zhaowang updated CALCITE-7079:
------------------------------
Description:
Mongodb adapter translate more than one $ne condition error.
run sql:
{code:java}
select city, state from zips where city <> 'ABERDEEN' and city <> 'AIKEN'{code}
query plan:
{code:java}
{
"$match": {
"city": {
"$ne": "AIKEN"
}
}
}, {$project: {CITY: '$city', STATE: '$state'}}{code}
The condition (city <> 'ABERDEEN') lost，actually, more than one $ne condition
conpose of AND have to translate to $nin operation, such as:
{code:java}
{
"$match": {
"city": {
"$nin": [
"AIKEN",
"ABERDEEN"
]
}
}
}, {$project: {CITY: '$city', STATE: '$state'}} {code}
More test case:
Case 1:
{code:java}
select city, state from zips where city <> 'ABERDEEN' and city <> 'AIKEN' and
state <> 'a' and state <> 'b' {code}
Query plan:
{code:java}
{
"$match": {
"city": {
"$nin": [
"ABERDEEN",
"AIKEN"
]
},
"state": {
"$nin": [
"a",
"b"
]
}
}
}, {$project: {CITY: '$city', STATE: '$state'}} {code}
Case 2:
{code:java}
select city, state from zips where city <> 'ABERDEEN' and city <> 'AIKEN' and
state <> 'a' and state <> 'b' {code}
