Serial number or row number



Sometimes there would be a requirement to add serial number (or) row number to the result set.

Example: The requirement would be to select some columns from the database tables along with Serial Number like below

SNo
Customer_Name
Customer_Phone_Number
1
aaa
xxx-xxx-xxxx
2
bbb
xxx-xxx-xxxx

So, in this post we will see how we can select that using T-SQL on Microsoft SQL Server 2008

We can achieve this in several ways:

1) Using Row_Number()
 

Row_Number() Returns the sequential number of a row within a partition of a result set, starting at 1 for the first row in each partition. 

T-SQL Script:

        SELECT ROW_NUMBER() OVER (ORDER BY CUSTOMER_ID) AS [S.No]
                        ,CUSTOMER_NAME
                        ,CUSTOMER_PHONE_NUMBER
        FROM database.dbo.tblTableName


2) Using Identity(Property)
 

Identity() property creates an identity column in the table. So, first we need to create a temporary table with [S.No] column on it and then we will select the required columns from the temporary table.

T-SQL Script:
 
        SELECT IDENTITY(INT,1,1) AS [S.No]
                       ,CUSTOMER_NAME
                       ,CUSTOMER_PHONE_NUMBER
        INTO #tempTable
        FROM database.dbo.tblTableName


        --Now, the result set 


        
SELECT [S.No]
                       ,CUSTOMER_NAME
                       ,CUSTOMER_PHONE_NUMBER
        FROM #tempTable

mongoDB error : aborting after fassert() failure

What to do when facing errors on mongoDB “aborting after fassert() failure”

I like errors, in mongoDB this is the first error I faced and luckily many times. This error i faced during restoring name-space on local and restarting db system. I am still searching the exact root cause of this issue but i am able to resolve the current problem through below steps.

Remove all relevant namespace files from data-file route path..Now repair mongo instance using mongod process.mongod --repair ////////// execute command from bin folder path Then start server using mongd process, if started server successfully then ..mongod  ////////// execute command from bin folder path Restore last backups as normal process.Now check database by connecting mongo shell. Thanks for reading, 
Please comment your experience if you faced and also share knowledge if you have better steps to resolve...

Last week I got this error from one of developer who was trying to deploy his project from Testing server to SQL Azure QA server. He was using “Deploy Database to SQL Azure” option from SSMS Tool-Task option.

Validation of the schema model for data package failed. Error SQL71562: Error validating element xx.xxx.xx:function .dbo.xxx has an unresolved refrence to object xx.dbo.xxxx external refrences are not supported when creating a package from this platform.

DACFx must block Export when object definitions (views, procedures, etc.) contain external references, as Azure SQL Database does not allow cross-database external references So, this error was coming.

Solution : I suggested him to create those function to locally on local database what…
