alexduta updated NIFI-14162:
----------------------------
Description:
It seems that, in Nifi, in the QueryRecord processor, if you define some
columns you select from flowfile, it is following the order, but is taking the
values in their order from the original flowfile.
As an example:
Original Json flowfile:
{code:java}
// [{
"ArticleCode" : "12345",
"ProductCode" : "10101",
"ArticleName" : "Credit Card",
"ProductName" : "Porduct Credit",
"Country" : "RO"
}] {code}
Query:
{code:java}
// select ArticleCode,ArticleName,ProductCode,ProductName,Country from FLOWFILE
{code}
Returning file:
{code:java}
// [{
"ArticleCode" : "12345",
"ArticleName" : "10101",
"ProductCode" : "Credit Card",
"ProductName" : "Porduct Credit",
"Country" : "RO"
}] {code}
So, it is somehow just adding the name of the columns, but is not changing the
values.
Otherwise, if one of the records in the flowfile has the correct order in it,
the others will follow the correct rule:
Original file:
{code:java}
// [{
"ArticleCode" : "12345",
"ArticleName" : "Credit Card",
"ProductCode" : "10101",
"ProductName" : "Porduct Credit",
"Country" : "RO"
},
{
"ArticleCode" : "12346",
"ProductCode" : "10102",
"ArticleName" : "Business Card",
"ProductName" : "Society Credit",
"Country" : "RO"
}] {code}
or
{code:java}
// [
{
"ArticleCode" : "12345",
"ProductCode" : "10101",
"ArticleName" : "Credit Card",
"ProductName" : "Porduct Credit",
"Country" : "RO"
},{
"ArticleCode" : "12346",
"ArticleName" : "Business Card",
"ProductCode" : "10102",
"ProductName" : "Society Credit",
"Country" : "RO"
}] {code}
Returning file:

"ArticleCode" : "12345",
"ArticleName" : "Credit Card",
"ProductCode" : "10101",
"ProductName" : "Porduct Credit",
"Country" : "RO"
},
{
"ArticleCode" : "12346",
"ArticleName" : "Business Card",
"ProductCode" : "10102",
"ProductName" : "Society Credit",
"Country" : "RO"
}] {code}
