postgresql - SQL update in one statement instead of two -



postgresql - SQL update in one statement instead of two -

is possible next in 1 statement instead of 2. need set isactive flag 1 id , set others false. im using postgres db.

tblnames ------------------------ id,name,isactive 1,'n1',true 2,'n2',false 3,'n3',false 4,'n4',false update tblnames set isactive = true id = 4 update tblnames set isactive = false id != 4

does work?

update tblnames set isactive = (id = 4)

in case doesn't (i don't know postgres syntax enough), certainly work:

update tblnames set isactive case id when 4 true else false end

sql postgresql

string - what is the difference between "some" == "some\0" and strcmp("some","some\0") in c++? -

string - what is the difference between "some" == "some\0" and strcmp("some","some\0") in c++? - what difference between "some" == "some\0" , strcmp("some","some\0") in c++? why if("some" == "some\0") returns false , if(!strcmp("some","some\0")) returns true ? see next diagram. shows 2 strings in memory, content in box, beside box you'll see address of each one. when you're doing if("some" == "some\0") comparing addresses. translated if (0xdeadbeef == 0x0badcafe) false. when utilize strcmp , compare content of each box until reach \0 in each of them. that's why sec test returns true. if alter first test if("some" == "some") compiler may potentially see same strings , store them once. means test transform if (0x0badcafe == 0x0badcafe) true. c++ string comparison

actionscript 3 - Flex: moving a point with rotation doesnt change the point XY? -

actionscript 3 - Flex: moving a point with rotation doesnt change the point XY? - i have follow issue : i have point setted @ border on component, changed transform point center of component in order match component rotation. the of import part when seek point xy after rotation - remains same before rotation. how xy, after rotation ( changeing point.rotation property specific degrees of rotaion ) if want point after rotation, cos(r) * x, sin(r) * y easiest way. if want point after transformations, should able utilize displayobject.transform.transformpoint(x, y) . there's displayobject.localtoglobal . in case phone call localtoglobal(x, y) , localtoglobal(0, 0) , calculate difference. see transform livedocs , displayobject livedocs flex actionscript-3
