mysql_stmt_send_long_data − Sends data in chunks

Synopsis

#include <mysql.h>


my_bool mysql_stmt_send_long_data(MYSQL_STMT * stmt,
                                  unsigned int,
                                  const char * data,
                                  unsigned long);

Description

Allows sending parameter data to the server in pieces (or chunks), e.g. if the size of a blob exceeds the size of max_allowed_packet size. This function can be called multiple times to send the parts of a character or binary data value for a column, which must be one of the TEXT or BLOB datatypes.

Parameter

	•		`stmt` − a statement handle, which was previously allocated by mysql_stmt_init(3).
	•		`param_no` − indicates which parameter to associate the data with. Parameters are numbered beginning with 0.
	•		`data` − a buffer containing the data to send.
	•		`long` − size of the data buffer.

Return value

Returns zero on success, nonzero if an error occurred.

Notes

	•		`mysql_stmt_send_long_data()` must be called before mysql_stmt_execute(3).
	•		bound variables for this column will be ignored when calling mysql_stmt_execute(3).
