Expand description

Optional execute modes (reference ExecuteMessage attributes).

Fields§

§batcherrors: bool§arraydmlrowcounts: bool§parse_only: bool

Parse/describe without executing (reference parse_only).

§token_num: u64

Pipeline token; pipelined operations carry tokens 1..N (impl/thin/connection.pyx _create_messages_for_pipeline), everything else carries 0.

§cursor_id: u32

Server cursor id of an already-parsed statement; non-zero skips the PARSE option and SQL text (reference Statement._cursor_id).

§cache_statement: bool

Whether the statement may be kept in the connection statement cache (reference cursor.prepare(cache_statement=...)).

§scrollable: bool

Whether the cursor was opened scrollable; sets the scrollable execute flags and primes the fetch orientation (reference cursor_impl.scrollable).

§fetch_orientation: u32

Fetch orientation for the next fetch (reference fetch_orientation, al8i4[10]); one of the TNS_FETCH_ORIENTATION_* constants. Zero leaves the server default.

§fetch_pos: u32

Desired row position paired with fetch_orientation (reference fetch_pos, al8i4[11]).

§scroll_operation: bool

True when this execute is a scroll request: the EXECUTE/BIND options are suppressed so the server only repositions the open cursor and fetches (reference scroll_operation).

§suspend_on_success: bool

Suspend the active sessionless transaction once this execute succeeds (reference cursor_impl.suspend_on_success); the driver folds a post-detach into the sessionless piggyback. Does not affect the execute wire body itself.

§no_prefetch: bool

Suppress the FETCH execute option so the server does not prefetch any rows during the execute round trip (reference stmt._no_prefetch, execute.pyx:99). Set when re-executing an open cursor whose columns require a client-side define (VECTOR): a prefetched row would otherwise exhaust the cursor before the define-fetch runs, yielding ORA-01002 on the subsequent fetch.

§registration_id: u64

CQN registration id threaded into the execute body (split into lsb/msb at the al8i4 slots) when registering a query against a subscription (reference cursor_impl._registration_id, execute.pyx:116-163). Zero for ordinary executes.
