DISABLE_DUPLICATE_KEY_ERROR

Disables error messaging when Vertica finds duplicate primary or unique key values at run time (for use with key constraints that are not automatically enabled). Queries execute as though no constraints are defined on the schema. Effects are session scoped.

Syntax

DISABLE_DUPLICATE_KEY_ERROR();

Privileges

Superuser

Examples

When you call DISABLE_DUPLICATE_KEY_ERROR, Vertica issues warnings letting you know that duplicate values will be ignored, and incorrect results are possible. DISABLE_DUPLICATE_KEY_ERROR is for use only for key constraints that are not automatically enabled. 

=> select DISABLE_DUPLICATE_KEY_ERROR();
WARNING 3152:  Duplicate values in columns marked as UNIQUE will now be ignored for the remainder of your session or until reenable_duplicate_key_error() is called
WARNING 3539:  Incorrect results are possible. Please contact Vertica Support if unsure
