Integration Services :: How To Use Temp Table / Variable
Aug 8, 2014
It's SQL 2008 R2. I need to bring data from Oracle using .Net Providers/ODBC Data Provider to MS SQL table converting Oracle UTC dates to PST. The source connection type cannot be changed as it's given. For the Destination I'm using the OLE DB.
As the truncate all and load could take time I'm trying to use a temp table or a variable to use it further with t-sql merge or not exists to bring/add the only new records to the destination table.
I'm trying different scenarios that is all failed.
Scenario A:
1. In DTF after OLE DB Source I'm using the Derived Colum to convert dates. It's working well.
2. Then use Recordset Destination with an object variable User::obj_TableACD. It's also working well.
3. Then I created a string variable with a simple query that I could modify later "select * from " + (DT_WSTR,10)@[User::obj_TableACD] trying to get data from the recordset object variable but it's not working.
Scenario B:
1. Created a store procedure to create a temp table.
2. Created a string variable to execute SP str_CreateTempTable: "EXEC dbo.TempTable". It's working well with the SQL Task with SQLSourceType as Variable.
3. Then how to populate the temp table from the Oracle source to bring data into the Destination?

I have to combine data from DB2 and SQL server and do some manipuation. I wanted to do union all and put in temp table for further manipulation. I created a temp table in control flow,
CREATE TABLE ##SiteTemp
(
LEVEL2 VARCHAR(20),
LEVEL3 VARCHAR(25)
Then I was trying to use that temp table for destination but I can do see that in destination. I have to automate the package and do that everyday. I read some blogs but did not understand how they did it. I did set retainsameconnection to true. I did find this thread but i did not understand how it was done. URL....
I have two OBL DB sources, Then I have Union ALL and then OLE Destination in data flow.I have the temp table code in Execute sql task.

My Requirement IS : 1<sup>st</sup>run: if the record does not exist in the table insert the record (file_name, last_modified_file_date) and create a copy in the archive folder with file_name_currentdate.csv
Daily run: retrieve the last_modified_file_date from the input file and check if the retrieved date is greater than the last_modified_file_date in the table:
If true: create a copy of the input file in the archive folder and update the last_modified_file_date in the table with the retrieved date
If false don’t do nothing because the file has been archived in one of the previous runs.I have already retrieving the modified date and File Nae iserting into Filename Table: (That table has 2 columns which are FileName and FileDate) so In script task everytime the variable getting Modified date(retrieve the last_modified_file_date from the input file). How I can Compre the existing table record and variable. I have already imported the all Filenames and Modified into table like below.

I have an SSIS package that creates a csv file based on a execute sql task.
The sql is incredibly simple select singlecolumn from table.
In the properties of the execute sql task I specify the result set as "full result set" when I run it I get the error that: Error:
The type of the value being assigned to variable "User::CSVoutput" differs from the current variable type.
Variables may not change type during execution. Variable types are strict, except for variables of type Object.
If I change the resultset to single row then I only get the first row from the DB (same if I choose none), If I choose XML then I get the error that the result is not xml. What resultset type do I need to choose in order to get all the rows into the CSV? The variable I am populating is of type string and is User::CSVoutput

Hi guys
What's this nonsense all about?
Im attempting to install the Analysis Services on NT 4 and I get this strange error message (about not finding the TEMP environmental variable).
I checked the TEMP environmental variables they are just fine thank you very much.
Did anyone encounter this thing?
Thanks.

I need to grab data from teradata(using odbc connection).. i have no issues if its just bunch of joins and wheres conditions.. but now i have a challenge. simple scenario, i have to create volatile table, dump data into this and then grab data from this volatile table. (Don't want to modify the query in such a way i don't have to use this volatile table.. its a pretty big query and i have no choice but create bunch of volatile tables, above scenarios is just mentioned on simple 1 volatile table ).
So i created a proc and trying to pass this string into teradata, not sure if it works.. what options i have.. (I dont have a leisure to create proc in terdata and get it executed when ever i want and then grab data from the table. )

I don't know if it's a local issue but I can't use temp table or table variable in a PP query (so not in a stored procedure).
Environment: W7 enterprise desktop 32 + Office 2012 32 + PowerPivot 2012 32
Simple example:
declare @tTable(col1 int)
insert into @tTable(col1) values (1)
select * from @tTable
Works perfectly in SQL Server Management Studio and the database connection is OK to as I may generate PP table using complex (or simple) queries without difficulty.
But when trying to get this same result in a PP table I get an error, idem when replacing table variable by a temporary table.
Message: OLE DB or ODBC error. .... The current operation was cancelled because another operation the the transaction failed.

