Fields

columns: Vec<ColumnMetadata>

rows: Vec<Vec<Option<QueryValue>>>

out_values: Vec<(usize, Option<QueryValue>)>

return_values: Vec<(usize, Vec<Option<QueryValue>>)>

cursor_id: u32

row_count: u64

more_rows: bool

compilation_error_warning: bool

last_rowid: Option<String>

Encoded rowid of the last affected row (reference cursor lastrowid).

batch_errors: Vec<BatchServerError>

Batch errors collected with executemany(batcherrors=True).

array_dml_row_counts: Option<Vec<u64>>

Per-iteration row counts from executemany(arraydmlrowcounts=True).

implicit_resultsets: Option<Vec<QueryValue>>

Child cursors returned via dbms_sql.return_result (QueryValue::Cursor entries); Some only when the response carried a TNS_MSG_TYPE_IMPLICIT_RESULTSET message.

token_num: Option<u64>

Pipeline token echoed by the server (TNS message 33) at the start of each pipelined response; None outside pipelines.

sessionless_txn_state: Option<SessionlessTxnState>

Sessionless transaction state update carried by the response’s SYNC server-side piggyback (reference _update_sessionless_txn_state); None when the execute did not change the sessionless state.

query_id: Option<u64>

CQN registered-query id read from the registration-info block of the execute return parameters (reference cursor_impl._query_id, base.pyx:1300-1309). Some(0) when the server returned no query id (qos without SUBSCR_QOS_QUERY); None when the block was absent.

txn_in_progress: Option<bool>

Whether a server-side transaction is in progress, sampled from the final end-of-call status bit TNS_EOCS_FLAGS_TXN_IN_PROGRESS (reference protocol.pyx _process_call_status). None when the response carried no STATUS message (the caller then leaves the flag unchanged).

Implementations

impl QueryResult

pub fn cell(&self, row: usize, col: usize) -> Option<&QueryValue>

Borrow the value at (row, col) of the fetched result, or None when either index is out of range or the cell is SQL NULL. Convenience accessor so callers do not have to index rows[row][col] and unwrap the Option by hand.

pub fn column_index(&self, name: &str) -> Option<usize>

Zero-based column index of the column whose name matches name case-insensitively (Oracle folds unquoted identifiers to upper case), or None when there is no such column.

Trait Implementations

impl Clone for QueryResult

fn clone(&self) -> QueryResult

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for QueryResult

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for QueryResult

fn default() -> QueryResult

Returns the “default value” for a type.

impl PartialEq for QueryResult

fn eq(&self, other: &QueryResult) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
