A Simple Introduction to Dynamic SQL

Dynamic SQL is essentially normal SQL written in such a way that you end up with a “customised” SQL script at run-time.

Dynamic SQL and TempTables

Execute Dynamic SQL commands in SQL Server

In some applications having hard coded SQL statements is not appealing, because of the dynamic nature of the queries being issued against the database server. Because of this sometimes there is a need to dynamically create a SQL statement on the fly and then run that command. This can be done quite simply from the application perspective where the statement is built on the fly whether you are using ASP.NET, ColdFusion or any other programming language. But how do you do this from within a SQL Server stored procedure?

Dynamic Pivot, Passing Temp Table Variables to Dynamic SQL

This example demonstrates how to perform a pivot using dynamic headers based on the row values of a table. The article also shows how to pass a temp table variable to a Dynamic SQL call.

Alter all/specific columns by double dynamic SQL

The script uses dynamic SQL twice
first to get the detail about the database structure and create ddl out of it
second to execute each DDL created

Dynamic Table Name on Select Into

Based upon todays date as suffix and chosen string as prefix, select data from predefined table into dynamically named new table. Script is properly error handled with most common errors
