the three compression methods before compressing the file
The approximate compression rate, history record and favorites function, the compression rate is quite high, and the resource occupies relatively few, fixed compression,
Multimedia compression and multi-volume self-release compression are not available in most compression tools; it is simple and convenient to use, with few configuration options, only

This article mainly introduces the script for exporting user permission settings in MySQL. to set the export permission for data in the user table, you can refer to the user and permission in the source database when migrating the MySQL database. For this migration, we can obtain the user's related permissions from the mysql. user table to generate corresponding SQL statements, and then execute the generated SQL statements on the target server. This article provides a script for extracting user
generated SQL statements on the target server. This article provides a script for extracting User Permissions and a demonstration.
1. Generate a script for User Permissions
