使用

• 使用PLSQL工具查询表结构，SQL语句如下

  SELECT 
      B.TABLE_NAME AS '表名',
      C.COMMENTS  AS '表说明', 
      B.COLUMN_ID AS '字段序号', 
      B.COLUMN_NAME  AS '字段名', 
      B.DATA_TYPE AS '字段数据类型', 
      B.DATA_LENGTH  AS '数据长度', 
      B.DATA_PRECISION AS '整数位',        
      B.DATA_SCALE  AS '小数位',        
      A.COMMENTS  AS '字段说明'   
  FROM 
      ALL_COL_COMMENTS A, 
      ALL_TAB_COLUMNS B, 
      ALL_TAB_COMMENTS C 
  WHERE 
      A.TABLE_NAME IN (SELECT U.TABLE_NAME FROM USER_ALL_TABLES U)    
      AND A.OWNER = B.OWNER    
      AND A.TABLE_NAME = B.TABLE_NAME    
      AND A.COLUMN_NAME = B.COLUMN_NAME    
      AND C.TABLE_NAME = A.TABLE_NAME    
      AND C.OWNER = A.OWNER    
      AND A.OWNER = 'xxx_db_name' --其中xxx_db_name为DB用户名
      AND A.TABLE_NAME like '%xxx_table_name%' --xxx_table_name为表名称
  ORDER BY A.TABLE_NAME, B.COLUMN_ID;
