### What problem does this PR solve? Issue Number: close #67349 Problem Summary: The FE wrote a hardcoded 255 into the length field of every CHAR/VARCHAR/STRING column-definition packet, regardless of the length declared in the DDL. Clients that size buffers from result-set metadata (e.g. Connector/ODBC) therefore silently truncated longer string values. This change makes getMysqlTypeLength() report the declared length for CHAR/VARCHAR and caps the unbounded STRING type at MAX_VARCHAR_LENGTH (65533) so the 4-byte length field stays within MySQL TEXT semantics. ### Release note None ### Check List (For Author) - Test: Unit Test (MysqlSerializerStringLengthTest) - Behavior changed: No - Does this need documentation: No -- This is an automated message from the Apache Git Service.
