Error validating the default for column id newsequentialid
OK, newsequentialid() works, but I was suspecting a "1" for the first record, but the value saved in ID is "395c49aa-b1c3-dc11-8c1e-000475cd259f" If I used newid() instead, would I get a 1?This is because the data-type uniqueidentifier is used (Guid).The UI team doesn't exactly have a whole lot of guys on it so they get to what they can as dictated by management (if it isn't Azure at the moment it isn't getting fixed).I have already asked what amounts to one half of the question here, but I am hoping someone in this forum can answer the other half, involving MS SQL server specifically.I would like to know how to modify a foreign key property for the foreign key, but both attempts came back with “Error validating the default for column 'column'.” I am hoping that someone might be able to help me to add a default value to a non-nullable CREATE TRIGGER t_replace_null_guid_with_default ON dbo.t INSTEAD OF INSERT AS BEGIN INSERT INTO dbo.t (tid, ggid) SELECT tid, COALESCE(ggid, '00000000-0000-0000-0000-000000000000') FROM inserted; END ; The point of the default value is to provide a value when an INSERT has values for some of the columns of the table (the rest get their respective defaults).ADD statement in ISQL, the column is initialized to 0 or blank depending on the data type of the column.My other question tried to focus on the MVC Code-First migration itself, but I cannot wait around for an answer in terms of this project (although it will be useful for future projects), so this question on this forum involves the MSSQL server itself.
如何设定DEFAULT VALUE为NEWSEQUENTIALID()通过UI的方式设定默认值时，由于SQL SERVER 2005的BUG（即使是SP2也没有解决），导致我们设置了默认值为NEWSEQUENTIALID()保存时会出现以下错误：Warning were encountered during the pre-save validation process, and might result in a failure during save.
