Hello friends, welcome to the new session of Oracle SQL tutorials for beginners. In today's session, we are going to see the Oracle SQL function introduction and types. Let's see the functions one by one.
In Oracle, we have two input functions. One single row function and another one multi row functions. Single row functions are further classified into five different built-in functions.
First one, character function, number function, date function, type function and general function. Each heading have some in-fold different different functions. We will see one by one in the upcoming videos.
Character functions are further classified into two types. One is CAS manipulation and character manipulation. Next we will see the types of multi row functions. Multi row functions have only one type.
that is group or aggregate functions. This group or aggregate function have some infill functions. So in the upcoming videos, we will see the functions one by one briefly with examples.
