db2 => connect to sample
数据库连接信息
数据库服务器 = DB2/NT 9.5.0
SQL 授权标识 = YANG
本地数据库别名 = SAMPLE
db2 => export to d:\employee.ixf of ixf messages d:\employee.msg select * from a
dministrator.employee
导出的行数：42
db2 => export to d:\employee.del of del messages d:\employee_del.msg select * fr
om administrator.employee
导出的行数：42
db2 => export to d:\employee.wsf of wsf messages d:\employee_wsf.msg select * fr
om administrator.employee
导出的行数：42
EXPROT 支持三种文件格式 IXF ,DEL,WSF;虽然export不支持ASC文件类型，但是可以通过修改select 语句而生成ASC 类型的数据文件 给个例子：
db2 => export to d:\employee.del of del select firstnme concat empno from administrator.employee
SQL3104N EXPORT 实用程序 正在开始将数据导出至文件 "d:\employee.del"。
SQL3105N Export 实用程序已经完成导出 "42" 行。
导出的行数：42
结果如下：
"CHRISTINE000010"
"VINCENZO000110"
"SEAN000120"
"DIAN200010"
"GREG200120"
"MICHAEL000020"
"SALLY000030"
"DELORES000130"
"HEATHER000140"
"KIM200140"
"IRVING000060"
"BRUCE000150"
"ELIZABETH000160"
当导入数据时，第一列的起始位置为2，这样可以忽略掉第一个位置的双引号 " 字符。
导出时派生别名：不过只有IXF,WSF这两种格式支持。
db2 => export to d:\staff.ixf of ixf select salary-comm as pay from administrator.staff
SQL3104N EXPORT 实用程序 正在开始将数据导出至文件 "d:\staff1.ixf"。
SQL27984W 成功地完成 Export 命令。在导出期间，尚未将某些重新创建信息保存至
PC/IXF 文件。此文件在 Import CREATE 方式下将不受支持。原因码 = "7"。
SQL3105N Export 实用程序已经完成导出 "70" 行。
导出的行数：70
还可以这样写
db2 =>export to d:\staff.ixf of ixf method ('pay',...) select salary-comm ,... from administrator.staff
--处理十进制数据列使用 decpt跟上一个特殊字符 可以修改小数点定界符。

修改之后的效果

--处理日期：del 和wsf 默认的日期格式为 yyyymmdd 用户可以通过使用datesiso 来将日期格式修改为yyyy-mm-dd
db2 => export to d:\sales.del of del modified by datesiso select * from a
