Lets say we have a string = 'A1B2C3D4'. Our objective is to replace A with 1, B
with 2, C with 3 and D with 4 to derive 11223344 string.
Using existing REPLACE method
REPLACE(REPLACE(REPLACE(REPLACE('ABCD','A','1'),'B','2'),'C','3'),'D','4')
With proposed UDF : REPLACE_MULTI method
General Syntax :
REPLACE_MULTI( sourceString, [ search1#replacement1, ... ] )
REPLACE_MULTI('abcd',['A'#'1','B'#'2', 'C'#'3', 'D'#'4'])
Advantage :
1. Function calls are reduced.
2. Ease to code and better readable.
Let me know your thoughts/ inputs on having this UDF in Piggy Bank. Will take
this up based on this.
