MS SQL Server: Search All Tables, Columns & Rows For Data or Keyword Query

If you need to search your entire database for specific data, this query will come in handy.

So when a client needs a custom report or some sort of custom development using Great Plains, most of the time I will have to track down the data in the system by running this query and find the table(s) it is in.

Entity Data Model and database view returning the same columns as there are in a table


When adding a stored procedure into the Entity Data Model I can select whether the procedure returns a scalar, a (new) complex type or one of the entity types I already defined. 

How do I do something similar for a view?

I mean assuming I have a view like this

CREATE VIEW FilteredFoos as SELECT Foo.* FROM Foo join ... WHERE ...

(that is a view that implements some involved filtering, but returns all columns from one table) how do I add it to the project so that I can use the entity set, but get the Foo objects, not some new FilteredFoo objects.

var foos = myDB.FilteredFoos.Include("Bar").ToList();

foreach (Foo foo in foos) { ...

Thanks, Jenda

How to create scrolling table for columns in a SharePoint Designer Data View


I have a fairly complex SharePoint Designer 2007 Data View they have added two more requirements.

1. Have the columns on the right side be able to scroll left to right as there is a large number of columns, while the first 3 columns on the left side stay locked in place.  This is only one list not two, and because of some other requirements I have it must remain to be just one list.

2. Then they also need to have scrolling up and down of the entire list with the headers locked in place.

The first requirement is more important than the second, but preferrably I need to do both.

I am new to XSL so not familar with the syntax. Is this something I can do on a custom Data View? Does anyone have any examples of how?

I have a drawing that show how it needs to look but I don't see an option here to upload a graphic.

So here is a link to my graphic example uploaded to my blog area: http://lindachapman.blogspot.com/  or just the image here: http://4.bp.blogspot.com/_aB01ue__NvQ/TGL42MOvrGI/AAAAAAAAAA4/c3xP4uCy4BU/s1600/Scrolling.png

Library - Fill Columns with data from email

I have an inbound email enabled Library.  The Library has several columns created for it.  I would like to be able to send an email into the Library and have these columns filled from information in the email.  Is this possible using WSS 3.0?  What are the basic steps?  If I understand SharePoint well enough, I'm guessing is that I have to include the columns as Metadata in the body of the email and then assign this Metadata to the appropriate Library columns when new email is uploaded to the Library.

Transposing data into columns

Hello All Consider the follwing dataset/layout: Person ID Question Answer P1 Q1 Q1 Answer P1 Q2 Q2 Answer P1 Q3 Q3 Answer P2 Q1 Q1 Answer P2 Q2 Q2 Answer P2 Q3 Q3 Answer I'd like to be able to have a list of 'Persons' with their associated questions and answers like this: Person ID Q1 Q2 Q3 P1 Q1 Answer Q2 Answer Q3 Answer P2 Q1 Answer Q2 Answer Q3 Answer (The questions will remain the same for each person, but will have different answers). There will be other fields in there too (such as a date and various other bits of demographics) but if I can nail the methodology, I can expand it to include. I've done this kind of thing in the past, but can never reproduce the code/methodology off the top of my head! Any tips would be great... Cheers Leeroyster

INSERT statement with OUTPUT clause, referencing outer query columns

I have a problem to solve and I have run into what appears to be a limitation of TSQL.  I have looked around and did not find much on this subject, so I apologize if this duplicates another post.  I am using SQL Server 2008. From what I have read on BOL, when you are performing a DELETE or UPDATE statement, you can reference unaffected columns from the outer query in the OUTPUT clause, but this is apparently not allowed in an INSERT statement. I am working on a process that will create new copies of existing records - essentially, the user can create a whole new copy of a set of records, and the process requires that I track both what the original PK values were and the corresponding PK values for the new rows. This example will hopefully spell out my problem.  This script shows two tables, [Primary_Object] and [Secondary_Object].  Not shown here are multiple tables that rely on [Secondary_Table], which is why I have to be able to track this info. This first script shows the setup of the tables involved and the data involved: /* create test data */ create table primary_object ( primary_object_id int identity(1,1), parent_object_id int, name char(1)) create table secondary_object ( secondary_object_id int identity, primary_object_id int, amount money) insert into primary_object (parent_object_id, name) select 0, 'A' insert into secon

Unable to prepare the SSIS bulk insert for data insertion

Hi,   I am using SQL Server Destinations in my data flow tasks. I'm running this package in the server until i encountered this error:   OnError,,,LOAD AND UPDATE Dimension Tables,,,10/24/2007 1:22:23 PM,10/24/2007 1:22:23 PM,-1071636367,0x,Unable to prepare the SSIS bulk insert for data insertion.

