Accessing `_score` from SQL looks like:
```
--------------------------------------------------
POST /_sql
{
"query": "SELECT SCORE(), * FROM library WHERE match(name, 'dune') ORDER BY SCORE() DESC"
}
--------------------------------------------------
```
This replaces elastic/x-pack-elasticsearch#3187
relates elastic/x-pack-elasticsearch#2887

[[sql-translate]]

|
== SQL Translate API
|
|
|
|
The SQL Translate API accepts SQL in a JSON document and translates it
|
|
into native Elasticsearch queries. For example:
|
|
|
|
[source,js]
|
|
--------------------------------------------------
|
|
POST /_xpack/sql/translate
|
|
{
|
|
"query": "SELECT * FROM library ORDER BY page_count DESC",
|
|
"fetch_size": 10
|
|
}
|
|
--------------------------------------------------
|
|
// CONSOLE
|
|
// TEST[setup:library]
|
|
|
|
Which returns:
|
|
|
|
[source,js]
|
|
--------------------------------------------------
|
|
{
|
|
"size" : 10,
|
|
"docvalue_fields" : [
|
|
"page_count",
|
|
"release_date"
|
|
],
|
|
"_source": {
|
|
"includes": [
|
|
"author",
|
|
"name"
|
|
],
|
|
"excludes": []
|
|
},
|
|
"sort" : [
|
|
{
|
|
"page_count" : {
|
|
"order" : "desc"
|
|
}
|
|
}
|
|
]
|
|
}
|
|
--------------------------------------------------
|
|
// TESTRESPONSE
|
|
|
|
Which is the request that SQL will run to provide the results.
|
|
In this case, SQL will use the <<search-request-scroll,scroll>>
|
|
API. If the result contained an aggregation then SQL would use
|
|
the normal <<search-request-body,search>> API.
|
|
|
|
The request body accepts all of the <<sql-rest-fields,fields>> that
|
|
the <<sql-rest,SQL REST API>> accepts except `cursor`.
