    用sqlldr从mysql导出一个表的数据到oracle


    代码:--------------------------------------------------------------------------------
    1 进入mysql
    mysql> select UUID, CYC_CODE, b03_05, b03_06, b03_07, b03_08, b03_09, b03_10, b03_11, b03_12, Cate_Item_Code, product_name, product_unit
    from  jb603_jb603_sub3 into outfile 'd:/tmp/603sub.txt';

    Query OK, 79537 rows affected (0.48 sec)
    mysql> show create table jb603_jb603_sub3;

    | jb603_jb603_sub3 | CREATE TABLE `jb603_jb603_sub3` (
      `UUID` varchar(32) NOT NULL default '',
      `CYC_CODE` char(2) NOT NULL default '',
      `b03_05` decimal(11,2) default '0.00',
      `b03_06` decimal(11,2) default '0.00',
      `b03_07` decimal(11,2) default '0.00',
      `b03_08` decimal(11,2) default '0.00',
      `b03_09` decimal(9,0) default '0',
      `b03_10` decimal(11,2) default '0.00',
      `b03_11` decimal(11,2) default '0.00',
      `b03_12` decimal(11,2) default '0.00',
      `Cate_Item_Code` varchar(7) NOT NULL default '',
      `product_name` varchar(60) default '',
      `product_unit` varchar(20) default '',
      PRIMARY KEY  (`UUID`,`CYC_CODE`,`Cate_Item_Code`)
    ) TYPE=InnoDB |
    将语句料理整理成oracle支撑的花样:
     CREATE TABLE jb603_jb603_sub3 (
      UUID varchar(32) NOT NULL ,
      CYC_CODE char(2) NOT NULL ,
      b03_05 number(11,2) ,
      b03_06 number(11,2) ,
      b03_07 number(11,2) ,
      b03_08 number(11,2) ,
      b03_09 number(9,0) ,
      b03_10 number(11,2) ,
      b03_11 number(11,2) ,
      b03_12 number(11,2) ,
      Cate_Item_Code varchar(7) NOT NULL ,
      product_name varchar(60) ,
      product_unit varchar(20) ,
      PRIMARY KEY  (UUID,CYC_CODE,Cate_Item_Code));
    2 编写sqlldr节制文件t.ctl
    load data
    infile 'd:/tmp/603sub.txt'
    into table   jb603_jb603_sub3
    replace
    fields terminated by x'09'
    (UUID, CYC_CODE, b03_05, b03_06, b03_07, b03_08, b03_09, b03_10, b03_11, b03_12, Cate_Item_Code, product_name, product_unit)
    3运转sqlplus /nolog
    SQL> conn lt/lt5@ibmlt
    建树jb603_jb603_sub3表
    SQL>  CREATE TABLE jb603_jb603_sub3 (
      2    UUID varchar(32) NOT NULL ,
      3    CYC_CODE char(2) NOT NULL ,
      4    b03_05 number(11,2) ,
      5    b03_06 number(11,2) ,
      6    b03_07 number(11,2) ,
      7    b03_08 number(11,2) ,
      8    b03_09 number(9,0) ,
      9    b03_10 number(11,2) ,
     10    b03_11 number(11,2) ,
     11    b03_12 number(11,2) ,
     12    Cate_Item_Code varchar(7) NOT NULL ,
     13    product_name varchar(60) ,
     14    product_unit varchar(20) ,
     15    PRIMARY KEY  (UUID,CYC_CODE,Cate_Item_Code));

    表已建树。
    4 ho进入独霸细碎命令行
    在独霸细碎命令走运转sqlldr lt/lt_5@ibmlt d:/tmp/t.ctl
    ....
    到达提交点,逻辑记载计数79537
    5 exit回到sqlplus

    SQL> select count(*)from JB603_JB603_SUB3;

      COUNT(*)
    ----------
         79537

    6别的,我不分明为什么用内部表方式不能成功
    sqlldr lt/lt5@ibmlt d:/tmp/t.ctl external_table=generate_only
    发作t.log

    用于加载内部表的 INSERT 语句:
    ------------------------------------------------------------------------
    INSERT /* append */ INTO JB603_JB603_SUB3
    (
      UUID,
      CYC_CODE,

      B03_11,
      B03_12,
      CATE_ITEM_CODE,
      PRODUCT_NAME,
      PRODUCT_UNIT
    )
    SELECT
      UUID,

      CATE_ITEM_CODE,
      PRODUCT_NAME,
      PRODUCT_UNIT
    FROM "SYS_SQLLDR_X_EXT_JB603_JB603_S"


    用于肃清由从前的语句建树的工具的语句:
    ------------------------------------------------------------------------
    DROP TABLE "SYS_SQLLDR_X_EXT_JB603_JB603_S"


    从日曜日 3月  26 13:11:41 2006初步运转
