实际就是从数据字典中查询出结果,展示出来.
其中主键字段会加粗显示.
页面效果如下(其中的浮层效果请见 http://hilltop.iteye.com/blog/1678368)
sql语句如下
SELECT dense_rank() over(ORDER BY a.table_name) AS seq, a.table_name,
d.comments AS table_comments, a.column_id, a.column_name,
a.data_type || nvl2(a.char_col_decl_length,
'(' || a.char_col_decl_length || ')',
'') AS data_type,
DECODE(a.nullable,'N','N',NULL) as nullable, c.comments AS col_comments,
nvl2((SELECT i2.column_name
FROM user_ind_columns i2, user_indexes i1
WHERE i2.index_name = i1.index_name
AND i2.table_name = i1.table_name
AND i1.table_type = 'TABLE'
AND i1.uniqueness = 'UNIQUE'
AND i2.table_name = a.table_name
AND i2.column_name = a.column_name),'Y',NULL) AS is_pk
FROM user_tab_columns a, user_tables b, user_col_comments c, user_tab_comments d
WHERE a.table_name = b.table_name
AND a.table_name = c.table_name(+)
AND a.column_name = c.column_name(+)
AND a.table_name = d.table_name(+)
ORDER BY b.table_name, a.column_id
page的配置如下
