Hello everyone,

Can anyone please help me with a problem I'm having difficulty figuring out. I have a field named [FINAL_RATE] which is a float with values including 0, 0.34, 0.038, etc.

I would like to move the decimal over to the right in all cases possible whether there is 0, 1, 2, 3, etc. decimal places.

Thank you for the help.

try:-
UPDATE Table
SET FINAL_RATE=FINAL_RATE * POWER(10,LEN(LEFT(REVERSE(CAST(FINAL_RATE as varchar(10))),CHARINDEX('.',REVERSE(CAST(FINAL_RATE as varchar(10))))-1)))

change it like this & try:-
UPDATE Table
SET FINAL_RATE=FINAL_RATE * POWER(10,LEN(LEFT(REVERSE(CAST(FINAL_RATE as varchar(10))),CASE WHEN CHARINDEX('.',REVERSE(CAST(FINAL_RATE as varchar(10))))>0 THEN CHARINDEX('.',REVERSE(CAST(FINAL_RATE as varchar(10)))) ELSE 1 END -1)))

I am not sure if this works

Select replace(FINAL_RATE,'.','') as FINAL_RATE from yourtable
