  Name

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).
