Error Message:
Msg 15143, Level 16, State 1, Line 27
'%s' is not a valid option for the @updateusage parameter. Enter either 'true' or 'false'.

Severity level:
16.

Description:
This error message appears when you try to use an invalid option for the @updateusage parameter of the sp_spaceused procedure.

Consequences:
The T-SQL statement can be parsed, but causes the error at runtime.

Resolution:
Errors of the Severity Level 16 are generated by the user and are corrigible by the user. The statement cannot be executed this way. Valid values for the @updateusage parameter are only 'TRUE' and 'FALSE'.

Versions:
All versions of SQL Server.

Example(s):
USE Northwind;
EXEC sp_spaceused @objname = N'Northwind', @updateusage = 'TREU'

Remarks:
in the above example we try to execute the sp_spaceused procedure with the invalid value "TREU* for the @updateusage parameter. This raises the error.
