RawQuery

Struct RawQuery 

Source
pub struct RawQuery<T> { /* private fields */ }
Expand description

Typed raw SQL query that materializes rows as T.

T must implement FromRow. Raw SQL is executed exactly as written after parameter validation and optional query hint rendering; it does not apply ORM tenant or soft-delete filters automatically.

Implementations§

Source§

impl<T> RawQuery<T>
where T: FromRow + Send,

Source

pub fn param<P>(self, value: P) -> Self
where P: RawParam,

Appends one positional parameter.

Source

pub fn params<P>(self, values: P) -> Self
where P: RawParams,

Appends multiple positional parameters.

Source

pub fn query_hint(self, hint: QueryHint) -> Self

Adds a SQL Server query hint to render at the end of the raw query.

Repeated hints are deduplicated with stable ordering.

Source

pub async fn all(self) -> Result<Vec<T>, OrmError>

Executes the query and materializes all rows.

Source

pub async fn first(self) -> Result<Option<T>, OrmError>

Executes the query and materializes the first row, if any.
