Computed column ‘%.*ls’ in table ‘%.*ls’ cannot be persisted because the column is non-deterministic.

Error Message:
Msg 4936, Level 16, State 1, Line 1
Computed column ‘%.*ls’ in table ‘%.*ls’ cannot be persisted because the column is non-deterministic.

Severity level:
16.

Description:
This error message appears when you try to create a persisted computed column whose definition is non-deterministic.

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 can be fixed by the SQL Server user. The statement cannot be executed this way. You cannot create a persisted non-deterministic computed column.

Versions:
This error message was introduced with SQL Server 2000.

Example(s):
IF OBJECT_ID (‘dbo.t’) IS NOT NULL
    DROP TABLE dbo.t;
GO
CREATE TABLE dbo.t
(
    c1 float,
    c2 AS GETDATE() persisted
);

Remarks:
In the above example we try to create a persisted computed column with a definition of GETDATE(). This raises the error.
