Create an Array
An array can be created in three ways.

The following code creates an Array object called myCars:

1: Regular:

var myCars=new Array(); 
myCars[0]="Saab";       
myCars[1]="Volvo";
myCars[2]="BMW";
2: Condensed:

var myCars=new Array("Saab","Volvo","BMW");
3: Literal:

var myCars=["Saab","Volvo","BMW"];

Every found that kind of error when trying to update rows in mysql? It’s because you tried to update a table without a WHERE that uses a KEY column (err …).
Anyway, The quick fix is to add SET SQL_SAFE_UPDATES=0; before your update query. Here’s the example:

SET SQL_SAFE_UPDATES=0;
DELETE FROM people WHERE person_status = 'deceased';
