Emulate the Initcap functionSQL

In many database systems, there is a SQL function called something like INITCAP which capitalizes the first letter of all the words in a text string. Unfortunately, DuckDB doesn’t have this built-in, so let’s see if we can emulate it using function chaining and list comprehension.

Execute this SQL

SELECT ([upper (x[1])||x[2:] 
for x in 
(
'the quick brown fox jumped over the lazy dog'
).string_split(' ')]).list_aggr('string_agg',' ') 
Copy code
