PostgreSQL Create Table: Create a table countries, including columns which already exist
2. Write a SQL statement to create a simple table countries, including columns country_id,country_name and region_id which already exist.
CREATE TABLE countries ( COUNTRY_ID varchar(3), COUNTRY_NAME varchar(45) , REGION_ID decimal(10,0) );
Here is the output for the above SQL statement. The following output shows an error message, because the table already exists.
postgres=# CREATE TABLE countries ( postgres(# COUNTRY_ID varchar(3), postgres(# COUNTRY_NAME varchar(45), postgres(# REGION_ID decimal(10,0) postgres(# ); ERROR: relation "countries" already exists
