Wrong Evaluation Of A Variable With Expression In Case It Is Used Simultaneously By Several Tasks
Aug 22, 2007
Hi guys,
I have experienced problem while trying to use variable with expression based on several other variables in tasks running parallel.
The details are as following:
There is a SSIS package with simple Control flow: one Script Task which actually do nothing and two Execute Process Tasks, they run after Script Task in parallel. Then there are three simple (EvaluateAsExpression = False) string variables ServerName, Folder and JobNumber with values ServerName = €œ\test€?, Folder = €œtest€? and JobNumber = €œ12345€?. And there is one variable FullPath with expression @[User:: ServerName] + "\" + @[User::Folder] + "_" + @[User::JobNumber]. All the variables are of the Package scope. Then in Execute Process Tasks I have similar expressions based on FullPath variable: Execute Process Task 1 has expression @[User::FullPath] + "\date.bat" and Execute Process Task 2 has @[User::FullPath] + "\time.bat" one. As you understand these expressions define what exactly task should execute.
Then I€™m going to execute package from command line so appropriate XML configuration file has been created. The file contains following values for variables described above: ServerName = €œ\LiveServer€?, Folder = €œJob€? and JobNumber = €œ33091€?.
After series of consequent executions I have got following log file:
€¦ Execute Process Task 1€¦ Executing the process €œ\LiveServerJob_33091date.bat€?
€¦ Execute Process Task 2€¦ Executing the process €œ\Test est_12345 ime.bat€?
€¦ Execute Process Task 1€¦ Executing the process €œ\Test est_12345date.bat€?
€¦ Execute Process Task 2€¦ Executing the process €œ\LiveServerJob_33091 ime.bat€?
€¦ Execute Process Task 1€¦ Executing the process €œ\LiveServerJob_33091date.bat€?
€¦ Execute Process Task 2€¦ Executing the process €œ\Test est_12345 ime.bat€?
€¦ Execute Process Task 1€¦ Executing the process €œ\LiveServerJob_33091date.bat€?
€¦ Execute Process Task 2€¦ Executing the process €œ\LiveServerJob_33091 ime.bat€?
€¦
As you can see one of Execute Process Tasks usually receive correct value of the expression (based on values of variables from the configuration file) while another - incorrect one (based on €œdefault€? values of variables set directly in package). Sometimes wrong value appears in Task 1, next time in Task 2. Situations when both expressions in tasks evaluated correctly are very rare.
Then if you add some more Execute Process Tasks with similar expressions in the package (for ex. simply by copying existing tasks) you€™ll get a good chance to catch error like this:
OnError,,,Execute Process Task 1,,,8/17/2007 2:07:12 PM,8/17/2007 2:07:12 PM,-1073450774,0x,Reading the variable "User::FullPath" failed with error code 0xC0047084.
OnError,,,Execute Process Task 1,,,8/17/2007 2:07:12 PM,8/17/2007 2:07:12 PM,-1073647613,0x,The expression "@[User::FullPath] + "\time.bat"" on property "Executable" cannot be evaluated. Modify the expression to be valid.
Seems variable with expression FullPath is locked during evaluation by one of the parallel tasks in such a way that another task can€™t read it value correctly. Can someone help me with the issue? Maybe there are some options I missed which could prevent such behavior of application? Please let me know how I can make the package work correctly.

First of all, I get the following error message for one of my packages which uses user variables:
SSIS package "UsageAnalysis.dtsx" starting.
Information: 0x4004300A at Perform xmlState Shredding, DTS.Pipeline: Validation phase is beginning.
Information: 0x4004300A at Update Analysis Table, DTS.Pipeline: Validation phase is beginning.
Information: 0x4004300A at Update Analysis Table, DTS.Pipeline: Validation phase is beginning.
Error: 0xC001700E at UsageAnalysis: A truncation occurred during evaluation of the expression.
Error: 0xC0019004 at UsageAnalysis: The expression for variable "GetAnalysisData" failed evaluation. There was an error in the expression.
Error: 0xC02020E9 at Update Analysis Table, UsageAnalysis Source [1]: Accessing variable "User::GetAnalysisData" failed with error code 0xC001700E.
Error: 0xC0024107 at Update Analysis Table: There were errors during task validation.
Warning: 0x80019002 at Usage Analysis Process: SSIS Warning Code DTS_W_MAXIMUMERRORCOUNTREACHED. The Execution method succeeded, but the number of errors raised (5) 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 "UsageAnalysis.dtsx" finished: Failure.
Now my package has the following variables:
GetMaxUsageID: scope package level, type string, statement SELECT MAX(UsageID) AS MaxUsageID FROM XX.XXX
MaxUsageID: scope package level, type int32, default value 0, value get assigned from the following statement executed from sql task that runs GetMaxUsageID variable as above
GetAnalysisData: scope package level, type string, Evaluate as Expression
"SELECT * FROM dbo.UsageAnalysis WHERE UsageID > " + (DT_STR, 8, 1252) @[User::MaxUsageID]
The package has worked fine until MaxUsageID value reached to 10,00,000 and since then I have been getting above mentioned error message. The problematic step is related to Data Flow task where I use GetAnalysisData. I have tried replacing user variable with literal as follows
"SELECT * FROM dbo.UsageAnalysis WHERE UsageID > 1000000"
the error message stays the same. Please note that package has worked fine before and it still works ok if I don't use user variables. Obviously, some of you would see eliminating user variables as workaround but I would appreciate if cause of that error message could be investigated.
Thanks,
Asaf

