reduced or the query is canceled. You can also set immediately matching identified queries through text or execution plans within a period of time, to avoid excessive resource consumption during the identification manual marking of queries. By using the QUERY WATCH com- mand, you can mark queries based on the SQL text, SQL Digest, or execution plan. The queries that match the mark can be downgraded or canceled, achieving desensitization supports removing sensitive data when users view logs, implemented by marking SQL text information in log files. You can control whether to mark log information to enable secure use of

Therefore, it is recommended to use Prepared Statements instead of regular exe- cution from a text file and reuse Prepared Statements to execute directly. This avoids the overhead of repeatedly parsing Connector/J, only client-side statements are preprocessed, and the statements are sent to the server in a text file after ? �→ is replaced on the client. Therefore, in addition to using the Prepare API, you also