Hi all, Im trying to use a temporary table along with a gridview. But i keep getting an issue that says that I need to declare the variable name.
Right now, I have it set up that I have a permanent table in the database that is serving as my temporary table, however Im running into issues if multiple users access at once... So I would like to dynamically create a table and use that for my temporary table and then drop the table when the user is done with it...
heres my code so far..Private Sub AddRecords(ByVal prodins As String, ByVal releaseins As String, ByVal opsysins As String, ByVal currelins As String, ByVal schemains As String, ByVal commentins As String, ByVal freeformins As String)
Dim tablevar As String = lblRequestor.TextDim tablename As String = "##" + tablevar Dim myConnection As New SqlClient.SqlConnection
Dim query As String = "CREATE TABLE " + tablename + "(UniqueID int Identity(1,1), Product varchar(50), OperatingSystem varchar(50), CurrentRelease varchar(50), Release varchar(50), SchemaSize varchar(50), Comments varchar(50), TempRelease varchar(50), FreeFormFlag varchar(50), sourcereleasedir varchar(125))"
Dim query2 As String = "INSERT INTO " + tablename + "(Product, Release, OperatingSystem, CurrentRelease, SchemaSize, Comments, TempRelease, FreeFormFlag) VALUES ('" & prodins & "','" & releaseins & "', '" & opsysins & "', '" & currelins & "', '" & schemains & "', '" & commentins & "', '" & currelins & "', '" & freeformins & "')"Dim myCommand As SqlClient.SqlCommandmyConnection = New SqlClient.SqlConnection("Data Source=mydatasource")
myConnection.Open()myCommand = New SqlClient.SqlCommand(query, myConnection)
myCommand.ExecuteNonQuery()myCommand = New SqlClient.SqlCommand(query2, myConnection)
myCommand.ExecuteNonQuery()
myConnection.Close()
And here is my query for the gridview....
SelectCommand="SELECT * FROM @tablename where FreeFormFlag <> 'Y'"
and
<SelectParameters>
<asp:ControlParameter ControlID="tablename" Name="tablename" PropertyName="Text" DefaultValue="##default" />
</SelectParameters>
so @tablename is set to the value of a textbox i have hidden which the textbox gets the username of the user and adds ## to it..so if john doe comes on... the texbox reads ##jdoe... and thats what im trying to name the temp table. SO the syntax is all there.... But i keep getting an error saying i need to declare @tablename... which is puzzling to me.. I tried doing
declare @tablename varchar (50)
select.....etc.
but then it brings up an error saying... @tablename is already declared, each variable must be unique..., You must declare @tablename... It tells me that its already declared then tells me i must declare it??? it makes no sense..
Anyone have any ideas?
Thanks,

Can someone send me an example of creating a variable to use instead of a temp table? I cannot find an example on books on line, but know it is possible in SQL2000.
Thanks,

Hi All,Hope someone can help me...Im trying to highlight the advantages of using table variables asapposed to temp tables within single scope.My manager seems to believe that table variables are not advantageousbecause they reside in memory.He also seems to believe that temp tables do not use memory...Does anyone know how SQL server could read data from a temp tablewithout passing the data contained therein through memory???Is this a valid advantage/disadvantage of table variables VS temptables?

In a previous post "Could #TempTable within SP cause lock on tempdb?" http://forums.microsoft.com/msdn/showpost.aspx?postid=2691763&siteid=1
It was obvious that we have to limit the use of #Temp table to a minimum. Let assume that some of the temp tables are really difficult to replace and we have to live with them.
Would it be easier on tempdb if the #TempTable is replaced by a table variable? Or do they all end up in tempdb?
Thanks in advance for any help.

I have tried with this thing for hours and I can't get it to parse.
Trying to get last year so the expression should evaluate today as of "12/31/2014"
I looked all over on Google and couldn't find an expression to copy so I've been playing with it.
Here is what it is in SQL Server:
SELECT DATEADD(dd,-1,DATEADD(yy, DATEDIFF(yy,0,GETDATE()),0))
Absolutely could not get it to parse..even with DT tags, etc...

