Global Variable??
Nov 1, 2007
I have several stored procedures and UDFs that have code that convert between GMT timezone and other U.S. timezones.
for example,
to convert from GMT to CT I use this:
@dtmCentral = dateadd(hour, -5,@GMTdtm)
However, come Nov 4th after 2AM, when DST ends, I need to change this to
@dtmCentral = dateadd(hour, -6,@GMTdtm)
Assuming that I can store this -5 or -6 value in a global variable, I want to have a stored procedure that updates it when DST starts and ends.
Is there a better way of doing this other than the option of going through the entire calculations of figuring out whether it's DST or not each time ?
Thanks.

I have a SQL Task that updates running totals on a record inserted using a Data Flow Task. The package runs without error, but the actual row does not calculate the running totals. I suspect that the inserted record is not committed until the package completes and the SQL Task is seeing the previous record as the current. Here is the code in the SQL Task:
DECLARE @DV INT;
SET @DV = (SELECT MAX(DateValue) FROM tblTG);
DECLARE @PV INT;
SET @PV = @DV - 1;
I've not been successful in passing a SSIS global variable to a declared parameter, but is it possible to do this:
DECLARE @DV INT;
SET @DV = ?;
DECLARE @PV INT;
SET @PV = @DV - 1;
I have almost 50 references to these parameters in the query so a substitution would be helpful.

I'm new to SSIS, but have been programming in SQL and ASP.Net for several years. In Visual Studio 2005 Team Edition I've created an SSIS that imports data from a flat file into the database. The original process worked, but did not check the creation date of the import file. I've been asked to add logic that will check that date and verify that it's more recent than a value stored in the database before the import process executes.
Here are the task steps.
[Execute SQL Task] - Run a stored procedure that checks to see if the import is running. If so, stop execution. Otherwise, proceed to the next step.
[Execute SQL Task] - Log an entry to a table indicating that the import has started.
[Script Task] - Get the create date for the current flat file via the reference provided in the file connection manager. Assign that date to a global value (FileCreateDate) and pass it to the next step. This works.
[Execute SQL Task] - Compare this file date with the last file create date in the database. This is where the process breaks. This step depends on 2 variables defined at a global level. The first is FileCreateDate, which gets set in step 3. The second is a global variable named IsNewFile. That variable needs to be set in this step based on what the stored procedure this step calls finds out on the database. Precedence constraints direct behavior to the next proper node according to the TRUE/FALSE setting of IsNewFile.
If IsNewFile is FALSE, direct the process to a step that enters a log entry to a table and conclude execution of the SSIS.
If IsNewFile is TRUE, proceed with the import. There are 5 other subsequent steps that follow this decision, but since those work they are not relevant to this post.
Here is the stored procedure that Step 4 is calling. You can see that I experimented with using and not using the OUTPUT option. I really don't care if it returns the value as an OUTPUT or as a field in a recordset. All I care about is getting that value back from the stored procedure so this node in the decision tree can point the flow in the correct direction.
CREATE PROCEDURE [dbo].[p_CheckImportFileCreateDate]
/*
The SSIS package passes the FileCreateDate parameter to this procedure, which then compares that parameter with the date saved in tbl_ImportFileCreateDate.
If the date is newer (or if there is no date), it updates the field in that table and returns a TRUE IsNewFile bit value in a recordset.
Otherwise it returns a FALSE value in the IsNewFile column.
Example:
exec p_CheckImportFileCreateDate 'GL Account Import', '2/27/2008 9:24 AM', 0
*/
@ProcessName varchar(50)
, @FileCreateDate datetime
, @IsNewFile bit OUTPUT
AS
SET NOCOUNT ON
--DECLARE @IsNewFile bit
DECLARE @CreateDateInTable datetime
SELECT @CreateDateInTable = FileCreateDate FROM tbl_ImportFileCreateDate WHERE ProcessName = @ProcessName
IF EXISTS (SELECT ProcessName FROM tbl_ImportFileCreateDate WHERE ProcessName = @ProcessName)
BEGIN
-- The process exists in tbl_ImportFileCreateDate. Compare the create dates.
IF (@FileCreateDate > @CreateDateInTable)
BEGIN
-- This is a newer file date. Update the table and set @IsNewFile to TRUE.
UPDATE tbl_ImportFileCreateDate
SET FileCreateDate = @FileCreateDate
WHERE ProcessName = @ProcessName
SET @IsNewFile = 1
END
ELSE
BEGIN
-- The file date is the same or older.
SET @IsNewFile = 0
END
END
ELSE
BEGIN
-- This is a new process for tbl_ImportFileCreateDate. Add a record to that table and set @IsNewFile to TRUE.
INSERT INTO tbl_ImportFileCreateDate (ProcessName, FileCreateDate)
VALUES (@ProcessName, @FileCreateDate)
SET @IsNewFile = 1
END
SELECT @IsNewFile
The relevant Global Variables in the package are defined as follows:
Name : Scope : Date Type : Value
FileCreateDate : (Package Name) : DateType : 1/1/2000
IsNewFile : (Package Name) : Boolean : False
Setting the properties in the "Execute SQL Task Editor" has been the difficult part of this. Here are the settings.
General
Name = Compare Last File Create Date
Description = Compares the create date of the current file with a value in tbl_ImportFileCreateDate.
TimeOut = 0
CodePage = 1252
ResultSet = None
ConnectionType = OLE DB
Connection = MyServerDataBase
SQLSourceType = Direct input
IsQueryStoredProcedure = False
BypassPrepare = True
I tried several SQL statements, suspecting it's a syntax issue. All of these failed, but with different error messages. These are the 2 most recent attempts based on posts I was able to locate.
SQLStatement = exec ? = dbo.p_CheckImportFileCreateDate 'GL Account Import', ?, ? output
SQLStatement = exec p_CheckImportFileCreateDate 'GL Account Import', ?, ? output
Parameter Mapping
Variable Name = User::FileCreateDate, Direction = Input, DataType = DATE, Parameter Name = 0, Parameter Size = -1
Variable Name = User::IsNewFile, Direction = Output, DataType = BYTE, Parameter Name = 1, Parameter Size = -1
Result Set is empty.
Expressions is empty.
When I run this in debug mode with this SQL statement ...
exec ? = dbo.p_CheckImportFileCreateDate 'GL Account Import', ?, ? output
... the following error message appears.
SSIS package "MyPackage.dtsx" starting.
Information: 0x4004300A at Import data from flat file to tbl_GLImport, DTS.Pipeline: Validation phase is beginning.
Error: 0xC002F210 at Compare Last File Create Date, Execute SQL Task: Executing the query "exec ? = dbo.p_CheckImportFileCreateDate 'GL Account Import', ?, ? output" failed with the following error: "No value given for one or more required parameters.". Possible failure reasons: Problems with the query, "ResultSet" property not set correctly, parameters not set correctly, or connection not established correctly.

