Saving Custom User Interface Options In Contained In Complex Datatypes
Oct 8, 2007
I'm developing an custom dataflow transformation task that involves mapping of columns between multiple inputs and outputs. All the mappings are stored in a dataset. At first I thought to store this to an variable but after reloading bids I get an schema not found on xml for the stored dataset. Then I tried to put the dataset into an custom property but that seems to only take strings.
So how do I save the info on the mappings contained in my dataset (as that is most easy while using a datagrid to display mappings) in the package preferably in a way that is not visible to the user.
In short: What is the proper way to save complex datatypes in a custom dataflow task using a custom ui?

small explain
this fonctin-generate daily shift pattern 1,1,2,2,3,3,4,5,...

so like this if the employee on Thursday start a series value 2 OR 3 the employee must to end it on the week-end from Thursday until Sunday morning
so my friends
can someone save me
how to do this
Code Block
-- need a list of employee ids with a basedate set to when they start with shift_code=1, unit=1
-- this is a minimal tale to show the format
-- extra columns could be added with other info (e.g. name)
create table empbase (
empid int,
basedate datetime
)
-- fill with test data
insert empbase (empid,basedate) values (12345,'2007/1/1')
insert empbase (empid,basedate) values (88877,'2007/1/5')
insert empbase (empid,basedate) values (98765,'2007/1/20')
insert empbase (empid,basedate) values (99994,'2007/6/5')
go
-------------------------------
create function shifts (
@mth tinyint,

returns
@table_var
table (
empid int,
date datetime,
shift_code int,
unit int)
as

Is it possible to change the owner of a User Defined Dataype? I've
recently had to change the owner of one of my databases and the
tables from a specific user to 'dbo'. The UDD's are the only objects
I am unable to change the ownership of.
Any suggestions anyone?
Thanks for any advice!

Hi,
I used user defined datatype but when I tried to change the length of the datatype I found out I could not modify the length by going to property of user defined datatype or I could not drop it without dropping the dependent tables. I got a problem. Anybody can help?
Thanks,

Hi,Using VB.net I have created a custom object (hope my terminology is correct here), it’s just a class that defines a few string, integer, and hash table variables. After creating an instance of this class and populating it with data I need to be able to store this instance of my object in a sql server data base table. How do I do this? I saw an article that used the image data type to achieve this (code was in java unfortunately) is this the correct approach. Could you please give me some code examples
Thanks

I am looking for some advice regarding saving custom component data when saving packages.
For custom "properties", this is not an issue, as saving the package will save these properties. Howver, I also have information for each column (besides the properties that columns provides, like Name and DataType) that I need to save if a package were to be saved, and right now it does not save because I am using my own objects to store the data.
I am wondering as to how I can save this information. I have looked up on serialization, but I would like to know if there is another way besides serialization to save this inforamtion as I'd rather not save this to a seperate file.
Thanks

I downloaded SQL Server Express 5.0 and would like to know - must I open SQLServer through a studio like SQL Server Management Studio Express, or can it open on its own? Does it come with a GUI inside it?
I clicked Start/All Programs/Microsoft SQL Server 2005 and only submenues were displayed, not the server itself. The submenues were
Configuration Tools
SQL Server Management Studio Express.
Thanks.

Hi Folks,
I have a task I wrote which does not always update the property value (as seen in the properties pane)
Basically, change something on the form, then update the task host property with:
this.taskHostValue.Properties["Duration"].SetValue(this.taskHostValue, Convert.ToInt32(spnDuration.Value));
Stepping through this, it does exactly what it is supposed to. Having a look at the property value, it confirms it has changed.
Reopening the UI and resetting all the controls returns the expected results.
The package however does not realise it has changed. There is no * next to the package name in the top tabs.
As long as the package thinks it is unchanged, SaveXML does not get called either so the tasks do not persist.
Changing the value on the properties pane works fine though.
The frustrating thing is this is slightly random. Slight in the sense that sometimes it works but most of the time it does not.
The sample code I used was the MS download IncrementTask (Which works BTW) so I can't see it as being a VS / SSIS bug but rather something I am / am not doing. 3 tasks I have written all behave the same. I have to "nudge" them before savign the package.
Any ideas what the problem might be?
TIA
Cheers,
Crispin

Hello everybody,
please advice: what is the fastest standard method of user interface access to SQL database? I am looking for fast display of one master record plus related dependent records, plus fast scrolling through master records with display of dependent records as fast as posible. Perhaps a standard problem with standard solution? At current state of matters, I am still much slower then with my old Access97 database.
thanks for any advice,

Using SQL Server Reporting Services, we're designing an executive reporting interface for a handful of high-level managers who need no more that a dozen reports.
What's the best user interface for them where they would choose the report they need?
- The SSRS Report Manager web page?
- A SharePoint page (integrated with SSRS)?
- A report menu within an existing application?
- Anything else?

