Passing Variable Values Into A Nested SQL In An OLEDB Datasource
Aug 21, 2007
All:
I am trying to code the following SQL into an OLEDB data source but it is not allowing me to do so because I think the variables are nested in multiple SQL statements. I have seen other posts that suggest using a variable to store the SQL but I am not sure how it will work.
I would also like to mention that the OLEDB source executes from within a For Each loop that is actually passing the values for the variables, which was one of the reasons I got stumped on how I could have a variable store the SQL.
Here is the SQL:
select b.ProgramID, b.ProductCode, b.BuyerID, b.Vendor,sum(a.Ordered) As Qty_Pruchased
From SXE..POLine a INNER JOIN
(SELECT VIR_Program.ProgramID, VIR_ActiveSKU.ProductCode, VIR_ActiveSKU.BuyerID, Vendor
FROM VIR_Program INNER JOIN
VIR_ActiveSKU ON VIR_Program.ProgramID = VIR_ActiveSKU.ProgramID
INNER JOIN Vendor ON VIR_Program.VendorID = Vendor.VendorID
WHERE ProgramFreq=?) b
ON a.ProductCode = b.ProductCode
WHERE a.TransDate >=? AND
a.TransDate ?
Group By b.ProgramID, b.ProductCode, b.BuyerID, b.Vendor
Is it possible to assign multiple columns from a SQL query to one variable. In the below query I have different variable (email, fname, month_last_taken) from same query being assigned to different columns, can i pass all columns to one variable only and then extract that column out of that variable later? This way I just need to write the query once in the complete block.
DECLARE @email varchar(500) ,@intFlag INT ,@INTFLAGMAX int ,@TABLE_NAME VARCHAR(100)
I have a proprietary OLEDB data source that works alongside a SQL database. Both are pretty big. I am trying to find a fast way of copying the data from the OLE source into a table in the SQL database. I am working in ASP.NET, and the easiest way is to have 2 connections, open the OLEDB and fill a datatable, then go through the table line by line and do a parametized insert. That works but takes far too long.
I am looking for something along the lines of "SELECT INTO tblB FROM tblA", or even "INSERT INTO tblB SELECT * FROM tblA", anything that is faster than the above. Can you do this in SQL but accessing an OLEDB datasource?
I have written a package which accepts variables for the server, initial catalog & table name.
I execute sql to drop the following stored procedure, then following sql statement to create it.
================================================================ SET ANSI_NULLS ON GO SET QUOTED_IDENTIFIER ON GO
CREATE procedure [dbo].[SP_CreateMatchProc] @sTable varchar(300) as BEGIN SET NOCOUNT ON declare @cmd nvarchar(2000) set @cmd = '''' Set @cmd = 'SELECT REPLACE(field1 + field2 + field3 + field4 + field5, '' '', '''') AS dBString ' + 'FROM ' + @sTable + ' ORDER BY <table>_ID COLLATE Latin1_General_CI_AS' exec (@cmd) END GO
Then in the Oledb source (validateexternalmetadata = false) I use "sqlcommand from variable" with a variable value of "SP_CreateMatchProc '<tableName>'"
The package runs fine in the IDE regardless of variable values, but when I created a batch file which calls dtexec I get a failure:
Error: 2007-10-04 08:46:42.82 Code: 0xC0202005 Source: Data Flow Task OLE DB Source [310] Description: Column "dBString" cannot be found at the datasource. End Error Log: Name: OnError Start Time: 2007-10-04 08:46:42 End Time: 2007-10-04 08:46:42 End Log Log: Name: OnError Start Time: 2007-10-04 08:46:42 End Time: 2007-10-04 08:46:42 End Log Error: 2007-10-04 08:46:42.82 Code: 0xC004701A Source: Data Flow Task DTS.Pipeline Description: component "OLE DB Source" (310) failed the pre-execute phase and returned error code 0xC0202005. End Error
with the ValidateExternalMetadata set to TRUE I get
Error: 2007-10-04 09:21:35.20 Code: 0xC004706B Source: Data Flow Task DTS.Pipeline Description: "component "OLE DB Source" (10621)" failed validation and returned validation status "VS_NEEDSNEWMETADATA". End Error
the most notable thing I see there is that it looks like a different ID (310) with out the validation and (10621) with it.
I've got an intranet page that connects to my SQL server, and I'm trying to force it to use NT Authentication when it does.
Already the Intranet uses NT Challenge-and-response authentication so that when I go to an intranet page I have to login. But then when I go to the page that connects to SQL, I get:
Microsoft OLE DB Provider for SQL Server error '80040e4d'
Login failed for user 'IUSR_COMPUTERNAME'.
Why isn't it passing MY user id? Why is it trying to use the anonymous IUSR id?
