Could not create constraint. See previous errors.

Error Message:
Msg 1750, Level 16, State 0, Line 1
Could not create constraint. See previous errors
.

Severity level:
16.

Description:
This error message appears when as a result of a previous error a constraint cannot be created.

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

Resolution:
Error 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. The root cause for the previous error must be corrected so that the constraint can be created successfully.

Versions:
All versions of SQL Server.

Example(s):
CREATE TABLE #t
(
 t1 TIMESTAMP NOT NULL DEFAULT 0
)

Remarks:
In the above example we try to create a DEFAULT constraint for a column of the TIMESTAMP data type. Because you cannot create such constraints for columns of that type, the error 1755 is raised. And because the constraint wasn’t created successfully, this error is also raised.
