If you used a previous version of SQL Server, you could create your own table-valued function to split a string based on a specific delimiter. You can refer to the following topics onwww.stackoverflow.comfor many examples: 如果使用SQL Server的早期版本,则可以创建自己的表值函数来基于特定的定界...
The splitting operation accomplished by the "\w+" expression in this case could be just as easily accomplished with the String.Split method, which would be much faster. Regular expressions are a very powerful tool, but do make sure when you use them that you're using ...

You can't use a static query and have SQL Server figure out all distinct values in OrderYear. To achieve this, you have to use dynamic execution to construct the query string dynamically, as the code in Figure 13 shows. Figure 13 Constructing a Dynamic Query String Copy CREATE INDEX idx...
