Read all keys and values from resource file

I have added Resource1.resx file in my project. This reosurce file contains some key - value entries.

Scenario : Suppose you have localized country list and you have stored localized country list in resource file for performance reason. You can store localized list in sql table but if you want to avoid database hit and read it on server side.

This function reads Resource1.resx file and reads all keys of that resource file.

 public static List<string> GetAllResourceKeyStrings()
            List<string> resourceKeyStrings = new List<string>();
             ResourceSet resourceSet = null;
            resourceSet = Resource1.ResourceManager.GetResourceSet(CultureInfo.CurrentCulture, true, true);
            IDictionaryEnumerator Myenumerator = resourceSet.GetEnumerator();
            while (Myenumerator.MoveNext())
            return resourceKeyStrings;

Reseeding/reset the identity of table.

Generally, on inserting the new data into table we get next seed value for identity column. When a row is deleted, we cannot use that identity value again. We can resolve it by reseeding the identity of table as follows:

1. SELECT * FROM Sample_Data

2. DELETE FROM Sample_Data WHERE Number > 4

SELECT @MaxID=MAX(Number) FROM Sample_Data


Checking identity information: current identity value '16'.
DBCC execution completed. If DBCC printed error messages, contact your system administrator.
4. INSERT INTO Sample_Data(Value) VALUES('Second')

ELSE qs.statement_end_offset
END - qs.statement_start_offset)/2)+1),

Sql Azure : Way Around for Sp_depends in Sql Azure

You can use following query to find out table used in Stored procedures similar to sp_depends.

SELECT ReferencingObjectType = o1.type,
       ReferencingObject = SCHEMA_NAME(o1.schema_id)+'.',
       ReferencedObject = SCHEMA_NAME(o2.schema_id)+'.'+ed.referenced_entity_name,
       ReferencedObjectType = o2.type
FROM   sys.sql_expression_dependencies ed
       INNER JOIN  sys.objects o1
         ON ed.referencing_id = o1.object_id
       INNER JOIN sys.objects o2
         ON ed.referenced_id = o2.object_id
WHERE o1.type in ('P','TR','V', 'TF') and ed.referenced_entity_name like '<Table Name>'
ORDER BY ReferencingObjectType, ReferencingObject

replace <Table name>  with your actual table name which you want to search

Steps to Create a customize Role for Azure database

Steps to Create a customize Role for Azure database
Download "Azure User Management Console" tool from

Create a Login
Use “Azure User Management Console”
EG: dbdevwebuser
Create User for login on master
Connect to master database, and execute the following:
CREATE USER dbdevwebuser FOR LOGIN dbdevwebuser WITH DEFAULT_SCHEMA=[dbo]

This has created user “dbdevwebuser” for the login “dbdevwebuser”.
Note: You can keep the login and the user name separate.

Create User for login on the database to be used by application
Connect to application database, and execute the following:
CREATE USER dbdevwebuser FOR LOGIN dbdevwebuser WITH DEFAULT_SCHEMA=[dbo]

Create Customized Role 
Connect to application database, and execute the following:
This will create a role by the name “db_executor”

Grant Permissions to Customized Role 
Here I am trying to create a role to grant execute for all stored procedure
GRANT EXECUTE TO [db_executor]

This will grant execute permission to the role “db_executor”
Note: You can “GRANT” more permission to this role, to make it more customized.

Assign Roles to User Created
Assign different roles of your choice to the user
sp_addrolemember @rolename = 'db_executor', @membername = 'dbdevwebuser'
sp_addrolemember @rolename = 'db_datareader', @membername = 'dbdevwebuser'
sp_addrolemember @rolename = 'db_datawriter', @membername = 'dbdevwebuser'

This will assign roles of “db_executor”, “db_datawrited” and “db_datareader” to the user 'dbdevwebuser' on the application database.
1. These kind of roles are usually used when you want your application to execute procedures, read and write data. But do not want them to manipulate any Schema.

Testing working of the User for the Roles Assigned

This user should
1. Execute procedure
2. Select, Insert, Update, Delete from the database
3. Create Temporary tables
4. Select View
This user should not:
1. Create, ALTER, Delete Table
2. Create, ALTER, Delete Procedure
3. Create, ALTER, Delete View
4. Create, ALTER, Delete Function
5. See Content “sp_helptext” for a Procedure

How to make a database copy from production to staging server in Azure

On the same server

1.       Connect to destination server (Here Staging DB) “master” database with productions username and pwd  because we need to have same username with pwd on source and destination DB.

2.       Execute the following command:
b.      IMP: Replace the NEWDATABASENAME, SOURCE_SERVERNAME and SOURCEDATASE with correct names
To track progress you can run following command or you can connect to Azure portal and check the progress in database tab

3.       Execute: Select *  from sys.dm_database_copies, this will give you the stats of the % of database copied
