JAVA learning lesson 38th (Common Object API)-set framework (6)-Map set and common methods
1. Map set features
The Map set (double row set) adds one element at a time, and the Collection set (single column set) adds one element at a time.Interface Map
Actually, key-value pairs are stored.
Features:
Objects that map keys to values. A ing cannot contain duplicate keys. Each key can only be mapped to one

Entity Framework 6.x implements the SQL function for record execution, entity6.x
When using Entity Framework, Model is often manipulated for a lot of time, and SQL statements are not written. Sometimes, for debugging or optimization, you also need to track the SQL statements automatically generated by Entity framework
Entity Framework 6 Recipes 2nd Edition (12-3), entityrecipes
12-3. database connection logs
Problem
You want to record logs for each connection and disconnection from the database
Solution
EF exposes a StateChange event for the DbContext connection. We need to handle this event and record logs for each connection and disconnection with the database.
Suppose our model is shown in Figure 12-3. in the Listing

10-5. Use custom functions in the storage model
Problem
You want to use udfs in the model instead of stored procedures.
Solution
Assume that our database has a member (members) and a messages data table, as shown in Figure 10-4:
Figure 10-4.A simple database
[' params '])) { $params = $data [' params ']; } /* If both class and function do not exist, the hook program cannot be located and returned directly to the */ if ($class = = = False and $function = = = False) { return FALSE; }
(5). Set the execution flag in_progress, and perform the hooks in both cases:

]If the parameter is a pointer and only used for input, you should add const before the type to prevent the pointer from being accidentally modified in the function body. Example: void stringcopy (char * strdestination, const char * strsource); L
Rule 6-1-4
]If the input parameter is passed as a value, you should use the "const " method to transfer the object. This saves the construction and analysis proce
Use a prototype instance to specify the type of the object to be created, and copy the prototype to create a new object.
