ORACLE中的WHERE子句

Question

How to use WHERE clause while inserting values into the table? 在表中插入值时如何使用WHERE子句？

I tried the below query to insert values into the column, whichever set address='COB' 我尝试了以下查询以将值插入列，无论哪个设置了地址='COB'

insert into table empt (loc,country,mob)
values ('&loc','&country',&mob)
where address='COB';

Answer 1

This looks like you may need to use update if the field already exists in your table - 如果您的表格中已经存在该字段，则看起来您可能需要使用update

ie 即

update empt 
   set loc =?, country = ?, mob=? 
where address ='COB';

Answer 2

I don't know, why you are using "Table" in insert statement. 我不知道，为什么要在插入语句中使用“表”。

INSERT 插入

insert into empt (loc,country,mob)
values ('&loc','&country',&mob)

Hope you need Update. 希望您需要更新。

UPDATE 更新

Update empt
Set loc = '&loc',
country = '&country',
mob = &mob
where address='COB';

Please refer SQL Statements used in oracle 请参考oracle中使用的SQL语句

Answer 3

insert into table empt (loc,country,mob)
select loc,country,&mob
where address='COB';
