Question

I have a column A in a table called T. The column is of type nvarchar(255).

There is a trigger on this table that updates the values in column A to a column B in table B. The column B is of type float.

Suppose if there is value 35.1 % in column A, I want to strip off the % and update only 35.1 in column B. It is not necessary that there should be a % symbol for the value in column A.

How do I do this in SQL Server 2008? Any ideas and suggestions are much appreciated!

You may try to use the following query:

update B
set B.colB = cast(REPLACE(A.colA, '%', '') as float)
from A
where B.idB = A.idA
