背景

• 有一次需要查询Oracle数据库中的所有表接口并且导出excel，方法记录如下

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;
