HowTo: Read/write Package Level Variables In Custom Task
Oct 13, 2006Hello all,
I have been struggling trying to read and/or write package level variables from within my custom task. I'd like to be able to get and set values from within the Execute method of my custom task. I have searched this forum and the books online and can't seem to find the answer. I thought maybe I could use an expression on my task (mapping the package variable to a custom task public property) but that doesn't seem to be working for me. I also would have thought I could use the VariableDispenser object from within my task but the collection is empty. I have 3 package level variables configured and can't seem to find a way to access them (with intentions of getting/setting). Could someone point me to a good doc or provide an example that may accomplish this? Thanks!
(I'm using package level variables as a means of passing simple information between tasks that are not using a DB, if there is a better way I'm open to suggestions.)

How To Access Package Variables In A Custom Task
Jul 3, 2006Hi Everyone,
I created a script task that uploads a file to a HTTPs site. The script task works well and now I want to turn this script task into a custom component...
I'm having problems on how to call the variables I have in the package, I already locked them for reading, but how am I suppose to access them and how can I put their values into strings so I can easily call them in the WebClient.UploadFile method?
Also, I am very new to custom tasks in SSIS.. and would appreciate if anyone of you can send me something (code, link, etc.) of a very simple custom task without any form or properties, that I can try to study.
Basically, what I want my custom task to do is,
1. Read the varialbes in the package.
2. use the variables values as input in my WebClient.UploadFile("varURLstring", "PUT", "varFilePath")
as you can see, my custom task is really simple... but I'm a noob here and I don't know where to go.
Thanks in advance,
Kervy
Custom Task: How To Access/modify The Variables Of A Package
Feb 1, 2007Hi,
I'm trying to simplify the deployment process of my project. I already had some troubles with the config files but lets say I solved that issue. I'm going to read a flat file and set the variables of my packages from this file. I was thinking to use a Script Task to do that but I will need to copy this task in every package (I have at least 30). So if I want to make some change this will be painful.
Then, I came up with the idea of creating a Custom Task called Config File Task. I'm working on this but I got stuck trying to get the variables from the package that is running my Config File Task.
This is the code I had in the Script Task:
Dim streamReader As New StreamReader(Dts.Variables("ConfigFilePath").Value.ToString)
Dim line As String
Dim lineArray As String()
Dim variableName As String
Dim variableValue As String
Dim readConfigurations As Boolean = False
While (streamReader.Peek() <> -1)
line = streamReader.ReadLine()
If line = "[CONFIGURATIONS]" Then
readConfigurations = True
ElseIf line = "[/CONFIGURATIONS]" Then
readConfigurations = False
Else
If readConfigurations And line <> "" Then
lineArray = line.Split("|".ToCharArray())
variableName = lineArray(0).Trim()
variableValue = lineArray(1).Trim()
If Dts.Variables.Contains(variableName) Then
Dts.Variables(variableName).Value = variableValue
End If
End If
End If
End While
Dts.TaskResult = Dts.Results.Success
All I want to do is set the variables that exists in each package from the config file. In my UI Class (ConfigFileTaskUI.cs) I can have access to the variables via the TaskHost which is passed as an argument of Initialize() method.
Any thoughts? I'd really appreciate some help!
P.S. I've been working on this for 2 days!
Execute DTS 2000 Package Task Editor (Inner Variables Vs Outer Variables)
Sep 4, 2006 Hi,
I am not comfortable with DTS 2000 but I need to execute a encapsulated DTS 2000 package from a SSIS package. The real problem is when I need to pass SSIS variables to DTS 2000 package. The DTS 2000 package have 3 global variables that I can identify on " Execute DTS 2000 Package Task Editor - Inner Variables ". I believe the SSIS variables must be mapped on " Execute DTS 2000 Package Task Editor - OuterVariables ". How can I associate the SSIS variables(OuterVariables ) to "Inner Variables"? How can I do it? Much Thanks.