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 have created lastUpdatedDate variable on package level. I have run a sql task and store a date in that variable.
now i am trying to pass that variable as parameter to oledb source connection (using command). it seems that we cant pass parameter in any sub query or derived table in query. its only working in outer query as soon as we place ? in WHERE clause of inner query it start throwing an 'Syntax Error' error saying that connection provider might not support that.
any idea ?????
I dont want to use command variables as my query is going to be quite big.
Note : I have tried Sql Server Native and OLEDB provider for sql server and this behaviour is seems to be constant in both.
Though I am a novice to MS SQL server (2000 I believe), I can do almost!everything I need. Maybe not efficiently, but usefully. However, I havea problem -- a complex query problem...I can create a parameter query in a stored procedure, but how do I usethe result set of a parameter query in a select query (in the same oranother sp)? In short, if a select query contains a result table that isgenerated as a parameter query, how do I pass the parameter through theselect query to the nested parameter query?For example, if I have a sp parameter query called [e_typerows], I couldwrite the following select query which uses the (single) result set from[e_typerows] plus other tables or views:SELECT TOP 100 PERCENT bi_occ_01_e.row, bi_occ_01_e.pos,bi_dictionary_e.typestring, bi_occ_01_e.shadowFROM bi_dictionary_e INNER JOIN(bi_occ_01_e INNER JOIN[e_typerows] ON bi_occ_01_e.row = [e_typerows].row) ONbi_dictionary_e.typeid = bi_occ_01_e.typeidORDER BY bi_occ_01_e.row, bi_occ_01_e.posEven though [e_typerows] is a (storted procedure) parameter query thiswill work IF my parameter in [e_typerows] has a default, say "yyyy". Inthe default case no parameter needs passing. But what if it doesn't havea default value or if I need to pass a parameter to it?Is there any way to replace[e_typerows]in the above query with somethinglike [e_typerows @myparameter='xxxx']? (Maybe I should try that! I'veseen nothing about it though.)My parameter query, [e_typerows], looks like this in fact:@typestringparameter varchar(100) = "yyyy"SELECT dbo.bi_dictionary_e.typestring, dbo.bi_occ_01_e.rowFROM dbo.bi_occ_01_e INNER JOINdbo.bi_dictionary_e ONdbo.bi_occ_01_e.typeid = dbo.bi_dictionary_e.typeidGROUP BY dbo.bi_dictionary_e.typestring,dbo.bi_occ_01_e.rowHAVING (dbo.bi_dictionary_e.typestring = @typestringparameter)Any suggestions would be greatly appreciated! (For the moment, I firstgenerate the parameter query result set, then I loop through each row ofthat result set and do a select query with that row as a parameter --very complicated!, though it does work.)
(I asked this question in another forum, but think it may be more of asql question)Hi.I bet this is a 101 question, but i'd appreciate any help!I am in the 'where...' section of the configure data source wizzard .(Visual Studio 2005) Column:(From my table) I select 'UserName' from drop-downOperator: I select '=' from drop-downBUT how do I get the UserName (The user is signed into the app) to pass to the where clause?Is it from the Form? Profile? Session?Ive tried Form.Page.User.Identity.Name.ToString; Form.NamingContainer.Page.User.Identity.Name.ToString; Profile.UserName; NOTHING works. IF I set the default value to a user name (eg joe_user) it retrieves fine, but I need it to retrieve for the currently signed in user. THANKS In advance.... Dan
I have a single variable to be utilitized in my SQL Where clause... Select *FROM projectsWhere project_id = @id How do I use this c# variable in the datasource? string TableID; TableID = "192.AB"; I know this is simple, but I figured I'd ask. I don't want to do a work around , like a hidden textbox with the value assigned, and then link the datasource to the tb control, seems extremely hackish.
I would like to create a stored procedure that imports an Excel file toa sql server table. I need to be able to pass the path to thespreadsheet to the stored procedure like so:CREATE PROCEDURE dbo.ImportSpreadsheet(@Path nvarchar(120))ASSELECT * INTO AuditFROM OPENDATASOURCE( 'Microsoft.Jet.OLEDB.4.0','Data Source = ' + @Path + ';Extended Properties=Excel 8.0')...Audit$I will call the stored procedure from within my .NET application andpass it the path as @Path. The path will be chosen by the user at runtime and will be something similar toC:SpreadsheetsAudits.xls.I can make this run in the Query Analyzer:SELECT * INTO AuditFROM OPENDATASOURCE( 'Microsoft.Jet.OLEDB.4.0','Data Source = ''C:SpreadsheetsAudits.xlsAudit_TC.xls'';Extend edProperties=Excel 8.0')...Audit$I could run the SQL directly from my app, but I like to use storedprocs whenever I can for the speed and flexibility. I can change thestored proc and not have to recompile/reinstall the app.Any help would be greatly appreciated.
