Hello all, Any one could suggest the best way to copy data from table to table in the same db, the reason why am seeking for this is that the first table is becoming very big, and old data has no reason why to stay there, so i created a cloned table but without indexes and constraints (lighter) and now i would like to copy 'some' data from first to second table (copied data is data older than 3 months, i have a timestamp column).
In other way, i have a table called 'hotqueues' where i store fresh messages queued, once messages are treated, they stay in 'hotqueues' but with a flag indicating that their arent queued for treatment.. so in this way, data will rest there forever, slowing down any searches in that table, the solution was to copy old messages to another table called 'coldqueues' that has the same structure as 'hotqueues' but lighter (without constraints and indexes). How to copy these data with 100% data-loose free.
