## Proposed changes Fix FE reports hardcoded field length 255 for all VARCHAR columns in the MySQL protocol column definition packet. ### Problem When connecting via MySQL connector/ODBC, VARCHAR columns always show length 255 instead of the actual defined length. The `getMysqlTypeLength` method in `MysqlSerializer` had a hardcoded `return 255` in the default case for VARCHAR/CHAR/STRING types, ignoring the actual type length. ### Solution Added explicit cases for `VARCHAR`, `CHAR`, and `STRING` in `getMysqlTypeLength` to return `type.getLength()` instead of the hardcoded 255. This reports the actual column length (e.g., 10 for VARCHAR(10)) in the MySQL protocol column definition packet. ### Changes - `fe/fe-core/src/main/java/org/apache/doris/mysql/MysqlSerializer.java`: Added explicit cases for VARCHAR, CHAR, STRING to return actual type length - `fe/fe-core/src/test/java/org/apache/doris/mysql/MysqlSerializerVarbinaryTest.java`: Updated test to expect actual VARCHAR length (10) instead of 255 Issue: #67349 -- This is an automated message from the Apache Git Service.
