您要查找的是不是：
- The organic maturity of lower Palaeozoic in the eastern Yangzi Gorges area is studied by means of a new technique of kerogen infrared spectroscopy,combined with conodont color alteration index. 应用干酪根红外光谱技术，结合牙形石色变指数分析了峡东地区下古生界有机质成熟度。探讨了在缺乏镜质体的前泥盆纪地层和海相地层中分析有机质成熟度或古地温的另一有效途径。
- Conodont color alteration index; 牙形石色变指标;
- To execute ALTER INDEX, at a minimum, ALTER permission on the table or view is required. 若要执行ALTER INDEX,至少需要对表或视图具有ALTER权限。
- By default, the ALTER INDEX REORGANIZE statement compacts pages that contain large object (LOB) data. 默认情况下,ALTER INDEX REORGANIZE语句将压缩包含大型对象(LOB)数据的页。
- Also, ALTER INDEX REORGANIZE will compact an index by trying to fill pages to the FILLFACTOR that was last specified. 此外,ALTER INDEX REORGANIZE还试图通过将页填充到上一次指定的FILLFACTOR来压缩索引。
- These values provide a rough guideline for determining the point at which you should switch between ALTER INDEX REORGANIZE and ALTER INDEX REBUILD. 这些值提供了一个大致指导原则,用于确定应在ALTER INDEX REORGANIZE和ALTER INDEX REBUILD之间进行切换的点。
- Use ALTER INDEX REORGANIZE, the replacement for DBCC INDEXDEFRAG, to reorder the leaf level pages of the index in a logical order. 使用ALTER INDEX REORGANIZE(代替DBCC INDEXDEFRAG)按逻辑顺序重新排序索引的叶级页。
- When you execute ALTER INDEX REORGANIZE with or without LOB_COMPACTION, the max degree of parallelism value is a single threaded operation. 当执行带有或不带LOB_COMPACTION的ALTER INDEX REORGANIZE语句时,max degree of parallelism值属于单线程操作。
- This means long-term blocking table locks are not held and queries or updates to the underlying table can continue during the ALTER INDEX REORGANIZE transaction. 这意味着不保留长期阻塞的表锁,且对基础表的查询或更新可以在ALTER INDEX REORGANIZE事务处理期间继续。
- Use the ALTER INDEX REBUILD statement with the ONLINE option to perform an index rebuild online, or to control the degree of parallelism during the index rebuild operation. 使用具有ONLINE选项的ALTER INDEX REBUILD语句执行联机索引重新生成,或控制索引重新生成操作期间的并行度。
- The ALTER INDEX statement can be used to rebuild an index part of a constraint definition; the constraint does not have to be dropped and added again with ALTER TABLE. ALTER INDEX语句可用于重新生成约束定义的索引部分;而不必再使用ALTER TABLE来删除和添加约束。
- You can use the CREATE INDEX or ALTER INDEX statements to set the fill factor value for individual indexes. 可以使用CREATE INDEX或ALTER INDEX语句来设置各个索引的填充因子值。
- On multiprocessor computers, just like other queries do, ALTER INDEX REBUILD automatically uses more processors to perform the scan and sort operations that are associated with modifying the index. 在多处理器计算机中,就像其他查询那样,ALTER INDEX REBUILD自动使用更多处理器来执行与修改索引相关联的扫描和排序操作。
- The ALTER INDEX ALL REBUILD statement rebuilds and enables all disabled indexes on the table, except for disabled indexes on views. ALTER INDEX ALL REBUILD语句将重新生成并启用表的所有已禁用索引(视图的已禁用索引除外)。
- The allocation of free space in table spaces and indexes is determined by the PCTFREE and FREEPAGE options of the CREATE or ALTER TABLESPACE and CREATE or ALTER INDEX statements. 表空间和索引中空余空间的分配是由CREATE或ALTER TABLESPACE以及CREATE或ALTER INDEX语句的PCTFREE和FREEPAGE选项确定的。
- THE RELATIONSHIP BETWEEN CONODONT COLOR ALTERATION INDEX AND ORGANIC MATTER MATURITY OF THE ORDOVICIAN HYDROCARBON SOURCE ROCKS IN KULUKETAGE DISTRICT, TARIM BASIN 塔里木盆地库鲁克塔格奥陶系牙形石色变指标与有机质成熟度的关系
- No one can alter the fact, ex post facto. 没有人能在事后改变事实本身。
- There is a structural alteration to the building. 这座建筑物在这有一处结构上的改变。
- SQL> alter index testb_idx monitoring usage; 监视索引有没有被使用过。
- A small alteration, adjustment, or limitation. 更改小小的改变，调正或限制
