I know this question could be so basic. I am just supposed to Update a column that looks like
with just the 5 numeric digits found at the end. some of the Data in the column has Space inbetween the STRING. I want to truncate the space and update it with somthing like substr(stringname,3,5) ... So what do i do to truncate Space in the data. I tried (trim(chr(32) from string_name and it did not return the desired results.
To get the last 5 characters of stringname:
To get the group of digits at the end of the string, regardless of how many there are:
SUBSTR ( stringname , -5 )
Whenever you have a problem, it helps if you post a little sample data (CREATE TABLE and INSERT statments) and the results you want from that data.
REGEXP_SUBSTR ( stringname , '[0-9]+$' )
If you know it's always the last 5 characters of the string you could use:
If you want to remove spaces you can use:
