In this post, I introduced how SQL Server 2005 implements query plans on partitioned tables. If you've read that post or used partitioned tables, you may recall that SQL Server 2005 uses a constant scan operator
In SQL Server 6.5 and earlier, partitioning had to be part of your design and built into all of your data access coding and querying practices. By creating multiple tables, and then managing access to the correct tables through stored procedures, views, or client applications, you could often ...

The query performance comparison of the two tables in this scenario: For the associated query between the partition table and the ordinary table, the execution time is 6.76 seconds. localhost:ytt>select count(*) from t1_no_pt a inner join t1 b using(id); ...
For OBS multi-temperature tables: The tablespace of a partitioned table cannot be set to an OBS tablespace during theMOVE,EXCHANGE,MERGE, andSPLIToperations. When anALTERstatement is executed, the cold and hot data attributes in the partitions cannot be changed, that is, data in the cold part...
ALGORITHM=1 causes the server to use the same key-hashing functions as MySQL 5.1 when computing the placement of rows in partitions; ALGORITHM=2 means that the server employs the key-hashing functions implemented and used by default for new KEY partitioned tables in MySQL 5.5 and later. (...