I have a parent package that contains two children... The second child depends on the succes of the first child.
THe first child generates a variable value and stores it in an Environment variable ( Visibility - All ) ...After the first succeeds, the second will start executing and will pick up the variable value from environment variable( through package configuration setting )...
Unfortunately, this doesn't work...As the second child picks the stale value of the environment variables...Essentially it assigns variable value not after the first child is finished, but right at the beginning of parent execution...
I tried to execute coth children as Out Of Proc as well as In Proc...The same
Would anybody have an idea how to resolve this problem?
Hey all, I was wondering what the best method of checking on page_load if a datasource control is pulling back nothing from a database. I want to display a message explaining that there is no data to be displayed. How would I go about doing that? I have tried searching google and whatnot but didn't find anything really helpful. Here is the current code for the data source control. <asp:SqlDataSource ID="SqlDataSource1" runat="server" ConnectionString="Data Source=.SQLEXPRESS;AttachDbFilename=|DataDirectory|EventInsider.mdf;Integrated Security=True;User Instance=True" ProviderName="System.Data.SqlClient" SelectCommand="SELECT Events_Groups.GroupName, Events_Groups.GroupID FROM Events_GroupMembership INNER JOIN Events_Groups ON Events_GroupMembership.GroupID = Events_Groups.GroupID WHERE (Events_GroupMembership.UserID = @UserID)"> <SelectParameters> <asp:SessionParameter Name="UserID" SessionField="UserID" /> </SelectParameters> </asp:SqlDataSource> But I have no idea what the code behind would be to check it on page_load. If there is no way to particularly do this, do you have to do it per control? Like dropdownbox's or gridviews? I am just confused on how to check to make sure there is data to be displayed. Thanks, Chris
I need to use a nested cursor in SQL server 2005. I have never done this before. The problem here is that I need to use "@@FETCH_STATUS' twice.Once for my inner loop and once for my outer loop. If there is a way to use two different @@FETCH_STATUS variables at once, I would like to know how. Here is my code. The inner loop is currently pseudo code and I just need to figure out how to code it. DECLARE @mycur1 CURSORDECLARE @mycur2 CURSORDECLARE @InMarketId INTSET @InMarketId=575 -- Hard code for now. Just for testing.DECLARE @test VARCHAR(10)SET @mycur1 = CURSORSET FORSELECT SubDivisionId FROM SubDivision WHERE MarketId=@InMarketIdOPEN @mycur1FETCH NEXT FROM @mycur1 INTO @testWHILE @@FETCH_STATUS = 0 BEGIN PRINT @test-- Begin Inner Nested Loop-- FOR EACH SubDivisionId in SubDivisionSubMarket SDSM delete from SubMarket SM Where SDSM.SubMarketId=SM.SubMarketId -- End of Inner nested Loop FETCH NEXT FROM @mycur1 INTO @test ENDDEALLOCATE @mycur1------------------------------------------Here are my three tables I am scripting agains and a description of each.

First let me say that I'm new to SSIS, so be gentle with me.
I need to extract a limited set of data from a very large view in Oracle (I know, yuk!). The view contains millions of rows, but I only need the child matches of 343 unique keys in a one to many relationship. In pure SQL the query would look something like this.
Select proj, tn, rn, total FROM Oracle.view WHERE proj in (select distinct proj from MSSQL.dbo.projlist)
As you can see, this is an impossible query on many levels.
My first thought was to get the runtime list into a variable and use that variable as a parameter in the Oracle OleDb Source. Alas, the Oracle source will not allow me to add a parameter.
My second thought was to use a script component and build a SQL_Command string into a variable with all of my keys included. Then use the read_write variable as the SQL Command from variable in the Oracle Source. My attempts to construct such a variable expression have failed.
Hi, I want to be able to spot when the same employee name gets added to my grid. This is to ensure that I cannot not have the same firstname and lastname (i.e. cannot have 2 John Smiths). It is kind of like spoting for duplicates but they are not PKs. I was hoping if there was a way you could identify the the feild values on the "inserting" event of the datasource so I could put some logic in. The reason for placing it there is because we have the e.cancel = true command. Thanks in advance, Jon
The results we got are a model with intercept only. if we don't use the nested variable (the red line) we get a rigth model . (we had more variable ....)
Is there any way to convert a bind variable, which is a list of integer or string values, to nested table in MS SQL Server. I am looking for something like
CAST in Oracle, which converts a varray type column into a nested table. Do we have something like this in SQL Server.
in Oracle:
SELECT CAST(s.addresses AS address_book_t) FROM states s WHERE s.state_id = 111;
I have read about Table valued Parameter, but I am looking for another solution.