Hi I am trying to do something like the following:
DECLARE @Operator varchar(1)
DECLARE @Rate float
DECLARE @Quantity float
DECLARE @Converted float
SET @Quantity = 6
SET @Operator = '/'
SET @Rate = 2
SET @Converted = 0
@Converted = (@Quantity substituteTheValueOfThis(@Operator) @Rate)
PRINT @Converted
so that the output would be 3
The reason I need to do it like this is that @Operator will change at runtime...
Any suggestions appreciated, I have looked at EXEC sp_execsql but somehow can't get the syntax right.

I think I know the answer to this but thought I'd ask anyway.
I have a conditional split to check a column for null values or empty string values. It looks like this:
(!ISNULL(Ballot)) || (LEN(TRIM(Ballot)) > 0)
My question is: Are both sides of the expression evaluated? My testing says yes, because a Null value causes an error. Is there a way to short circuit the evaluation like the || operator in C# or the (less than elegant, and seemingly threatening) OrElse operator in VB? Whats the best alternative:
A slightly more complex expression that turns a null value into an empty string
A script component
Two conditional splits
Two paths out of one condtional split
I went with the first option, here is the expression I came up with:
LEN(ISNULL(Ballot) ? "" : TRIM(Ballot)) > 0

I have the following query in a user-defined function. It accepts a single string parameter, but for the sake of simplicity, I have substituted actual strings in the query. It basically checks the passed string. If it ends with "Id", it strips off the "Id" and returns the resulting string. If it ends with "Id" followed by a digit, it strips that off and returns the string.
SELECT CASE
WHEN LEN('IncidentViolationId') > 2 AND RIGHT('IncidentViolationId', 2) = 'Id' THEN LEFT('IncidentViolationId', LEN('IncidentViolationId') - 2)
WHEN PATINDEX('%Id[0-9]', 'IncidentViolationId') > 1 THEN LEFT('IncidentViolationId', PATINDEX('%Id[0-9]', 'IncidentViolationId') - 1)
ELSE 'IncidentViolationId' END
This code has worked flawlessly for quite some time and all of a sudden I get "Invalid length parameter passed to left function". I understand why LEFT() would normally fail if I passed it a -1 for the second parameter, but in this scenario, asI understand it, it never should have reached the second WHEN condition since the first one evaluates to true. Why and why all of a sudden?

Hello
When I call ExecuteResultSet(SqlServerCe.ResultSetOptions.Scrollable) I am getting the following error when the data type is Numeric(18, 4):
Expression evaluation caused an overflow. [ Name of function (if known) = ]
The numbers involved are not that big and work fine when ExecuteReader() or ExecuteResultSet(SqlServerCe.ResultSetOptions.None) are called on the same SQL.
Any ideas? Thanks in advance!
Cheers,
Dave
Code:
Private Sub Button2_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button2.Click
Dim errorDescription As String = String.Empty
Dim numericNumber As String = String.Empty
Try
Using sqlCE As New System.Data.SqlServerCe.SqlCeConnection("Data Source = '" & My.Application.Info.DirectoryPath & "MyDatabase.sdf';")
sqlCE.Open()
Dim sqlCECommand As SqlServerCe.SqlCeCommand = sqlCE.CreateCommand()
sqlCECommand.CommandText = "SELECT SUM(MT.TPM_Measure1) AS CurrentAmount FROM BUS_Table MT"
System.Diagnostics.Debug.WriteLine(sqlCECommand.CommandText)
Dim reader As System.Data.IDataReader = Nothing
If RadioButton1.Checked Then
reader = sqlCECommand.ExecuteReader() 'Works fine
ElseIf RadioButton2.Checked Then
reader = sqlCECommand.ExecuteResultSet(SqlServerCe.ResultSetOptions.None) 'Works fine
Else
reader = sqlCECommand.ExecuteResultSet(SqlServerCe.ResultSetOptions.Scrollable) 'Causes the error!
End If
If reader.Read() Then
numericNumber = reader(0).ToString()
End If
reader.Close()
reader.Dispose()
End Using
Catch ex As Exception
errorDescription = ex.Message
Finally
Me.lblError.Text = errorDescription
Me.lblNumeric.Text = numericNumber
End Try
End Sub
TPM_Measure1 datatype is Numeric(18,4)
When the above query works the value is: 4053723.6300

