== SQL Translate API
The SQL Translate API accepts SQL in a JSON document and translates it
into native {es} queries. For example:
[source,console]
--------------------------------------------------
POST /_sql/translate
{
"query": "SELECT * FROM library ORDER BY page_count DESC",
"fetch_size": 10
}
--------------------------------------------------
// TEST[setup:library]
Which returns:
[source,console-result]
--------------------------------------------------
{
"size": 10,
"docvalue_fields": [
{
"field": "release_date",
"format": "epoch_millis"
}
],
"_source": {
"includes": [
"author",
"name",
"page_count"
],
"excludes": []
},
"sort": [
{
"page_count": {
"order": "desc",
"missing": "_first",
"unmapped_type": "short"
}
}
]
}
--------------------------------------------------
Which is the request that SQL will run to provide the results.
In this case, SQL will use the <<scroll-search-results,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`.
