David,
Did you review the data in the field from the two databases? Maybe the
9i database has all number values while the 10g database has some char
values?

Subject: data type conversion in 10g
We have Oracle 10.2.0.3. There is one field, test1 that is definite as
char(2). When we use 'where test1<88', it works fine in 9i, but we get
'ORA-01722 invalid number' error in 10g. Once I add single quotes
around 88, the error is gone. I know the best practice is not to use
implicit conversion. Just wonder why it works in 9i, but not in 10g,
more restriction in 10g or if there is any change in 10g that causes the
error tracked?
