SQL Server 查询以查找所有当前数据库名称

Question

我需要一个 SQL 查询来查找现有数据库的名称。

Answer 1

这是一个查询，用于在一个 Sql 引擎中显示所有数据库

Select * from Sys.Databases

Answer 2

SELECT name  
FROM sys.databases

You'll only see the databases you have permission to see.

Answer 3

另一个要添加到组合中：

EXEC sp_databases

Answer 4

I don't recommend this method... but if you want to go wacky and strange:

EXEC sp_MSForEachDB 'SELECT ''?'' AS DatabaseName'

or

EXEC sp_MSForEachDB 'Print ''?'''

Answer 5

You can also use these ways:

EXEC sp_helpdb

and:

SELECT name FROM sys.sysdatabases

SELECT DISTINCT TABLE_SCHEMA from INFORMATION_SCHEMA.COLUMNS

Answer 8

SELECT datname FROM pg_database WHERE datistemplate = false
