PostgreSQL - Removing Temporary Table Last Updated : 28 Aug, 2020 Comments Improve Suggest changes Like Article Like Report In PostgreSQL, one can drop a temporary table by the use of the DROP TABLE statement. Syntax: DROP TABLE temp_table_name; Unlike the CREATE TABLE statement, the DROP TABLE statement does not have the TEMP or TEMPORARY keyword created specifically for temporary tables. To demonstrate the process of dropping a temporary table let's first create one by following the below instructions. First, we create a sample database(say, test) to add a temporary table using the below statement: CREATE DATABASE test; After creating the database we switch into it using the following command: \c test; Now we add a temporary table (say, mytemp) to the test database as below: CREATE TABLE mytemp(c INT); Verify if the table has been created using the below statement: SELECT * FROM mytemp; It should show you the below table: Now that our temporary table is created we remove it in the below example. Example: We use the DROP TABLE statement inside the database test as follows to drop the temporary table: DROP TABLE mytemp; Now we verify if the table has been removed successfully using the below statement: SELECT * FROM mytemp; Output: The above-shown error raised by PostgreSQL shows that the mytemp table doesn't exist anymore.
