Deletes

The query builder may also be used to delete records from the table via the delete method. You may constrain delete statements by adding where clauses before calling the delete method:

//qb
var deleteRecords = query.from( "users" )
    .whereID( 10 )
    .delete();
writeDump(deleteRecords);

//sql
DELETE FROM `users` WHERE `ID` = 10;

This utilizes the where clause on a column other than the ID:

//qb
var deleteRecords = query.from( "users" )
    .where( 'age', '>', 50 )
    .delete();
writeDump(deleteRecords);

//sql
DELETE FROM `users` WHERE `age` > 50
