  • Artikkeli

Applies to: SQL Server Azure SQL Managed Instance

This function returns the number of attempted connections - both successful and unsuccessful - since SQL Server was last started.

Transact-SQL syntax conventions

Syntax

@@CONNECTIONS

Return types

integer

Remarks

Connections are different from users. An application, for example, can open multiple connections to SQL Server without user observation of those connections.

Run sp_monitor for a report containing several SQL Server statistics, including count of connection attempts.

@@MAX_CONNECTIONS is the maximum allowed number of simultaneous connections to the server. @@CONNECTIONS increments with each login attempt; therefore, @@CONNECTIONS can exceed @@MAX_CONNECTIONS.

Examples

This example returns the count of login attempts as of the current date and time.

SELECT GETDATE() AS 'Today''s Date and Time',   
@@CONNECTIONS AS 'Login Attempts';

Here's the result set.

Today's Date and Time  Login Attempts
