function returns a given string an expression or values in a column in all uppercase letters upper string it accepts input as a string and returns text in uppercase letters special case if characters in the input are not of type string they remain unaffected by the upper function unicode is supported for the upper function examples basic upper function this basic query converts the given string to all uppercase letters select upper postgresql the query returns upper postgresql upper function using columns and concat function this example shows how the upper function works with columns a table named personal_details contains employee s id first_name last_name and gender of a retail store create table personal_details id int first_name text last_name text gender text insert into personal_details id first_name last_name gender values 1 mark wheeler m 2 tom hanks m 3 jane hopper f 4 emily byers f 5 lucas sinclair m select from personal_details the query returns id first_name last_name gender 1 mark wheeler m 2 tom hanks m 3 jane hopper f 4 emily byers f 5 lucas sinclair m assume that the goal is to convert employees first and last names with id numbers 1 3 and 5 to all uppercase letters then combine them using the concat function into one full_name column in uppercase use this query select concat upper first_name upper last_name as full_name from personal_details where id in 1 3 5 the output displays the first and last names of employees with the specified ids in uppercase letters full_name mark wheeler jane hopper lucas sinclair back to top simple online
