Trait oracle::ToSqlNull

pub trait ToSqlNull {
    fn oratype_for_null() -> Result<OracleType>;
}

A trait specifying Oracle type to bind a null value.

This trait is used only when binding a None value of Option<T>. The type of the null value is determined by the rust type.

Rust Type	Oracle Type
str, String	nvarchar2(0)
i8, i16, i32, i64, u8, u16, u32, u64, f32, f64	number
Vec<u8>	raw(0)
bool	boolean (PL/SQL only)
Timestamp	timestamp(9) with time zone
IntervalDS	interval day(9) to second(9)
IntervalYM	interval year(9) to month

When chrono feature is enabled, the followings are added.

Rust Type	Oracle Type
chrono::Date	timestamp(0) with time zone
chrono::DateTime	timestamp(9) with time zone
chrono::naive::NaiveDate	timestamp(0)
chrono::naive::NaiveDateTime	timestamp(9)
chrono::Duration	interval day(9) to second(9)