I have a parameter which should take multiple values into it and pass that to the code that i use. For, this i created a parameter and temporarily for testing i am passing some values into it.Using a dynamic SQL i am converting multiple values into multiple records as rows into another variable (called @QUERY). My question is, how to insert the values from variable into a table (table variable or temp table or CTE).OR Is there any way to parse the multiple values into a table. like if we pass multiple values into a parameter. those should go into a table as rows.
Hi, This is pretty simple but I am doing somethin really stupid somewhere, I am trying to pass a value to a variable declared in a package using some SQL code, I declared a variable "var1" and assigned the scope to the package , then I dropped a execute SQL task within the package and wrote a simple sql code that would get the maximum id from a table, "select max(id) from table" , now I want to assign the variable this max value.so in the parameter mapping tab I select the variable give it a parameter name of 0 and size of -1 along with direction of "output". everythin looks simple but when I try to use this variable value in my next execute sql task it behaves weirdly, I am trying to update anothet table using this variable value, so I add another task and put this code in there " update table2 set id = ? " , and on the parameter mapping tab I set the direction as input, however when I look at the column it updated th column with a weird number , xomethin like "230072408" which doesnt mean anything. I know that tha max value of ID is 10. Please help.
I am using a foreach loop, with the data from an ado recordset, which contains the table name that I wish to write data to an OLEDB data dest. The table names are retrieved from an execute sql task in the an object var. Within the foreach loop, for each table name, I then use a datareader to an ado.net source to pull data from that table, via an expression construct into a variable - i.e. "select * from " + @[User::table_name]. This works fine for the first table, in which mappings are setup using the SSIS design environment. The data is retrieved. I then use a variable and set the data access mode for the oledb destination to "Table name or view name variable". This also saves data fine for the first table in the loop in the oledb dest. When the next table name is retrieved from the ado provider in the foreach loop, the datareader fails, as it still thinks the metadata mappings are from the first table, which was used for the mapping in the design environment. I.E. FIN_CLASS is a column from the first table in the loop.
Error: 0xC0202005 at Data Flow Task, DataReader Source [7181]: Column "FIN_CLASS" cannot be found at the datasource.
I have set the following properties, that I thought (in my feeble mind), are supposed to avoid that behavior. For the datareader, I set ValidateExternalMetadata to false, and for the data flow task (container for the datareader), I set DelayValidation to true. These settings, according to the doc, are supposed to evaluate metadata for the datareader source at runtime (not design time), so that the column metadata is dynamic, and so that the subsequent oledb destination can use the "data access mode" for the oledb destination of "Table name or view name variable".
If I cannot get this to work, I have 2 options: Use OPENQUERY via dynamic t-sql statements, OR create 30 separate flows in SSIS - one for each table - not looking forward to that one.
( select min(cast(f.valuestr as float)) from bvfindings f where f.ObjectName = 'Hematocrit' and f.sessionid = s.sessionid and f.ValueTime > s.open_time)

i modified the query

Hi All, Would somebody be able to help me from pulling my hair out!??I have a form with a radiobuttonlist. I would like to change my select statement depending on what radiobutton value is selected.E.g.SELECT * FROM table WHERE <<variable from radiobuttonlist>> LIKE 'Y'So,if radiobutton value selected = 1, it will select * from column A in the dbif radiobutton value select = 2, it will select from column B in the dband so on... Am i attempting to do the impossible?Thanks All,

I am trying to get data from a database through a select statment and I want to pass the return query to a c# string variable. Any idea how can I do this?
could anyone please help me to resolve this issue? here's my sql query which retrieve last 3 month data t.execute(SELECT * tbl1 where nmonth >= datepart(mm,DATEADD(month, -3, getdate())) or nmonth <=datepart(mm,getdate()) and empno='"+emppip+"'") now instead of passing 3 in this query(datepart(mm,DATEADD(month, -3, getdate())) ) i need to pass a variable to retrieve data based on user requirements. i tried this way, dim mno as n mno=4 t.execute(SELECT * tbl1 where nmonth >= datepart(mm,DATEADD(month, -'"+mno+"', getdate())) or nmonth <=datepart(mm,getdate()) and empno='"+emppip+"'") its not working. can i achieve this using stored procedure? or can i directly pass a variable to sql synatax? thanks for any help

hi guys what is the syntax for using the passing variable part into the name of a table in a store procedure. in particular: (assume already declared the variable periodseq.
select * into Temp_Usage_@periodseq from Master_usage where Master_usage.PERIODSEQ = @periodseq
in particular the Temp_Usage_@periodseq line of code, how do i "add" the periodseq (which is a number) to the end of the name of Temp_Usage, i.e: Temp_Usage_112 is the syntax an & like Temp_Usage_&@periodseq? Cheers Champinco