I have a SSIS package which takes excel spreadsheets (exported from MS Project) and imports them into tables in my database. I have each step of my control flow set up with "On Success" so it only continues if the previous step was successful.
My next step is to create a asp.net page and/or web part so that I can have my user click a button to launch this SSIS and import this data. I have seen articles on how this could be done via code - so I assume it can be done. But what I cannot find is how alert the user if an error has occured in the execution of the SSIS.
How can you alert a user that a package you executed though vb.net in the front end errored?
Could I build something in to the OnError handler that returns the error and have that error returned to the front end App??
Any insight/examples for this would be much appreciated.
Thanks.

Hello,I would like to know if it is possible to create a form in Access2000,which would function like a calendar for 8 operating rooms inhospital, showing which hours are those closed for a specific date.For this intersection I would like to be appeared the name of thedoctor, the name of the patient and the kind of operation.Furthemore I would like this intersection to be marked in the calendarwith a colour, showing that this room is closed for that time.The data for this form are going to be extracted from a table storedin SQL Server 2000.Generally the whole application is stored in SQL Server( storedprocedures, tables, diagrams etc.)1)How this can be done? Is this going to be through VB or not? Can Imake a template in Excel spreadsheet put it in a formand apply code on it?I would like also to make forms(in Access) for user-entry data thatwill use stored procedures of SQL Server with pushing the OK button.The stored procedures would take as arguments the user-entry data fromtheforms.I thought to make a pass-through query which would use a VB functionand would take as arguments the user's valuesand after would pass these values in the stored procedures.2)Can this be done through the pass-through query, that is SqlServer "understands" VB or better Access pass-through query processthe VB commands before be connected with the Sql Server?What do you think of this as an idea?My problem is that I really don't know how to combine VB code withTransact Sql code.Can you give an example or any ideas where I can find the relativeinformation?Thanks you in advance.

Hello, does anyone hate the new interface where you
manage the Table Relationships, Indexes, and etc?
I hate it a lot for these reasons.
1) Dialog window cannot be resized (really really annoying)
2) The Table-Relationship configuration dialog window is not as convenient to use as SQL Server 2000 Enterprise Manager.
I hope this is the correct place to provide feedback and
I hope this will get modified a bit in the next service pack (or) update....

I execute a pretty big sql query which joins multiple tables and I reviewed indexes on all these tables. I am happy with the result when I run the query using SSMS in the server locally i.e., where my SQL Server database is installed. It takes 4 seconds to get around 17000 records. If I run the same query in a network or from my desktop using SSMS i.e., i connect to the above mentioned SQL Server using SSMS, it takes more than 60 seconds. Not sure how to solve this. If someone could help me, it will be of great help.
Thanks.

One of the configuration options that can be set for the server is called "user options". User options contains sub-options such as ansi_warnings, ansi_padding, ansi_nulls, arithabort, etc..
Using T-SQL, how are these set?
sp_configure 'user options', @configvalue = 'value'
go
reconfigue with override
go
i.e. Are the individual option values summed. Say I wanted to set ansi_warnings (whose value is 8) and ansi_nulls (whose value is 32) on and all other user options off. Then is my @configvalue 40?
Sorry, but I don't feel BOL is clear on how to set these options.
TIA Gary

Hello everyone,
i'm using a foreach loop container to read a group of excel files and pass their information to a Sql Server database. The process runs well but sometimes there could be some excel files that may not be processed correctly so i'm using transacctions to continue to process on the other files, But i'd like to generate a message everytime an excel file is or not processed. I thought that i could generate a flat file to do it, but is there any other way to accomplish this? I'm also generating a log file (on xml format), but It seems too much information for an end-user.
any suggestions?
regards.