Read All Variables In A Script Task W/o Enumerating Them
Sep 19, 2007I'm having trouble with my configurations. All of my configurations are targeting variables and the various properties are all set to expressions containing the targeted variables. I would like (during debugging) to dump out all of the variables.
Is there a way to access all variables from a script task? It looks like you have to enumerate the variables you want in the ReadOnlyVariables or ReadWriteVariables properties. I'd rather not miss one by forgetting to list it.
Accessing A Package's Variables From Within A Custom Log Provider...or Not...
Feb 21, 2007Hi,
Given that Task.Validate() exposes the package's VariableDispenser, but LogProviderBase.Validate() doesn't...

http://msdn2.microsoft.com/fr-fr/library/microsoft.sqlserver.dts.runtime.logproviderbase.validate.aspx
...I guess that simply means that I can't access a package's variables within a custom log provider? Can anyone comment/confirm? Any other options/routes to achieving the same..?
We live in hope,

Reading Package Variables From Custom Log Provider
Oct 1, 2007I am interested in determining if package variables can be read from a custom log provider. I am able to pass the values into the custom log provider using an expression in a custom connection manager. My intention is to used the values of these variables upon package failure so I can capture the context of the failure. Unfortunately, if the value of the variable is changed at runtime, this update is not reflected in the custom log provider.
Is it possible to get direct access to the package variables from the custom log provider?
Thanks,

Oct 27, 2006Hello All,
I have searched on this forum for a similar question but couldn't find it so I apologize if this has been asked. If so, I'd greatly appreciate a link to the question. I have created a custom task and am trying to read an xml package configuration file within my custom task. To be more specific, I have added an ADO.Net Connection to my database onto the package and have generated the appropriate tags within my package's configuration xml file. I'm not seeing the classes I should use to access the configuration file of the package I've created. Does anybody have any ideas how I can accomplish this or a link to a document that might cover the material? Thanks!

Using Package Variables As Parameters In Execute Sql Task
Feb 23, 2006Hi,
I need to run an SQL command, in which one of the fields is based on the current time, represented as a string in a specific format.
I used a script task to create the string from the current time, and store it in a package variable named "newDate". Later, in the execute sql task, I have the following update statement: "update table_1 set field_1 = ?" (OLE DB connection is used)
and in the parameters mapping I set parameter 0 to the string package variable "newDate".
The problem is that on runtime, the sql executes with the default value of the variable - i.e. it doesn't take the new value.
I checked it and placed another script task after the first one, that simply tries to read the variable "newDate" and print it to screen, but even here the default value is used.
how can I use the new value of the variable?
thanks.
Package Variables Passed To Execute SQL Task
Aug 14, 2007Hi,
I am having trouble getting the Execute SQL Task to recognize the package-level variables in an SSIS package. The tasks fail execution. The package contains three Execute SQL tasks and none of them receive the variables. However, when I replace the '?' in the code with the variable values they execute fine. These are the steps I have taken thus far:
Made sure the three variables are package level.
Verified I'm using an OLE DB valid connection.
Verified the variables are properly mapped in the parameters mapping section of the task properties.
Tried all 4 types of variable to parameter mapping (even though '?' in the query and '0,1,2..' in the name should work).
Changed the Bypassprepare property to 'True'.
Breakpoints and watch windows to verify the variable values.
I actually tried the simple tutorials on a one-liner SQL statement that uses variables, but had the same problem. I know there must be something simple that I'm missing here, but any info would be greatly appreciated!
Thanks!

