SQL: When using INFORMATION_SCHEMA.TABLES How do I specify a database name and a server name?

Question

In the code below, I am able to specify the table name and schema that I want to query with Table name and Table schema. How do I specify the database name and server name that I want to query?

I have tried DATABASE_NAME, DB_NAME and SERVER_NAME. None of them work.

 SELECT COUNT(1) AS TABLECOUNT FROM INFORMATION_SCHEMA.TABLES WHERE 
 TABLE_SCHEMA = 'dbo' AND TABLE_NAME = '[TABLE_NAME]

Answer 1

Here is how you can select database, table and server-name :

SELECT COUNT(1) AS TABLECOUNT, @@SERVERNAME as 'serverName' FROM INFORMATION_SCHEMA.TABLES
WHERE TABLE_SCHEMA = 'dbo' AND TABLE_NAME = 'CALCULATION_SCHEDULE' 
and @@SERVERNAME ='xx' and TABLE_CATALOG ='database name'

Answer 2

You need to use TABLE_CATALOG for passing database name. In SQL Server this column contains the database name that contains that table as shown below.

SELECT COUNT(1) AS TABLECOUNT FROM INFORMATION_SCHEMA.TABLES WHERE 
TABLE_SCHEMA = 'dbo' AND TABLE_NAME = 'CALCULATION_SCHEDULE'
AND TABLE_CATALOG = '<Your Database Name>'

You can also pass directly server name and database name as shown below.

SELECT * FROM [ServerName].[DatabaseName].INFORMATION_SCHEMA.TABLES where ---.

Answer 3

There is no table or view that enumerates all tablesof all databases, you have to explicitly specify database:

1. Directly in query

   SELECT COUNT(1) AS TABLECOUNT FROM [dbname].INFORMATION_SCHEMA.TABLES WHERE TABLE_SCHEMA = 'dbo' AND TABLE_NAME = 'CALCULATION_SCHEDULE' ;

2. Via "USE"

    USE [dbname] SELECT COUNT(1) AS TABLECOUNT FROM INFORMATION_SCHEMA.TABLES WHERE TABLE_SCHEMA = 'dbo' AND TABLE_NAME = 'CALCULATION_SCHEDULE' ;

3. In your connection string

Regarding a Server Name, it is possible only via system variables like @@SERVERNAME or SERVERPROPERTY('ServerName'):

WHERE TABLE_SCHEMA = 'dbo'
AND TABLE_NAME = 'CALCULATION_SCHEDULE'   
AND SERVERPROPERTY('ServerName') = 'YourServer' ;
