Destination, Execute SQL Task And Script Task

Jun 21, 2007

OK. I give up and need help. Hopefully it's something minor ...



I have a dataflow which returns email addresses to a recordset.

I pass this recordset into a ForEachLoop configuring the enumerator as (Foreach ADO Enumerator). I also map the email address as a variable with index 0.



I then have a Execute SQL task which receives this email address as a varchar variable (parameter 0) which I then use in my SQL command to limit the rows returned. I have commented out the where clause and returned all rows regardless of email address to try to troubleshoot this problem. In either event, I then use a resultset to store the query result of type object and result name 0.



I then pass this resultset into a script variable to start parsing the sql rows returned as type object. ( I assume this is the correct way to do this from other prior posts ...).



The script appears to throw an exception at the following line. I assume it's because I'm either not passing in the values properly or the query doesn't return anything. However, I am certain the query works as it executes just fine at the command prompt.



Try

ds = CType(Dts.Variables("VP_EMAIL_RESULTS_RS").Value, DataSet)



My intent is to email the query results to each email address with the following type of data by passing the parsed data from the script to a send mail task. Email works fine and sends out messages but the content is empty. I pass the parsed data as string values to the messagesource and define the messagesourcetype as a variable in the mail task.



part number leadtime

x 5

y 9

....



Does anyone have any idea what I might be doing wrong?

thanks

Execute SQL Task With In A For Each Loop

Apr 24, 2006

hi guys,

i'm trying to do a bulk insert through a t-sql which accepts 3 params.

i frist run a SQL statement to get a list of DB's to update through a SQL task, then i save the output to a variable object. which is been used by the For each loop.

i've done the mapping with the object fine. but i want to call a SQL task within for each loop, and parse the above results as parameters. i tried parsing it as

exec mysp3 @[User::fundid], @[User::dbCode], @[User::subfund]

where fundiid, dbcode and subfund are user defined variables that gets updated by the ado recordset.


this fails with the error msg:

SSIS package "SP test.dtsx" starting.

Error: 0xC002F210 at Execute SQL Task, Execute SQL Task: Executing the query "exec ConnectODBC @[User::fundid], @[User::dbcode], @[User::subfund] failed with the following error: "Incorrect syntax near 'User::fundid'.". Possible failure reasons: Problems with the query, "ResultSet" property not set correctly, parameters not set correctly, or connection not established correctly.

Task failed: Execute SQL Task

Warning: 0x80019002 at Shred the contents of the variable: The Execution method succeeded, but the number of errors raised (1) reached the maximum allowed (1); resulting in failure. This occurs when the number of errors reaches the number specified in MaximumErrorCount. Change the MaximumErrorCount or fix the errors.

SSIS package "SP test.dtsx" finished: Failure.

i also tried

exec mysp3 ?, ?, ?

then mapping the inputs still doesn't work

same thing with

Possible failure reasons: Problems with the query, "ResultSet" property not set correctly, parameters not set correctly, or connection not established correctly.

Execute Package Task In A Loop Works, But...

May 3, 2007

Okay, can someone explain why when I execute children packages within a loop that only a couple of them work?



When I first started this I had Child Package 1 and Child Packge 2 working from the Parent Package 1. It would loop through twice (I had 2 organizations in my outer loop) and pass in the Parent Package variables correctly.



I am using a simple "Foreach Item Enumerator" with a collection of string enumerators that are the Names of the children packages - these are assigned to a variable that is scoped to the outer loop.



Now, when I add a new Child Package 3 and set it up the same as the other 2, when it goes to execute Child Package 3 it fails with the error:



"Error: The connection manager "[My Package Name].dtsx" is not found. A component failed to find the connection manager in the Connections collection. "



What in the world have I done? I was under the assumption that since the first 2 packages worked, that any other packages I added would work the same.

Execute Sql Task Inside For Each Loop Containter

Feb 15, 2008

Hi, I'm trying to loop thru a table and insert records into another table in ssis. So far I have been able to get the data using a execute sql task set up to store the full result set into a variable called data. I then drug a foreach loop container out and selected the foreach ADO enumerator and used my variable data as the ADO object source variable. I then set up a new variable under variable mappings with index 0 to get the collection values. How do I take that variable and update another table using another sql task inside the foreach loop container? Is this possible?

thanks,

SSIS - For Each Loop With Insert In Execute Task Failing

Oct 19, 2015

I have ForEach Loop using Foreach File Enumerator. Within this loop I have SQL Task containing an Insert statement. When I run the Insert statement in query builder the transaction inserts data into a table as expected.

However, when actually running the process I am getting the error message:

Executing the query "INSERT INTO dbo.TEST_TABLE
..." failed with the following error: "Value does not fall within the expected range.". Possible failure reasons: Problems with the query, "ResultSet" property not set correctly, parameters not set correctly, or connection not established correctly.

I currently have the ResultSet to "None" and have defined the parameter I am using. Where the process seems to joke is on my file_Name variable will I am trying to insert only part of the file name.

