Enum QueryResultKind 

pub enum QueryResultKind {
    Rows,
    Mutation,
    Deletion,
    Ddl,
    Train,
    Admin,
}

Classifies the kind of VelesQL statement that was executed.

Variants

Rows

Row-returning query (SELECT, MATCH, SHOW, DESCRIBE).

Mutation

Data manipulation that returns affected rows (INSERT, UPSERT, UPDATE).

Deletion

Deletion that returns affected count.

Ddl

DDL statement (CREATE, DROP, ALTER, TRUNCATE).

Train

TRAIN QUANTIZER.

Admin

Admin command (FLUSH, ANALYZE).
