Best match query

Hi Forum,

I have the following table, around 60k records .. table name is "destinations"

Code:

BG,United Kingdom Mobile,004474572,0.20441,O 
BG,United Kingdom Mobile,004479,0.20441,O 
BG,United Kingdom Mobile,004479932,0.2222,O 
BG,United Kingdom Mobile,00447993,0.20,O 
BG,United Kingdom Mobile,004477,0.20441,O 
BG,United Kingdom Mobile,00447620,0.20441,O 
BG,United Kingdom Mobile,0044758,0.20441,O 
BG,United Kingdom Mobile,004475897,0.20441,O 
. 
. 
.

select * from destinations where prefix like '0044799326542%' will not get any results since 0044799326542 does not exist,

what Im trying to achieve is,

if 0044799326542 is not found, try 004479932654,
select * from destinations where prefix like '004479932654%' -- no match

if no match, try 00447993265
select * from destinations where prefix like '00447993265%' -- no match

if no match, try 0044799326
select * from destinations where prefix like '0044799326%' -- no match

if no match, try 004479932
select * from destinations where prefix like '004479932%' -- match
BG,United Kingdom Mobile,004479932,0.2222,O

how to achieve this without having to go through all iterations ?

Thanks