My insert statement looks as follows:

INSERT INTO dbo.TEST_TABLE
(IID, AN8, File_Type, IB_OB, File_Name, Processed_Flag, ReceiptDateTime)
VALUES
(
'1111',
'123',
'888',

Hi:

I am a R data miner who is new to SQL and SSIS and would appreciate any help.

I wanted to automate the process of creating and processing decision tree models for every county in the Country. I wanted to use the foreach loop for iterate through all the counties. I wanted the foreach enumerator to be used by the XMLA code that creates the model so it would append it to the name of the model and i would get a different model for every county. I am not sure how to have the XMLA code accept foreach loop enumerator.

Any help would be greatly appreciated and if you could direct me to a previously done example that would greatly benefit me.

Using User Defined Function In Execute SQL Task Within Foreach Loop

Jul 19, 2007

hi



I am trying to execute a UDF in an Execute SQL Task within a Foreach loop.

I have an Execute SQL task to get the dataset (Firstname, Lastname, CompanyID) which is going into a full result set called @PendingPar. The Foreach Loop is set to a Foreach ADO Enumerator against @PendingPar and I have created 3 variables at the Foreach Loop scope level called @Firstname (String), @Lastname (String) and @CompanyID (Int32). These are mapped in the Foreach Loop as index 0,1 and 2.



Within the Foreach Loop I have an Execute SQL Task with the sql command



select dbo.udf_GetParTitle (?,?,?)



In the parameter mapping I have Variable Name = User::Firstname Direction = Input Data Type = VARCHAR and Parameter Name = 0, User::Lastname, Input, VARCHAR, 1 and User::CompanyID, Input, VARCHAR,2



Finally the UDF returns a @NewPar value so i have the result set in the execute sql task to Single Row which goes into variable @NewPar. This @newPar will be used later but I cannot get the first bit to work yet.



the error message i get back is



Error: 0xC002F210 at Execute SQL Task 1, Execute SQL Task: Executing the query "select dbo.udf_GetParTitle (?,?,?)

" failed with the following error: "Syntax error, permission violation, or other nonspecific error". Possible failure reasons: Problems with the query, "ResultSet" property not set correctly, parameters not set correctly, or connection not established correctly.

Task failed: Execute SQL Task 1



the initial execute sql task where the dataset is selected works fine but it is within the foreach loop that it fails.



any help gratefully recieved

SSIS: Fpreach Loop Container- Execute SQL Task With ReturnValue Parameter

Jun 9, 2006

Here's the set up:



ForEach Loop Container:

Collection: Foreach File Enumerator

Variable Mappings: Variable = User::DailyFile, Index = 0



Execute SQL Taks:

Connection: OLEDB

ResultSet: None

SQLStatement: EXEC spGetFile ?

ParameterMapping: VariableName = USER::DailyFile, Direction = Input, DataType=VARCHAR, Parameter = 0

This works great it iterates through a file and looks at all the files checks to see if they have been loaded into the db table, if not it loads the file.

My spGetFile has RETURN 1 if a file is loaded and RETURN 0 if the file is not loaded.

Now I add a new variable:

Step 1: add to Foreach Loop Container

ForEach Loop Container Name = Return, Scope = ForEachLoop, Data Type= Int32 Value=0

Step 2: Add to Execute SQL Task:

VariableName = User:Return, Direction = ReturnValue, DataType = Long, ParameterName =1

This produces the following error:

~~"Multiple-step OLE DB operation generated errors. Check each OLE DB status value, if available. No work was done.". Possible failure reasons: Problems with the query, "ResultSet" property not set correctly, parameters not set correctly, or connection not established correctly.~~

I tried with an ADO.Net connection ... works until I add the ReturnValue parameter ...



Any ideas??

Thanks

File Watcher Task (Konessans) Vs For Each Loop Task

Dec 6, 2007



HI, I need to trigger some packages upon existance of specific files in a particular directory. Sound lkike the file watcher task (from SQLIS) would do the job but I am wondering what is the difference of using this tool instead of a for each loop container. I mean, If a file exists in a directory, the for each loop container will detect it. Since the file watcher is not a service, the package containing it needs to ne scheduled on a regular basis for the filewatcher to detect the file, right? So, a for each loop container would do the job? So, waht wouldbe the advantage of using the file watcher task?

Thank you,

Looking For A Way To Refer To A Package Variable Within Any Transact-SQL Code Included In Execute SQL Or Execute T-SQL Task

Apr 19, 2007

I'm looking for a way to refer to a package variable within any
Transact-SQL code included in either an Execute SQL or Execute T-SQL
task. If this can be done, I need to know the technique to use -
whether it's something similar to a parameter placeholder question
mark or something else.


FYI - I've been able to successfully execute Transact-SQL statements
within the Execute SQL task, so I don't think the Execute T-SQL task
is even necessary for this purpose.

Compare Performance (Execute SQL Task Insert And Data Flow Task)

I am using SQL 2005 SSIS. I am joining several large tables and then the move result into another table in the same database.

