If you really do mean decimal (base 10) you could use Gordon's solution
like this:
SELECT
MID(CONV(HEX(245),16,2),1,1) AS `7`,
MID(CONV(HEX(245),16,2),2,1) AS `6`,
MID(CONV(HEX(245),16,2),3,1) AS `5`,
MID(CONV(HEX(245),16,2),4,1) AS `4`,
MID(CONV(HEX(245),16,2),5,1) AS `3`,
MID(CONV(HEX(245),16,2),6,1) AS `2`,
MID(CONV(HEX(245),16,2),7,1) AS `1`,
MID(CONV(HEX(245),16,2),8,1) AS `0` ;
Results:
+---+---+---+---+---+---+---+---+
| 7 | 6 | 5 | 4 | 3 | 2 | 1 | 0 |
+---+---+---+---+---+---+---+---+
| 1 | 1 | 1 | 1 | 0 | 1 | 0 | 1 |
+---+---+---+---+---+---+---+---+
Hope this helps.

If by Decimal you mesn HEXIDECIMAL you can use CONV
where the 1st arg is the HEX value,
2nd arg is From Base
and 3rd arg is To Base.
You will have to suround the aliases with "`'s" if you really want
the names to be numeric.
mysql> select MID(CONV('A5',16,2),1,1) AS `7`,
-> MID(CONV('A5',16,2),2,1) AS `6`,

Subject: Converting decimal to binary
Can anyone tell me if it's possible, in 4.1.11, to convert a decimal
number to binary and have the result be returned as a separate field for
each bit? For example, what I'd like to do is,
Select ConvertToBin(245);
And have a result that looked like this
+---+---+---+---+---+---+---+---+
| 7 | 6 | 5 | 4 | 3 | 2 | 1 | 0 |
+---+---+---+---+---+---+---+---+
| 1 | 1 | 1 | 1 | 0 | 1 | 0 | 1 |
+---+---+---+---+---+---+---+---+
- Thanks