View 6 Replies View RelatedExecute Package Task: Setting Child Variables
Feb 13, 2007Hi,
Let's say I have a package taking as parameter "InvoiceID". I want to execute this package as a child in another package. The parent package gets the list of invoices to produce and calls the child package for each entry of the list.
How do I pass the InvoiceID to the child? I know I can use the parent's variables from the child but I don't want the child package to be dependant on the parent package. For example, I might want to execute the "child" package as a stand-alone in development (providing it with a predefined InvoiceID). I might also want to call the same child package from another parent package with other variable names.
What I would like to do is "push" the value instead of "pulling" it. I know it's possible using the command line and the /SET option (ex.: /SET Package.Variables[InvoiceID].Value;' 184084)... Is it possible using the Execute Package Task?
Thanks
Custom Task: How To Access/modify The Expression Collection Of A Package
Feb 6, 2007Hi,
I created a Custom Task which it has a Property called ConfigFilePath. I'm overriding the Validate() method from Task. I want to throw an error if my property ConfigFilePath is empty and if the expression for this property is empty. So far, I can check if the property is empty but I don't see how I can access the Expressions Collection of my Custom Task.
Any thoughts? I'd appreciate your help.
BCP Task And Dynamic Import And Export Of A File Via Package Variables

I have a global database called ETL Configuration for all my SSIS packages that uses a single table. So I can create three global variables

[ConfiguredValue] [nvarchar](255) COLLATE Latin1_General_CI_AS NULL,
[PackagePath] [nvarchar](255) COLLATE Latin1_General_CI_AS NOT NULL,
[ConfiguredValueType] [nvarchar](20) COLLATE Latin1_General_CI_AS NOT NULL
) ON [PRIMARY]
Here is the data I would put in here
ConfigurationFilter = 'MySSISPackageName'
ConfiguredValue = 'D:IPCSextract.csv'
PackagePath = 'Package.Variables[User::gsFileName].Properties[Value]'
ConfiguredValueType = 'String'
ConfigurationFilter = 'MySSISPackageName'
ConfiguredValue = 'D:ipcsqueryextract.xml'
PackagePath = 'Package.Variables[User::gsFormatFile].Properties[Value]'
ConfiguredValueType = 'String'
ConfigurationFilter = 'MySSISPackageName'
ConfiguredValue = 'ipcs_wvg.dbo.extract'
PackagePath = 'Package.Variables[User::gsTableName].Properties[Value]'
ConfiguredValueType = 'String'
--Database connection info
ConfigurationFilter = 'MySSISPackageName'
ConfiguredValue = '.mssql2005'

ConfiguredValueType = 'String'
ConfigurationFilter = 'MySSISPackageName'
ConfiguredValue = 'MyDatabaseName'
PackagePath = 'Package.Connections[MyDatabaseName].Properties[InitialCatalog]'
ConfiguredValueType = 'String'
I have looked at lots of options to automaticly create SSIS packages and have a hunch that that simple can be better: All these solutions look way to complex to what I want to achieve--

SQL 2012 :: Passing Record Counts From Execute Task In SSIS To Package Variables
Mar 4, 2014I've got a package in SSIS 2012 that has an Execute SQL task in the control flow level.
The SQL in question does an Upsert via the SQL merge statement. What I want to do, is return the count of records inserted and records updated (No deletes going on here to worry about). I'm using the output option to output the changed recs to a table variable.
I've tried returning the values as:
Select Count(*) as UpdateCount from @mergeOutput where Action = 'Update'
and
Select Count(*) as InsertCount from @mergeOutput where Action = 'Insert'
I've tried setting the resultset to both Single rowset and Full rowset, but i'm not seeing anything returned to the package variables I've set for them (intInsertcount and intUpdatecount).
Dynamically Pass Table Names And File Names To IS Package

