Hi,
I have two columns OLD and NEW in a table.
for few rows I have either blanks values in OLD column, but in NEW there are values.
my function takes values from OLD as parameter and converts them into values (that are in NEW column).
it works for all values of OLD column except ''(blanks), which have corresponding values in NEW column.
when I pass ' '(blank), the function gives follo. error
============
ORA-20163: function did not find value for ' '
=====
but actually, there is a value exists for ' ' in table.
I wonder why its giving that error.
Thanks

Hi,
I think u can make use of chr(32) , where value 32 is for blank & to check for presence of blank in a column, u can use instr like below example
SQL> select empno,stars,instr(stars,chr(32)) from empp
the above query will give u the location of blank.
Based on the result u can take decision
Bye
