Struct oracle::ObjectType

pub struct ObjectType { /* fields omitted */ }

Type information about Object or Collection data type

This is for not only Object type information but also collection type information.

Examples

Gets MDSYS.SDO_GEOMETRY object type information.

let conn = Connection::connect("scott", "tiger", "", &[])?;
let objtype = conn.object_type("MDSYS.SDO_GEOMETRY");

Gets object type infomration in query.

let conn = Connection::connect("scott", "tiger", "", &[])?;
// conn.execute("create table location (name varchar2(60), loc sdo_geometry)", &[]);
let mut stmt = conn.prepare("select loc from location where name = '...'", &[])?;
let rows = stmt.query(&[])?;
let objtype = if let OracleType::Object(ref objtype) = *rows.column_info()[0].oracle_type() {
    objtype
} else {
    panic!("Not an object type")
};

Methods

impl ObjectType

pub fn schema(&self) -> &str

Gets schema name

pub fn name(&self) -> &str

Gets object name

pub fn is_collection(&self) -> bool

True when it is a collectoin. Otherwise false.

pub fn element_oracle_type(&self) -> Option<&OracleType>

Gets the Oracle type of elements if it is a collection. Otherwise, None.

pub fn num_attributes(&self) -> usize

Gets the number of attributes if it isn't a collection. Otherwise, 0.

pub fn attributes(&self) -> &[ObjectTypeAttr]

Gets a vector of attribute information if it isn't a collection. Otherwise, a zero-length vector.

Examples

Prints attribute information of MDSYS.SDO_GEOMETRY.

let conn = Connection::connect("scott", "tiger", "", &[])?;
let objtype = conn.object_type("MDSYS.SDO_GEOMETRY")?;
for attr in objtype.attributes() {
    println!("{:-20} {}", attr.name(), attr.oracle_type());
}

pub fn new_object(&self) -> Result<Object>

Create a new Oracle object.

pub fn new_collection(&self) -> Result<Collection>

Create a new collection.
