Use of Rank() function in SQL (SQL Server,Oracle)


SELECT Rank() OVER (ORDER BY receiptdate ) as Firt_Arrival,locationnumber,receiptdate FROM inventorylocsubdetail


Here Rank() fn would return the rank based on the ReceiptDate. But this would be jumbling if there are same rank more than one.


E.g: here rank 4 repeating for three records,because of this the next rank is 7 (4,4,4,7)

Use of Begin, Commit, Rollback Transactions in SQL Server

Image
The SQL Server provides very useful feature which is Begin, Commit, Rollback Transaction. When we use Begin Transaction before we use DML Queries, we can Commit or Rollback that Transaction after the confirmation. This is very useful if you update anything wrongly then you can rollback that transaction. For example,As shown below, I am trying to update the NodeID column data to 5 from 1. begin transaction update DownLoad_Data set NodeID=5 But after I updated, You can check whether you have been updated properly.

If it is updated correctly then, Run the Commit Transaction to make all updates permanently. Commit...

SQL SERVER – TRIM() Function – UDF TRIM()

SQL Server does not have Trim() function. So we can create a own UDF (User Defined Function) function for this since SQL Sever does LTRIM(),RTRIM() functions and we can use this any time. Here I have created a simple Function for this. Create Function Trim(@mText varchar(MAX)) Returns varchar(MAX) AS Begin return LTRIM(RTRIM(@mText)) End You can run this function as shown below here, Select dbo.Trim(' Test ') So this function would return ‘Test’ only as LTRIM() function would cut off the Left side spaces and RTRIM() functiom would cut off the Right side spaces.
