The SQL Server query processor treats indexed and nonindexed views differently:The rows of an indexed view are stored in the database in the same format as a table. If the Query Optimizer decides to use an indexed view in a query plan, the indexed view is treated the same way as a ...

44、当服务器的内存够多时,配制线程数量 = 最大连接数+5,这样能发挥最大的效率;否则使用 配制线程数量 <最大连接数启用SQL SERVER的线程池来解决,如果还是数量 = 最大连接数+5,严重的损害服务器的性能。 45、按照一定的次序来访问你的表。如果你先锁住表A,再锁住表B,那么在所有的存储过程中都要按照这个顺...
