PostgreSQL – How to Drop A Column

ByAdmin

To drop a column in PostgreSQL, you can use the ALTER TABLE statement with the DROP COLUMN clause. Here’s the basic syntax for dropping a column:

ALTER TABLE table_name DROP COLUMN column_name;

where table_name is the name of the table from which you want to drop the column, and column_name is the name of the column you want to remove.

Please note that dropping a column is a data-altering operation, and it will permanently remove the column and its data from the table. Make sure to back up your data before executing this operation, especially in a production environment.
