Last updated on AUGUST 04, 2018
Applies to:Oracle Database - Enterprise Edition - Version 22.214.171.124 and later
Oracle Database - Standard Edition - Version 126.96.36.199 and later
Oracle Database - Personal Edition - Version 188.8.131.52 and later
Information in this document applies to any platform.
- A query that had been running without error now produces an ORA-1722: invalid number error.
- The statement contains an implicit or explicit conversion from a character to a numeric type (such as during a comparison between a character type and a numeric type).
- The character column that is converted includes non-numeric data, but when the query works, such data should be filtered out using other predicates before it is checked.
This may happen after an upgrade, a change in execution plan, a change in stats, or for no apparent reason.
