批量增加数据脚本add_batch.sql 

 

Java代码  

create function add_account(INTEGER) returns TEXT as '  

DECLARE  

num INTEGER := 1;   

input_num ALIAS FOR $1;  

number INTEGER := 0;    

BEGIN   

    number :=num+input_num;  

    WHILE num

        insert into tbl_real_net (real_id,net_id)  

         values( num,num +1);  

        num :=num +1;  

    end loop;  

    RETURN ''增加成功'';  

END;'   

language 'plpgsql';
