在SELECT INTO OUTFILE 语句中可以指定FILECOUNT 参数指定并行导出的文
件个数，
文件命名方式为file_title+suffix+file_ext 形式，
其中file_title 是file_name
中’.’之前的部分，file_ext 为file_name 中’.’之后的部分（包含’.’）suffix
为自动追加的文件名后缀，第一个文件名后缀是“_1”,以此类推。
示例
示例1：指定导出的文件个数FILECOUNT（本地导出时本参数不起作用）。
示例中所用的表及数据：
DROP TABLE IF EXISTS test;
CREATE TABLE test (ps_partkey bigint,ps_suppkey bigint,ps_availqty
bigint,ps_supplycost decimal(15,2),ps_comment varchar(200));
gbase>select * from test;
