How to delete a specific column data form a entity.

I have a entity class named Agent having fields Id,Name,Code,Skill ...etc. I wants to delete only the Skill from a row so I use Query like "Delete a.Skill from Agent a where a.Id = 112" but It gives error like "Unexpected query token 'agsk' (FROM is expected)".

How to resolve it.

Thank You

DELETE queries are for deleting complete objects (rows).

You may use an UPDATE query instead and set the field (column) to null.

Ok Tank you
