Hi,
I have a little problem with extract epoch from interval. It seems that the
query works if the interval is in a string but not from DB field.
Could someone provide support.
(...)
You have a casting error; instead of:
dbr=# SELECT extract(EPOCH FROM INTERVAL b) FROM a;
ERROR: syntax error at or near "b"
LINE 1: SELECT extract(EPOCH FROM INTERVAL b) FROM a;
use
SELECT extract(EPOCH FROM b::INTERVAL) FROM a;
or
SELECT extract(EPOCH FROM CAST (b AS INTERVAL)) FROM a;
