The performance of batched search when applied to index sequential files is studied. Analysis provides exact formulae for the cost of searching when batching is applied as a function of the magnitude of the quer
如果是二级索引,需要做两个判断: // 1)事务可见性判断:PAGE_MAX_TRX_ID 是否小于 read view 里的 m_up_limit_id // 当然,这只是一个粗糙的判断 // 2)ICP 判断:判断 rec 是否满足 ICP(index condition pushdown) switch (row_search_idx_cond_check(buf, prebuilt, rec, offsets)) { case ICP_NO...
Step 1 - Perform a case sensitive search (partial match) The FIND function returns a number representing the position of a specific substring in another string, reading left to right. Note, the FIND function is case-sensitive. FIND(F2, B3:B8) becomes FIND("E", {"Cat"; "Horse"; "Snake...

However, the metric learned index is unable to directly work on trajectory data as it does not impose sequential relationships. In addition, it requires a prebuild tree index to perform both training and search for similar objects. Deep learning-based approaches on similarity search: Several deep...
Queries in which a sequential search is specified, such as WHERE ProductID BETWEEN 980 and 999, would benefit from a clustered index on ProductID. This is because the rows would be stored in sorted order on that key column. Defined as IDENTITY. Used frequently to sort the data ret...
