Description

This module contains functions these are responsible for processing prepared statements.

Function Index

pack_null_bit_map/2	Generates binary that represents null bit map - definition of parameters with NULL value.
pack_parameters/2	The function converts list of parameters to binary that is prepared to form statement execute command.
pack_types/1	The function converts list of constants representing a MySQL types of prepared statement parameters to binary().

Function Details

pack_types/1

pack_types(Types::[mysql_type()]) -> binary()

mysql_type() = integer()

The function converts list of constants representing a MySQL types of prepared statement parameters to binary(). The binary will be inserted to prepared statement execution command.

pack_parameters/2

pack_parameters(Types, Params) -> binary()

Types = [integer()]
Params = [integer() | float() | string() | binary() | #mysql_time{} | #mysql_decimal{}]

The function converts list of parameters to binary that is prepared to form statement execute command.

pack_null_bit_map/2

pack_null_bit_map(Parameter_types, Parameters) -> binary()

Parameter_types = [integer()]
Parameters = [integer() | float() | string() | binary() | #mysql_time{} | #mysql_decimal{}]

Generates binary that represents null bit map - definition of parameters with NULL value.
