數據庫導出表結構sql語句:
select column_name as 字段類型, column_type as 數據類型, data_type as 字段類型, character_maximum_length as 長度, is_nullable as 是否為空, column_default as 默認值, column_comment as 備注 from information_schema.columns where table_schema = '數據庫名稱' and table_name = '表名稱'
查詢出表結構,可以點擊導出結果將查詢的結果導出
也可以:
select column_name as 字段類型, column_type as 數據類型, data_type as 字段類型, character_maximum_length as 長度, is_nullable as 是否為空, column_default as 默認值, column_comment as 備注 from information_schema.columns where table_schema = '數據庫名稱' and table_name = '表名稱' into outfile 'C:/Users/Admintor/Desktop/abc.xls' -- 導出到桌面的Excel表格
執行sql語句
如果執行這個sql語句報錯時:--secure-file-priv
mysql限制了導入與導出的目錄權限 需要修改mysql.ini配置文件
進入mysql執行show variables like '%secure%'; 發現secure_file_priv路徑為NULL
修改mysql.ini中,添加一句
secure-file-priv = C:/Users/權煥旭/Desktop/
重啟MySQL,然后再次查看當前的secure-file-priv
show variables like '%secure%';
然后執行sql語句 可以正常導出
還可以:
新建一個excel表格,將查詢的數據全選后右擊選擇復制為-制表符分隔值(欄位名和數據),復制到Excel表格中
