[−][src]Struct hdbconnect::FieldMetadata
Metadata of a field in a ResultSet.
Implementations
impl FieldMetadata[src]
pub fn schemaname(&self) -> &str[src]
Database schema of the field.
pub fn tablename(&self) -> &str[src]
Database table.
pub fn columnname(&self) -> &str[src]
Column name.
pub fn displayname(&self) -> &str[src]
Display name of the column.
pub fn type_id(&self) -> TypeId[src]
Returns the id of the value type.
pub fn is_nullable(&self) -> bool[src]
True if column can contain NULL values.
pub fn precision(&self) -> i16[src]
The length or the precision of the value.
Is -1 for LOB types.
pub fn scale(&self) -> i16[src]
The scale of the value.
Is 0 for all types where a scale does not make sense.
pub fn has_default(&self) -> bool[src]
Returns true if the column has a default value.
pub fn is_read_only(&self) -> bool[src]
Returns true if the column is read-only.
pub fn is_auto_incremented(&self) -> bool[src]
Returns true if the column is auto-incremented.
pub fn is_array_type(&self) -> bool[src]
Returns true if the column is of array type.