This occurs when the number of errors reaches the number specified in MaximumErrorCount. Change the MaximumErrorCount or fix the errors.
SSIS package "MyPackage.dtsx" finished: Failure.
When the above is run tbl_ImportFileCreateDate does not get updated, so it's failing at some point when calling the procedure.
When I run this in debug mode with this SQL statement ...
exec p_CheckImportFileCreateDate 'GL Account Import', ?, ? output
... the tbl_ImportFileCreateDate table gets updated. So I know that data piece is working, but then it fails with the following message.

This occurs when the number of errors reaches the number specified in MaximumErrorCount. Change the MaximumErrorCount or fix the errors.
SSIS package "MyPackage.dtsx" finished: Failure.
The IsNewFile global variable is scoped at the package level and has a Boolean data type, and the Output parameter in the stored procedure is defined as a Bit. So what gives?
The "Possible Failure Reasons" message is so generic that it's been useless to me. And I've been unable to find any examples online that explain how to do what I'm attempting. This would seem to be a very common task. My suspicion is that one or more of the settings in that Execute SQL Task node is bad. Or that there is some cryptic, undocumented reason that this is failing.
Thanks for your help.

Hi All,I tried to get a global variable in my task scritp by using "Dts.Variables("myVar").Value", every time I've got an errorThe element cannot be found in a collection. This error happens when you try to retrieve an element from a collection on a container during execution of the package and the element is not there. I've seen some examples online to get global varaibles in task script and all of them display the same code Any idea Franck

Is there a way to declare a global variable that can be used in seperate stored procedures?
I have a statistics table that tracks the inserts and updates for several stored procedures.
I need to have the procedure_A run and insert a count of inserted and updated rows.
Procedure_B needs to identify the row inserted by procedure_A and update the columns with a count of how many it inserted and updated.
Procedure_C needs to do the same as procedure_b.
I want to pass a global variable with the id of the row inserted by procedure_A to the rest of the procedures so that they will know which row to update. How do I do this? Can I?
Thanks.

Hi all,
I have a user using this tool, which creates a temporrary storeproc in tempdb.
when I don't give him permission on temp_db, it errors out and says you should create a system variable to point to a different database to create this sp.
Can anyone kindly explain to me how could this be done?
I appreciate any comment on this thread.
Thanks in advance.

