Study time also used and not quite understand, after work completely did not use and do not know the use of the scene
Do you know how to use the view?
The scenes used by the view are generally:
1, do not want visitors to get the entire table information, only to expose some fields to the visitor, so build a virtual table, that is, the view.
2, the query data from different tables, and respondents want to query in a unified way, so you can also set up a view, multiple table query results together, the query only need to directly from the view to obtain data, do not have to consider the data from the different tables brought about by the differences.
Is this view created in the database, not in code?
In other words, created well in advance?
Yes, this is the database provides the function, has the corresponding syntax support, you can search for a bit.
View of the database who used it? Why did you work for 2 years and have never seen a need for a view?
