Try this,

ALTER TABLE STUDENT ADD CONSTRAINT CONS_DF_RESULT DEFAULT N'Pass' FOR Result;

Thanks for reply Syed. The query is execute successfully, but its not updated for already existing records.

A simple Update is required to update existing records.

UPDATE STUDENT
SET Result = 'Pass'
WHERE RESULT IS NULL;

What value is set in Result for existing records?

Member 10021658 11-Sep-14 3:05am

datatype is varchar(50) and Allow Nulls is checked

Member 10021658 11-Sep-14 3:26am

But I have using these query update student set result='Pass' where result=''
Its working properly. But before I have tried to insert record using insert query constraint like CONS_DF_RESULT its not inserted default value, but using gui mode its working.

Thanks for reply Griff. Whenever I have tried this one ALTER TABLE Student ALTER COLUMN Result SET DEFAULT 'Pass', I got the error message like Msg 156, Level 15, State 1, Line 1
Incorrect syntax near the keyword 'SET'.

I think it is working on empty table only.

Manikandan MAC 11-Sep-14 7:43am

Its not working, shows error,

Msg 156, Level 15, State 1, Line 2
Incorrect syntax near the keyword 'set'.

I hope that Solution 1 & 3, will not work.

Solution 2 is working good,