Hi all,
Where can I find information/write up on importing data from Oracle, Lotus Notes, Lotus
Approach / MS Access / Lotus Spreadsheets and text files in to SQL Server 6.5? I've
scanned through books on-line but it doesn't contain any useful information about this.
Is it so that if I want to import data from any of the above mentioned databases then I first
will have to convert data into text(ascii) fromat from that database and then import from
text files??? Sounds weird, isn't it?
Cheers

Hey all,
I've recently been attempting a transform data task with a custom query for the source. Using the query, i've attempted to use global params, but it only ever seems to work if there is only one item in the global var. If I return an entire resultset, I get a "EXCEPTION_ACCESS_VIOLATION" instead. I'm trying to use it like "SELECT * FROM whatever WHERE ID IN(?)"
I've pondered this problem for quite some time now and I am wondering if there is a workaround for it. I know it would take much too long to do the same thing in activeX with a transform, so I would rather do it this way if I could.
Thanks in advance,

Hi!
I want to know the scope of a Global Variable in case of multi users.
Means i have declared a global variable in a function. And a new value is assigned to this global variable into this function, each time it is called.
So if, 3 users call this function at same time, then will the get different gloabl variables or same?

Shabber.

I need to block access to a process when it is running but the process appends outside of SQL in DB2 on a mainframe.
I planing to do something like :
declare @@LastProcessTime datetime
IF @@LastProcessTime is null or datediff(mi, @@LastProcessTime, getdate())>3
Set @@LastProcessTime=getdate()
IF datepart(mi, coalesce(@@LastProcessTime, getdate())< 3
BEGIN
update DB2 --takes 2 minutes
Set @@LastProcessTime=null
END
ELSE
Raise error 'Under processing since ' + usf_format_dt(@@LastProcessTime, 'HH:NN')
Is it the right approach?

Hello,I am having difficulty with global variables in DTS. SpecificallyI would like to instantiate a global variable with a value obtainedfrom a SQL database. I have created the global variable through thepackage properties section. Now i need to instantiate it with a valuefrom the database. Should i use an ActiveX Script Task to accomplishthis? If so can someone send me a link that shows the best way ofdoing this?Thanks,Billy

I just want to store the value of a parameter in a global variable that all my reports in the same project can use.
My goal is to create a dynamic query. For example:
Company Name: Widgets inc.
Divisions: Sales, Service, Tech, Accounting
I have a matrix and when I click on the more information button it goes to another report. I want the next report to know what division is currently selected in the dropdown parameter. So, being a VB programmer, I thought I could store parameter1.division.value into a global variable and update the variable whenever the parameter changes.
This way, on the next report, my query's where statement is the global variable.
@GlobalVariable = parameter1.division.value
Select name, address, phone FROM Employee WHERE division = @GlobalVariable
I am using Visual Studio to design this project although I would prefer to use VB or ASP. But this is my only stumbling block right now. Everything else is complete.
Please let me know if anyone can help.
Thanks.

I have a VBscript below which works fine, which creates a unique file name for a text source and creates it just fine. What I need is to use that file name in an insert statement in TSQL to load a record to a transaction table. How do I utilize this variable to do this?
Thanks
Function Main()
Dim oConn, sFilename
' Filename format - exyymmdd.log
sFilename = "ex" & Right(Year(Now()), 2)
If Month(Now()) < 10 Then sFilename = sFilename & "0" & _
Month(Now()) Else sFilename = sFilename & Month(Now())
If Day(Now()) < 10 Then sFilename = sFilename & _
"0" & Day(Now()) Else sFilename = sFilename & Day(Now())
sFilename = DTSGlobalVariables("LogFilePath").Value & _
sFilename & ".log"
Set oConn = DTSGlobalVariables.Parent.Connections("Text File (Destination)")
oConn.DataSource = sFilename
' oConn.DataTarget = sFilename
Set oConn = Nothing
Main = DTSTaskExecResult_Success

I am trying to pass a value from a VB Custom Task to
a DTS. The DTS doesn't get the value and I do not understand
why. Snipet follows:
oPKG.GlobalVariables.Item("gsAnyTypeData").Value = "Hello World"
oPKG.GlobalVariables.AddGlobalVariable ("gsAnyTypeData"), "Hello World"
oPKG.LoadFromSQLServer ".", , , 256, , , , DTSpackage_to_execute
oPKG.Execute
I've tried declaring the global variable in the called DTS and
I've tried without it. Neither contain the value when the DTS is
executed.
Thanks for your time and help,

hi everyone,
How do i declare a global variable in my package which takes a numeric value like User::VAR1 = 200402 and later on work on it
Later in the properties of the Dataflow i want to have this expression..
"select * from " + "TAB1" + " where Date=" + @[User::VAR1]
Here i want to subtract 190000 from @[User::VAR1] to get it in to myformat i.e the DATE format in the table
I can only see String datatype and othe datatypes wont allow me to to do any kind of manipulation in the expression:
and to be more specific what are
Int16
Int32
Int64
Double
I tried to use all of the above but the expression doesnt allow me as it says:
TITLE: Microsoft Visual Studio
------------------------------
Nonfatal errors occurred while saving the package:
Error at Extract: The data types "DT_WSTR" and "DT_I8" 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.
Any help would be appreciated..

