如何使用psql命令在PostgreSQL中执行Oracle的DESCRIBE TABLE?


当前回答

Use this command 

\d table name

like 

\d queuerecords

             Table "public.queuerecords"
  Column   |            Type             | Modifiers
-----------+-----------------------------+-----------
 id        | uuid                        | not null
 endtime   | timestamp without time zone |
 payload   | text                        |
 queueid   | text                        |

Use this command

like 

\d queuerecords

             Table "public.queuerecords"
  Column   |            Type             | Modifiers
-----------+-----------------------------+-----------
 id        | uuid                        | not null
 endtime   | timestamp without time zone |
 payload   | text                        |
 queueid   | text                        |
 starttime | timestamp without time zone |
 status    | text                        |

使用以下SQL语句

SELECT DATA_TYPE 
FROM INFORMATION_SCHEMA.COLUMNS 
WHERE table_name = 'tbl_name' 
AND COLUMN_NAME = 'col_name'

若替换tbl_name和col_name,它将显示您要查找的特定列的数据类型。

下面的命令可以简单地描述多个表

\dt <table> <table>

下面的命令可以详细描述多个表:

\d <table> <table>

下面的命令可以更详细地描述多个表:

\d+ <table> <table>

您可以使用此选项:

SELECT attname 
FROM pg_attribute,pg_class 
WHERE attrelid=pg_class.oid 
AND relname='TableName' 
AND attstattarget <>0; 

尝试以下操作(在psql命令行工具中):

\d+ tablename
