Drop a Column in SQL

EasySQL · PostgreSQL

Problem

How do you drop a column from a table (DDL)? Asked in the first-round screen stage.

Output

  1. Provide the PostgreSQL DDL statement that removes the specified column from the table.
  2. The statement should target the column named in the prompt and leave the rest of the table unchanged.
  3. If the column is referenced by dependent objects, note that the operation may require additional handling before it succeeds.
