"definition tables" that contain only fixed states or types. Enum and set columns are suitable for storing fixed information, such as ordered state, product type, and gender.String typeIf possible, you should avoid using string types as identity columns because they are very space-consuming and often slower than numeric types.There is also a need to pay attention to a completely "random" string, such as a string produced by MDS (), Shal (), or UUID (

The main difficulty of integration algorithm is how to integrate the independent weak learning models and how to integrate

Requirement: Import multiple NTS that meet the conditions in the oracledata database into a csv1_file and store them with the table name. CSV as the file name.
Implementation: It is implemented through the UTL_FILE function in the stored procedure. The exported csv file is placed in the directory created in advance.
Usage: Use the following command to pre-execute the SQL script
SELECT 'exec SQL _to_csv (''select * from' | T. TABLE_NAME |

Spotlight In Mac is very convenient, but the amazing problem is that the service has been disabled. I searched for the Solution Below and tried it.
Sudo mdutil-I off/
This command is used to disable the index.
Sudo mdutil-E/This command is used to delete an index.Sudo mdutil-I on/This command is used to re-create an index.

MappingAfter the database is connected, you need to map the classes and data you have defined. The corresponding ing method (MongoDB. bson. dll) is provided in the driver: Bsonclassmap. registerclassmap {Cm. automap ();}); In addition, you can directly set the ID and ID generation method during mapping: Bsonclassm
