## Proposed changes Issue Number: close #xxx This PR enhances the support for auto-increment columns and default value columns in the MySQL JDBC catalog of Doris, mainly via the following changes: In JdbcMysqlClient, I've added methods to retrieve auto-increment and default value columns from MySQL. These columns are then mapped into Doris metadata to make them visible to users. When handling the InsertStmt into an execution plan, Doris used to automatically fill in NULL or default values for columns not specified in the InsertStmt. However, in the JDBC catalog, we don't need Doris to handle these unspecified columns, so I've made changes to skip them directly. For the insert prepared statement required for writing, our previous behavior was to obtain all columns for placeholders. So, the change I made is to pass in the columns processed by the execution plan during the sink task generation stage for dynamic generation. ## Further comments If this is a relatively large or complex change, kick off the discussion at [d...@doris.apache.org](mailto:d...@doris.apache.org) by explaining why you chose the solution you did and what alternatives you considered, etc... -- This is an automated message from the Apache Git Service.
