Hi,

ALTER TABLE MyTable
ALTER COLUMN OldCol1 bit NOT NULL

ALTER MyTable
ADD CONSTRAINT OldCol1ShouldBeFalse DEFAULT 0 FOR OldCol1

I set default to 0 if no value is supplied to this column ...
But now when i try to insert a row into this table without supplying any value to this column ..

I was expecting that default should set to 0 automatically .. but it throwing an exception that unbale to insert null to this column .. why so ..?? it should insert my default value ..

Because you are passing null for the column. Post the sql you are using to insert.

Hi torakami.

This is how the SQL statement should be looking like for setting the Default value of a column to Zero in SQL Server.

SQL

ALTER TABLE [dbo].[MyTable]
ADD  CONSTRAINT [OldCol1ShouldBeFalse]  DEFAULT ((0)) FOR [OldCol1]

Try this one and let us know the result.

Thanks,
RelicV
