Run Custom SQL Commands On Every Column
Dec 13, 2007
Hi,
I am reading data from a Excel file. The first Row in the Excel file are the column names. The first row is a Time value. The other rows are only numeric values.
Sample of Excel File:
Timestamp SourceColumn1 SourceColumn2
12/12/2007 12:00 AM 30 20.4
12/12/2007 01:00 PM 35 21.2
12/12/2007 02:00 PM 32 22.5
.
.
.
What I now have to do is to extract the numeric values for every column and write the value at each row at the timestamp (given in the first column) to a database.
This means I have to run a SQL command on every column and every row.
Example:
#Processing Row 1
INSERT INTO Table VALUES (destinationcolumn1, destinationcolumn2, timestamp) VALUES (sourcecolumn1, valueatcurrentrow, timestampatcurrentrow)
INSERT INTO Table VALUES (destinationcolumn1, destinationcolumn2, timestamp) VALUES (sourcecolumn2, valueatcurrentrow, timestampatcurrentrow)
#Processing Row 2
INSERT INTO Table VALUES (destinationcolumn1, destinationcolumn2, timestamp) VALUES (sourcecolumn1, valueatcurrentrow, timestampatcurrentrow)
.
.
.
Does anyone know how to implement this in Integration Services?
Regards

I'm building a simple webform, except Visual Studio and my service provider have combined to drive me nutty.
First, I MUST use an ODBC connection to my remote SQL Server do to some unknown configuartion problem. I've been playing with Visual Studio for only a month, so normally when something goes wrong I can go look in the mirror and find the culprit. This is different. I've got a totally functional web form with a SQL Connection, but when I try to change it to an ODBC Connection, I get the following error.
An OdbcParameter with ParameterName '@CertHolder' is not contained by this OdbcParameterCollection
My coding is fine because I stole it straight from the walkthrough and it works. But the specifications that Visual Studio provide are quite suspect. Please note the failure to include some key "@" signs.

Excuse me if my terminlogy is inaccurate, i'm a .NETer that's new to SQL.
I was wondering if it's possible to reference a column in the WHERE CLAUSE that has been customily defined in the SELECT statement
for example
select employeeID, case when JobCode = 'A' then 'Accountant'
case when JobCode = 'C' then 'Consultant'
case when JobCode = 'B' then 'Biller'
End as JobType
from Employee
where JobType is not null
This does not work, and saids JobType is an invalid column name. Basically, what I want is to display the jobtype of the employee but i also want to only display the employees that are Accountants, consultants and billers.
Is this possible and what would be the best way of doing this?
I do not seem to be about to reference JobType in the WHERE statement.

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#.

creating a custom column that will put a list of 5 values for each unique value(or in this case Employee).
So I have a Employee table were I pull a list of all active employees -
Example -
024Swanson, Ronrswanson@tv.com
026Donaughy, Jackjdonaughy@tv.com
028Scott, Michaelsmichael@tv.com
What I want to do is add a column that has 5 values and create a row for each value
I want it too look like this -
024Swanson, Ronrswanson@tv.com a
024Swanson, Ronrswanson@tv.com b
024Swanson, Ronrswanson@tv.com c
024Swanson, Ronrswanson@tv.com d
024Swanson, Ronrswanson@tv.com e
[Code] ....
Currently all my query looks like is this -
SELECT EmpID, LastFirst, Email
FROM dbo.EmpList
WHERE (Active = 1)

Does anyone know how to get destination coulmns to show up in the advanced editor for a custom component? I have a custom flat file destination component that builds the output based on a specific layout. It works as long as the upstream column names match my output names. What I want is to allow non-matching columns to be mapped by the user as they can in a stock flat file destination. The closest that I have been able to come is to get the "column mappings" tab to show up and populate the "Available Input Columns" by setting ExternalmetadataColumnCollection.IsUsed to true on the input. The problem is that the "Available destination columns" box is always empty. I have tried the IsUsed property on the output and pretty much every other property that I could find. On the Input and Output properties all of my columns show up under the output as both External and Output columns. Is there a separate collection for "destination" columns that I can't find? It's getting a little frustrating, is this something that can be done or do I have to write a custom UI to make it happen?
Thanks!

I'm building a custom component and UI and am a bit confused on where I
need to create and/or set custom column
properties?
My UI will have a datagrid with three
columns: 1) a check box to select a column for use by the component, 2)
the input column name, and 3) a "differentiator" checkbox that indicates
an extra property about some of the columns that have the first column
checkbox checked (For example, my component may be using five input columns, but
three of those need to be used in a slightly different
way.)
The problem is, I don't understand when or
where I'm supposed to create the custom property for the input
column. SetUsageType is where I've been thinking, but I don't
know if I'm supposed to be creating it for an input column or a virtual
input column. I'd appreciate any guidance.

