Configuration Functions (Transact-SQL)

[!INCLUDE SQL Server Azure SQL Database Azure SQL Managed Instance FabricSQLDB]

These scalar functions return information about current configuration option settings:

• @@DATEFIRST
• @@DBTS
• @@LANGID
• @@LANGUAGE
• @@LOCK_TIMEOUT
• @@MAX_CONNECTIONS
• @@MAX_PRECISION
• @@NESTLEVEL
• @@OPTIONS
• @@REMSERVER
• @@SERVERNAME
• @@SERVICENAME
• @@SPID
• @@TEXTSIZE
• @@VERSION

All configuration functions operate in a nondeterministic way. In other words, these functions do not always return the same results every time they are called, even with the same set of input values. See Deterministic and Nondeterministic Functions for more information about function determinism.
