◆ bind_param

mysql_service_status_t(* s_mysql_mysql_stmt_bind::bind_param) (my_h_statement statement, uint32_t index, bool is_null, uint64_t type, bool is_unsigned, const void *data, unsigned long data_length, const char *name, unsigned long name_length)

Bind a parameter.

Note: Calling bind with regular statements results in failure.; Bound values are cached. To update only some parameters, call bind on these, the rest will use the cached values.; Calling bind with the same index multiple times, only the last value is kept.

Parameters

[in]	statement	A handle to the statement
[in]	index	0-based index of the parameter to be bound
[in]	is_null	Whether the parameter can be null
[in]	type	Type of the parameter. List of supported types: Table 6.1 at https://dev.mysql.com/doc/c-api/8.0/en/c-api-prepared-statement-type-codes.html
[in]	bool	Whether the value is unsigned
[in]	data	The data argument is the value for the member
[in]	data_length	Length of the data
[in]	name	Name of the parameter
[in]	name_length	Name length of the parameter

Returns: Status of the performed operation
