ANSI | Sidney's Blog

http://dbsid.com/tag/ansi

最近一个case, 使用ANSI JOIN时, 使用cardinality(view name.table name 1000000000) 这个hint不起作用. The view name.table name notation for global hints does not work for queries using ANSI join syntax because the optimizer generates additional views during parsing. When using ANSI join syntax, specify the query block name in the hint instead of theview name.table name notation. 重现一下, 准备两个表t1, t2. Create or replace view v as select * from t2;. Cardinality(v.t2 1000000000)这个hint对oracle join语法生效.

maxvalue | Sidney's Blog

http://dbsid.com/tag/maxvalue

假设range分区使用多个分区键, 比如这个示例中的(month id, status id). 如果常用查询条件为month id=201407, 我们会期望分区裁剪之后, 只有201407开头分区会被扫描. 实际情况如何, 我们做个简单的实验:. 创建两个结构相同的表t1和t2, 只是每个月最后的一个分区第二个分区键的high value不同, t1为’V40′, t2为maxvalue. 使用条件month id=201407扫描数据, 观察执行计划中的pstart, pstop. 对于表t1, 因为201407的最后一个分区p 201407 V40的high value为(201407,’V40′), 那可能出现(201407,’ZZZ’)的数据大于(201407,’V40′), 需要放到201408的第一个分区p 201408 V10. 所以使用条件month id=201407时, 必须扫描p 201408 V10这个分区, 此时执行计划中pstat=1, pstop=5.

Della Morte alla Vita | Filipi 1:21

Della Morte alla Vita. On February 7, 2012. Ciao, è passato tanto tempo da quando l’ultima volta che ho bloggato e tante storie da raccontare, ma questa volta non ho intenzione di entrare nei dettagli di tutto ciò che è accaduto. Ospita ogni fine anno. Non sto dicendo che tutti dovrebbero lasciare tutto come ho fatto io, quello che sto dicendo è che diventiamo vincitori ogni volta che decidono ascoltare e mettere in pratica ciò che Dio vi ha chiamati a fare.
