Execute the following T-SQL scripts in Microsoft SQL Server Manangement Studio Query Editor to demonstrate T-SQL convert and cast functions in transforming string date, string time & string datetime data to datetime data type. Other datetime manipulation examples are presented as well.

– Microsoft SQL Server string to date conversion – datetime string format sql server

– MSSQL string to datetime conversion – convert char to date sql server

– Subtract 100 from style number (format) for yy instead yyyy (or ccyy with century)