I've been playing around with building custom components for SSIS. I've been doing workflow for years (using Java and Oracle). The company I worked for had a framework for publishing data that allowed for user interaction. That's something I'd love to be able to do in SSIS.
Is it possible to create a custom task that interacts with the user at runtime? So, the user starts the SSIS package. At some point, the process pops up a dialog (Windows Form) that asks the user to set a date using a calendar control.
Any thoughts?

Hi,
I want to recalculate some columns in a custom component, due to a formula using a single column as factor. What will be the best way to let the user choose the single column (factor) beneath the columns to work with.
Is there a way to use customproperties other than strings. DropDowns for example. If so, do you know a tutorial oder code snippet?
Thanks

Hi Guys,
I am trying to automate a basic task using SQL Server 2005 Express.
Currently I have a query script that I run and then save the results as a CSV file. I need to do this on a daily basis and so I am looking to find out how best to go about this. There are a multitude of third party tools that claim to be able to do this - can anyone recommend this or enlighten me of the best way to set up this automation.
All ideas gratefully received!

I have web forms with about 10-15 optional search parameters (fields) for a give table. Each item (textbox) in the form is treated as an AND condition.
Right now I build complex WHERE clauses based on wheather data is present in a textbox and AND each one in the clause. Also, if a particular field is "match any word", i get a ANDed set of OR's. As you can imagine, the WHERE clause gets quite large.
I build clauses like this (i.e., 4 fields shown):
SELECT * from tableName WHERE (aaa like '%data') AND (bbb = 'data') AND (ccc like 'data%') AND ( (xxx like '%data') OR (yyy like '%data%') )
My question is, are stored procedures better for building such dynamic SQL clauses? I may have one field or all fifteen. I've written generic code for building the clauses, but I don't know much about stored procedures and am wondering if I'm making this more difficult on myself.

I'm writing a custom source component that reads data from a SharePoint list with dynamic mapping to output columns. It's my first custom component and it's based on several samples and tutorials from Internet
Output columns are not created by the component itself, they must be added by user at design time. The component makes dynamically an association between SharePoint fields and available output columns at run-time (based on an mapping table).
I made a very basic skeleton and I encounter a problem when I add a column to output: it has no datatype and when I try to set one I have an the error Property value is not valid, The component xxxxxx does not allow setting output column datatype properties.

Hi,
I am creating a custom transformation component, and a custom user interface for that component.
In
my custom UI, I want to show the custom properties, and allow users to
edit these properties similar to how the advanced editor shows the
properties.
I know in my UI I need to create a "Property Grid".
In
the properties of this grid, I can select the object I want to display
data for, however, the only objects that appear are the objects that I
have already created within this UI, and not the actual component
object with the custom properties.
How do I go about getting the properties for my transformation component listed in this property grid?
I am writing in C#.

Hi,What I am trying to do is to get the new ID for every record is inserted into a table. I have a For...Each statement that does the loop and using the sqldatasource to so the insert. <asp:SqlDataSource ID="SqlDataSource1" runat="server" ConnectionString="<%$ myConnectionString%>">

Dim sqlSelect As String
Session("Waste_Profile_Num") = 2

For Each dr As Data.DataRow In dv.Table.Rows

Session("NewID") = e.Command.Parameters("@NewID").Value.ToString
End Sub What I have done so far is to display the new id and I am going to use that return id later. However, the first time through the loop, I am able to get the new id but not the second time. So, I wonder, how do I every single new id each time the INSERT statement is executed?STAN

I would like to perform an audit of weak passwords, which is well documented for sql users. Using the same methodology, I should be able to audit weak passwords for contained users. To accomplish this, I must be able to find the location of the password hashes for the contained users.
I have looked at sys.syslogins and sys.sql_logins, which both have the password hash for server level users, but not contained users. I was able to find sys.sysusers, which does contain contained users, but no password hash.
What is the location of the password hashes for contained users?

I know that anything in a CDATA section will be ignored by an XML parser. Does that hold true for the SSIS XML Source?
I am trying to import a large quantity of movie information and all of the reviews, synopsis, etc are contained in CDATA. example:
<synopsis size="100"><![CDATA[Four vignettes feature thugs in a pool hall, a tormented ex-con, a cop and a gangster.]]></synopsis>
Sounds like a good one, no?
The record gets inserted into the database however it contains a NULL in the field for the synopsis text. I would imagine that the reason for this would fall at the feet of CDATA's nature and that SSIS is ignoring it.
Any thoughts would be appreciated. Thanks.
