Struct c3p0_pool_mysql::json::C3p0JsonMysql

pub struct C3p0JsonMysql<DATA, CODEC: JsonCodec<DATA>> where
    DATA: Clone + Serialize + DeserializeOwned,  { /* fields omitted */ }

Methods

impl<DATA, CODEC: JsonCodec<DATA>> C3p0JsonMysql<DATA, CODEC> where
    DATA: Clone + Serialize + DeserializeOwned, 

pub fn fetch_one_with_sql(
    &self,
    conn: &MysqlConnection,
    sql: &str,
    params: &[&dyn ToValue]
) -> Result<Option<Model<DATA>>, C3p0Error>

Allows the execution of a custom sql query and returns the first entry in the result set. For this to work, the sql query:

• must be a SELECT
• must declare the ID, VERSION and DATA fields in this exact order

pub fn fetch_all_with_sql(
    &self,
    conn: &MysqlConnection,
    sql: &str,
    params: &[&dyn ToValue]
) -> Result<Vec<Model<DATA>>, C3p0Error>

Allows the execution of a custom sql query and returns all the entries in the result set. For this to work, the sql query:

• must be a SELECT
• must declare the ID, VERSION and DATA fields in this exact order
