Question

How do i truncate the table which has constraints?

My Table looks like below. I need to truncate the data from this table So that I could load the data from prod data base.
This table has constraints which does not let me truncate the data.

Please help me with the query necessary to truncate this table.

[ID] [int] IDENTITY(1,1) NOT NULL,
[Text] [nvarchar](max) NOT NULL,
