服务器端验证 [英] Server Side validation

问题描述

我想知道这是否可行，怎么办?
我有一个详细信息"视图，该视图用于插入和编辑SQL Server数据库中的字段.我创建了一个简单的函数，该函数遍历字段数组，然后检查它们是否都不为NULL，但是我还要检查它们是否不超过数据库可以接受的字段长度. 有办法以某种方式检索此信息吗?
然后，我可以检查输入的字段长度是否小于数据库的字段长度.如果没有其他想法
我该怎么办?
我如何进行服务器端验证?

推荐答案

您应限制输入时间本身的最大长度.但是，您会在INFORMATION_SCHEMA.COLUMNS对象中找到列的详细信息.

You should restrict the maximum length in time of entry itself. However you will find the details of columns in INFORMATION_SCHEMA.COLUMNS object.

您需要使用regularexpressionvalidator来检查输入到字段中的数据的长度.

You need to use regularexpressionvalidator to check the length of the data entered into the fields.
