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 char-
acter 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. Pa-
rameters 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_exe-
cute(3).
• bound variables for this column will be ignored when calling
mysql_stmt_execute(3).
See also
• mysql_stmt_execute(3).
