implicit use of NLS session parameters may be a security risk

Cause

A conversion to a CHAR or VARCHAR type without the explicit specification of National Language Support (NLS) conversion parameters may introduce certain security risks. This often arises when the conversion happens implicitly, as when non-character types are concatenated. See the Oracle Database SQL Language Reference manual for more information about security considerations for data conversion.


Action

Rewrite implicit conversions to explicitly specify the format model to use in the conversion.
