Finding table data partition bounds key values using SQL

Posted By:      Posted Date: September 16, 2010    Points: 0   Category :Sql Server
I have a table that has few million rows and I need the front end application to partition all the data for this table, or any other large table, using sql where clauses so I can retrieve all the data for the table in different threads for each "partition" in parallel (I can't/do not need to know whether the table data is actually partitioned on any specific column at the server). Assume that each "partition" can have n rows (dynamically), is there an easy way of find out what are the bounds for such partitions in terms of the table PK/unique index? Example, create table table_test (col1 char(8) primary key); Example table data: col1 (PK) a b c d e f g   The bounds for table_test for partitions of 2 rows would be four partitions that have the following values for col1: c, e, g  and the font end app would be able to use these bound to generate sql such as: select * from test_table where col1 < 'c'; -- first partition select * from test_table where col1 >= 'c' and col1 < 'e'; -- second partition select * from test_table where col1 >= 'e' and col1 < 'g'; -- third partition select * from test_table where col1 >= 'g'; -- fourth partition So the question is whether the values 'c', 'e', 'g' bounds of the table data can be easily determined by using sql by the client font end.        Farid Zidan Zi

Checkboxes from data table

How to deal with NULL values in a SQL table


 Hi all

In order to add/update/delete data from a table I build 2 classes: 1 class containing all the table fields and another class with methods to add/insert/update/delete records. I am learning how to avoid errors when your table must use SQL NULL values. One error is when I call my UPDATE method (see below):

  public void UpdateItem(OcItemConstraintDetails item)
  SqlConnection con = new SqlConnection(connectionString);
  SqlCommand cmd = new SqlCommand("ItemConstraints_Update", con);
  cmd.CommandType = CommandType.StoredProcedure;

  cmd.Parameters.Add(new SqlParameter("@itemConstraintId", SqlDbType.Int, 4));
  cmd.Parameters["@itemConstraintId"].Value = item.ItemConstraintId;

  cmd.Parameters.Add(new SqlParameter("@path", SqlDbType.NVarChar, 150));
  cmd.Parameters["@path"].Value = item.Path;

if you watch the SQL profiler trace you will see that I am passing a value of 'default' ;so that causes me problems.

exec ItemConstraints_Update @itemConstraintId=1,@path=default

With that said, what are the best practices when your SQL table accepts NULL values and when:
- you are passing an empty value to your stored procedure;

need your help regarding table and database.. without data lose

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

Model Binding the values in an HTML Table back to Controller / Model


Currently, I am working with ASP.NET MVC1 and am still learning about Model Binding and how values from a View are passed back to the Controller / Model. Specifically, I want take an existing Model, create a Table and populate the Rows of the Table, allow the user to edit some fields and pass it back.

In my example, I have a Class called "Ingredient" which has 4 public accessors:  Name, Barcode, Amount, and Unit

<%@ Page Title="" Language="C#" MasterPageFile="~/Views/Shared/Site.Master" Inherits="System.Web.Mvc.ViewPage<IEnumerable<MvcACE.DomainModel.Entities.Ingredient>>" %>

<% using (Html.BeginForm("SubmitOrder","MyController"))
{ %>

<% if (Model != null)
foreach (var item in Model)
{ %>
<td><%= Html.Encode(item.Name)%></td>
<td><%= Html.Encode(item.Barcode)%></

How do you create a custom BDC data field that allows for multiple selected values?
