Select Primary Key Column of Table returns 0 rows


I have three tables: Design, Box, Wall.

Design has a column DesignId that is a GUID. It does not allow nulls, is unique, and is the primary key. The identity is set to false for compatibility with Entity Framework v4.

Box has  a column BoxId that is a GUID. It does not allow nulls, is unique, and is the primary key. The identity is set to false as well.

Box also has a column DesignId that is a GUID. It does not allow nulls, is not unique and is not the primary key.

Wall has  a column WallId that is a GUID. It does not allow nulls, is unique, and is the primary key. The identity is set to false as well.

Wall also has a column DesignId that is a GUID. It does not allow nulls, is not unique and is not the primary key.

Wall also has a column BoxId that is a GUID. It does not allow nulls, is not unique and is not the primary key.

Box.DesignId has been set as a ForeignKey relating to Design.DesignId.

Wall.DesignId has been set as a ForeignKey relating to Design.DesignId

Wall.BoxId has been set as a ForeignKey relating to Box.BoxId.


If I execute      SELECT DesignId FROM Design     I see the correct number of rows.

If I execute     SELECT BoxId From Box        I see zer

Missing column in MSlogreader_history table in the distribution database

We recently built a new two node cluster on a Windows 2008 R2 64bit OS. We installed SQL 2005 64bit Enterprise with SP3 and CU7. We want to run replication from node 1 (1 instance - publisher) to node 2 ( 2 instances - distributor instance and a subscriber instance). We use scripts to build transactional replication (push). These scripts have been used before in an identical setup except it is CU3 instead of CU7. On our new setup, with CU7, the MSlogreader_history table in the distribution databse is missing the @updateable_row column. We only have 15 columns in this system table on our new CU7 setup. The older CU3 setup has 16 columns in the MSlogreader_history table including the updateable_row column.

Replication monitor shows an error stating that the sp_MSadd_logreader has too many arguments specified (Code 1007).

Why is our MSlogreader_history table missing the updateable_row column, and how can this be fixed?

How to select all columns except one column from a table ?



I can't figure out how to do this and hope you guys can give me a hint....

I want to select all columns from a table except one column:

For example,

A table has 20 columns : {1,2,3.....20}

To select all of columns in a table, i could use
select * from table;

However, I want to select only column {1....19}

I do not want to type the column names in one by one in the SQL query,

is there a way to achieve this in a short form of Select?


Export Visio Database Table Names to Excel

If you use the Enterprise Architect edition of Microsoft Visio for data modeling regularly, then there is a good chance that at some point you've wanted to export just the table names into Excel. You might want to do this to map logical ERD entities to physical data model tables, track project status by entity, or track overlap between database versions.

DataGrid: Tailor Your DataGrid Apps Using Table Style and Custom Column Style Objects


One of the most enduring challenges in writing user interfaces is figuring out how to display large amounts of data efficiently and intuitively without bewildering the user. The problem becomes particularly thorny when the interface must reflect hierarchical relationships within the data that the user needs to modify. The Windows Forms DataGrid control gives developers a powerful and flexible tool to meet this challenge. This article explains its basic operations and shows how to extend the DataGrid to display columns of data in an application-appropriate manner.

Do not see the table in Database after moving the project folder



I created a ASP.NET project under Visual Web Developer 2008. Under that project I had a Database (along with ASPNETDB.MDF) which has about 3/4 tables (I had SQL server 2008). Everything was working fine (like insert, delete, etc.). And I was able to view the tables in database explorer view.

Then I had to format my computer for some reason and I copied the whole project in a USB drive and then after formatting the computer I copied the folder and tried to open it in Visual Web Developer (now I have VWD 2010). I can see the both Database under App_Data folder (ASPNETDB.mdf and the DB I created). ASPNETDB has all the tables and data as expected. But I do not see the tables under the DB I created.

I also tried in one of my friends computer who has Visual Web Developer 2008. But same result.

I am just wondering if anyone can help me with retreiving the table. I have a bad feeling that I might needed to do something to backup the data (not sure though). But the tables should be still there ... isn't it ?

Any help will be appreciated. Thank you in advance.