I have created a SSIS package that runs several reports exporting the file output to a shared directory. Then I email these files as attachments to an email group. I got everything working so far. But when I checked the email there are only some of the attachments (3 out of 6 files).I have created a variable that uses an expression to concatenate several filenames and their paths separated with a "|". When I evaluate the expression it list all six files. When I use the variable in an expression when assigning the "FileAttachments" property in the Expressions tab in the Send Mail Task editor and I evaluate the expression, it only shows 3 out of the 6 files.
Each file name and path is less than 100 characters. Why is this task only grabbing 3 out of the 6 files. If I check the shared directory all 6 files are there. Also, there are two paths in the package that input into the Send Mail Task each creating a different set of report files. Only one of the paths files are getting attached. The connectors to the Send Mail Task are set as Evaluation operation: "Constraint" and the Value: "Completion". Under Multiple constraints I have selected "Logical AND, All constraints must evaluate to True".

I am having trouble finding the correct syntax to access a variable. I have a variable defined in the Variables window: The variable name is formatedDate. The DataType is String.
I am successfully setting the value of the variable in a Execute SQL Task. The SQL is as follows:
SELECT LEFT(CONVERT(VARCHAR, MAX(ReportDate), 120), 10) as formatedDate
from DimReportDates
The Result Set is set to “Single Row” and properly set up.
No problem so far. I can see with a watch that the variable has the correct value, something like:
‘2015-09-30’
Now, in a subsequent step, a Data Flow Task, I want to access the variable. Actualy it is in the SQL statement of a OLE DB source in the Data Flow… I have the following:
Declare @sDate smalldatetime
SELECT @sDate = xxxxx
I have tried several things substituting xxxxx above, but nothing seems to work. One variation was
@[User::formatedDate])
Another was
((DT_WSTR, 10) @[User::formatedDate]).
I think I’m close, but just can’t get it. What is the correct syntax.

I have a set of .dtsx files that connect to an Oracle database. The Oracle username and pw values are saved in variables set up in the .dtsx files. These two variables do not have expressions, rather, these two variables feed other variables and their expressions.Theses files are now moving from one environment to another and the Oracle username and pw must be updated to connect to the new Oracle environment.
Upon updating the variables, the packages expressions update as expected, however, when saving the file to disk, the updated variables aren't saved and the values revert back to the original values.
How are variables updated in .dtsx packages that will allow changes to be saved?

I have to import a number of excel spreadsheets. I'm using the classic Foreach Loop inside another Foreach loop approach. The outside loop (Foreach File Enumerator) cycles through the Excel files, while the inside loop (Foreach ADO.NET Schema Rowset Enumerator - ExcelSchema - Tables) to cycle through the individual Excel sheets in each file.
Nothing special there; however, for some reason these excel files have some "phantom" tabs that should not be imported. I call them phanton because they show up as an importable tab in a SSSIS import wizard but actually are not listed in the excel file structure (no, they are not hidden tabs, I checked).
My idea is to use a constraint to NOT import those phanton tabs. The name convention should allow me to do that because the normal tabs have the name 'AAAAAAyyyymmdd$' and the phantom tabs show up as 'AAAAAAyyyymmdd$'_xlnm#_FilterDatabase (the line below was captured from the Local Variable window and show one of the phantom tabs name).
+ User::WorksheetName {'AAAAAAyyyymmdd$'_xlnm#_FilterDatabase} String
I tried using Len (@[User::WorksheetName]) == 17, which corresponds to the length of the normal tabs name ('AAAAAAyyyymmdd$'). However, it does not work. For some reason the portion of the phantom tab name after the ending single quote (_xlnm#_FilterDatabase) appears to be ignored.
I tested with a number of different expressions, including reversing the variable, to no avail. It seems that internally just the standard name between quotes is what the constraint sees.

I've created a SSIS Package and it's connection is based on Environment Variable(please seeprocedure).
Now, I'm trying to create a job that calls this package and it seems that when you view Data Sources, it still pointing to the old server.
But when you open-up the package through BIDS in the same server, it's using the new reference that I have specified in the environment variable (please refer to the first image).
I came across this blog with the same issues as mine. He suggested to re-start the SSIS Service which I already did but nothing happens. I even re-started the SQL Agent but still no luck.
I'm not sure what else is missing except for re-starting the machine which is the last thing I want to do as this is PRODUCTION server.

My Execute SQL Task will store the file name into a variable(mFile) of type string datatype.
Now I wanted a script task (C# code) to create a filename from the variable (mFile) value.
Since it is a common issue I tried a lot in the internet but none of the queries worked.
