SQL Command DELETE

 
The DELETE command has the following specification:
 
DELETE [*]
FROM TableName
[WHERE logical_expression]
 
where:
* - used for compatibility purpose. A delete statement applies to an entire row, so there is no need to identify the fields in the table.
 
TableName – specify the name of the table for which the command is applied.
 
logical_expression – identifies those rows that must be deleted from the table.
When no logical expression is provided, all the rows from the table will be deleted.
However, the table itself will still remain in the database, and it will have the same structure.
In order to delete the table, use the FTP DELE command on the table file.
 
Examples
delete * from cards
delete from cards
delete * from cards where id=1
delete * from cards where id=1 OR id=2
