Struct Statement

pub struct Statement { /* private fields */ }

A Statement is a SQL query with named parameters.

A parameter placeholder consists of ‘@’ followed by the parameter name. The parameter name is an identifier which must conform to the naming requirements in https://cloud.google.com/spanner/docs/lexical#identifiers. Parameters may appear anywhere that a literal value is expected. The same parameter name may be used more than once. It is an error to execute a statement with unbound parameters. On the other hand, it is allowable to bind parameter names that are not used.

See the documentation of the Row type for how Go types are mapped to Cloud Spanner types.

Implementations

impl Statement

pub fn new<T: Into<String>>(sql: T) -> Self

new returns a Statement with the given SQL and an empty Params map.

pub fn add_param<T>(&mut self, name: &str, value: &T)

where T: ToKind,

add_params add the bind parameter. Implement the ToKind trait to use non-predefined types.

Trait Implementations

impl Clone for Statement

fn clone(&self) -> Statement

Returns a duplicate of the value.

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

Performs copy-assignment from source.
