The column is a Varchar named prize. They have to become: 85. Oracle provides conversion functions that will easily convert values of one datatype to another. While Oracle will perform implicit conversions of datatypes for you, this can lead to performance problems in your applications and to compatibility problems in future versions of Oracle. Consider a table T that has columns, of type VARCHAR2.

TO_NUMBER halts conversion when it encounters a nonnumeric character (such as a letter or a numeric group separator). When i try to compare high_value (long data Type) and number. This looks a lot like Oracle , but I suspect that the result would be similar in any SQL that used to_number.
