Hi masters,
I'm thinking in putting some staging tables on tempdb.
This are empty tables that receive some data from a bulk insert and then i make same validations to this data and insert it on my real tables on my user databases.
I have some question about tempdb, maybe you can help me.
1) TempDB is all reconstructed every time the server (SQL Server) Starts, correct?
2) If the answer to the first question, is yes, this means that the stating tables that i have created the last time on tempdb , now (that the server restarted) are lost and i have to create them again. Correct?
Do you know if you lose perfomance when inserting (from a bulk_insert) data to a staging table on a tempdb Vs on a staging table in a user db?
tks,
Pedro

Humm.. I am not so sure but may be it depends on your disk configuration? not sure though

this is supposing you have the files of tempdb on the same disc conditions as the user databases.

Don't. TempDB is for temp tables and other temporary objects. Either create a staging database and put your tables in there or put them in the same database as the final tables are in.

I'm with Gail, don't put staging tables in there.
Create another filegroup on a new disk, or a new database to hold staging data. Tempdb is for temp working space that SQL needs, not you.
