[−][src]Struct hdbconnect::PreparedStatement
Allows injection-safe SQL execution and repeated calls of the same statement with different parameters with as few roundtrips as possible.
Methods
impl PreparedStatement[src]
impl PreparedStatementpub fn parameter_descriptors(&self) -> Option<&Vec<ParameterDescriptor>>[src]
pub fn parameter_descriptors(&self) -> Option<&Vec<ParameterDescriptor>>Descriptors of all parameters of the prepared statement (in, out, inout), if any.
pub fn input_parameter_descriptors(&self) -> Option<&Vec<ParameterDescriptor>>[src]
pub fn input_parameter_descriptors(&self) -> Option<&Vec<ParameterDescriptor>>Descriptors of the input (in and inout) parameters of the prepared statement, if any.
pub fn add_batch<T: Serialize>(&mut self, input: &T) -> HdbResult<()>[src]
pub fn add_batch<T: Serialize>(&mut self, input: &T) -> HdbResult<()>Converts the input into a row of parameters for the batch, if it is consistent with the metadata.
pub fn add_row_to_batch(&mut self, row: Vec<HdbValue>) -> HdbResult<()>[src]
pub fn add_row_to_batch(&mut self, row: Vec<HdbValue>) -> HdbResult<()>Consumes the input as a row of parameters for the batch.
Useful mainly for generic code.
In most cases add_batch()
is more convenient.
pub fn execute_batch(&mut self) -> HdbResult<HdbResponse>[src]
pub fn execute_batch(&mut self) -> HdbResult<HdbResponse>Executes the statement with the collected batch, and clears the batch.
