CONV

Description

Do radix conversion for input parameter.

Syntax

CONV(<input>, <from_base>, <to_base>)

Parameters

Parameter	Description
<input>	Parameters to be converted, either as strings or integers
<from_base>	Numeric, the source base, within [2,36].
<to_base>	Numeric, the target base, within [2,36].

Return Value

The number under the converted target binary <to_base> is returned as a string. When any input parameter is NULL, returns NULL. If <from_base> or <to_base> does not meet the range requirement, returns NULL.
