在存储过程中使用正则表达式 [英] Using regular expression within a stored procedure

问题描述

启用除字符之外的所有输入的正则表达式模式是什么?到目前为止，这就是我所拥有的 -

What is the regular expression pattern that enables every input besides characters? So far this is what i have -

CREATE PROCEDURE Paging_Movies
@alphaChar char(1)
AS
if @alphaChar = '#'
select * from Movies where movies like '[0-9]%'
else
select * from Movies where movies like @alphaChar + '%'

推荐答案

如果您想要真正的正则表达式模式匹配，您将需要推出自己的 CLR UDF.此链接介绍了如何执行此操作:

If you want true regular expression pattern matching you will need to roll your own CLR UDF. This link goes over how to do that:

请记住，您只能在 SQL Server 2005 或更高版本中执行此操作.

Keep in mind that you can only do this in SQL Server 2005 or higher.

如果您只想要非 alpha，您可以这样做:

If you just want non-alpha you can do this:

'([^a-z])'

这里是 SQL Server like 的文档:
