Response

The Response class wraps the results returned by a SurrealQL query execution. A single query string can contain multiple statements, and the Response holds the result of each statement indexed by its zero-based position.

Source: surrealdb.java

Methods

`.take(index)`

Extracts the result of a specific statement from the response by its zero-based index. The untyped variant returns a raw Value, while the typed variant deserializes the result into the specified Java class.

Method Syntax

Value take(int num)
<T> List<T> take(Class<T> type, int num)

Parameter	Type	Description
`type`	`Class<T>`	The class to deserialize the result into. Omit for an untyped `Value` return.
`num`	`int`	The zero-based index of the statement result to extract.

Returns: Value (untyped) or List<T> (typed)

Example

Response response = db.query("SELECT * FROM users; SELECT * FROM posts;");

Value users = response.take(0);
List<Post> posts = response.take(Post.class, 1);

`.size()`

Returns the number of statement results contained in the response.

Method Syntax

response.size()

Returns: int

Example

Response response = db.query("SELECT * FROM users; SELECT * FROM posts;");
int count = response.size();

Working with multi-statement responses

import com.surrealdb.Surreal;
import com.surrealdb.Response;
import com.surrealdb.signin.RootCredential;

try (Surreal db = new Surreal()) {
    db.connect("ws://localhost:8000");
    db.useNs("surrealdb").useDb("docs");
    db.signin(new RootCredential("root", "root"));

    Response response = db.query(
        "CREATE person SET name = 'Alice'; SELECT * FROM person;"
    );

    int statementCount = response.size();

    Value created = response.take(0);
    List<Person> people = response.take(Person.class, 1);
}