SQL ServerDestination error - Unable to prepare the SSIS bulk insert for data insertion.

Having searched the forum, this one clearly has form... However beyond assisting those who have fallen at the first hurdle (i.e. forgetting/not knowing that they cannot execute the package remotely to the instance of SQL Server into which they are inserting), the issues raised by others have not been addressed. Thus I am bringing nothing new to the table here - just providing an executive summary of problems which others have run into, written about, but not received answers for.   First the complete error: Description: Unable to prepare the SSIS bulk insert for data insertion.  End Error  Error: 2008-01-15 04:55:27.58     Code: 0xC004701A     Source: <xxx> DTS.Pipeline     Description: component "<xxx> failed the pre-execute phase and returned error code 0xC0202071.  End Error  DTExec: The package execution returned DTSER_FAILURE (1).  Started:  4:53:34 AM  Finished: 5:00:00 AM  Elapsed:  385.384 seconds.  The package execution failed.  The step failed.   Important points It mostly works - It produces no error more than 9 times out of 10. It fails on random dataflows - My package has several dataflows, (mostly) executing concurrently. Where the error occurs it does not do so on the same dataflow each time: on one run it'll fail on dataflow A whilst B,C,D and E succeed, then A-E will all succeed (and continue doing so for the next ten runs thereafter), and


the database result is as follows DATE     code   class1 class2  class3 1/8/10     M1     10       20     30     3/8/10     V2      20       30     10      1/8/10      H1      1           2      3         7/8/10     ! ! 8/8/10     !M2    5      5      5       3/8/10     B2      4      4     4       1/8/10     V1      3      7     3       THE OUTPUT SHOULD BE AS FOLLOWS:- DATE           M1                          M2           

Comparing columns with NULL values--Merge says unmatched when data is matched.

I found the article below describing this same issue with the Oracle merge statement.  It also described a work-around:    http://searchoracle.techtarget.com/tip/Merging-datasets-with-NULL-values I have been unable to find a solution to this issue for SQL Server 2008.  I am trying to do basic ETL from Staging table to a Type II dimension table in a Data Warehouse.  I am using the Merge statement with the Unique key minus the modification date as my merge key list.  I have a handful of columns (in both Staging and the DW) containing nulls in my merge key list.  I have tried the ISNULL function and the ANSI_NULL db option (OFF) with no success.  When I put zeros in the null columns, it works as expected.  I am about to try separate INSERT and UPDATE statements, but I fear that the NULL comparison issue will bite me there with the JOIN statement.  Has anyone else experienced this?  NULL values are valid in our Data Warehouse.  How can I make T-SQL handle them? Thank you for your help, Jesse

OLEDB/ADO Destionation - Add input column twice to destination columns or static data


(Using BIDS 2008 R2)

OLEDB/ADO Destionation

Reuse input column
Is there any way to map a input column to two destination columns?

State static value instead of mapping column
I have a package for each version of the production system - they insert in the same destination tables - I just need to add a version number to the version column - like '2.1' and '3.0'. The only way I have found so far is to select a fake column in the source like select '2.2' as Version, ..- This is however not very smart when I'm selecting millions of rows.

I would just like to be able to type in a static value instead of mapping a column - any way to do this?

vertical headers aligned to bottom in WPF Data Grid(.Net 4)


Hello. I need vertical headers in my Datagrid.

I'm using this template:

<DataTemplate x:Key="RotateHeaderTemplate" > 

 <TextBlock Text="{Binding}" >


 <RotateTransform Angle="-90" />




Then i'm adding columns like this:

new DataGridTextColumn
Header = "header",
HeaderTemplate = (DataTemplate)Resourses["RotateHeaderTemplate"],
Binding = new Binding("mark")

And then i get smth like this: http://img265.imageshack.us/img265/7585/headers1.png

But i need headers aligned to bottom. Like here http://img695.imageshack.us/img695/2765/headers2.png

How can i do it?

How can I avoid entering Output columns manually (with their data types) in the Script Transformatio

I created a wrapper to a WCF web service that is returning many datasets with hundreds of columns.  The destination database schema matches the source schema exactly.  When i make the connection on a ADO.NET destination object to my database it auto-generates my list of columns.  I understand that the script component could output anything so it can't autogenerate at this point, but is there any way to copy and paste the Column definitions from somwhere else and paste them in?  I'd like to avoid spending hours entering all these manually.
