SELECT TABLE_NAME
FROM INFORMATION_SCHEMA.TABLES
WHERE TABLE_TYPE = 'BASE TABLE'
ORDER BY TABLE_NAME

对于postgres，它将是:

SELECT table_name
FROM INFORMATION_SCHEMA.TABLES
WHERE table_schema  = 'your_schema' -- probably public 

对于Mysql，你可以做的很简单。显示表;

SELECT TABLE_NAME
FROM your_database_name.INFORMATION_SCHEMA.TABLES
ORDER BY TABLE_NAME;

可能是因为不同的sql dbms处理模式的方式不同。

试试下面的方法

对于SQL Server:

SELECT TABLE_NAME
FROM INFORMATION_SCHEMA.TABLES
WHERE TABLE_TYPE = 'BASE TABLE' AND TABLE_CATALOG='dbName'

MySQL:

SELECT TABLE_NAME 
FROM INFORMATION_SCHEMA.TABLES
WHERE TABLE_TYPE = 'BASE TABLE' AND TABLE_SCHEMA='dbName' 

对于Oracle，我认为等效的方法是使用DBA_TABLES。

根据Michael Baylon的回答，我需要一个包含模式信息的列表，这就是我修改他的查询的方式。

SELECT TABLE_SCHEMA + '.' + TABLE_NAME as 'Schema.Table'
  FROM INFORMATION_SCHEMA.TABLES
WHERE TABLE_TYPE = 'BASE TABLE' AND TABLE_CATALOG = 'dbName'
  ORDER BY TABLE_SCHEMA, TABLE_NAME
