Sometimes rather than updating, we wish to get rid of records from the table. To do so, we can use the DELETE FROM command. The syntax for this is
DELETE FROM "table_name"
WHERE {condition}
It is easiest to use an example. Say we currently have a table as below:
Table Store_Information
store_name Sales Date
Los Angeles $1500 Jan-05-1999
San Diego $250 Jan-07-1999
Los Angeles $300 Jan-08-1999
Boston $700 Jan-08-1999
and we decide not to keep any information on Los Angeles in this table. We type the following SQL:
DELETE FROM Store_Information
WHERE store_name = "Los Angeles"
The resulting table would look like
Table Store_Information
store_name Sales Date
San Diego $250 Jan-07-1999
Boston $700 Jan-08-1999