This is trivial I'm sure but I'll be dogged if I can find someone who mentions how to do it. I am attempting to develop a Data Flow Transformation that appends a new column (a string value) into the current stream.
I have found plenty of references on how to replace an existing column but I'd really like to just add my new column in there. It doesn't need to be configurable, it can be a static column name. I'll take a solution that allows the column name to be set at design time, don't get me wrong but the magic I'm looking for is how to implement a new column in a stream.
Yes, I am well aware of the derived column task but I will be replacing a few hundred instances and I'd much rather just drag an item onto the designer than to drag a derived column, double click it, type in the column name, set the expression and then set the datatype, etc.
Anyone spare a moment to enlighten me?

Hi,
I am building a custom component have a IDTSCustomProperty90 property that can take the value 'True' or 'False'.
Depending on its setting, I want to include (or not include) a column in the output.
Any advice on how to go about doing this (with some sample code) would be much appreciated!
Here's how I'm declaring the property in ProvideComponentProperties()
IDTSCustomProperty90 IncludeErrorDesc = ComponentMetaData.CustomPropertyCollection.New();
IncludeErrorDesc.ExpressionType = DTSCustomPropertyExpressionType.CPET_NONE;
IncludeErrorDesc.Name = "Some Name";
IncludeErrorDesc.TypeConverter = typeof(Boolean).AssemblyQualifiedName;
IncludeErrorDesc.Value = Convert.ToBoolean(false);
Thanks in advance

I want to add a custom column in a select statement that has a value to true or false based on other criteria.
SELECT [ID], [Name], [Description], [EmpID], [Employed] FROM [Employees]
Now, in the above example there is no [Employed] Column in my table but I want it to show true or false based on whether or not [EmpID] equals a certain value.

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

I'm building a custom transform component. I want to mark some input columns as keys for deduplicating. In a similar way to the provided Sort component, I want to check those columns and allow pass-throughs (or not) for the others - so next to each input column name I need two checkboxes (1:use for dedupe; 2:include in output if 1 not checked). If a column is checked for use in the dedupe, I want some other attributes to be shown indicating how it will be used. How do I display the checkboxes to let users select which columns to include for deduplication, and then how do I add further attributes underneath (copying the Sort component's look) for selection?
Thanks in advance for guidance and pointers on this.

A month or so ago I instigated this thread- http://forums.microsoft.com/MSDN/ShowPost.aspx?PostID=243117&SiteID=1 which talked about how to conditionally add a column to my component depending on the value of a custom property. If the custom property is TRUE then the column should appear in the output (and vice versa).
Bob Bojanic said I should use the SetComponentProperty() method to do this and that is working pretty well. However, it bothers me that SetComponentProperty() could be called, the column will then be added, and then the package developer could press 'Cancel'. In this instance the value of my custom property would be inconsistent with the presence of the extra column.
How do you get around that?
Thanks

When data is imported from our legacy system, the same functions need to be applied to several columns on different tables. I want to build a kind of "Function Library", so that the functions I define can be re-used for columns in several packages.
The "Derived Column" transform seems ideal, if only I could add my list of user-defined functions to it. Basically I want to inherit from it, and add my own list of functions for the users to select.
Is this possible ?
What other approaches could I take to building about 30 re-usable functions?

Would anyone happen to have any pointers or know of any good code examples to either programmatically change the type of an input column when it is passed through the component, or add a new column to the output? I am extracting data from an Oracle database which is in Julian date format (represented within SSIS as a DT_NUMERIC column) and I need to to either transform the input column holding it into a date column, or to dynamically add a new output column holding the transformed data.
Many thanks

Hi,
I'm having my first go at developing a destination adapter which will send data to an update Web Service.
I've got some rather big gaps in my understanding. I've been following the various samples I've found on the net and have validated my mapping and picked up all the available column names and datatypes which are appearing in the Input and Output Properties tab of the Advanced Editor but I only have a tab for "Input Columns" and not "Column Mappings".
Which method defines the availble columns for the user to map?
Let me know if I haven't given enough information.
cheers

When replicating a table which has an identity column I get the error: "Procedure cp_insert_tblname expects parameter @C1, which was not supplied.". The stored procedure appears to be called without any parameters so my insert stored procedure does not work. I know I'm missing something basic here!! Do I have to add the field names when telling replication to use a custom stored procedure. If not, how do arguments get passed to my SP, as globals somehow?
Any info greatly appreciated!!

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've created a Custom Data Flow Component and added some Custom Properties.
I want the user to set the contents using an expression. I did some research and come up with the folowing:
Code Snippet
IDTSCustomProperty90 SourceTableProperty = ComponentMetaData.CustomPropertyCollection.New();
SourceTableProperty.ExpressionType = DTSCustomPropertyExpressionType.CPET_NOTIFY;
SourceTableProperty.Name = "SourceTable";
But it doesn't work, if I enter @[System:ackageName] in the field. It comes out "@[System:ackageName]" instead of the actual package name.
I'm also unable to find how I can tell the designer to show the Expression editor. I would like to see the elipses (...) next to my field.
Any help would be greatly appreciated!
Thank you