Ive been using SSIS for a month or two and now find I need to create some custom tasks to perform some performance logging. in the the overloaded ProviderComponentProperties section I am trying to create a property which has the same look as the Expressions properties you find elsewhere (Little + on the left and a group of sub properties when expanded).
Ive have played with creating a IDTSCustomPropertyCollection90 collection then adding my sub properties to it but I cant seem to then add my new collection to the ComponentMetaData.CustomPropertiesCollection.
Im assuming the Expressions parameter is a collection added to the properties collection but I cant figure out how. Any help would be much appreciated.

Hi,
I am trying to programmatically execute a package that contains an Execute SQL Task component bound to a variable for its "SqlStatementSource" property (via an expression). The variable is of type String and contains a simple value of "SELECT 1". The Execute SQL Task contains an expression that sets the SqlStatementSource property to the value of this variable.
The package runs fine when I execute it via dtexec or BIDS, but when I attempt to run it via the object model, I receive the following error message:
The result of the expression ""@[User::Sql]"" on property "SqlStatementSource" cannot be written to the property. The expression was evaluated, but cannot be set on the property.
I did a search on this forum and noticed quite a few threads about this same issue, but no explanation/solution. We have quite a few packages that have dynamically constructed SQL statements for Execute SQL Tasks, and they are all failing to run via the object model. Is there something that I am missing?
Thanks,
Vitaly

I have a derived column transformation that inspects two columns for spaces and creates a third column, initialised with either '1' or 'X'.
However the transformation is failing with the error"
Cannot insert the value NULL into column 'TNV-INSERT1'
"
Here's the expression I'm using:
SUBSTRING(rt_tran_inv_text,1,255) != " " ? " X" : SUBSTRING(rt_tnv_narr_cr,1,30) != " " ? " X" : "1"
Neither of the source columns contain nulls. Any idea why it's trying to insert nulls into the new column?

I'm using CTEs to try and get the totals of two different criteria queries that I want to group by Month depending on the associated Inquiry Date. Here is what I have right now;
Code:
;With CTE(total, InitDate) as
(
SELECT count(Inquiry.ID), Inquiry.Date from Inquiry
Inner Join Inquirer on Inquirer.ID = Inquiry.InquirerID_fk
Left Join Transfer on Transfer.TransferInquiryID_fk = Inquiry.ID
WHERE (Inquiry.Date >= '3/1/2012' AND Inquiry.Date <= '9/26/2012' AND Inquiry.Date IS NOT NULL)
AND (Inquirer.Program = 'Res. Referral Coord.')AND TransferInquiryID_fk IS NULL
Group By Inquiry.Date
[code]...
I get 170 for InitCount, but for TransCount I only get 19, not 26. I assume it is with my left outer join statement grouping but I am not sure how I would change this to get the proper counts. All I want to do is group the values together depending on the month they were done in.

Hi Everybody,
I have to generate a seq num and increment it by 1,i used execute sql task and wrote a proc using a variable(out) now this out variable has that value.Now i need to add a extra column to all the records coming in this current batch with the value in the variable.
I know that i can use derived column transformation ,but its not working,giving the following error.
the errors thrown are:
[OLE DB Destination [16]] Error: An OLE DB error has occurred. Error code: 0x80004005. An OLE DB record is available. Source: "Microsoft OLE DB Provider for Oracle" Hresult: 0x80004005 Description: "Unspecified error". An OLE DB record is available. Source: "Microsoft OLE DB Provider for Oracle" Hresult: 0x80004005 Description: "ORA-01779: cannot modify a column which maps to a non key-preserved table ".

