For a partitioned index, the query optimizer uses the default sampling algorithm instead of scanning all the rows in the table for a nonpartitioned index. To obtain statistics on partitioned indexes by scanning all the rows in the table, use CREATE STATISTICS or UPDATE STATISTICS with the ...

but the leaf node of the last layer will be reached. For example, when we search for id=3, although it hits directly in the first layer, all the data is on the leaf node, so I will continue to search down to the
Step 2 - Perform a second case sensitive search (partial match) FIND(G5, C5:C10) becomes FIND("M",{"small";"SMALL";"LaRgE";"SmAlL";"sMall";"small"}) and returns {#VALUE!; 2; #VALUE!; #VALUE!; 2; #VALUE!}. Step 3 - Multiply arrays The formula returns a value if both sub...
Apply Algorithm 1 (DeepSuperpositionSearch) to find the most favorable superpositions through a deep search using spatial indices. The search depth is controlled with the --speed option. This step is central to the GTalign method because it enables rapid exploration of the superposition space, resu...
The main process of the SNESIM algorithm is as follows: 1. Pre-scan TI and Build the Search Tree: Assign sample data to the nearest grid nodes and define a random path to traverse all unsampled nodes. Check if the current node is on the simulation grid; if it is, continue; otherwise...
