Hello SQL!
Return a table with a single column named Greeting with the phrase 'hello world!'
Please use Data Manipulation Language and not Data Definition Language to solve this Kata
Solution:
SELECT 'hello world!' AS "Greeting"
The reason 'Greeting' is enclosed in double quotation marks is that uppercase letters are changed to lowercase letters unless they are enclosed in double quotation marks.
Result:
Greeting |
hello world! |
