Index on a staging table
948012Jul 9 2012 — edited Jul 9 2012I have 2 similar tables. Same columns. Data inserted to second table from first for a condition and first table is truncated. Then data moved from second to first and second table truncated. Second table is to store data for a small period of time. First table has indexes. Do I need any index on second table?
The query on second table is always insert into second select * from first. Similarly insert into first select * from second.
