mysql导入数据到oracle中。

建立Oracle表：

CREATE TABLE "GG_USER" (
  "USERID" VARCHAR2(255 BYTE) NOT NULL,
  "ISPART" VARCHAR2(255 BYTE) DEFAULT NULL,
  "ACTUALPOSITIONID" NUMBER(11) DEFAULT NULL,
  "BEGINWORKTIME" TIMESTAMP(0) DEFAULT NULL,
  "BIRTHDAY" TIMESTAMP(0) DEFAULT NULL,
  "CARDNO" VARCHAR2(255 BYTE) DEFAULT NULL,
  "EMAIL" VARCHAR2(255 BYTE) DEFAULT NULL,
  "GENDERID" NUMBER(11) DEFAULT NULL,
  "HEALTHID" NUMBER(11) DEFAULT NULL,
  "HOME" VARCHAR2(255 BYTE) DEFAULT NULL,
  "IDENTIFY" VARCHAR2(255 BYTE) DEFAULT NULL,
  "LEAVEREASONID" NUMBER(11) DEFAULT NULL,
  "LEAVETIME" TIMESTAMP(0) DEFAULT NULL,
  "MOBILEPHONE" VARCHAR2(255 BYTE) DEFAULT NULL,
  "OFFICE" VARCHAR2(255 BYTE) DEFAULT NULL,
  "ORGID" VARCHAR2(255 BYTE) DEFAULT NULL,
  "ORGNAME" VARCHAR2(255 BYTE) DEFAULT NULL,
  "PASSWORD" VARCHAR2(255 BYTE) DEFAULT NULL,
  "POSITIONID" NUMBER(11) DEFAULT NULL,
  "REACHTIME" TIMESTAMP(0) DEFAULT NULL,
  "SORTSNO" NUMBER(11) DEFAULT NULL,
  "USERIMG" VARCHAR2(255 BYTE) DEFAULT NULL,
  "USERNAME" VARCHAR2(255 BYTE) DEFAULT NULL,
  "WORKSTATUSID" NUMBER(11) DEFAULT NULL,
  "STATUS" NUMBER(11) DEFAULT NULL,
  "CERTYPEID" NUMBER(11) DEFAULT NULL,
  "MINZUID" NUMBER(11) DEFAULT NULL,
  "PERSONID" VARCHAR2(255 BYTE) DEFAULT NULL,
  PRIMARY KEY ("USERID")
)

执行mysql数据导出命令：

mysql  -uroot -pD******** -Ne "use dsideal_db; select * from gg_user;" > /usr/local/mysql/gg_user.csv

编写sqlldr导入control文件

load data
CHARACTERSET ‘UTF8‘
infile ‘d:/gg_user.csv‘
replace into table GG_USER
fields terminated by X‘09‘
optionally enclosed by ‘"‘
(USERID NULLIF(USERID=‘NULL‘) ,ISPART NULLIF(ISPART=‘NULL‘) ,ACTUALPOSITIONID NULLIF(ACTUALPOSITIONID=‘NULL‘) ,BEGINWORKTIME  timestamp "yyyy-mm-dd" NULLIF(BEGINWORKTIME=‘NULL‘) ,BIRTHDAY timestamp "yyyy-mm-dd" NULLIF(BIRTHDAY=‘NULL‘) ,CARDNO NULLIF(CARDNO=‘NULL‘) ,EMAIL NULLIF(EMAIL=‘NULL‘) ,GENDERID NULLIF(GENDERID=‘NULL‘) ,HEALTHID NULLIF(HEALTHID=‘NULL‘) ,HOME NULLIF(HOME=‘NULL‘) ,IDENTIFY NULLIF(IDENTIFY=‘NULL‘) ,LEAVEREASONID NULLIF(LEAVEREASONID=‘NULL‘) ,LEAVETIME  timestamp "yyyy-mm-dd" NULLIF(LEAVETIME=‘NULL‘) ,MOBILEPHONE NULLIF(MOBILEPHONE=‘NULL‘) ,OFFICE NULLIF(OFFICE=‘NULL‘) ,ORGID NULLIF(ORGID=‘NULL‘) ,ORGNAME NULLIF(ORGNAME=‘NULL‘) ,PASSWORD NULLIF(PASSWORD=‘NULL‘) ,POSITIONID NULLIF(POSITIONID=‘NULL‘) ,REACHTIME timestamp "yyyy-mm-dd" NULLIF(REACHTIME=‘NULL‘) ,SORTSNO NULLIF(SORTSNO=‘NULL‘) ,USERIMG NULLIF(USERIMG=‘NULL‘) ,USERNAME NULLIF(USERNAME=‘NULL‘) ,WORKSTATUSID NULLIF(WORKSTATUSID=‘NULL‘) ,STATUS NULLIF(STATUS=‘NULL‘) ,CERTYPEID NULLIF(CERTYPEID=‘NULL‘) ,MINZUID NULLIF(MINZUID=‘NULL‘) ,PERSONID NULLIF(PERSONID=‘NULL‘))

执行sqlldr导入操作

sqlldr userid=‘dsideal/dsideal‘ control=‘d:/ctl.ctl‘ log=‘d:/ctl.log‘
