[−][src]Struct odbc_api::handles::Description
Wraps a valid description handle.
Implementations
impl<'d> Description<'d>[src]
pub unsafe fn new(handle: HDesc) -> Self[src]
Safety
handle must be a valid description handle.
pub fn set_field_precision(
&mut self,
column_number: SmallInt,
precision: Integer
) -> Result<(), Error>[src]
&mut self,
column_number: SmallInt,
precision: Integer
) -> Result<(), Error>
pub fn set_field_scale(
&mut self,
column_number: SmallInt,
scale: Integer
) -> Result<(), Error>[src]
&mut self,
column_number: SmallInt,
scale: Integer
) -> Result<(), Error>
pub unsafe fn set_field_type(
&mut self,
column_number: SmallInt,
data_type: SqlDataType
) -> Result<(), Error>[src]
&mut self,
column_number: SmallInt,
data_type: SqlDataType
) -> Result<(), Error>
Safety
Overwrites the field type in the ARD record. This type may be used by odbc to determine buffer sizes and such.
pub unsafe fn set_field_concise_type(
&mut self,
column_number: SmallInt,
data_type: SqlDataType
) -> Result<(), Error>[src]
&mut self,
column_number: SmallInt,
data_type: SqlDataType
) -> Result<(), Error>
Safety
Overwrites the concise field type in the ARD record. This type may be used by odbc to determine buffer sizes and such.
