Passing A SSIS Global Variable To A Declared Variable In A Query In SQL Task

Mar 6, 2008

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.

Passing Variable Value Through Environment Variable

Feb 15, 2008



Hi All!

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?

Thanks in advance for any help!

Passing Value To A Variable

Aug 9, 2007



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.

Thanks

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.

Passing A Variable To A SQL Statement

Mar 10, 2008

I've been coding a few years and SSIS makes me feel more stupid than any program I've ever used.
I've read BOL and bought a book. Can't say either one has really helped.

I'm still a complete idiot after one week of working with it. I apologize for asking so many stupid questions.

What I'm trying to do now is parameterize a SQL statement.

I have a variable that's a string. I have a DataFlowComponent as a data source. I find references all over the Internet and this forum to something called an "ExecuteSQLTask" but I sure can't figure out what that is. In my toolbox I have data flow sources for DataReader, Excel, Flat Files, Old DB, Raw file, and XML but no Execute Sql Task.

Anyway SELECT * FROM TABLE WHERE COLUMN='Value' in the SQL Command property is simple enough. Now I want 'Value' to be a variable. You know, like in T/SQL DECLARE @Foo VarChar(25). Creating the variable is easy as pie.

I have found at least 10 different examples of specifying variables on the web, all of which claim to be SSIS examples, Is it User::Variable? @[User::Variable]? @Variable?

I want to read rows from a table, with a a variable value in the WHERE clause, and pass them to the fuzzy lookup task.

Is my approach fundamentally flawed in some way?

Passing Variable On To Next Record

Jan 28, 2008

I am running a query in with my daily import job that lets me know if a duplicate record was imported into the system. If so I want to setup my email table to mail me the following information. My code works fine except the value of the variable @ID is only giving me the first record in the set. How do I pass it on to the next record? I get the right number of rows inserted into the email table but the @ID variable is the same for all 3.

Drop Table #SER1

Select id#,

Colx=Count(*)

Into #SER1

From Business

Group By id#

Having Count(id#) > 1


Declare @ID Varchar (4)


Select @ID = ID# from #SER1


INSERT INTO Email

( [To],

[Subject],

[message],

[Table],

TableUKey,

TableSource

)

SELECT

'Firstname.Lastname@Company.com',

'Duplicate ID# Imported',

'ID# ' + @ID + ' has been imported multiple times ' + ' on ' + cast( getdate() AS varchar(30)) + '. You need to remove the record and rerun the import.',

'Daily Import',

@ID, 'Daily Import'

Passing Parameter Value To Variable

Jun 1, 2007

Hello,

I can't figure out how to pass values from report parameters to a variable in custom code.
I have a Report Parameter called Parm1 of type string. It contains the following:

Label: Value:
Labell1 Value1
Label2 Value2

In custom code I have declared a variable thus:
Public Dim ParmValue As string = Parameters!Parm1.Value

What I want is this: When a user select a report, they will have to choose a parameter from a dropdown-list (created automatically when creating a paramete). The chosen parameter will be passed to the variable ParmValue which I use as one of the parametes in a text-box like this:
=code.InstanceName.MethodName(ParmValue)

InstanceName is the instance of a class from a dll I reference.
It works fine if I hard-code the paramter like this:
Public Dim ParmValue As string = "SomeString" instead of:
Public Dim ParmValue As string = Parameters!Parm1.Value

The error I get is this:
[rsCompilerErrorInCode] There is an error on line 0 of custom code: [BC30469] Reference to a non-shared member requires an object reference.

I don't know if I'm at all on the right track here.
Can someone tell me what I'm doing wrong?

Thanks
/Peter

Passing Batch Variable

Feb 8, 2008

Hi:

I'm not an expert with using batch files, or using them with SSIS, but I am trying to use two batch files in my SSIS package. I want the first one to map the first available drive on the server and pass that drive letter as an output variable to the package, and then to pass this variable to the last batch file and unmap.

I already have execute program tasks set up with a hardcoded drive letter, but that is not going to work as I don't know what drive letters will be mapped on this machine.

I did find sample code for using variables in a batch file that maps drives:




Code Snippet
@ECHO OFF

rem Map \serverfolder to the next available drive letter and save
the driveletter as DRIVELETTER
FOR /F "tokens=2" %%A IN ('net use * \serverfolder) DO IF NOT %
%A.==command. SET DRIVELETTER=%%A

rem Unmap DRIVELETTER
net use %DRIVELETTER% /del

rem Clear your env variables
set DRIVELETTER=





Questions:
1. Is this the type of code I want to use with the SSIS package?
2. How do I use the batch file with SSIS? I see the Execute Process Tasks has a "StandardInputVariable" and "StandardOutputVariable". Will these work?

Thanks,
Kayda

Is it possible to use a table's fieldname as an SQL variable?

i.e. can the below be made to somehow work:

---
The "user input" being any other chosen column/fieldname from the ContactDetails table (e.g. Street, City, Postcode, etc.).

i'm using Access and ASP - in case that makes a difference.

I have cursor that loops through a table (the table only contains columnnames of several tables) the cursor has a variable declared @columnname. when i run the following it works fine

now i want to get the min of each column name like so

select @columnname,min(mtr_5120),0,0,0
from temp_prt ------> this works for min(mtr_5120)
mtr_5120,34.5,0,0,0

now I want to generalize so I try to pass in the variable name and I do the following

select @columnname,min(@columnname),0,0,0
from temp_prt
(the columname (@columnname) exists in the table temp_prt)

but now i get an error
Msg 8114, Level 16, State 5, Line 29

Passing DatePart Variable To DateAdd()

May 14, 2008

When I call DateAdd(), I would like to pass a variable for the first parameter.

