ERROR: Column ... does not exist in table ...

Reason:

You attempted to drop a foreign key constraint using create_foreign_constraint() on a table but specified a column that does not exist in the table.

Resolution:

Ensure you specify a known column in the table.

Tips:

• Was the column name spelled correctly?
• Use the star$columns view to find the columns in the table.
• Use the star$constraints view to find the columns in foreign key constraints.
