Please, help me!
My code:
"IF char_length(substring(str from '^[a-zA-Z]*://'))=0 THEN
str:= 'http://'||str;
END IF;"
If str= http://www.msn.com then nothing happen
(all is OK), but if str= just www.msn.com then nothing happen too!
Why?
Then I experimen with that:
I change '=' to '<>'
results:
str=http://www.msn.com -> http://http://www.msn.com
str=www.msn.com -> http://www.msn.com
Thank you.
