我有一个hive表包含array
和map
类型的列,我想过滤记录,其中array / map列包含多个 N 元素,怎么做那?
DDL:
create table test (id string, v1 array<int>, v2 map<string,string>)
查询:
select * from test where length(v1)>10 or length(v2)>10
答案 0 :(得分:6)
<script>
var totalItems = $('.item').length;
var currentIndex = $('div.active').index() + 1;
$('.num').html(''+currentIndex+'/'+totalItems+'');
$('.work_carousel').carousel({
interval: 2000
});
$('.work_carousel').on('slide.bs.carousel', function() {
currentIndex = $('div.active').index() + 1;
if(currentIndex >= 2){
$('#work_property').attr("id")="newid";
}
});
</script>
演示
select * from test where size(v1)>10 or size(v2)>10
create table test (id string, v1 array<int>, v2 map<string,string>);
insert into test select 1,array(1,2,3,4,5),map('K1','V1','K2','V2','K3','V3');
select size(v1),size(v2)
from test
;
