[piplive]

explain select sum(money) as allMoney from person where id=3
result is
{
"size" : 0,
"timeout" : 10000,
"query" : {
"term" : {
"id" : 3
}
},
"aggregations" : {
"filter" : {
"filter" : {
"term" : {
"id" : 3
}
},
"aggregations" : {
"sum(Money)" : {
"sum" : {
"field" : "Money"
}
}
}
}
}
}
the 'money' become 'Money'

I suggest you modify the 251 1ine on Heading.java or SelectParser.java about 'createColumn'
