The advantage of recursive programming is that it is very easy to write and it only requires very few lines of code if done correctly.Structured query language(SQL)is a database language and is used to manipulate data.In Microsoft SQL Server 2000,recursive queries are implemented to retrieve data which is presented in a hierarchical format,but this way has its disadvantages.Common table expression(CTE)construction introduced in Microsoft SQL Server 2005 provides the significant advantage of being able to reference itself to create a recursive CTE.Hierarchical data structures,organizational charts and other parent-child table relationship reports can easily benefit from the use of recursive CTEs.The recursive query is illustrated and implemented on some simple hierarchical data.In addition,one business case study is brought forward and the solution using recursive query based on CTE is shown.At the same time,stored procedures are programmed to do the recursion in SQL.Test results show that recursive queries based on CTEs bring us the chance to create much more complex queries while retaining a much simpler syntax. 展开更多

普遍真理与普世伦理的根据都只能在人那里寻找,前者着眼于人的话语形式的普遍性,后者立足于人性中的普遍性情感要求。但是,多样性、差异性就是生活本身,探求多样中是否存在某种一致、差异是否可能达成某种统一尽管是哲学追问的不懈动力... 普遍真理与普世伦理的根据都只能在人那里寻找,前者着眼于人的话语形式的普遍性,后者立足于人性中的普遍性情感要求。但是,多样性、差异性就是生活本身,探求多样中是否存在某种一致、差异是否可能达成某种统一尽管是哲学追问的不懈动力,但实际上这种"一致"、"统一"可能只是经验性的假设前提。 展开更多