We are running a DTS package with the dtsrun utility and would like topass a variable through it. Inside our package we have a VB scriptthat references a table that contains the information about all of ourjobs and we would like to pass a variable to tell it which jobs torun. The reason we cannot just add the variable to the VB script,i.e. in a where clause, is because we would like more then 1 bat fileto run this package. We want some jobs to run with 1 bat file andother jobs to run with another. If we could pass through a variableof 1 that would refer to a column within our table then only thosejobs would run at that time. Make sense?Any help is appreciatedThanks

I am new to DTS, but really enjoy it and was wondering if someone could help me with the following small vb app.
I am using the following DTS insert statement to insert records into my table. I have multiple textboxes that needs to be filled and then inserted, none of them exept Nulls. How can I modify my code to insert those textboxes as well as run through the boxes and then check if they have nulls and NOT insert the ones that has nulls?
My form has 9 textboxes. Textbox1, 2, 3 Needs to insert values into the first column. Textbox4, 5, 6 into the second and then Texrbox7, 8, 9 into the last column.
My question is how do I format the following line of code to do what I need?
oCustomTask1.SQLStatement = oCustomTask1.SQLStatement & "Values ('1rowst', '2rowst', '3rowst')"
I think it is something like this, but I am Really not sure and some help would be greatly appretiated:
oCustomTask1.SQLStatement = oCustomTask1.SQLStatement & "Values ('Textbox1', 'Textbox4', 'Textbox7')"
I am really not sure.
Here is all the code:
Public Sub Task_Sub1(ByVal goPackage As Object)
Dim oTask As DTS.Task
'Dim oLookup As DTS.Lookup
Dim oCustomTask1 As DTS.ExecuteSQLTask2
oTask = CType(goPackage, DTS.Package).Tasks.New("DTSExecuteSQLTask")
oTask.Name = "DTSTask_DTSExecuteSQLTask_1"
oCustomTask1 = oTask.CustomTask
oCustomTask1.Name = "DTSTask_DTSExecuteSQLTask_1"
oCustomTask1.Description = "Execute SQL Task: undefined"
oCustomTask1.SQLStatement = "Insert into TestTable (Test1, Test2, Test3) " & vbCrLf
oCustomTask1.SQLStatement = oCustomTask1.SQLStatement & "Values ('1rowst', '2rowst', '3rowst')"
oCustomTask1.ConnectionID = 1
oCustomTask1.CommandTimeout = 0
oCustomTask1.OutputAsRecordset = False
goPackage.Tasks.Add(oTask)
oCustomTask1 = Nothing
oTask = Nothing
End Sub

I'm trying to do something very simple, and having a tough time with it.
I've got a Global Variable that gets a string value assigned to it in a Script Task, and then I need to access that value in Execute Process Task Expression. When running, by the time it gets to the Process Task, the global variable's value in the expression is still blank, even though a breakpoint on the task shows that it does have a value.
What am I doing wrong? This seems too simple to give me this much problem.

Hi,
This problem is connected with the query i posted yesterday regarding insertion of global variables. I was able to insert the variable in a table to check its value.
This value is mapped to the global variable in a previous Execute SQL Task. But when I use the same global variable to insert in a table, default value 0 is inserted.
My query is does the global variable declared at the package level does not store the value mapped across multiple tasks in control flow?
How can i insert the value stored in a variable in a table from previous SQL Task.
Can anyone suggest some solution,links to try a workaround?
Thanks in advance.

Aman

I'm new to SSIS so please be gentle...
I'm creating a package that needs to go to an FTP site (FTP Task), download a file, unzip it and then process a series of table loads for the 12 text files that will be unzipped. My problem is that the zip file is a date (yyyymmdd.zip) which is normally the previous day of execution EXCEPT on Mondays when it would be the previous Friday's date. My thought is that IF (magic question) I could determine the day of the week in the SSIS package, I know that Tuesday-Friday is just a formatting exercise of getdate()-1 and Monday would be getdate()-3 but I can't seem to find a way (function?) that will allow me to determine the day of the week?
Thanks in advance!
