[−][src]Trait oracle::sql_type::FromSql
Conversion from Oracle values to rust values.
Values in Oracle are converted to Rust type as possible as it can. The following table indicates supported conversion.
Oracle Type | Rust Type |
---|---|
character data types | String |
" | i8, i16, i32, i64, isize, u8, u16, u32, u64, usize, f64, f32 by using String.parse() |
" | Vec<u8> (The Oracle value must be in hexadecimal.) |
" | Timestamp by String.parse() |
" | IntervalDS by String.parse() |
" | IntervalYM by String.parse() |
numeric data types | i8, i16, i32, i64, isize, u8, u16, u32, u64, usize, f64, f32 |
" | String |
raw | Vec<u8> |
" | String (The Oracle value is converted to characters in hexadecimal.) |
timestamp data types | Timestamp |
" | String |
interval day to month | IntervalDS |
" | String |
interval year to month | IntervalYM |
" | String |
Oracle object except Oracle collection | Object |
" | String |
Oracle collection | Collection |
" | String |
boolean (PL/SQL only) | bool |
When chrono
feature is enabled, the followings are added.
Oracle Type | Rust Type |
---|---|
timestamp data types | chrono::DateTime |
" | chrono::Date |
" | chrono::naive::NaiveDateTime |
" | chrono::naive::NaiveDate |
interval day to second | chrono::Duration |
This conversion is used also to get values from output parameters.
