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 func-
tion can be called multiple times to send the parts of a character or bi-
nary 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. Parame-
ters 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).
See also
* mysql_stmt_execute(3).
