SQL Server Indexed Views vs Oracle Materialized View

由 自作多情 提交于 2020-01-02 07:29:16
问题 I know materialized view and I'm using it. I have never used indexed views but I will. What are the differences between them ? 回答1: SQL Server’s indexed views are always kept up to date. In SQL Server, if a view’s base tables are modified, then the view’s indexes are also kept up to date in the same atomic transaction. Oracle provides something similar called a materialized view. If Oracle’s materialized views are created without the **REFRESH FAST ON COMMIT** option, then the materialized

问题 I am trying to get the data using the Materilize css's chips. But no data is received when I try to submit it using a form. I checked that the input fields value was null once I added the chips.

T-SQL CTE materializing techniques not working on SQL Server 2012

由 不打扰是莪最后的温柔 提交于 2019-11-28 08:46:17
I have to use the following techniques to materialized my CTEs and increase the view performance: WITH CTE AS( SELECT TOP 100 PERCENT ORDER BY ... ) WITH CTE AS( SELECT TOP 2147483647 ORDER BY ... ) Now, neither of this ways works.

This way, the server is forced to materialize the TVF's results into a table variable. Also, you could try using declarative constraints when declaring the this table type (PRIMARY KEY, UNIQUE, CHECK) to improve the
