Ubuntu on BIOS RAID (fake RAID)

Submitted by st on

I seem that "fake RAID" term is not really corresponding to actual motherboard design. Indeed, I don't see the differences between Marvell RAID controller implanted into my motherboard and my old Silicon Image PCI SATA 4-port card.

However, Ubuntu 14.04 cannot be installed "by default" in both cases. Follow these step-by-step instructions.

Fast inserting a file into a table

Submitted by st on

How to insert fast a file (i.e. binary one) from disk to a SQL Server table?

Certainly the SQL Server account should have a corresponding permissions to access the file on the disk. For example I take the file C:\WINDOWS\system32\oembios.bin having the size about 12 MB. For really big files you'd better switch to the FILESTREAM approach.

SQL: generate date/time series

Submitted by st on

There are many examples of user defined table functions generating the series of dates(times) between two specified values. Usually, in OLAP you can see a table filled by the date/time series, too. Such table avoid to generate the values "on the fly".

However, in some cases you may be unable to use an UDF or a table. Fortunately, "pure SQL" method still works.

Suppose, the start and finish dates are specified as entry parameters. The transact SQL code below generates the series "moth by month".
