array. Detach the I/O operation of the tempdb database to speed performance. The tempdb database should have the appropriate capacity to meet the needs of the user. Space for the tempdb database should be allowed to grow automatically. If set to not allow automatic growth, the operation cannot be completed when the query operation establishes a temporary table that exceeds the capacity of the tempdb database. Appropriately set the growth of the tempdb database, too small growth will result in
