Description: Returns the result of converting number n from base base1 to base base2.
base1 and base2 should be integers between 2 and 36. x is treated as a BIGINT but may be specified as a string (which may be required for bases above base-10, in which characters A through Z, or equally a through z, may be used).
Returns a string result. Returns a NULL if any argument is NULL. Returns 0 if n is not legal in base1.
Examples:
CONV(1001,2,10) returns 9.
CONV('FF',16,10) returns 255.
CONV('abc',16,10) returns 2748.
CONV(16,10,8) returns 20.
CONV('abc',16,10) returns 2748.
CONV(10101010,2,16) returns AA.
