ERROR: Distribution constraint already exists on table ...

Reason:

You attempted to create a distribution constraint using create_distribution_constraint() on a table but that table already has a distribution constraint

Resolution:

Ensure the table does not already have a distribution constraint

Tips:

• Is the table name correct?
• Does the table need to be qualified by a schema?
• Use the star$tables view to find the name and scope of known tables
• Use the star$constraints view to find the names of tables with distribution constraints