[DTS.Pipeline] Error: The ProcessInput method on component "OLE DB Destination" (16) failed with error code 0xC0209029. The identified component returned an error from the ProcessInput method. The error is specific to the component, but the error is fatal and will cause the Data Flow task to stop running.
[DTS.Pipeline] Error: Thread "WorkThread0" has exited with error code 0xC0209029.
[OLE DB Source [1]] Error: The attempt to add a row to the Data Flow task buffer failed with error code 0xC0047020.
[DTS.Pipeline] Error: The PrimeOutput method on component "OLE DB Source" (1) returned error code 0xC02020C4. The component returned a failure code when the pipeline engine called PrimeOutput(). The meaning of the failure code is defined by the component, but the error is fatal and the pipeline stopped executing.
[DTS.Pipeline] Error: Thread "SourceThread0" has exited with error code 0xC0047038.
i have created a variable with scope as package,used that in execute sql task.then using precedence constrains added a data flow task to it.
In the data flow task between the source and destination i placed a derived column transformation.
the execute sql task is running fine,dataflow task is failing.In dataflow task also source and destination is failing but derived column transformation is working.
Am i doing correct.Pls advice.
Regards
Swan

In the Portal1 case expression in the script at the bottom I would liketo replace where the result 1 is returned, with the substring functionreturned as Portal{SUBSTRING(Field1, CHARINDEX('tonep', Field1) + 4, (CHARINDEX('.txt',Field1) - 8) - (CHARINDEX('tonep', Field1) + 4))}However, I am experiencing errors. I think it is because The substringfunction will not return a number as the case expression expects so Imust incorporate cast or convert, but do not know how. Can you help???SELECT portal1 = CASE WHEN len(Field1) > 5 THEN 1 ELSE '' END,SUBSTRING(Field1, CHARINDEX('tonep', Field1) + 4, (CHARINDEX('.txt',Field1) - 8)- (CHARINDEX('tonep', Field1) + 4)) AS portal,Table.*FROM Table

I got the following errors:
Msg 207, Level 16, State 1, Line 9
Invalid column name 'Unit'.
Msg 207, Level 16, State 1, Line 3
Invalid column name 'Unit'.
////////////////////////////////////////////////////////////////////////////////////////////////////////////////
I guess that I had "Unit" (instead of "UnitForConc"), when I executed the sql code last time!!!???
How can I delete the old, wrong CTE that is already in the ChemDatabase of my SSMSE?
Please help and advise.
Thanks in advance,

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)?

ALTER PROCEDURE dbo.TEST_TOTALCALLS
(
@varDate as varchar (255),
@StartDate as datetime,
@EndDate as datetime
)
AS
SELECT
CASE @varDate
WHEN 'Year' Then DATEPART(yy, CALLSTARTTIME)
WHEN 'Quarter' Then DATENAME(qq, CALLSTARTTIME)
WHEN 'Month' Then DATENAME(mm, CALLSTARTTIME)
END,
COUNT(*) as 'Total Calls'
FROM CALLMASTER
WHERE (COMMERCIALS = '1') AND (CALLSTARTTIME >= @StartDate) AND (CALLENDTIME <= @EndDate)
GROUP BY
CASE @varDate
WHEN 'Year' Then DATEPART(yy, CALLSTARTTIME)
WHEN 'Quarter' Then DATENAME(qq, CALLSTARTTIME)
WHEN 'Month' Then DATEPART(mm, CALLSTARTTIME), DATENAME(mm, CALLSTARTTIME) ' <---this part gave me an error, because of the comma,
END
ORDER BY
CASE @varDate
WHEN 'Year' Then DATEPART(yy, CALLSTARTTIME)
WHEN 'Quarter' Then DATENAME(qq, CALLSTARTTIME)
WHEN 'Month' Then DATEPART(mm, CALLSTARTTIME)
END
The month case is giving me an error. I think it has to do with two expressions in one line.
Anyone know how to combine that into 1 expression? or is there away to work around it?
As I would like to display the month as Name, but group and sort by number.
Thx!~

I have to use the Case expression in my query, so I search arround the web and got the following: SELECT title, price, Budget = CASE price WHEN price > 20.00 THEN 'Expensive' WHEN price BETWEEN 10.00 AND 19.99 THEN 'Moderate' WHEN price < 10.00 THEN 'Inexpensive' ELSE 'Unknown' END,FROM titles It should run OK base on my research in the internet. But my SQL Server gave me error: syntax error arround '>'.I did several search and many people can use the ">" sign or "<" sign in the Case expression, but I just can't use it in my SQL Server, I can't even use any boolean expression, I can only use values.can anyone help me out? My SQL Server Version is SQL Server 2000 Sevice Pack 4.Thanks!

