| Didn't this turn up yesterday? Can't find itIt's defined starting with # for a temp table, ## for a global temp.They are held in tempdb (with a long extension which holds a sequence number and reference to the spid) and only accessible by that spid.Temp tables are dropped when the batch that created them ends - that is usually a stored procedure or connection (spid).If a temp table is created on a spid then a subordinate batch creates it again another copy of the temp table will be crated with the same name - held with a different sequence number in tempdb. The temp table with the latest sequence number is always the one referenced.A temp table can be referenced in a batch if it is created in a calling batch (e.g. an SP can use a temp table created before it runs)Global temp tables are similar but can be accessed by any spid once they are created.==========================================Cursors are useful if you don't know sql.SSIS can be used in a similar way.Beer is not cold and it isn't fizzy. |