I would like know which method is faster:


Use Execute SQL Task to insert the result set to the target table

Use the Data Flow Task to insert the result set to the target table. (Use OLE DB source to execute SQL command and then use the SQL destination)
Could you tell me why then other is slower?

Writing Full Result Set From Execute SQL Task Into A File Using Script Task

Mar 28, 2007

In the Control flow tab, I have an Execute SQL Task that outputs full Result set into a variable of an object type. Now how can I write the contents of the Full Result Set into a text file using Script Task. I also want to format the following way while I output into a file:

Column Name 1 : Column Value

Column Name 2: Column Value and so on

I tried writing the contents of the Object Variable into a file, but the file had an output of single word: System.__ComObject.




Code for Writing the Full Result Set into a Text File

Dim RSsqloutput as String = Dts.Variables("objVariable").Value.ToString

Dim strVal as String = "File completed on " & Now() & vbCrLf & "------------------------------------------------------" & vbCrLf

oLogFile.WriteAllText("C:MyFile.txt", strValue)

oLogFile.WriteAllText("C:MyFile.txt", rsSQLOutput)



I went through this link that explains how to write XML Result Set into a File, But this doesn't help as it writes in XML format.

Would you please give me a hint of code how I can go upon.

Execute DTS 2000 Package Task. Mischievous Task??

Hi everyone,

1)The DTS host failed to load or save the package properly
2)The selected package cannot be opened
3)Error HRESULT E_FAIL has been returned from a call to a COM component

But after these messages you can see all the tasks but they haven't name!!

It seem as if RCW mechanism has failed between managed and unmanaged coded-partially.

I don't dare to follow doing more stuff, I don't know if that package is well-loaded or not from there. ?¿

Any guidance or idea about this?

Why DataFlow Task Takes More To Complete Than Doing The Same In Execute SQL Task

An Execute SQL task takes 1 min to run a statement "insert into Mytable select * from view_using_joins"

But a Dataflow task configured to fetch data from the same view_using_joins into MyTable takes hours to do the same.



Could you please explain why is it so ?

Execute Package On A For Each Loop Container

Hi. I am running a package using 'execute package' inside a for each loop file iteration. I have to iterate through some 10,000s of files to ETL source data, a resonably complex package. I want to set going and get some sleep but every 200 files or so I get a memory exhausted error and the task fails. Is there a short easy fix to refresh memory each iteration. If so please let me know. Just ignoring the failure at task level won't refresh the memory, will it?

Loop A Package In Script Task?

Jan 29, 2007

In Dts you can loop a package by creating an Active-X script with something like this ...
"oPackage.Steps("DTSStep_1").ExecutionStatus = DTSStepExecStat_Waiting"
"oPackage.Steps("DTSStep_2").ExecutionStatus = DTSStepScriptResult_DontExecuteTask"

What is the way to do in SSIS? Depending on a condition i want to rerun my package but have not found a smooth way to do it. I guess you can do it in a better way than using the ActiveX Script Task

Slow Web Service Task In Foreach Loop

May 9, 2008



Hi I have created a web service task that sits inside of a foreach loop. The loop is a ado enumerator. This loop is going to loop through about 35,000 records and make 35,000 web service calls.

So far through my testing, I have gotten it to read and write everything correctly, but each call to the web service takes about 1-2 seconds and maxes out the CPU. This would take almost all day for this web service to run at 100% CPU power all day. We want to be able to run this a few times a day or at least once a day.

I have disabled all of the other tasks in the foreach loop so it just calls the web service task and found that it's the web service task that takes up 100% of the CPU and takes 1-2 seconds to run. I have also tried creating a mock web service on the server that just sends back the same mock data, so it's extremely fast, but the Web Service Task still maxes out the CPU and takes 1-2 seconds per call.

I have tried this out on 2 different servers, all with a few gigs of ram they're not using. It seems more like it's a CPU thing, or that the Web Service Task has a high overhead that each time in the loop it takes 1-2 seconds to create the task.

Anyone have any advice?

Thanks,
-Will

For Each Loop And Script Task Not Working Properly

Oct 5, 2007

Hi,

I have a FOR EACH LOOP that loops through a bunch of folders in search of particular filename (including path). That part works fine.

Then, INSIDE the FOR EACH LOOP, I have a script task that evaluates the filename and grabs the date portion of the filename. That part works fine too.

Now, here's my dilemma. If the date portion of the file name IS GREATER THAN the the value of another date in a variable, I want it to load the file into a table using a data flow task.

So, this is what my package looks like:

[ FOR EACH LOOP (Script task --- evaluate the date using an expression (see below) ---> Data flow task) ]

My expression looks like this:

@[User::fileDate] > @[User::maxLoadDate]

You think that this would work, right??

However, after the VERY FIRST iteration of the loop, the script task turns green, then it goes right to the data flow task, which then says that the file name is "", and can't be loaded. (I'm not sure why this is occuring)

My question is, is my logic correct? Can I use an expression inside the for each loop and have it work?
