SQL Server parse and compile time: CPU time = 0 ms, elapsed time = 17 ms. Scan count 1, logical reads 23751, physical reads 0, read-ahead reads 0, lob logical reads 0, lob physical reads 0, lob read-ahead reads 0.
In this step we are doing an UPDATE to the table and for each row that is updated we are updating the variable by 1 as well as the id column in the table.
The first approach that may come to mind is to add an identity column to your table if the table does not already have an identity column.
We will take a look at this approach as well as looking at how to do this with a simple UPDATE statement.
These guidelines are designed to be compatible with Joe Celko’s SQL Programming Style book to make adoption for teams who have already read that book easier.
This guide is a little more opinionated in some areas and in others a little more relaxed.Starting with SQL Server 2016, you can create the table as a clustered columnstore index.It is no longer necessary to first create a rowstore table and then convert it to a clustered columnstore index. ] table_name [ WITH ( DROP_EXISTING = ) ] --default is OFF [;] CREATE CLUSTERED COLUMNSTORE INDEXCreate a clustered columnstore index in which all of the data is compressed and stored by column.Our task is to protect this data by encrypting the column, which contains the credit card number.I will populate it will some sample data as shown below.This can be seen here (SET @id = id = @id 1) where we are making the @id value and the id column equal to the current @id value 1.
