Update yourtable set yourdatecolumn = convert (char (11), yourdatecolumn, 120! Not

In this lesson, we will learn how to use the built-in SQL System functions to complete the query job. SQL System functions are commonly used, including string functions, date functions, Aggregate functions, and data type conversion, auto-increment functions, and null functions in other function frameworks. The several functions mentioned later have been used in the previous sections. Today we will learn the
