Oracle批量插入数据的三种方式

第一种:

begin
    insert into tableName(column1, column2, column3...) values(value1,value2,value3...);
    insert into tableName(column1, column2, column3...) values(value1,value2,value3...);
    insert into tableName(column1, column2, column3...) values(value1,value2,value3...);
    ...
end;

第二种:

insert into tableName(column1, column2, column3...) values(value1,value2,value3...);
insert into tableName(column1, column2, column3...) values(value1,value2,value3...);
insert into tableName(column1, column2, column3...) values(value1,value2,value3...);

第三种(利用中间表):

insert into tableName(column1(主键),column2,column3...)
    select tableNames_seq.nextval,,column2,column3... from (
    select value1 column2,value2 column3,value3 column4 from dual
    union
    select value1 column2,value2 column3,value3 column4 from dual
    union
    select value1 column2,value2 column3,value3 column4 from dual
    union
    select value1 column2,value2 column3,value3 column4 from dual
)
