The problem isn't with 10g, it is with your NLS parameters and/or the data. The error comes from the values in the column not from your 88. The 88 converts fine to a number, but the values in your column do not. Any non-numeric values in the column will cause this.

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?