Hi,
Maybe this is just totally wrong but this is what I'm trying to do. I want to dynamically insert a value using a CASE expression while executing an external SP from my current SP.
EXEC uspAddMessage @UserId,
CASE @MyAction
WHEN 'DELETE' THEN 'DELETED TRANSACTION.'
WHEN 'APPROVE' THEN 'TRANSACTION APPROVED.'
WHEN 'REJECT' THEN 'TRANSACTION REJECTED.'
END,
@DateStamp
Keep in mind that this is in my stored proc that is doing the processing. I'm calling this common proc when I complete my transactions.
Thanks,
S

I am one very frustrated beginner. If it were not for wonderful information in this forum I would have taken early retirement by now!
Table contains information about new and departing computer and phone users in several departments which we support. This is an existing table which I'm trying to clean up.
The essential part:
CREATE TABLE [dbo].[HelpDesk_NewUser](
[AutoNumber] [int] IDENTITY(1,1) NOT NULL,
[SubmittedDate] [datetime] NULL,
[FirstName] [varchar](100) NOT NULL,
[LastName] [varchar](100) NOT NULL,
[Department] [varchar](100) NOT NULL,
[StartDate] [datetime] NULL,
[DepartDate] [datetime] NULL
[RequestedBy] [varchar](100) NOT NULL,
[UpdatedBy] [varchar](16) NOT NULL,
[CurrentStatus] [varchar](10) NOT NULL ,
[DateCurrentStatus] [datetime] NULL,
[FormType] [varchar](10) NOT NULL,
) ON [PRIMARY]
There can be more than one record per FirstName, LastName. FormType can be N for new or D for departing.
I want to do this for each record:
Read the FormType and Department from the record with the most recent activity (SubmittedDate) for each user
Convert Department to a 4 character department number
Update CurrentStatus with (FormType concatenated with the 4 character dept number) in all records for that user.
I have created another table called UserMostRecent which contains the most recent record for each user.
I have written a query to do this by brute force (read a record, set local variables, update a record), but I would like learn a simpler way to do it. I don't understand the syntax of CASE because it seems to change depending on where it is used.
Here is what I have tried that does not work. Error is "Incorrect syntax near word CASE"
UPDATE HelpDesk_NewUser
SET DateCurrentStatus = b.DateMostRecent,
CurrentStatus = (b.FormType + a.Department
CASE
WHEN 'Roads Department' THEN '3000'
WHEN 'Engineering and Survey Services' THEN '1900'
WHEN 'Waste Management' THEN '8999'
WHEN 'Kern Air Pollution Control District' THEN '9149'
WHEN 'Environmental Health' THEN '4113'
WHEN 'Building Inspection' THEN '2625'
WHEN 'Animal Control' THEN '2760'
WHEN 'Planning Department' THEN '2750'
WHEN 'Community and Economic Development' THEN '5940'
WHEN 'Resource Management Agency' THEN '2730'
WHEN 'Code Compliance' THEN '2620'
WHEN 'Roads Kern Regional Transit' THEN '8998'
END)
FROM HelpDesk_NewUser a JOIN UserMostRecent b
ON (a.LastName = b.LastName and a.FirstName = b.FirstName)
Thank you, forum participants. You are the best!

Is it possible? I have a request to create a stored proc that willdynamically add a range to a WHERE clause based on a numeric value of acomment type. If the incoming comment type request is say 10, thewhere clause needs to be set to IN(10,11,12,13,14,15,16,17,18,19)OR ifa 20 is passed in the clause would read IN(20,21.....)So I was thinking that a CASE expression within the proc would be thebest way to go, but have had no luck in finding an example or any otherrelated information regarding CASE exp in a proc.TIABill

DECLARE @I1 VARCHAR(5),
@I2 VARCHAR(5)
;
WITH cte
AS (SELECT 1 AS i,
'val1' AS j UNION ALL
SELECT 2,
'val2')
[code]....
Why @i1 is null but not @i2 ? I'm trying to assign values after grouping by the column.

I have a scenario where the End User is going to select two parameters. @AgentID and @Location If the End User selects @AgentID parameter, in my WHERE clause, I do not want to check the location condition. By default, the agent knows their location already.
If the End User select @Location parameter, in my WHERE clause, I still want to check the Agent condition.
@AgentID parameter would populate either with "All" or their actual agent# (76754 for example).
@Location parameter would populate either with "All" or their actual location (Birmingham or Bessemer for example)Sample of my current WHERE clause:
WHERE
Â
 gl.ReceiptDate >= @BeginDate and gl.ReceiptDate < DATEADD(D,1,@EndDate)
 AND gl.AgentId = CASE WHEN @AgentID = 'All' THEN gl.AgentID ELSE @AgentID END
 AND gl.Location = @Location
