Only when the column list is used and identity_insert is on

To add data to the ID column, use the following method:

Set identity_insert pcinfo on -- set the ID column to display the added data
Insert into pcinfo (PCID, pcuse, pcnote) values (, 1, 'aaa') -- PCID is the ID column
Set identity_insert pcinfo off -- set the ID column to display the added data

Note: To display the added data for the ID column of a table, you must display the fields to be added after the table in the insert statement,

For example: pcinfo (PCID, pcuse, pcnote), if you only write pcinfo, you still cannot add data for the PCID display.
