步骤：
1. 创建表
2.准备平面文件
3.准备CTL文件
4. 把平面文件和ctl文件上传到服务器
5.在sql editor中执行import语句
在操作过程中，只需要根据以下样例准备数据即可。
创建相应的表结构：
CREATE COLUMN TABLE "STUDENT"."CUSTOMER" ("ORDERID" INTEGER CS_INT NOT NULL ,
"CUSTOMERID" INTEGER CS_INT,
"EMPLOYEEID" INTEGER CS_INT,
"ORDERDATE" LONGDATE CS_LONGDATE,
"REQUIREDDATE" LONGDATE CS_LONGDATE,
"SHIPPEDDATE" LONGDATE CS_LONGDATE,
"PROMOTION_ID" INTEGER CS_INT,
"PERIODID" INTEGER CS_INT,
"DELIVEREDDATE" LONGDATE CS_LONGDATE,
PRIMARY KEY ("ORDERID"));
准备相应的CSV文件：
准备CTL文件：
import data
into table "STUDENT44"."CUSTOMER"
from 'STS_CUSTOMER.csv'
record delimited by '\n'
field delimited by ','
optionally enclosed by '"'
error log 'XTRA_STS_CUSTOMER.err'
上传文件到服务器相应的目录
在SQL Editor中运行以下语句：
IMPORT FROM '/backup/STS/STS_CUSTOMER.ctl';
UPDATE STUDENT44.CUSTOMER MERGE DELTA INDEX;
