Introduction
Syntax of PL/pgSQL
Function parameters
Instruction
Awesome! Another way to invoke a function with OUT parameters is to treat it like a table (because OUT parameters essentialy generate columns):
SELECT * FROM get_count_of_employees(2);
The output is basically represetned as columns – one for each OUT parameter. Each of the columns has the name of the related OUT parameter. The first column is assigned the value 0; the second column is assigned the value 10.
Exercise
Run the template query.
