QuerySql

Struct QuerySql 

Source
pub struct QuerySql {
    pub stmt: Statement,
    pub ret: Option<Vec<Type>>,
    pub last_insert_id_hack: Option<u64>,
}
Expand description

Executes a SQL statement against the database.

Only sent to SQL-capable drivers (those with Capability::sql set to true). The statement is a fully lowered stmt::Statement that the SQL serialization layer converts into a backend-specific SQL string.

§Examples

use toasty_core::driver::operation::{QuerySql, Operation};

let op = QuerySql {
    stmt: sql_statement,
    ret: Some(vec![stmt::Type::String, stmt::Type::I64]),
    last_insert_id_hack: None,
};
let operation: Operation = op.into();
assert!(operation.is_query_sql());

Fields§

§stmt: Statement

The SQL statement to execute.

§ret: Option<Vec<Type>>

The types of columns in the result set. When Some, the driver uses these types to decode returned rows. When None, the statement does not return rows (e.g., DELETE without RETURNING).

§last_insert_id_hack: Option<u64>

Temporary MySQL workaround for RETURNING from INSERT.

When set, the driver should fetch LAST_INSERT_ID() to simulate RETURNING behavior for the specified number of inserted rows. Non-MySQL drivers should assert this is None.
