             Summary: Convert TINYINT and SMALLINT catalyst properly in MySQL 
JDBCv2 connector
                 Key: SPARK-45561
                 URL: https://issues.apache.org/jira/browse/SPARK-45561
             Project: Spark
          Issue Type: Bug
          Components: Spark Core
    Affects Versions: 3.5.0
            Reporter: Michael Zhang


MySQL dialect currently incorrectly converts catalyst types `SMALLINT` and 
`TINYINT` to BYTE and INTEGER in mySql. However, MySQL doesn't have a byte type 
and it also supports SMALLINT and TINYINT as types.
