* The {{DELETE}} statement deletes records from {{component_name}} and returns the number of records deleted.
|
||
|
|
* The optional {{WHERE}} clause specifies the conditions that identify which records to delete. Without {{WHERE}} clause, all records are deleted.
|
||
|
|
* If the {{ORDER BY}} clause is specified, the records are deleted in the order that is specified.
|
||
|
|
* The {{LIMIT}} clause places a limit on the number of rows that can be deleted. The statement will stop as soon as it has deleted {{record_count}} records.
