Struct QuerySql 

pub struct QuerySql {
    pub stmt: Statement,
    pub params: Vec<TypedValue>,
    pub ret: Option<Vec<Type>>,
}

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,
    params: vec![],
    ret: Some(vec![stmt::Type::String, stmt::Type::I64]),
};
let operation: Operation = op.into();
assert!(operation.is_query_sql());

Fields

stmt: Statement

The SQL statement to execute. Scalar values that should be sent as bind parameters have been replaced with Expr::Arg(n) where n is the index into params.

params: Vec<TypedValue>

Typed bind parameters extracted from the statement. Each entry corresponds to an Expr::Arg(n) placeholder in the statement.

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).
