[SQL] Dynamic Query for System functions - now()

[Kumar]

Dear Friends,   I am using PostgreSQL 7.3.4 Server on RH Linux 7.2. I am trying to generate a dynamic query to fetch the next month interval.   select now()+ interval'1 month';  -- This is working fine.   I wanna dynamically assign the interval number. i,e --> select now()+ interval'n month';   For this I wanted to write a dynamic query. EXECUTE 'select now()+ interval\'' || 3|| 'month\''; Error     ERROR:  parser: parse error at or near "'select now()+ interval\''" at character 9   Help help me with this. I wanted to use this query inside a PLpgSQL function.   Regards Kumar