Custom Task - Custom Property Expression
Aug 16, 2006I am writing a custom task that has some custom properties. I would like to parameterize these properties i.e. read from a varaible, so I can change these variables from a config file during runtime.
I read the documentation and it says if we set the ExpressionType to CPET_NOTIFY, it should work, but it does not seem to work. Not sure if I am missing anything. Can someone please help me?
This is what I did in the custom task
customProperty.ExpressionType = DTSCustomPropertyExpressionType.CPET_NOTIFY;
In the Editor of my custom task, under custom properties section, I expected a button with 3 dots, to click & pop-up so we can specify the expression or at least so it evaluates the variables if we give @[User::VaraibleName]
Any help on this will be very much appreciated.
Thanks
How To Design A Package With Variables So That I Can Run It By Dos Command Assigning Values To Variables?
Jan 24, 2006Hi,
I would like to design a SSIS package, which have couple of variables. It loads a xls file specified in a variable [varExcelFileFullPath] .
I will run it by commands: exec xp_cmdshell 'dtexec /SQL ....' (pls see an example below).
It seems it does not get the values passed in for those variables. I deployed the package to a sql server.
are there any grammar errors here? I copied it from dtexecui. It worked inside Dtexecui not in dos command.
exec xp_cmdshell 'dtexec /SQL "LoadExcelDB" /SERVER test /USER *** /PASSWORD ****
/MAXCONCURRENT " -1 " /CHECKPOINTING OFF /REPORTING EW
/LOGGER "{6AA833A1-E4B2-4431-831B-DE695049DC61}";"Test.SuperBowl"

Table Names And Variables
Nov 14, 2005I have a cursor which populates a variable with the name of each user table within my DB.
I'm trying to copy the tables one at a time by using a command like this:
SELECT * INTO @NewTable FROM @OrigTable
Query analyzer tells me that there's incorrect syntax near the keyword 'INTO'.
This seems fair enough to me as I assume it's trying to put the data into the variable rather than the table name which is held within the variable. Does any know how I can get around this?
Are there any alternative ways of copying the table structure (preferable without the data)?
BTW both variables are of type char(100)
Using Variables For Object Names
Oct 7, 2005I am writing an sproc for creating a table, but I don't know how I can use parameter values as object names (for example the name of the table needs to be [@sFile1+'_'+@sLinkName+'_'+@sFile2']. It seems that I could concatenate my whole CREATE TABLE string into a single variable and use EXEC to run it, but I'd prefer to be able to do it in the context of the sProc (I read that EXEC always has the current user's permissions). What is a good technique?
CREATE PROCEDURE dbo.CreateLinkTable
@sFile1 varchar(50),
@sFile2 varchar(50),
@sLinkName varchar(50)
AS
CREATE TABLE [@sFile1+'_'+@sLinkName+'_'+@sFile2]
(
[GID_ID]uniqueidentifierROWGUIDCOLNOT NULL,
['GID_'+@sFile1]uniqueidentifierNOT NULL,
['GID_'+@sFile2]uniqueidentifierNOT NULL,
CONSTRAINT ['LNK_'+@sFile1+'_'+@sLinkname+'_'+@sFile2]
FOREIGN KEY(['GID_'+@sFile2])
REFERENCES [@sFile2](GID_ID)
ON UPDATE NO ACTION
ON DELETE NO ACTION
NOT FOR REPLICATION,
CONSTRAINT ['LNK_'+@sFile2+'_'+@sLinkname+'_'+@sFile1]
FOREIGN KEY(['GID_'+@sFile1])
REFERENCES [@sFile1](GID_ID)
ON UPDATE NO ACTION
ON DELETE NO ACTION

Using Variables To Select Column Names
Oct 20, 2006Hi
I've tried declaring and setting variables in my sql statement and then trying to use them instead of defining a column directly - sorry quite hard to explain, i'll do a simple example
eg
DECLARE @column
DECLARE @value
SET @column = 'col1'
SET @value = 'bloggs'
Select * FROM table1 WHERE @column = @value
It keeps returning no results even though i've tried
Select * FROM table1 WHERE col1 = 'bloggs' -- which returns results
I realise its the column which is not being selected, but there must be a way by using a variable?

