当涉及到大量提取数据库数据并进行计算而导致提取效率太低的情况时，可以先利用存储过程先行编写提取并计算数据的代码，这样在aspx.cs后台中就可以直接调用存储过程了，提高了数据执行效率。-When it comes to massive withdrawals of　data and calculation result in extraction efficiency is too low, you can use stored procedures written in advance and calculates code data extraction, so aspx.cs background can directly call a stored procedure, and to improve data efficiency.