Hi,
I'm trying to enable Expression for a custom property in my custom data flow component.
Here is the code I wrote to declare the custom property:
public override void ProvideComponentProperties()
{
ComponentMetaData.RuntimeConnectionCollection.RemoveAll();
RemoveAllInputsOutputsAndCustomProperties();
IDTSCustomProperty90 prop = ComponentMetaData.CustomPropertyCollection.New();
prop.Name = "MyProperty";
prop.Description = "My property description";
prop.Value = string.Empty;
prop.ExpressionType = DTSCustomPropertyExpressionType.CPET_NOTIFY;
...
}
In design mode, I can assign an expression to my custom property, but it get evaluated in design mode and not in runtime
Here is my expression (a file name based on a date contained in a user variable):
"DB" + (DT_WSTR, 4)YEAR( @[User::varCurrentDate] ) + RIGHT( "0" + (DT_WSTR, 2)MONTH( @[User::varCurrentDate] ), 2 ) + "\" + (DT_WSTR, 4)YEAR( @[User::varCurrentDate] ) + RIGHT( "0" + (DT_WSTR, 2)MONTH( @[User::varCurrentDate] ), 2 ) + ".VER"
@[User::varCurrentDate] is a DateTime variable and is assign to 0 at design time
So the expression is evaluated as: "DB189912189912.VER".
My package contains 2 data flow.
At runtime,
The first one is responsible to set a valid date in @[User::varCurrentDate] variable. (the date is 2007-01-15)
The second one contains my custom data flow component with my custom property that was set to an expression at design time
When my component get executed, my custom property value is still "DB189912189912.VER" and I expected "DB200701200701.VER"
Any idea ?

All,
I am trying to achieve something as above. Basically, the Months subtotals are represented by A and B. Then (X-A) and (X-A-B) are also the subtotals at the same group level as A and B but don't simply display the total for respective years 2007 and 2008, instead those are remaning totals from X. In order to calculate the remaining totals however, one need to consider the subtotal in previous group. For example, for 2007 its X-A, but for 2008 its X-A-B. I would like to know if this can be achieved using Matrix control. If so, what would be the steps?
Thanks.

I 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.

Hi All,
I have these two commands that I execute at the end of my stored procedure. I get an email every time I execute this stored procedure whether the select statement returns a value or not. But I only want to get an email if select statement returns an Error value. How can I accomplish this?
set @cmd = 'osql -S server -U user -P psswd -q "set nocount on; select distinct(rtrim(col1)) from ##table where datediff(dd,col2,getdate()) = 1 and (col1 like ''%Error: %'')" -h-1 -w 1025 -o J:MyFolderErrorLogMsg.txt'
EXEC master.dbo.xp_cmdshell @cmd, no_output
SET @email = 'mailsend -f someone@mymail.com -d -smtp -t someone@mymail.com -sub "Error Log Errors" -m J:MyFolderErrorLogMsg.txt'
EXEC master.dbo.xp_cmdshell @email, no_output
Thanks.

I'm running asp.net 2.0 and acessing MSSQL 2K. I am trying to run a query in which I need to set up variables first. I tried the following group of commands as shown, passing it to the SqlDataReader object, but it failed.. does anyone know how i can pass multiple SQL commands? MainQuery = "declare @MinGrades as Table(GradeID Bigint) " & _ " INSERT @MinGrades SELECT MIN(CreditGrades.SplitID) AS Expr1" & _ " FROM CreditGrades INNER JOIN" & _ " CreditGradeSplits ON CreditGradeSplits.CreditGradeSplitID = CreditGrades.SplitID " & _ " WHERE (CreditGrades.x0x30 = - 1 OR " & _ " CreditGrades.x0x30 >= 0) AND (CreditGrades.x1x30 = - 1 OR " & _ " CreditGrades.x1x30 >= 0) AND (CreditGrades.x2x30 = - 1 OR " & _ " CreditGrades.x2x30 >= 0) AND (CreditGrades.x3x30 = - 1 OR " & _ " CreditGrades.x3xNOD >= 0) " & _ " GROUP BY CreditGradeSplits.CreditGradeGroupID" & _ " Select * from @MinGrades "

I am experiencing a situation where I issue a lengthy SQL command to MS SQL Server 7.0 through MTS and it "disappears" - no errors or recordsets are returned. The command is "SELECT * FROM CUSTOMERS WHERE LASTNAME LIKE 'SMITH%'". When I issue this command from SQL Query Analyzer it takes 27 seconds to return 87 rows. When I issue this exact same command through MTS it does not return at all.
I've used the SQL Profiler to analyze the requests. It shows the commands from MTS starting but they never stop (or at least the profiler never reports them as stopping). The same commands coming from Query Analyzer are reported as starting and stopping without fail.
Here's a twist: I can issue less demanding commands (ie, one that doesn't take so long to process) through MTS and they come back fine. For example, when a user logs into my application, I use an SQL statement to verify the user name and password and status the user as logged in. This is routed through MTS and it comes back fine in less than a second. Same application, same PC, same MTS and SQL server, same SQL database. The only difference is that the CUSTOMERS table has over 800,000 records and the USERS table has only 5 records.
PLEASE HELP!
