Statement attributes are characteristics of the statement. For example, whether to use bookmarks and what kind of cursor to use with the statement’s result set are statement attributes.

Statement attributes are set with SQLSetStmtAttr and their current settings retrieved with SQLGetStmtAttr. There is no requirement that an application set any statement attributes; all statement attributes have defaults, some of which are driver-specific. When a statement attribute can be set depends on the attribute itself. The Concurrency, CursorType, SimulateCursor, and UseBookmarsstatement attributes must be set before the statement is executed. TheAsyncEnableandNoScanstatement attributes can be set at any time but are not applied until the statement is used again.MaxLength, MaxRows, and QueryTimeout` statement attributes can be set at any time, but it is driver-specific whether they are applied before the statement is used again. The remaining statement attributes can be set at any time.

Trait Implementations

impl Clone for StatementAttribute

fn clone(&self) -> StatementAttribute

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for StatementAttribute

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

Formats the value using the given formatter.

impl PartialEq<StatementAttribute> for StatementAttribute

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

This method tests for self and other values to be equal, and is used by ==.

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

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