Struct NativeQuery 

pub struct NativeQuery {
    pub name: String,
    pub kind: NativeQueryKind,
    pub tables: Vec<String>,
    pub columns: Vec<NativeQueryColumn>,
    pub criteria: Vec<String>,
    pub group_by: Vec<String>,
    pub having: Vec<String>,
    pub joins: Vec<NativeJoin>,
    pub order_by: Vec<NativeOrder>,
    pub select_flags: i64,
    pub parameters: Vec<String>,
}

One native saved query as stored in the Jet/ACE file (M3, read-only).

Fields

name: String

Query name from MSysObjects.

kind: NativeQueryKind

Query flavor from the object flags.

tables: Vec<String>

FROM tables in attribute order.

columns: Vec<NativeQueryColumn>

Selected columns.

criteria: Vec<String>

WHERE expressions verbatim (attribute 8).

group_by: Vec<String>

GROUP BY expressions verbatim (attribute 9) — a documented rest for execution (step 27.1, M12).

having: Vec<String>

HAVING expressions verbatim (attribute 10) — a documented rest.

joins: Vec<NativeJoin>

JOIN expressions with their flavors (attribute 7).

order_by: Vec<NativeOrder>

ORDER BY entries (attribute 11).

select_flags: i64

Select-type bits of attribute 1 (0x01 star, 0x02 distinct, 0x08 distinct row, 0x10 top, 0x20 percent).

parameters: Vec<String>

Parameter names (attribute 2) — parameters stay a documented rest.

Implementations

impl NativeQuery

pub fn query_def(&self) -> Option<QueryDef>

Maps the decodable subset onto a QBE query definition: select queries over exactly one table, plain field columns, no criteria, grouping, joins or computed columns. This is the read-only design grid’s projection only; execution goes through crate::native_exec (step 27.1, M12).

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

Performs copy-assignment from source.

impl Debug for NativeQuery

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for NativeQuery

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,
