Good Morning everyone!
I just tried to create an index on a function with no success. My syntax
seems to match the syntax shown in the docs for Create Index, but I get an
error. Any thoughts would be appreciated. Here is my attempt-
First, I did a select to make sure I had the function syntax correct, and
then tried to create the index:
staging=# select count(*) from event where
date_trunc('day',event_date_time)='07/27/2001';
count
-------
27
(1 row)
staging=#
staging=# create index event_day on
event(date_trunc('day',event_date_time));
ERROR: parser: parse error at or near "'"
Thanks!
-Nick
