pub struct SqlQuery { /* private fields */ }
Expand description

The return value of sql_query.

Unlike most queries in Diesel, SqlQuery loads its data by column name, rather than by index. This means that you cannot deserialize this query into a tuple, and any structs used must implement QueryableByName.

See sql_query for examples.

Implementations

Bind a value for use with this SQL query.

Safety

This function should be used with care, as Diesel cannot validate that the value is of the right type nor can it validate that you have passed the correct number of parameters.

Example
let users = sql_query("SELECT * FROM users WHERE id > ? AND name <> ?")
    .bind::<Integer, _>(1)
    .bind::<Text, _>("Tess")
    .get_results(&connection);
let expected_users = vec![
    User { id: 3, name: "Jim".into() },
];
assert_eq!(Ok(expected_users), users);
