To set different types of data compression for different partitions, specify the DATA_COMPRESSION option more than once, for example:SQL Copy --For rowstore tables REBUILD WITH ( DATA_COMPRESSION = NONE ON PARTITIONS (1), DATA_COMPRESSION = ROW ON PARTITIONS (2, 4, 6 TO 8), DATA_...
For servers that have hyper-threading enabled, theMAXDOPvalue should not exceed the number of physical processors. These aregeneral guidelines only. There may be some exceptions to these guidelines. For example, do not use the guidelines under the following conditions: If the server is not an on...
If you are using the sp_configure system stored procedure to change the setting, you can change max degree of parallelism only when show advanced options is set to 1. The setting takes effect immediately (without restarting the MSSQLSERVER service). The following example sets the max degree ...
Some examples are Recompile, MAXDOP, OPTIMIZE FOR UNKNOWN. In this article, we will explore the query hint OPTION (FAST ‘N’) to improve the performance of a query for retrieving the specific number of rows quickly along with its impact. Pre-requisites In this article, I will use the...
The max degree of parallelismoption is set to 1. Note If MAXDOP query option is used, then SQL Server will not ignore the cost-threshold-for-parallelism value. The cost threshold for parallelism option is an advanced option. If you are using the sp_configure system stored procedure to change...
Try to use as below: (The below is an example)prettyprint 複製 create function fn_name() returns table as Return( With cte As (Select * From spt_values) Select * From cte ) --Usage: Select * From fn_name() Option(MAXRECURSION 0) ...
Provide the partition numbers for several individual partitions separated by commas, for example:ON PARTITIONS (1, 5). Provide both ranges and individual partitions, for example:ON PARTITIONS (2, 4, 6 TO 8). <range>can be specified as partition numbers separated by the word TO, for example...

Use MAXDOP to limit the number of processors used in a parallel plan execution. The maximum is 64 processors.max_degree_of_parallelism can be:1: Suppresses parallel plan generation. >1: Restricts the maximum number of processors used in a parallel index operation to the specified number. 0 (...
