Script To Grab Column Names As UML Properties

-

I was cooking up some UML diagrams for an existing DB and wanted to get all of the properties. It lists the table, column name in UML markup format and then the data type. The data type column is there so that all I have to do is order it by the second column and I’ll get all of the nulls so I can see if I’m getting a data type that I haven’t handled. The data type conversion is by no means complete but it’s a good start.

Enjoy!

select table_name, '+ ' + column_name + ' : ' +
    CASE WHEN DATA_TYPE in ('ntext', 'nvarchar', 'varchar', 'char') then 'string'
        WHEN DATA_TYPE = 'bit' then 'bool'
        WHEN DATA_TYPE = 'int' then 'int'
        WHEN DATA_TYPE = 'timestamp' then 'timestamp'
        WHEN DATA_TYPE = 'uniqueidentifier' then 'Guid'
        WHEN DATA_TYPE = 'money' then 'decimal'
        WHEN DATA_TYPE in ('smalldatetime', 'datetime') then 'datetime'
        END,
    DATA_TYPE
from INFORMATION_SCHEMA.COLUMNS
where TABLE_NAME not like '%aspnet%'
    and TABLE_NAME <> 'sysdiagrams'
order by 1, 2

Migrating Legacy Apps to the New SimpleMembership Provider

-

Asp.Net MVC4 uses the new SimpleMembership provider, changes the table structure and adds a new hashing algorithm. The reasons for the changes can be found in this article by Jon Galloway. This article shows how to migrate your existing apps to the new provider. I’m assuming that you stored your passwords in the unrecoverable SHA-1 format. If you didn’t, then you’ll have to change a couple of things. All of my apps are done this way so… I’m also assuming that you have created the basic skeleton of the new app and ran it once so the correct tables will be created. First, we’ll look at the new tables. Previously, we had all of those aspnet_xxxxxx tables. Here’s the new ones. UserProfile Contains all of the elements relevant to the user. This is a combination of the aspnet_Users table and the aspnet_Profiles table. webpages_Membership Stores the password info when not using OAuth, Live, Facebook, etc. This table is somewhat of a match to the aspnet_Membership table. webpage...

Get Asp.Net Profile properties from Sql

-

Ever wanted to include the profile information from an Asp.Net profile in a query? It’s not that hard once you understand the structure. I’ve written a little function that does all the work. Note: I’m using Sql Server as my repository. First we need to understand how the profile data is stored. Looking at the aspnet_Profile table, we can see that it stores the information in two columns: PropertyNames and PropertyValuesString. Looking at PropertyNames we can see that it has a basic structure of Property Name, Data Type, Starting Position and Length. For example, in the string “FirstName:S:0:4:Phone:S:4:10:LastName:S:14:5:” we can see that FirstName is of type string, starts at position 0 and has a length of 4. Notice the zero base for the starting position, we need to correct for that in our function. This means in the PropertyValuesString “John2175551212Smith”, we would start with the first position and proceed 4 c...
