MySQL DELETE

To delete data from a table, you use the MySQL DELETE statement. The following illustrates the syntax of the DELETE statement:

DELETE FROM table_name
WHERE condition;
In this statement:

First, specify the table from which you delete data.
Second, use a condition to specify which rows to delete in the WHERE clause. The DELETE statement will delete rows that match the condition,

mySql delete

DELETE FROM somelog WHERE user = 'jcole'
ORDER BY timestamp_column LIMIT 1;

delete record mysql

DELETE FROM table_name [WHERE Clause]
	1. If the WHERE clause is not specified, then all the records will be deleted from the given MySQL table.
	2. You can specify any condition using the WHERE clause.
	3. You can delete records in a single table at a time.
The WHERE clause is very useful when you want to delete selected rows in a table.
