my database shows a status2 value of 1090519040. But in http://msdn.microsoft.com/en-us/library/aa260406%28SQL.80%29.aspx i do not see such a value- how do you interpret it then?

thanks

No.  That is the combination of two different bit values being set:

1073741824
16777216

Unfortunately, BOL doesn't document the meanings of those two particular bits.

In SQL an integer is signed, and is 4 bytes, thus 31 bits.

Each bit can be on or off, of course, and has its own unique value.  Off is always 0.  On is by power of two, like so:
Bit0 = 1; Bit1 = 2; Bit3 = 4; Bit4 = 8; etc.

So, say bits 1 and 4 were on ... the field would contain 10 ( 2 + 8 ) .

Note that no bits ever overlap, even when added up.  That is, the sum of all preceding bits is always one less than the current bit.  (For example, Bit5 = 16; the sum of all earlier bits being on is 15).

Thus, you can always tell which individual bits are on and which are on in a given total value for the integer.

Add them:

1073741824 + 16777216 = 1090519040

That means no other bits are on, or the value would be higher.  Each bit on increases the value of the integer column.

OK. Many thanks Scott.

But, on the first hand, how did you quickly discern the 2 numbers.
16777216 is also not in that reference.

do you know these numbers just by experience?

and 1073741824 is in status column. So that means these values float between status and status2?

Nah.  I just kept using power of 2 values, then did a quick test to see if they were present :-) .
