Subject Re: jsp 2.0 el string functions error
Date Mon, 21 Jun 2004 14:31:51 GMT
Thank you for your reply. I found out that fn:length function can't be used 
to get the length of an integer object from sql query. So instead I changed 
my query to get the length of the variable and passed that to my 
fn:substring function. It appears that fn:length can only be done on 
strings but SELECT LENGTH() can be used both for integer and string functions