I wrote a little script that illustrates the problem, as well as the desired outcome I'd like to achive.

-- 1. Declare a "@DatePart" variable

DECLARE @DatePart VarChar(5)


-- 2. Assign a value to the "@DatePart" variable.

--

-- In this case, DatePart = 'month',

-- But we may choose day, week, or year.

--

-- SELECT @DatePart = 'day'

-- SELECT @DatePart = 'week'

SELECT @DatePart = 'month'

-- SELECT @DatePart = 'year'


-- 3. Attempt to add 1 month to today's date.

--

-- Depending on the value of "@DatePart",

-- add 1 day, week, month, or year to today's date

--

-- 3.1 This throws "Invalid parameter 1 specified for dateadd."

select DateAdd(@DatePart, 1, GetDate())


-- 3.2 This addes one month to today's date (as I hoped 3.1 would do)

select DateAdd(month, 1, GetDate())

Loop By Passing Variable Into Query

Nov 2, 2007



Hi all,

I'm have created a data flow that uses an OLEDB source with a SQL Query. In the WHERE statement of this query is a condition for the storecode. I want to figure out how to create a loop that will cycle through a list of storecodes using a variable which is passed to the dataflow in turn to the OLEDB source's query and runs through the process for each store.

The reason i'm using a loop is because there are about 15 million records that are merge joined with 15 million others which is causing a huge performance problem. I'm hoping that by looping the process with one store at a time it should be faster. Any ideas would be greatly appreciated.

Problem Passing A Variable To A Stored Procedure

I've got stored procedure:
  ALTER PROCEDURE [dbo].[dropmyValue](@dropVal Char OUTPUT)ASEXECUTE('ALTER TABLE [dbo].[tbl1] DROP CONSTRAINT ' + @dropVal)  That gets it's value from a GridView.SelectedValue:
Protected Sub GridView1_SelectedIndexChanged(ByVal sender As Object, ByVal e As System.EventArgs)        If GridView1.SelectedValue.ToString <> "" Then            Dim cs As String = ConfigurationManager.ConnectionStrings("ConnectionString").ConnectionString            Using con As New SqlConnection(cs)                con.Open()                Dim cmd As New SqlCommand                cmd.Connection = con                cmd.CommandType = CommandType.StoredProcedure                cmd.CommandText = "dropmyValue"                cmd.Parameters.Add("dropVal", SqlDbType.Char)                cmd.Parameters("dropVal").Direction = ParameterDirection.InputOutput                cmd.Parameters("dropVal").Value = "DF_" + GridView1.SelectedValue                Label2.Text = cmd.Parameters("dropVal").Value                cmd.ExecuteNonQuery()            End Using            GridView1.DataBind()        End If    End Sub 
Label2.text shows that @dropVal is "DF_xxxxxxxx" and is the name of the Constaint to be dropped (when I comment out "cmd.ExecuteNonQuery" and run it), but the error I get is that
" 'D' is not a Constraint ". I don't know if this is a sqldbtype problem, but I've tried different ones and evidently only the first character "D" is getting read, or passed to the stored procedure.
Any help would be appreciated.

Passing '% Variable %' To SqlDataSource Through E.Command.Parameters

Feb 23, 2008

 Hello all,I'm writing a site with one page that uses the session variable (User ID) to pick one user ID out of a comma separated list in the field Faculty. The default parameterized query designed in the SqlDataSource wizard only returns lines that contain an exact match:SELECT * FROM tStudents WHERE ([faculty] = @faculty) The query: SELECT * FROM tStudents WHERE ([faculty] LIKE '%userID%') works as I need when I hard code the query with a specific user ID into the SqlDataSource in the aspx page.  It will not work if I leave the @faculty parameter in it:SELECT * FROM tStudents WHERE ([faculty] LIKE '%@faculty%') e.Command.Parameters works to replace the @Faculty with a user ID, but again, adding the single quote and percentage sign either causes errors or returns no results.  I've tried several variations of:         string strEraiderID = "'%" + Session["eRaiderID"].ToString() + "%'";        e.Command.Parameters["@faculty"].Value = strEraiderID;no results are returned, not even the lines returned with the default select query.How do generate the equivalent of SELECT * FROM tStudents WHERE ([faculty] LIKE '%userID%') into the SqlDataSource? Thanks much!

Jun 11, 2008

Hi,

I am creating SSIS package which using Execute SQL Task to which I am supplying one .sql file code is

delete from Test where ID = @ID

I defined @ID variable to SSIS and also path where .sql file placed but i am not able to execute this package i am getting error like can not find C:@Path file......

As i got information that passing such variable to .sql you need ADO.net connection so I changed SQLSERVER Database connection string to ADO.net .... after that when i set hard core value for these variable i.e for @ID and @Path then it runs sccessfully but by setting parameter i am getting above error


Any suggestion that will be gr8 help for me

T.I.A

Passing Variable Into CREATE LOGIN Script

Sep 23, 2013

Need to create same login on 100s of servers using local admin login create on the OS. (for xp_cmdshell proxy setup)

Normal command works fine but I meed to make <svr_name> a variable.

CREATE LOGIN [<svr_name>DBALocalUser] FROM WINDOWS WITH DEFAULT_DATABASE=[master], DEFAULT_LANGUAGE=[us_english]
GO

When I try various efforts to pass in the <svr_name> portion it fails every time.

declare @cmd varchar(200),
declare @username varchar(50)
set @username = 'DBALocalUser'
set @cmd = ' CREATE LOGIN ['+@@servername+''+@username'] FROM WINDOWS WITH DEFAULT_DATABASE=[master], DEFAULT_LANGUAGE=[us_english]'

[Code] .....
