Hello,everyone!
My table has a bigint column which needs store 8bytes integer.
I looked up in Mysql Menual. It seems that , if I use C API I can only use

I can not use mysql_real_query or mysql_query to insert bigint values because I

This option is useful for dumping large tables. It forces mysqldump to
retrieve rows for a table from the server a row at a time rather than
retrieving the entire row set and buffering it in memory before writing
it out.
