Обсуждение: date question

Hi everybody, in Postgres 7.0.2 I have the next query:<br /><br /> SELECT * from clientes_proceso where
fecha_mod::date<= now() -1;<br /><br /> but in version 8.0.1 returns the next error:<br /><br /> ERROR: The operator
doesn'texist: timestamp with time zone - integer<br /><br /> How can drop a day to now()??

Try using "now()::date", or "interval". Like: select * from clientes_proceso where fecha_mod::date <= now()::date -1;
or: select * from clientes_proceso where fecha_mod::date <= now() - '1
day'::interval;

You can try a couple of different things: one is to use CURRENT_DATE  
- 1 instead of now() -1. Another would be to cast now() to date,  
e.g., now()::date - 1.

Hope this helps.
