Select TABLE_NAME,COLUMN_NAME,DATA_TYPE
From user_tab_columns
Where column_name In --(Select keyword From v$reserved_words)

Or column_name Like '% %'
--检查数据库中相同名字不同类型的字段名
select a.column_name,a.data_type,b.data_type From
(select distinct column_name,data_type from
all_tab_columns Where TABLE_NAME Like 'T%') a,
(select distinct column_name,data_type from
all_tab_columns Where TABLE_NAME Like 'T%') b
where a.column_name=b.column_name and a.data_type<>b.data_type
--检查数据库中相同名字相同类型不同长度的字段名
select a.column_name,a.data_type,b.data_type,
a.data_length,b.data_length From
(select distinct column_name,data_type,
data_length from all_tab_columns Where TABLE_NAME Like 'T%') a,
