hi，



光标只是一个for循环概念。当您返回一些记录集并使用相同的过程执行功能时。作为基本建议不要使用光标。它会产生很多性能问题。使用游标时执行时间越来越多。主要缺点是它在服务器上分配了大量内存。更好地使用临时表概念来避免游标。

Cursor is nothing but a for loop concept. While you returning some recordset and doing functionality with the same procedure. As the basic advise dont use cursor. It creates lot of performance issue. Executing time is getting more while used cursors. Main disadvantage is it allocates lot of memory on server. Better use temp table concept to avoid cursors.
