mysql - will limit work same for both condition in select and delete statement -
i have pick unused items table, move items other info used table called useditems
. while items moved have delete items unused table.
so have write downwards next query .
insert used select knumber unused limit 1000; delete unused limit 1000;
my concern point pick same record not using order in query , in table have single column . inserted records deleted.
i new mysql .
instead utilize order by
clause limit
clause create sure same picking of records , limit out order won't create much sense cause limit may end inserting/deleting different set off info whereas goal delete same set of info inserting.
insert used select knumber unused order knumber limit 1000; delete unused order knumber limit 1000;
mysql sql
