SELECT id,x,y FROM `chars开发者_如何学编程` WHERE `mapa`='1'
how can i exclude row when id='3'
SELECT id,x,y FROM `chars` WHERE `mapa`='1' and id <> '3'
What is the data type of id
though? If numeric you would want to use
SELECT id,x,y FROM `chars` WHERE `mapa`='1' and id <> 3
In MySQL you can also use !=
rather than <>
but <>
is ANSI and more portable.
SELECT id,x,y FROM `chars` WHERE `mapa`='1' AND `id`<>3
