Trying to Remove Leading and Trailing Spaces using Trim but its not Working

Question

I've tried

update Table_Name set Name=Trim(Name)

But its not working..the string in which i want to remove leading and trailing spaces is as follows:

'  % of critical assets, that should be monitored via PdM technologies, are being monitored '

which is currently in the column named as Name from my table

Answer 1

If the datatype is CHAR or NCHAR, you cannot remove trailing spaces. You can only do that on VARCHAR/NVARCHAR

Answer 2

Try using

update Table_Name set Name=LTRIM(RTRIM(Name)) 

instead of TRIM
