Hi all:
I want to do a daily rotated insertion according the data's date field. The data come from a real time analyzer, which
meansit's date field is nearly the current date but not exactly, even not exactly in the date order.
The real trouble is it will be a heavy insertion, I don't want to code a complex trigger function. I'd like to simply
redirectthe insertion to a "CURRENT" table, and rename it every mid-night. But it's difficult to make 'check', which is
requiredby a better query performance.
Well, I can create a trigger to redirect insertion to 'yesterday', 'today' and 'tomorrow', but I am still expecting a
moresimple and more fast solution.
Any idea is appreciated. Thanks in advance.
Best regards.