Use Of Variables In Table Names And Fields
Jun 22, 2006Hi, I am new to using SQL for anything more in depth than querying and reporting.
I am trying to create a series of SQL scripts which will be used across several customer sites so need to be easily customisable. What I want to do is have all of the table names, field names and customisable items handled by variables which will be declared and set at the beginning of the script, making them easy to find and change. The problem I am having at the moment is with creating a new table using variables for table name and field names, can anyone help?
quote:
DECLARE
@a_tmptbl varchar(15),
@a_fieldid1 varchar(15)
set @a_fieldid1 = 'newFieldid'
set @a_tmptbl = 'newTable'
create table @a_tmptbl ( @a_fieldid1 varchar(15), value float, counter INT);
insert into @a_tmptbl values ( "foobar", 21.76, 1);
select * from @a_tmptbl;
The error I am getting is:
quote:Server: Msg 170, Level 15, State 1, Line 8
Line 8: Incorrect syntax near '@a_tmptbl'.
Server: Msg 137, Level 15, State 1, Line 10
Must declare the variable '@a_tmptbl'.
Server: Msg 137, Level 15, State 1, Line 12
Must declare the variable '@a_tmptbl'.
Any advice would be gratefully accepted

Passing Variables And Column Names To EXEC
Oct 9, 2007Hello, I'm quite new to T-SQL, but since I'm trying to create a statistics page on database contents (Counting savesets in Enterprise Vault saveset Databases) I prefer to do the coding in the databases.
I create temp tables for the distinct partitions in the saveset table. Then I pass 2 variables to the EXEC function, but it seems unable to pass the ['+@idpartition+']-variable as a value:
Declare @EVBase varchar(20)Declare @IdPartition INTSet @EVBase=(SELECT EVMbxName from Servers) Set @IdPartition=(SELECT TOP 1 Dist_Partitions FROM TEMP_EV1)EXEC('SELECT COUNT (IdPartition)FROM ['+@evbase+']..SAVESET SS LEFT OUTER JOIN SavesetStore SSS ON SS.SavesetIdentity = SSS.SavesetIdentityWHERE [IdPartition] = ['+@idpartition+'] AND StoreIdentifier IS NULL')
Server: Msg 207, Level 16, State 3, Line 2Invalid column name '0'.
If I change the last line to: WHERE [IdPartition] = 2 AND StoreIdentifier IS NULL')The script runs fine - but I need the value from the table. Any help will be appreciated.
Best regards, Tim
Variables For Table Names In Stored Proc
Nov 8, 2004i'm trying to create a stored procedure that takes 2 input parameters (taken from a querystring): a table name, and a number that needs to be checked whether it exists within that table. yes, i have different tables, one for each forum, so they will have the same structures -- i'm figuring this approach will result in faster page-load times if the tables have less in them. if everyone here tells me that having one table for all the forums will work fine, i'll just go that route, but if not, here's my procedure:
Create Procedure VerifySubjectNum
(@forum_ID VARCHAR(10), @subject_num INT)
As
If Exists
(SELECT subject_num FROM @forum_ID WHERE subject_num = @subject_num)
Return 1
Else
Return 0
when i try to create this, i get an error saying @forum_ID must be declared... why doesn't it work within the select for the EXISTS?
How To Read A Set Of Rows Into Session Variables? C#

Some of the modifications will include comparisions between two columns and if certain field is NULL then I want to get the value from the other one I was comparing to. When using conditional splits, I only get the rows to be redirected so that I can do whatever next. However, I want like use the variables as a storage so that I can put the value of one of the two columns in this variable which will be actually loaded into the destination finally. Any help?

I found one post from the past asking this question, but didn't see an answer, so I am hoping someone can shed some more light on it:
I am writing a custom log provider in C#. Is it possible give this custom log provider access to the variables collection (via a variabledispenser object)? First glance at the log provider classes would tell me that this is not possible, though I would like confirmation. Also, if I am correct in thinking it is not possible, what was the reason for leaving this out?
Thanks!
