[−][src]Struct diesel::expression::UncheckedBind
Returned by the SqlLiteral::bind()
method when binding a value to a fragment of SQL.
Methods
impl<Query, Value> UncheckedBind<Query, Value> where
Query: Expression,
[src]
Query: Expression,
pub fn sql(self, sql: &str) -> SqlLiteral<Query::SqlType, Self>
[src]
Use literal SQL in the query builder
This function is intended for use when you need a small bit of raw SQL in
your query. If you want to write the entire query using raw SQL, use
sql_query
instead.
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.
Examples
let query = users .select(name) .filter( sql("id > ") .bind::<Integer,_>(1) .sql(" AND name <> 'Ryan'") ) .get_results(&connection); let expected = vec!["Tess".to_string()]; assert_eq!(Ok(expected), query);
