【问题描述】*：
查询表字段英文，字段注释，主键标识，是否自增后，在 debeaver 中可以查询都正确的信息，但是通过 mybatis 查询，字段注释就为 null，并且原本主键标识为 Y 的，反而为 N,目前不确定是代码的问题还是某个地方的问题 ，sql 如下
SELECT
'Y' AS allowEdit,
utc.COLUMN_ID AS showOrder,
utc.DATA_TYPE AS inputBoxType,
CASE
WHEN uc.CONSTRAINT_TYPE = 'P' THEN 'Y'
ELSE 'N'
END AS primaryIdentity,
utc.TABLE_NAME AS dataSourceTable,
utc.COLUMN_NAME AS columnName,
ucc.COMMENTS AS columnZhName,
CASE
utc.DATA_TYPE
WHEN 'decimal' THEN 'decimal'
WHEN 'int' THEN 'int'
WHEN 'bigint' THEN 'bigint'
WHEN 'datetime' THEN 'datetime'
ELSE 'varchar'
END AS dataType,
CASE
WHEN tmp.INFO2 = 1 & 0x01 THEN 'Y'
ELSE 'N'
END AS isAutoIncrement,
CASE
WHEN utc.NULLABLE = 'Y' THEN 'Y'
ELSE 'N'
END AS isMayNull
