- Troubleshooting MySQL installation errors on Windows
- Common problems with installing MySQL on Windows include the service cannot be started, the port is occupied or the configuration failed. The solutions are as follows: 1. When encountering "MySQL80 service cannot be started", you should stop and delete the old service, clean up residual data, or use the "Remove" function that comes with the installer; 2. If an error is reported as "Error:1053" when starting the service, you need to check the log to confirm the port conflict and modify the port number in my.ini; 3. When the configuration wizard prompts "Service not responding", check and end the unresponsive mysqld.exe process, or manually run mysqld--console to view the output; 4. If the connection to the database is denied, you can use the password-free login method to reset the root user password.

- mysql tutorial for data analysis
- To use MySQL for data analysis, systematic learning is required. First, design a data structure suitable for analysis: use wide tables and pre-aggregated fields to appropriately redundant data, such as merging orders and user information; modeling time dimensions separately, such as adding date_type fields or date dimension tables; using partition tables to improve efficiency, especially when processing log data, partitioning by date. Secondly, master the key SQL skills: use GROUPBY to cooperate with SUM/COUNT for statistics; use CASEWHEN classification, such as dividing user activity levels; use DATE_FORMAT/WEEK to slice by time; use window functions such as ROW_NUMBER/RANK to rank, such as checking the top three products in each city's sales. Finally optimize query performance: in user_i
