声明一个含有某张表不具备字段的游标

其中,data.*是一张表，然后把其他表中的字段也加到sal_data的游标中

 

cursor sal_data(cp_center_temp_id varchar2) is      select data.*,             post.id               emp_post_id,             doc.Salary_Tax_Bd     sa_tax_bd,             batch.bill_year_month bill_year_month,             batch.id              batch_id,             post.emp_id           employee_id        from sa_salary_data data        left join sa_salary_batch batch          on data.sa_batch_id = batch.id        left join sa_salary_document doc          on data.sa_doc_id = doc.id        left join pb_emp_post post          on doc.emp_post_id = post.id        left join pb_send send          on post.send_id = send.id       where send.cost_center_id = cp_center_temp_id;

 

使用此游标：

声明一个此游标类型的变量:

salary_data_temp sal_data%rowtype;

 

然后编译此游标

open sal_data(center_temp.id);        loop          fetch sal_data            into salary_data_temp;          exit when sal_data%notfound;--TODOend loop;colse sal_data;
