ERROR: One or more rows violate unique constraint on ...

Reason:

You attempted to insert rows in a table using insert_rows() but the rows being inserted violate a unique constraint on the table. That is, the insert would cause one or more rows in the table to contain duplicate values in the columns of a unique constraint.

Resolution:

You cannot insert rows that violate a unique constraint.

Tips:

• The error message identifies the columns in the unique constraint.
