Create Temporary virtual table (or a records set) with SQL Server Stored Procedure

Some time we need to create a virtual table to manipulate data without affecting the actual data in the actual table. You can create a virtual table by two ways. Using CREATE TABLE statement and with DECLARE statement.

Let’s consider, I have student table(tblStudent) contain sName, sAddress, ClassId and class table(tblClass) contain classId and ClassName. Now I want to SELECT Name, Address and ClassName based on string pattern and Stored it to a virtual table.

First of all take a look at our table structure…

Table 1 – tblStudent
SrNo sName sAddress ClassId
1 Lucy Redmond 1

3 Mitchell Mumbai 1
4 Scott SmallVilla 2
5 Kathryn Redmond 3
6 Frank Mumbai 1
