plsql数据导入

1.当数据量较小的时候，将excel的字段整理成和数据库表字段的顺序一致，然后复制excel中的数据，表名： table
执行：

select * from table for update

选中第一列，右键复制即可。
2.数据量较大时，利用plsql的***TextImport***进行数据的导入

1. 将exce文件另存为文本文件
   
   2.打开plsql的TextImport
   
   选择生成的文本文件
   3.选择要导入的表，以及相应字段
   
   最后点左下角的import就可以了~。

这里的采用随机生成的uuid

二、导入excel文件（这里需要注意excel中的字段类型要与导入目标数据库表中的字段一 一对应，这里可以提前写好）

选中表，点击切换上面的Data to Oracle  

 general下 点击table,下拉栏，选中对应的数据库，如何excel表中的字段名一致，plsql会自动匹配。选完之后需要点击一下fields中任意一个字段才能点击下方的import按钮，import之前，检查一下第三步的字段名、字段类型是否一致。

 完成之后记得查询一下数据，如何对插入的不满意，直接delete 再来一次就好。

附加：

在oracle sql中自带select sys_guid() from dual;  guid方法。

百度搜：拾取坐标系统。

在数据库中使用sql语句，循环添加数据，亲测 有效：

1. BEGIN
2. for i in 1 .. 138 //循环138次
3. loop
4. insert into 表名 (表字段) VALUES (sys_guid());
5. end loop;
6. commit;
7. end;

一、想通过plsql在表中直接添加一条记录点击小锁的时候，出现如下错误：These query results are not updateable.Include the ROWID to get updateable results. 如截图：

解决方法：

1、查询语句后面加for update：select *  from  CBS_CATV_SMARTCARD where usercode ='9002733' for update ;

2、加rowid字段：select CBS_CATV_SMARTCARD.*,rowid from  CBS_CATV_SMARTCARD where usercode ='9002733' ;

二、添加好后点击‘+’按钮，插入记录，然后点击页面中的勾记入改变，最后点击commit提交按钮。

下面是截得别人的笔记，还不错，从来没用过回滚，以前都没关注过，好用的按钮啊
